What blows my mind is how easily public opinion was turned against putting people on the Moon, immediately after putting people on the Moon! Today's technology is 500 years behind what it would have been had it continued.
@@shubhamkumar6689 Apollo was fast, but we should not forget they also had a far higher risk level compared to space travel in the 21st century. The risk level which was acceptable back then (Apollo was cutting edge and at the limit which was possible) wouldn't be accaleptable any more today. At the end the Apollo program had a better safety record than originally expected.
I understand that the IDS standard includes provision for the fitting of fuel/air/liquid umbilicals around the docking mechanism, but actual specifications are up to individual programs for now
I'd like to think the specs would be made international so that if needs must craft from different continents could assist each other in a tough situation. NASA's non-cooperation pact be damned.
This is a MUCH better lander than the previous national team pitch. Plus, single fuel hydrolox system means the entire lander can be refueled on the lunar surface with the suspected ice water on the surface. Hope we see this through
Eh, not wild about using such a precious resource as fuel. The mass of ice you would need to pick up only to throw it all away? Not great. Rather use it as in situ atmosphere for permanent base construction.
Blue Origin rocket: still not ready Blue Origin engines: still not ready Blue Origin lander: still just fancy marketing posters how many years has it been now?
I'm really excited that this return to the moon could actually produce and test new technologies in spaceflight. It that's the case it might actually be worth the cost.
I agree. Orbital refueling of cryogenic fuels and oxidizer is going to be huge. Plus, the more we learn about how to utilize resources that don't come directly from Earth, the better. Mars will have plenty of differences, but the less we have to ship in, the better. They're still both barren rocks with little or no atmosphere and magnetosphere. It will still probably be a hundred plus years until either are truly self-sustaining. I'm talking to where if Earth just vanished, they'd be fine

We have a valid reason to return to the Moon to stay. The ice in the polar craters is supposed to be an archive of Earths climate and life, that reaches eons further back, than anything down here. There even can be samples of the proto life.
I've been making landers in KSP like this for a while because not only is it easier for landing and egress, but I often make the command pod into a dettachable rover. This way I can take a large rover all the way to the mun or duna and bring it all the way back to Kerbin with tons of science and recovering the expensive rover components.
Honestly, I don't see the appeal of bringing back a rover. There's plenty of vehicles on Earth, and they're cheap to build here (or on Kerbin). Better to leave the rover where you can use it again, even if you need to have a small ferry mission to move it to the new site.
Haha this is brilliant. I used to just make a huge tanked lander for biome hopping. But a rover command pod can reduce hopping by a lot if you keep landing on biome borders.
@@absalomdraconis It's not about bringing back a rover. It's about saving on mass by converting the command pod in to a rover. I do see the appeal of leaving behind equipment. Even if you don't use it. You can always recycle it for resources on a future colony.
@@absalomdraconis Why build anything in ksp? Sure there are other mission architectures with their own respective benefits. But why reutrn the rover? First of all, because it's fun, it's just fun to add the additional constraint that the mission must be fully reusable. Second of all, because in carreer mode sometimes the price of those science parts adds up on the rocket, so you can save money by bringing them back.
While I like the Starship, I am glad that there will be two teams working on solving the key problems that the Artemis mission profile calls for, namely refueling in orbit.
Also if one fails hopefully the other won't and Starship in 2023 comes off more as an uncrewed cargo transport/ base builder while this design is more crewed lander/ short term habtat.
@@LeftOverMacNCheese True but hopefully the AI driven design process being tested on the B-21 raider and gen 6 USAF fighter would be used to speed up this lander development.
Haven't gotten through the video yet, but Blue's new design really makes me wonder what they were thinking with the first one. With this they've shown they're clearly capable of coming up with a decent modern design, so what was with the previous Apollo-but-worse design?!!?!
The first one was a cash grab. This is trying to justify the existence of New Glenn. Once starship is operating there’s not going to be a good reason to use New Glenn for normal rocket launches so they need a specific application it exists for. This gives them the breathing room required to build an actual starship competitor.
If you see the first design was very similar to Apollo landers...It's logical Northrop Grumman was on board at the time...they were really good designing the Apollo landers...but this time NG is not on board....maybe this design is more risky but probably it works better
Why? No seriously, why? The design was half done and already had a negative payload mass fraction. Meaning it can deliver no payload to the moon. I mean it can but it can't get back into orbit. The fuel tanks would run dry on ascent. So why are you a fan of a lunar lander that failed the MOST BASIC requirement of making it to the moon and back. ALPACA was a PP presentation. Not even functional on paper. Even the Russians paper rockets at least work in theory. You and I could do better than handing in a failed project. "Hi, so I had no idea, this is my homework, I'd like a failing grade please". Oh and ridiculously overpriced. 6 billion for the engine to run dry half way to orbit. Then an awkward 10 minutes or so, while the astronauts fall back to the moon. Ah yes, what a design. It's actually the cheapest. It costs nothing and we're not going back. Artemis is cancelled. The money will go towards SLS, which will not be cancelled. It will become the new ISS access. The full upper stages will be left in orbit for future use.
@@221b-l3t all of this was fixed in the appendix p submission. Same capabilities as the blue design with a lower project cost and com. Equipment which actually meets the requirements and a schedule which doesn’t have “multiple contradictions”
Thanks for this. My heart sank when I heard the National Team had been selected, because their last effort was so dodgy. This seems a much better concept. I am still utterly convinced that between Boeing and Blue Origin the chances of this flying, or being able to deliver the goods promised, within a reasonable timeframe or budget are slim to none. Keep your fingers crossed Space X can make Starship work, I have a feeling the Artemis program will need quite a few of their lunar landers ...
@@land_and_air1250 The alpaca was not as good as this design. It is ok to be honest. A few posts have mentioned that BO needed this deal, so bezos likely funded a few billion on top of the government's price. A design with a bunch more money should be better. It sucks for dynetics, but the best design still has to win.
Hopefully the fixed price contract will motivate management to get things done instead of just scheduling preliminary design meeting and BS all day for decades.
Well that worked with Starliner... oh wait... Seriously though between Boeing and Blue Origin, this thing will cost three times what they bid and will not be ready 16 years from now. Bezos will have to sell some stock to cover the losses.
Thank you for including peripheral engines. I was in a distinct minority on this on some forums. Yes, I think the bulges we see are partially buried engine nozzles. There's even a hint of hoops on them. I'm wondering if they'll be canted outward slightly to reduce the area of plume that hits directly below the lander - to reduce the amount of regolith kick up.
If they are peripheral engines and canted out, then could they be placed further up near where the fuel tanks are located or would this make it hard to fit in the fairing. This is what people thought the original Starship illustration was doing. Maybe Blue will change the design again and put the tanks and engines on the side like the Alpaca. They could have two Blue Moon cargo versions connect to the sides of a Blue Moon crew version to make a single lander.
@@mannyalejo772 That's exactly what I was thinking they might do. This is an early render. Having the landing rockets up higher near the fuel tanks makes all kinds of sense: less intrusion into the crew cabin below, less excavation of regolith upon landing. For a 45 to 60-ton lander, exhaust excavation will probably become a serious issue (unlike the lighter landers that can just plop down on top of their engine bells)
I only wish jeff would show what’s going on at blue origin or at least post an update every once in a while. Just imagine so many more young people getting hooked to spaceflight
Reminds me of a concept lander I thought of with a torus habitat around a center engine with the propellant above. The propellant would act a shielding while on the surface. The engine hidden up inside would allow for a lower profile and being more compact and having a lower center of gravity in my design. Then at that less outward structure of landing legs would be needed. All contribute to making a lighter craft.
Although my faith in BO isn't super high, I'm really hoping they'll be able to see this through all the way to the moon and back. Even if they fall short, it's good to have some competition for SpaceX. And the insights & experience engineers will get with hydrogen will be incredibly valuable in the coming decade on earth as well, considering it has some role to play in energy transition plans of many countries.
With all the hydrogen leaks on SLS when on the pad with many available engineers with torque wrenches, it'll be interesting to see how that works on an automated system...
So far NASA have managed to demonstrate keeping cryogenic methane cooled on the ISS...for four months until the chiller broke. (Which meant they couldn't test actually transferring it between tanks.) So, keeping hydrogen chilled is probably doable, but it's going to take a few more years of testing before there's any useable hardware I think.
Originally, Blue complained about Starship needing on-orbit refueling and a massive elevator. I feel like once they got the chance to redesign for take two, they decided that refueling was doable, even with hydrogen, but that the elevator could never be made to work.
They needed complementary advantage, since they lost the "one" competition; stealing from ALPACA's playbook was quite natural. And, of course, it's to their merit that they learned from their mistakes, instead of just pushing the lobbying fan into overdrive.
@@timemachine1944 Nothing is simple tech when required to work flawlessly on the moon far away from help. It adds an extra mission critical component of moving parts that can break down and render the mission impossible to complete. Elevators on earth break down all the time!
@@Nethian78 It's a winch and a basket. Backup? Second winch. Backup? Block and tackle, hoist yourself up. Probably a little crank handle you can turn to manually ascend like on some service elevators. Just crank 500 times and you'll get there. But yeah a simple elevator is very low tech. Doesn't even need electricity for the last backup.
@@neniAAinen they instead chose to lobby in the proposal by bidding a price to NASA that they admit is half of the cost that it’s going to cost blue undercutting Dynetics who’s lander was cheaper in total cost but more expensive to NASA as they don’t have bezos bucks
@timemachine194 The elevator itself works fine once you've added redundancies with backup motors and whatnot, it's just that all that weight for the winch and basket to carry the crew is mass that can't be used to carry payload to the lunar surface. All that extra mass needs fuel to get it to the lunar surface and then back up into orbit to rendezvous with Orion, so that means there's that much less science payload that can be returned because you have to schlep the elevator back up with you. It's not a technology thing, it's a mass thing. Blue Origin solves that problem by putting the crew at the surface and eliminates the elevator altogether.
In Kerbal 1 this is how I generally did landers, with the descent engine and fuel tank above the crew and with small engines on the side at an angle. So that way you could ditch it on the surface and have a much lighter ascent stage, without having the crew way high up off the ground. (More stable, too)
There is an Airbus concept drawing of a new airplane with liquid hydrogen tanks over the passenger cabin. All I could think of is, go screw yourself, Airbus. And I've never flown.
Thanks for giving us a sneak peak at what it might be like. My favorite part is when the astronaut popped out on the lunar surface. Lots to do before any of our latest and greatest get to the moon!
Those strange things you refer to as radiators strike me as deflectors if the engines were positioned in the slots at the top of them. This would have the Starship HLS's advantage of keeping the concentrated exhaust plume away from the surface.
Very interesting possibility! I hope you're right. Exhaust excavation will probably be a problem with such a massive lander. Unless they clear and sinter a landing pad ahead of time...
one big advantage this has in the long term over starship and alpaca (both use methane) is that hydrogen can eventually be produced on the surface and then no refueling in space has to be done (if they manage to store it long enough between landings) because they can refuel enough for an ascent and another landing just on the surface alone. also it might be useable as a hydrogen transport system for a nuclear powered ship that is constucted unfueled in lunar orbit, even more if down the road they make a version that replaces the crew cabin with another hydrogen storage tank
75% of all known asteroids are carbonaceous, so I'm wondering if they might find carbon under the Moon's surface, and might be able to synthesize methane from carbon and hydrogen. Perhaps not though. The carbonaceous asteroids are clustered toward the outer edge of the main belt where the sun's heat doesn't affect them too much.
If you have multiple engines for redundancy, you probably want them close to the center. You want to be able to fire just two without creating a large moment.
And the solution is to angle them the right way. Look at the angle of the Space Shuttle Main Engines … they are not along the shuttle , but point roughly through the combined shuttle/fuel tank centre of mass, which means no angular momentum. That is also how you make a single booster for a rocket work.
feels like they for the first time thought a bit about the design instead of just putting 3 different legosets on top of each other and calling it done. much better than the previous one. maybe even the best design so far for this mission.
You mention a paper in the New Glenn fairing. Does it give an inside diameter, the usable payload space? On F9 and Atlas V this is 0.4m less than the outside diameter. I'm trying for a good figure for the crew quarters. If the legs don't fold completely underneath then it'll be be barely 6m, right? A little more otherwise.
45 Tons was the propellant mass 16 tons was the dry mass making a total mass of 61 tons. Dynetics has a total mass of 62 tons for same payload capacity as blue meaning that they gain nothing from the hydrogen and maybe less than nothing since they have a tug which provides support for delta v. Also the Dynetics lander is also 1 fuel using methane in the rcs thrusters which they’ve already tested and using a main engine which has been tested and both work. Dynetics has engine out capability as well as heavy shielding to protect the crew and tanks from rocks and debris from the lunar surface and landing legs which seems absent from the blue design
@scottmanley I'd be very interested in your take on the "it's tall and tilty" arguments being bandied around for both the Blue Origin and SpaceX proposals.
I'm sure that mod is based on the best data available, but also they might want to keep the poly count from getting too high. So I'd answer your question with "probably, but not definitely."

Agreed, Starship for Artemis 3, Blue Origin Lander for Artemis 4+, refueling at an international lunar gateway station - I love how messy everything is. Variety and competition is gonna help so much in the long run.
The moon should NOT be a bloody trading post for private enterprise … One faction within America is already privatizing another celestial body with neoliberal capitalism on behalf of the whole planet. Tell them NO Try searching anything from economist Michael Hudson or critiques of neoliberal ideology and you’ll get a sense perhaps for why some people like me are so steamed.
Hydrogen is difficult enough as it is to handle on Earth, let alone in orbit or on the Moon. But at least they've sorted out the ludicrously long ladder. To me, the Alpaca seemed to be the ideal solution, ticked all the boxes. It probably came down to which design would give jobs to enough people in sufficient states.
While I like Alpaca and NASA evidently loves the low-slung Alpaca design, Dynetics has apparently had a lot of problems making it work. It was too heavy to fly in the HLS Option A competition and had more problems than Blue Moon in the Appendix P competition per both Source Selection Statements. Hopefully, it will be like Dream Chaser and get a cargo mission for futher development. The Commercial Lunar Payload System (CLPS) program is for cargo delivery to the Moon, so maybe the Alpaca can get a CLPS contract or two. Forgot to mention that Alpaca was using hyrogen as well.
I wonder if the Blue Origin lander can rotate on its landing gear, or if the planned lander missions are planned to be short enough to not need reorientation to the sun while sitting on the ground near one of the poles.
If there's enough propellant, it could rise, rotate, and land again. It hardly has to rise, but I'm sure it'll be more efficient to just increase the solar panel area.
I was curious if maybe the radiators and solar panels would be rigged at the top in such a way that they can rotate - but that still wouldn't address the fact that for a week or so every month the month the sun would be blazing in directly through the windows
Assuming they actually figure out how to handle cryogenic fuels in deep space (trasport, store, transfer), I think this might be a little bit more interesting than the Starship lander which is really only interesting in that it can land rather enormous payloads (albeit several dozen meters above the surface that they then have to traverse with cables or whatnot). There are hurdles on both sides, of course, but this design, what little we can see of it, seems like it could be the more useful of the two.
@timemachine194 Really? Last I checked, the mission barely got back to NRHO with the "baseline" payload (which is the same for both). Having a high dry mass, low Isp fuel and a all-up design does that.
I like Starship for its potential, but whenever I see it pictured on the moon, I get worried about it falling over! :) Lower gravity changes the balance of forces in a landed vehicle in such a way that tall landers get somewhat more likely to fall over. It's not a huge effect, but Starship is very tall for a lander. It might be better if it had landing legs in the style of the Falcon 9. As pictured, I think it'll need active landing gear to have any chance of staying upright, though I am, of course, making assumptions about the center of mass. Perhaps there will be a lot of propellant low down.
With the recent delivery record for Boeing and Blue Origin, what do you think is the probability the lander will reach the moon with a manned mission before 2030? 2035v 2040? 😬
Give it 10 year. Maybe 15 now that Boeing is here. You know Blue Origin is no good either and they plan to launch it in New Glen rocket so give it another 3 years.
@@_mikolaj_ how does that make any sense. Starship already flown and Blue origin lander and the rocket to transport it doesn't even exist yet. And considering Blue origin and Boeing recent reputation on accomplishing their time goal BE-4 engine and Starliner..
@@LeftOverMacNCheese beacuse BO has made a lot more progress in developing New Glenn, and many of Lunar lander elements, than spacex has with starship. Sure spacex did launch an outdated abomination to catch investors, but imo it just shows how immature starship program is at the moment.
Scott: A serious question here. Does your mockup include the ability to pivot the engines well away from the vertical, in order to direct dust and debris away from the vehicle on landing? And do you think BO has the design freedom to do this? This is one thing I loved about the Dynetics lander, that it had a better solution to this problem.
@@221b-l3t Did you catch the interview with Dynetics done by Angry Astronaut about a year or so back? It went thoroughly into this. Basically, their original bid was based on what could be done within a short time frame. They also said that the design would be considerably improved - to the point of being able to start from Earth orbit, land on the moon, return to lunar orbit and then refuel. In any case, my question to Scott had more to do with whether the BO lander might be able to angle the thrust well away from the vertical - which is going to be necessary given the nozzles are so close to the surface. I'm not sure a kerbal mockup has that freedom of design.
Scott, now that Spacex has developed raptor 3, could they put 6 sea-level and 3 vacuum engines on a starship and go SSTO or just slightly sub-orbital to Hawaii.
I think SpaceX wants to test as much of the whole system (Super Heavy & Starship) as possible. I wouldn’t be surprised if SpaceX went all the way to orbit on this next one and brought it down after 3 orbits a la John Glenn in 1962…
@@TraditionalAnglican I suspect they'll stay with their original flight plan until they succeed at it. No point in adding yet another problem by trying for full orbits.
Ok I love this lander! Mainly because it will be testing some Ideas I've had forever mainly liquid hydrogen everything all the time! So I'm excited to see how this devlops!
Potential problem - that docking port is going to get pelted with lunar regolith on landing and take-off. Docking adaptors are extremely finicky things that can be made to malfunction if foreign debris gets in the mechanisms, or gets stuck between the two docking rings as they interface. This might be easily fixed though. Just put a protective cover over the docking port when its not in use, a bit like the Crew Dragon's nose cone.
@@TheEvilmooseofdoom Yes, but some of the rocks will bounce off each other or the ground and go off in unexpected directions. (Look at the papers on the weird plume shapes from the DART impact, for example. Also consider why an upright pressurized bottle can jump upward from a solid surface when its lid is opened.) Also, a small portion of the expanding gas will expand upward, even if most of it goes sideways, and carry a few rocks that way.
I actually thought it had engines at the top and the radiators were shields protecting the craft from the plume. The top makes more sense in terms of not digging a crater.
In HLS Option A, the Alpaca was too heavy to fly. In Appendix P, it had more problems than the Blue Moon lander. NASA really likes the low-slung Alpaca, so if they had been closer in development, NASA may have picked Alpaca instead. Maybe Dynetics can pick up one or more CLPS contracts for delivering cargo to the Moon.
@@steveaustin2686 Well considering New Glenn has not even launched, I fail to see how they can have something ready before SpaceX, I thought SLS or some other rocket would initially be launching their lander initially anyway.
@@nzoomed NASA wanted 2 landers for the HLS Option A contract, but the 2020 Congress gave NASA ~1/4 the funding. Otherwise, if NASA had got the HLS Option A funding that they wanted, the Blue Origin ILV would already be the second lander. This Appendix P competition was NASA getting the second lander that they wanted in the first place. SpaceX was the top bid in HLS Option A, so they are doing the Artemis III landing and the Artemis IV landing under the HLS Option B contact. The Appendix P contract for Blue is for the Artemis V mission. So hopefully SpaceX will have flown the HLS Starship 3 times to the Moon before Blue has to fly their lander twice. Both Blue and Dynetics were going to use the Vulcan Centaur for HLS Option A, as it was supposed to be flying this year anyway. Both of those HLS Option A landers would have multiple launches to get the landers to the Moon. The Vulcan Centaur is 5.4m in diameter and the new Blue Moon lander is almost 7m, so Vulcan Centaur may not have a fairing for it. The New Glenn is 7m in diameter, so it is planned to fly their lander. NG is supposed to fly in 2024 and if it does, it should be ready in time for Artemis V in 2029. The NASA IG is expecting the Artemis III mission to slide into at least 2026 and Artemis IV to slide out of 2028, so Artemis V could slide as well.
Great video! Could you make a video addressing SpaceX's HLS apparent stability upon landing? It looks as if it'll fall over if just one landing leg finds a soft spot in the Lunar surface. Soft surface + high center of gravity doesn't bode well.
I don't imagine the moon's surface would have enough variation that one leg would sink substantially more than others, but it looks like there are some quite large "feet" on each leg that would distribute the load. They already need to make the legs extend/retract to be stowed for launch, so I would expect that they'd just use the same mechanism to adjust each leg to keep the rocket level upon landing.
@@agerrgerra1361 It isn't just a matter of sinking, but also of slopes. If I recall correctly, if it landed at a similarly tilted slope as one of the Apollo landings, it would tip over
Someone at Blue Origin scratching his/her head. "Damn, we only provided an artist impression and this Scottish guy reverse engineered all our specs!" 😊 Or: "we can't work out the numbers". "Just do a press release with a pretty looking lander and Scott will do the math for us" 😉
EOR (Earth Orbit Rendezvous) was one of the methods considered for Apollo (including mating several parts and refuelling) - the SM engine is the size it is, I understand, because it had to be capable of landing and taking off from the moon. Only very late, after being shown how much less fuel LOR needed, did they consider that and ultimately switched to the separate lander unit and a single rocket to launch it all in one. So refuelling in space is not exactly a radical idea nowadays.
Well, its all nice, but first I would like BO to become a space company, that is launch something to orbit. Anything! I feel at their rate they will land on the Moon sometime after 2050.
Good to see that NASA is not 100% reliant on Starship's success, bad position to be in considering the track record of their founder with overpromising/underperforming.
@@dennyoconnor8680 Are you seriously not aware the ULA, NASA and Roskosmos exist? Musk is not special because SpaceX can get to low earth orbit. He is "special" because he is the only guy who promised he would get to mars by 2022 and land humans on mars by 2024 (in 4 Starships!). He also promised to fly around the moon by 2018. So far, he had 1 test, which exploded before it made it to orbit while losing 8+ engines in flight. He will be lucky to get another test this year. Things are not looking good. Oh, and he was also supposed to get robo-taxis working by 2018, because self driving is a "solved problem". And solar roofs, and hyperloop tunnels, and Twitter "everything app".. I don't know, he makes up so much shit, it's kind of hard to keep track. So, to summarize: Elon has a well documented history of overpromising and then failing to deliver. This is a fact.
I always felt like it was ridiculous for NASA to choose only SpaceX. Even leaving behind the fact that they had planned to choose two companies, their decision basically made the Artemis Program dependent on Starship, which (while a very promising piece of technology) was (and still is) by no means guaranteed to be viable within the timeframe that Artemis is shooting for. Having multiple potential lunar lander systems seemed like a great idea. Not putting all the eggs on one basket, so to speak
Originally NASA didn’t have the money to select two concepts for the lander. Then afterwards the money was added back in and NASA was forced to award another contract. But NASA is still cash strapped, so who knows if they’ll actually able to afford two landers.
@@Hibbidyhai It's my understanding that the Artemis missions through Artemis V are funded by Congress. So HLS Starship does 2 and Blue Moon does 1. Further Artemis missions from Artemis VI onward, have to be funded. IF China decides to not go to the Moon, I can see Congress pulling funding. IF China is going to the Moon, I don't see Congress not making sure Artemis is there too. Especially since Artemis is a multi-national program, so cutting Artemis loses face for America. Not something some in DC would care about though.
@@TheEvilmooseofdoom Blue has hardware in development. Some of which is not as far as long as NASA would have liked for Artemis III under HLS Option A. With the Appendix P contract for Artemis V, that may slide further than NET 2029 with Artemis III and iV expected to be delayed, Blue has some time to work things out. Bezos said that he wanted to speed up Blue Origin development, so this will be the time to show that, if he can.
As with everything space related the challenge will be figuring out how to make it lightweight and dependable. Hopefully the things they learn in the process will benefit Earth based systems as has happened many times in the past with space related technology.
to add to what Scott said, solid core nuclear reactors can't generate as high temperature as chemical reactions can, so in order to achieve higher efficiency they need the lightest exhaust particles possible, which is molecular hydrogen. chemical rockets' lightest exhaust particle is water molecules, which is why hydrogen-oxygen is the theoretically most efficient propellent
I'm all for reusable landers to help cut cost. My one main issue with it, though, is maintenance. From my understanding, SpaceX's rockets require a fair bit of servicing between each launch. With this lander, are they going to have to service the rockets while in orbit in between each attempt? Has anyone ever done servicing on a rocket engine and associated machinery in space before?
the forces and stresses involved with moon landing/takeoff are not comparable to a vehicle taking off from Earth. This will lessen maintenance needs a lot
I think you're talking about the Falcon 9 which uses RP-1 that burns a lot dirtier than methane. Though, I don't know all the details of turning a falcon 9 booster around between launches.
I agree with your point, I think while it's the ultimate goal to have reusable landers it's just too big of a challenge right now. A big part of reusability is inspections, as well as of course maintenance. Doing that in space is currently nearly impossible, as it requires developing a lot of capabilities that are still in their infancy. Things like the Hubble servicing missions were a training ground and many more will be needed before they can land a Starship on the Moon, launch it back to lunar orbit, refuel it, then safely land it again with crew. For now they will likely be used only once. Although I can see them eventually landing them for a second time uncrewed to provide extra storage or habitation space for a lunar base. In other words a particular Starship would land at a lunar base with crew, then launch back to lunar orbit with the same or a different crew, then land back at the base uncrewed to be used for other purposes. Inspecting the vehicle while in lunar orbit won't be as critical since the second landing would be without crew. Reusable cargo landers will likely come first, although I suspect the early versions of cargo landers will also be expendable, they will just land with their cargo and remain on the lunar surface. Eventually they are going to have quite a rocket garden on the Moon!
Part of the issue I always see for people that are hyper analytical is they can’t understand how to dream and that’s where simulation comes in very handy. You should practice more times and simulation because if you’re just looking at objective outcomes, you can believe that you’ve predicted the correct one however, in actuality, you’ve just been paying attention to specific outcomes over and over and over rather than testing possible scenarios. In other words dreams that’s why video games like Körbel Two can really come in handy for you!
It was mainly about the number and size of refueling flights. This thing needs only about 2 refuels per mission (so a total of 3 flights, same as their ILV) - the SpaceX one needs 16 of them, on a superheavy launch vehicle to boot.
Yeah and Dynetics fixed the problems they got dinged for in the first one and have a more mature design now with tested methane engines and methane rcs
This lander looks *great!* I'm very surprised that no-one came up with a lander like this *sooner* (apart from the Apollo missions!). It's more streamlined than the Apollo landers but it definitely has a bit of Apollo in its looks - the landing-legs give it that look. Best of luck to Blue Origin as they work towards getting this on the Moon!
Dynetics already had this concept a few years ago and threw it out in favor of alpaca. Those people then were scouted and blue pulled them and surprise suprise blue has the same layout as the Dynetics tiger team design
Doesn't the synchronous orbit of the moon mean that, landing on the poles, the ship will always have a different side facing the sun? Thus negating the effect of placing windows on 1 side and solar panels on the other?
I hope the New Glenn ship launch pad isnt too close to Starship Raptor 3.0 (kidding). This vehicle would be incinerated in 2 seconds. If Starship can easily takeoff and land on the moon, this lander will look like the LEM by comparison. As Chris Simms says “size is a skill”. I guess we will end up with whichever option can “FLY SAFE”! Thanks for your consistently great work Scott.
When I originally heard they won, I was disappointed. However, I wasn't aware that the design was different from the original one. The original design was terrible sense it wasn't reusable. And the ladder. This design seems to be a big improvement. Hopefully they move quicker than blue orgin and Boeing have with there rockets and capsules however. To many of there products are years behind schedule. Admittedly SpaceX may take a while on there's as well but it's capabilities are asking the moon 🌙 of a lander. Pun intended.
@originalmin If I remember correctly, it's planned for at least two missions. The starship lander should be reusable for multiple missions in theory only requiring refueling. If full reusablity isn't in the cards for any of these missions eventually funding will be cut and will end up like Apollo.
Hi Scott, 3 engines for a lander do not provide redundancy. Four might do the trick, but 3 could never be balanced on the center of mass in case of one engine failure.
It's still fine. You can land. Might be a bit tricky but offset thrust is nothing new. You would just come in at an angle, kinda like an aircraft in heavy cross wind, straighten out as the wheels/landing legs touch. Plus you can always shut the engine a second or two early and use RCS on the way down to land upright. It's the moon a few seconds won't accelerate it that much. But yeah, Space Shuttle had a super duper offset thrust vector. The center of mass was in the ET just around where the tank and orbiter connect. It's why the engine are offset so much. They fire through the center of mass of the stack, not the Shuttle itself. Similarly with 1/3 out you'd have them angled a little. Starship sometimes lands with 2/3 engines to. I believe SN15 landed on two engines and they tried some on one.
@@221b-l3t no you couldn’t you would just crash and burn because the thrust vector wouldn’t go through your cg inducing a spin and making it completely uncontrollable.
Blue engine 4 is 60% trust configuration of high trust architecture . Which probably means soon after collecting all flight data after few first launches BO will fix all bugs that could slip into design and safely crank up cargo capacity of NG from 45 tonnes to 70+ tonnes . Potentially replacing SLS in Artemis programm .
Increasing trust by 40% do not mean increase payload by 40% Yes this would inproove paylaod but but not more than a few % (To get this result they need to increse trust and propelent )
@@_mikolaj_ More efficient in terms of ISp, but that doesn't necessarily translate into a more efficient overall system... hydrogen tends to require greater structural mass, negating some of the gains from having that higher ISp.
@@simongeard4824 generally, Isp boost outweighs worse mass fraction though, plus, the bigger your system is the lesser of a problem mass fraction will be. Id say the bigger "issue" is propulsion. You need vastly more powerful pumps to keep high massflow, and hydrogen burns really hot
@@_mikolaj_ More powerful pumps... that sounds heavy. But you get the point... the efficiency of the fuel is only part of the equation, and optimising for Isp means making compromises that will have losses as well as wins.
I just hope the annual funding levels are enough that all the technolgy and hardware can be developed in a relatively short period of time. I don't want this to become another SLS or commercial crew project that takes 10 plus years. If that happens we'll be watching the Chinese building a Moon base before we get back to the Moon.

The way I look at it maybe the money could go to better purposes, but it could also go to far worse purposes.
Artemis 1 tested all sorts of things.
I agree. Orbital refueling of cryogenic fuels and oxidizer is going to be huge. Plus, the more we learn about how to utilize resources that don't come directly from Earth, the better.

We have a valid reason to return to the Moon to stay. The ice in the polar craters is supposed to be an archive of Earths climate and life, that reaches eons further back, than anything down here. There even can be samples of the proto life.
I've been making landers in KSP like this for a while because not only is it easier for landing and egress, but I often make the command pod into a dettachable rover. This way I can take a large rover all the way to the mun or duna and bring it all the way back to Kerbin with tons of science and recovering the expensive rover components.
We are going to the mun again. The what ?. The satellite orbiting earth. Ahhh the moon ?.
Yes the Mun 😂
Honestly, I don't see the appeal of bringing back a rover. There's plenty of vehicles on Earth, and they're cheap to build here (or on Kerbin). Better to leave the rover where you can use it again, even if you need to have a small ferry mission to move it to the new site.
Haha this is brilliant. I used to just make a huge tanked lander for biome hopping. But a rover command pod can reduce hopping by a lot if you keep landing on biome borders.
@@absalomdraconis It's not about bringing back a rover. It's about saving on mass by converting the command pod in to a rover. I do see the appeal of leaving behind equipment. Even if you don't use it. You can always recycle it for resources on a future colony.
@@absalomdraconis Why build anything in ksp? Sure there are other mission architectures with their own respective benefits. But why reutrn the rover? First of all, because it's fun, it's just fun to add the additional constraint that the mission must be fully reusable. Second of all, because in carreer mode sometimes the price of those science parts adds up on the rocket, so you can save money by bringing them back.
While I like the Starship, I am glad that there will be two teams working on solving the key problems that the Artemis mission profile calls for, namely refueling in orbit.
Expect the national team won't be flying anytime soon in the next 10 years. That just how it is
Also if one fails hopefully the other won't and Starship in 2023 comes off more as an uncrewed cargo transport/ base builder while this design is more crewed lander/ short term habtat.

Haven't gotten through the video yet, but Blue's new design really makes me wonder what they were thinking with the first one. With this they've shown they're clearly capable of coming up with a decent modern design, so what was with the previous Apollo-but-worse design?!!?!
The first one was a cash grab.
This is trying to justify the existence of New Glenn.
Once starship is operating there’s not going to be a good reason to use New Glenn for normal rocket launches so they need a specific application it exists for.
This gives them the breathing room required to build an actual starship competitor.
If you see the first design was very similar to Apollo landers...It's logical Northrop Grumman was on board at the time...they were really good designing the Apollo landers...but this time NG is not on board....maybe this design is more risky but probably it works better

@@absalomdraconis No, but in the absence of anyone paying for it, it doesn't have much future...
Why? No seriously, why? The design was half done and already had a negative payload mass fraction. Meaning it can deliver no payload to the moon. I mean it can but it can't get back into orbit. The fuel tanks would run dry on ascent.
So why are you a fan of a lunar lander that failed the MOST BASIC requirement of making it to the moon and back.
ALPACA was a PP presentation. Not even functional on paper. Even the Russians paper rockets at least work in theory. You and I could do better than handing in a failed project. "Hi, so I had no idea, this is my homework, I'd like a failing grade please".
Oh and ridiculously overpriced. 6 billion for the engine to run dry half way to orbit. Then an awkward 10 minutes or so, while the astronauts fall back to the moon.
Ah yes, what a design. It's actually the cheapest. It costs nothing and we're not going back. Artemis is cancelled. The money will go towards SLS, which will not be cancelled. It will become the new ISS access. The full upper stages will be left in orbit for future use.
@@221b-l3t all of this was fixed in the appendix p submission. Same capabilities as the blue design with a lower project cost and com. Equipment which actually meets the requirements and a schedule which doesn’t have “multiple contradictions”
Thanks for this. My heart sank when I heard the National Team had been selected, because their last effort was so dodgy. This seems a much better concept.
I am still utterly convinced that between Boeing and Blue Origin the chances of this flying, or being able to deliver the goods promised, within a reasonable timeframe or budget are slim to none.

Good thing its fixed firm price rather than cost plus.

@@land_and_air1250 The alpaca was not as good as this design. It is ok to be honest. A few posts have mentioned that BO needed this deal, so bezos likely funded a few billion on top of the government's price. A design with a bunch more money should be better. It sucks for dynetics, but the best design still has to win.
It will end up being like commercial crew. Without SpaceX we would still be flying on Soyuz today.

Hopefully the fixed price contract will motivate management to get things done instead of just scheduling preliminary design meeting and BS all day for decades.
Well that worked with Starliner... oh wait... Seriously though between Boeing and Blue Origin, this thing will cost three times what they bid and will not be ready 16 years from now. Bezos will have to sell some stock to cover the losses.
Thank you for including peripheral engines. I was in a distinct minority on this on some forums. Yes, I think the bulges we see are partially buried engine nozzles. There's even a hint of hoops on them.
I'm wondering if they'll be canted outward slightly to reduce the area of plume that hits directly below the lander - to reduce the amount of regolith kick up.
Exactly like the original STARSHIP submission.
If they are peripheral engines and canted out, then could they be placed further up near where the fuel tanks are located or would this make it hard to fit in the fairing. This is what people thought the original Starship illustration was doing. Maybe Blue will change the design again and put the tanks and engines on the side like the Alpaca. They could have two Blue Moon cargo versions connect to the sides of a Blue Moon crew version to make a single lander.
@@mannyalejo772 That's exactly what I was thinking they might do. This is an early render. Having the landing rockets up higher near the fuel tanks makes all kinds of sense: less intrusion into the crew cabin below, less excavation of regolith upon landing. For a 45 to 60-ton lander, exhaust excavation will probably become a serious issue (unlike the lighter landers that can just plop down on top of their engine bells)
I only wish jeff would show what’s going on at blue origin or at least post an update every once in a while. Just imagine so many more young people getting hooked to spaceflight
or to point out possible design errors.
Reminds me of a concept lander I thought of with a torus habitat around a center engine with the propellant above. The propellant would act a shielding while on the surface. The engine hidden up inside would allow for a lower profile and being more compact and having a lower center of gravity in my design. Then at that less outward structure of landing legs would be needed. All contribute to making a lighter craft.
Although my faith in BO isn't super high, I'm really hoping they'll be able to see this through all the way to the moon and back.
Even if they fall short, it's good to have some competition for SpaceX. And the insights & experience engineers will get with hydrogen will be incredibly valuable in the coming decade on earth as well, considering it has some role to play in energy transition plans of many countries.
With all the hydrogen leaks on SLS when on the pad with many available engineers with torque wrenches, it'll be interesting to see how that works on an automated system...
In space!
So far NASA have managed to demonstrate keeping cryogenic methane cooled on the ISS...for four months until the chiller broke. (Which meant they couldn't test actually transferring it between tanks.)
So, keeping hydrogen chilled is probably doable, but it's going to take a few more years of testing before there's any useable hardware I think.
Interesting is one word for it...
@@phuzz00 Keeping it cool is only the first of a long list of problems H2 presents.
specially when they can't fix them.
Originally, Blue complained about Starship needing on-orbit refueling and a massive elevator. I feel like once they got the chance to redesign for take two, they decided that refueling was doable, even with hydrogen, but that the elevator could never be made to work.
They needed complementary advantage, since they lost the "one" competition; stealing from ALPACA's playbook was quite natural.
And, of course, it's to their merit that they learned from their mistakes, instead of just pushing the lobbying fan into overdrive.
@@timemachine1944 Nothing is simple tech when required to work flawlessly on the moon far away from help. It adds an extra mission critical component of moving parts that can break down and render the mission impossible to complete. Elevators on earth break down all the time!

Doesn't even need electricity for the last backup.
@@neniAAinen they instead chose to lobby in the proposal by bidding a price to NASA that they admit is half of the cost that it’s going to cost blue undercutting Dynetics who’s lander was cheaper in total cost but more expensive to NASA as they don’t have bezos bucks
@timemachine194 The elevator itself works fine once you've added redundancies with backup motors and whatnot, it's just that all that weight for the winch and basket to carry the crew is mass that can't be used to carry payload to the lunar surface. All that extra mass needs fuel to get it to the lunar surface and then back up into orbit to rendezvous with Orion, so that means there's that much less science payload that can be returned because you have to schlep the elevator back up with you. It's not a technology thing, it's a mass thing. Blue Origin solves that problem by putting the crew at the surface and eliminates the elevator altogether.
In Kerbal 1 this is how I generally did landers, with the descent engine and fuel tank above the crew and with small engines on the side at an angle. So that way you could ditch it on the surface and have a much lighter ascent stage, without having the crew way high up off the ground. (More stable, too)
I always wanted to do this, but didn't because I assumed it wasn't realistic - otherwise why didn't they try it in real life. I guess I assumed wrong!
Those tanks look thoroidal to me. This leads me to think that there is a docking hatch also on top and a crew transfer tunnel in the middle.
If there's anything we've learned about crew safety, it is that it is better to put people on top of propellent than anywhere else.
There is an Airbus concept drawing of a new airplane with liquid hydrogen tanks over the passenger cabin. All I could think of is, go screw yourself, Airbus. And I've never flown.

Thanks for giving us a sneak peak at what it might be like. My favorite part is when the astronaut popped out on the lunar surface. Lots to do before any of our latest and greatest get to the moon!
even funnier when you realize it looks like a Bart Simpson.
Can't wait to see how close you got it Scott!!
Those strange things you refer to as radiators strike me as deflectors if the engines were positioned in the slots at the top of them. This would have the Starship HLS's advantage of keeping the concentrated exhaust plume away from the surface.
Very interesting possibility! I hope you're right. Exhaust excavation will probably be a problem with such a massive lander. Unless they clear and sinter a landing pad ahead of time...
one big advantage this has in the long term over starship and alpaca (both use methane) is that hydrogen can eventually be produced on the surface and then no refueling in space has to be done (if they manage to store it long enough between landings) because they can refuel enough for an ascent and another landing just on the surface alone. also it might be useable as a hydrogen transport system for a nuclear powered ship that is constucted unfueled in lunar orbit, even more if down the road they make a version that replaces the crew cabin with another hydrogen storage tank
75% of all known asteroids are carbonaceous, so I'm wondering if they might find carbon under the Moon's surface, and might be able to synthesize methane from carbon and hydrogen. Perhaps not though. The carbonaceous asteroids are clustered toward the outer edge of the main belt where the sun's heat doesn't affect them too much.

Well done Sir, facts and details as usual. Thank you Dr. Manley.
Much improved lander than previously proposed, but concerning about LH transfer. Good luck.
Thanks Scott for keeping up with all of this no matter what is decided it is an exciting time we live in.
If you have multiple engines for redundancy, you probably want them close to the center. You want to be able to fire just two without creating a large moment.
And the solution is to angle them the right way. Look at the angle of the Space Shuttle Main Engines … they are not along the shuttle , but point roughly through the combined shuttle/fuel tank centre of mass, which means no angular momentum. That is also how you make a single booster for a rocket work.
feels like they for the first time thought a bit about the design instead of just putting 3 different legosets on top of each other and calling it done. much better than the previous one. maybe even the best design so far for this mission.
You mention a paper in the New Glenn fairing. Does it give an inside diameter, the usable payload space? On F9 and Atlas V this is 0.4m less than the outside diameter. I'm trying for a good figure for the crew quarters. If the legs don't fold completely underneath then it'll be be barely 6m, right? A little more otherwise.
Interesting to use the press image as the basis for a Kerbal model to guess what it might be like.
45 Tons was the propellant mass 16 tons was the dry mass making a total mass of 61 tons.
Dynetics has a total mass of 62 tons for same payload capacity as blue meaning that they gain nothing from the hydrogen and maybe less than nothing since they have a tug which provides support for delta v.
Also the Dynetics lander is also 1 fuel using methane in the rcs thrusters which they’ve already tested and using a main engine which has been tested and both work. Dynetics has engine out capability as well as heavy shielding to protect the crew and tanks from rocks and debris from the lunar surface and landing legs which seems absent from the blue design
@scottmanley I'd be very interested in your take on the "it's tall and tilty" arguments being bandied around for both the Blue Origin and SpaceX proposals.
Is there anyplace around the lunar south pole that is as flat as the landing site depicted in your KSP animation?
I'm sure that mod is based on the best data available, but also they might want to keep the poly count from getting too high. So I'd answer your question with "probably, but not definitely."

Europe ... Let's not talk about it.
So Boeing and Blue Origin. Is this likley to fly before 2040?
Hydrogen is difficult enough as it is to handle on Earth, let alone in orbit or on the Moon. But at least they've sorted out the ludicrously long ladder. To me, the Alpaca seemed to be the ideal solution, ticked all the boxes. It probably came down to which design would give jobs to enough people in sufficient states.
While I like Alpaca and NASA evidently loves the low-slung Alpaca design, Dynetics has apparently had a lot of problems making it work. It was too heavy to fly in the HLS Option A competition and had more problems than Blue Moon in the Appendix P competition per both Source Selection Statements. Hopefully, it will be like Dream Chaser and get a cargo mission for futher development. The Commercial Lunar Payload System (CLPS) program is for cargo delivery to the Moon, so maybe the Alpaca can get a CLPS contract or two.
Forgot to mention that Alpaca was using hyrogen as well.
I think it’s exciting no matter how you look at it. It’s going to be a long, hard road because this time, we’re going back to stay.
I wonder if the Blue Origin lander can rotate on its landing gear, or if the planned lander missions are planned to be short enough to not need reorientation to the sun while sitting on the ground near one of the poles.
That's my first thought, too. The moon rotates once a month and the first missions are to the south pole.
It cannot
If there's enough propellant, it could rise, rotate, and land again. It hardly has to rise, but I'm sure it'll be more efficient to just increase the solar panel area.
I was curious if maybe the radiators and solar panels would be rigged at the top in such a way that they can rotate - but that still wouldn't address the fact that for a week or so every month the month the sun would be blazing in directly through the windows
@@minikawildflower The windows have shields, similar to those on the ISS.
You called it. Blue Moon's been officially verified as having 3 BE-7s.
Assuming they actually figure out how to handle cryogenic fuels in deep space (trasport, store, transfer), I think this might be a little bit more interesting than the Starship lander which is really only interesting in that it can land rather enormous payloads (albeit several dozen meters above the surface that they then have to traverse with cables or whatnot). There are hurdles on both sides, of course, but this design, what little we can see of it, seems like it could be the more useful of the two.
@timemachine194 The most important metric is cost per mission.
@timemachine194 Really? Last I checked, the mission barely got back to NRHO with the "baseline" payload (which is the same for both). Having a high dry mass, low Isp fuel and a all-up design does that.
@timemachine194 Well, the HLS concept mission, to be precise. Numerical analysis of it.
I like Starship for its potential, but whenever I see it pictured on the moon, I get worried about it falling over! :) Lower gravity changes the balance of forces in a landed vehicle in such a way that tall landers get somewhat more likely to fall over. It's not a huge effect, but Starship is very tall for a lander. It might be better if it had landing legs in the style of the Falcon 9. As pictured, I think it'll need active landing gear to have any chance of staying upright, though I am, of course, making assumptions about the center of mass. Perhaps there will be a lot of propellant low down.
@timemachine194 Misleading indeed, yes! :)
Scott, have you ever done on a video on the reaction engines design, and pre cooler. That's a efficient bit of kit for chilling.
With the recent delivery record for Boeing and Blue Origin, what do you think is the probability the lander will reach the moon with a manned mission before 2030? 2035v 2040? 😬

They also said that the design would be considerably improved - to the point of being able to start from Earth orbit, land on the moon, return to lunar orbit and then refuel. In any case, my question to Scott had more to do with whether the BO lander might be able to angle the thrust well away from the vertical - which is going to be necessary given the nozzles are so close to the surface. I'm not sure a kerbal mockup has that freedom of design.
0:19 That pressurized section looks like a back-woods Liquid Propane tank! LOL
Scott, now that Spacex has developed raptor 3, could they put 6 sea-level and 3 vacuum engines on a starship and go SSTO or just slightly sub-orbital to Hawaii.
I think SpaceX wants to test as much of the whole system (Super Heavy & Starship) as possible. I wouldn’t be surprised if SpaceX went all the way to orbit on this next one and brought it down after 3 orbits a la John Glenn in 1962…
@@TraditionalAnglican I suspect they'll stay with their original flight plan until they succeed at it. No point in adding yet another problem by trying for full orbits.
Your explanations are allways great. You a realy a gift to us spacenerds 😊. Thanx a lot!
Ok I love this lander! Mainly because it will be testing some Ideas I've had forever mainly liquid hydrogen everything all the time! So I'm excited to see how this devlops!
It's Boeing and Blue Origin. That means 12 years from now they will still be trying to launch this thing with buggy software and stuck valves.
Potential problem - that docking port is going to get pelted with lunar regolith on landing and take-off. Docking adaptors are extremely finicky things that can be made to malfunction if foreign debris gets in the mechanisms, or gets stuck between the two docking rings as they interface.
This might be easily fixed though. Just put a protective cover over the docking port when its not in use, a bit like the Crew Dragon's nose cone.
How would it get pelted? Things tend to move away from the source of pressure, not towards.
@@TheEvilmooseofdoom Yes, but some of the rocks will bounce off each other or the ground and go off in unexpected directions. (Look at the papers on the weird plume shapes from the DART impact, for example. Also consider why an upright pressurized bottle can jump upward from a solid surface when its lid is opened.) Also, a small portion of the expanding gas will expand upward, even if most of it goes sideways, and carry a few rocks that way.
I made a lander much like that once, only it had the engines at the top. Great video as always!
I actually thought it had engines at the top and the radiators were shields protecting the craft from the plume.
The top makes more sense in terms of not digging a crater.
NASA has $3.5 billion that they’ll pay for that!
@@gasdive did the Apollo missions dig craters?
@@gasdive Oh, I WAS playing KSP, btw! So take that under advisement! 😁
@@icaleinns6233 I'm beginning to suspect that there's a lot of spitballing happening in Kerbal these days. Like "what if we tried this?"
But why does it have a spare tire hanging off the side? Is it a Jeep? 🤔
The dynetics lander still looked like a better option to me. This thing just looks top heavy.
In HLS Option A, the Alpaca was too heavy to fly. In Appendix P, it had more problems than the Blue Moon lander. NASA really likes the low-slung Alpaca, so if they had been closer in development, NASA may have picked Alpaca instead. Maybe Dynetics can pick up one or more CLPS contracts for delivering cargo to the Moon.
@@steveaustin2686 Well considering New Glenn has not even launched, I fail to see how they can have something ready before SpaceX, I thought SLS or some other rocket would initially be launching their lander initially anyway.
@@nzoomed NASA wanted 2 landers for the HLS Option A contract, but the 2020 Congress gave NASA ~1/4 the funding. Otherwise, if NASA had got the HLS Option A funding that they wanted, the Blue Origin ILV would already be the second lander. This Appendix P competition was NASA getting the second lander that they wanted in the first place.
SpaceX was the top bid in HLS Option A, so they are doing the Artemis III landing and the Artemis IV landing under the HLS Option B contact. The Appendix P contract for Blue is for the Artemis V mission. So hopefully SpaceX will have flown the HLS Starship 3 times to the Moon before Blue has to fly their lander twice.
Both Blue and Dynetics were going to use the Vulcan Centaur for HLS Option A, as it was supposed to be flying this year anyway. Both of those HLS Option A landers would have multiple launches to get the landers to the Moon.
The Vulcan Centaur is 5.4m in diameter and the new Blue Moon lander is almost 7m, so Vulcan Centaur may not have a fairing for it. The New Glenn is 7m in diameter, so it is planned to fly their lander. NG is supposed to fly in 2024 and if it does, it should be ready in time for Artemis V in 2029.
The NASA IG is expecting the Artemis III mission to slide into at least 2026 and Artemis IV to slide out of 2028, so Artemis V could slide as well.
Multiple launches on rockets that didn't fly yet, in-orbit refueling, reusable lander ? Sounds massively complex and high risk
Great video! Could you make a video addressing SpaceX's HLS apparent stability upon landing? It looks as if it'll fall over if just one landing leg finds a soft spot in the Lunar surface. Soft surface + high center of gravity doesn't bode well.
I think Spacex will sweep the landing site with a starship touch and land the real starship after the dust has settled.
I don't imagine the moon's surface would have enough variation that one leg would sink substantially more than others, but it looks like there are some quite large "feet" on each leg that would distribute the load. They already need to make the legs extend/retract to be stowed for launch, so I would expect that they'd just use the same mechanism to adjust each leg to keep the rocket level upon landing.
Why would it fall over? SX SS is bottom heavy. This BO lander looks way more difficult to balance.
@@agerrgerra1361 It isn't just a matter of sinking, but also of slopes. If I recall correctly, if it landed at a similarly tilted slope as one of the Apollo landings, it would tip over
as shown by multiple impacts of landers and probes, the surface of the moon is not soft after all, it is mostly bassalt.
What does Kerbel say about Thunderbird 3, given that you have the head to body ratio just sbout right for the astronauts?!
Stil like the Dynetics design the best ...
Hi Scott. Thx4up, I hope you're fine.
Someone at Blue Origin scratching his/her head. "Damn, we only provided an artist impression and this Scottish guy reverse engineered all our specs!" 😊
Or: "we can't work out the numbers". "Just do a press release with a pretty looking lander and Scott will do the math for us" 😉
Nice to see the lander design I used in KSP 1 becoming reality.
Space gas station food is really going to suck.
The upside is that a case of the worms can make you a better person.
You're not looking forward to space nachos??
To me, this is a much more elegant design for a lander than Starship.
Godspeed, Default Name-2.
2:14 that made me chuckle
EOR (Earth Orbit Rendezvous) was one of the methods considered for Apollo (including mating several parts and refuelling) - the SM engine is the size it is, I understand, because it had to be capable of landing and taking off from the moon.
Only very late, after being shown how much less fuel LOR needed, did they consider that and ultimately switched to the separate lander unit and a single rocket to launch it all in one.
So refuelling in space is not exactly a radical idea nowadays.
Well, its all nice, but first I would like BO to become a space company, that is launch something to orbit. Anything! I feel at their rate they will land on the Moon sometime after 2050.
Good to see that NASA is not 100% reliant on Starship's success, bad position to be in considering the track record of their founder with overpromising/underperforming.
Says you about the only guy in the game who is up to orbit and back, currently. Three trips on one long weekend just ended.
@@dennyoconnor8680 Are you seriously not aware the ULA, NASA and Roskosmos exist?
Musk is not special because SpaceX can get to low earth orbit. He is "special" because he is the only guy who promised he would get to mars by 2022 and land humans on mars by 2024 (in 4 Starships!). He also promised to fly around the moon by 2018. So far, he had 1 test, which exploded before it made it to orbit while losing 8+ engines in flight. He will be lucky to get another test this year. Things are not looking good.
Oh, and he was also supposed to get robo-taxis working by 2018, because self driving is a "solved problem". And solar roofs, and hyperloop tunnels, and Twitter "everything app".. I don't know, he makes up so much shit, it's kind of hard to keep track.
So, to summarize: Elon has a well documented history of overpromising and then failing to deliver. This is a fact.
I always felt like it was ridiculous for NASA to choose only SpaceX. Even leaving behind the fact that they had planned to choose two companies, their decision basically made the Artemis Program dependent on Starship, which (while a very promising piece of technology) was (and still is) by no means guaranteed to be viable within the timeframe that Artemis is shooting for. Having multiple potential lunar lander systems seemed like a great idea. Not putting all the eggs on one basket, so to speak
Originally NASA didn’t have the money to select two concepts for the lander. Then afterwards the money was added back in and NASA was forced to award another contract. But NASA is still cash strapped, so who knows if they’ll actually able to afford two landers.
At least spacex has hardware under actual development. How much of the BO proposal is starting from scratch?
@@Hibbidyhai It's my understanding that the Artemis missions through Artemis V are funded by Congress. So HLS Starship does 2 and Blue Moon does 1. Further Artemis missions from Artemis VI onward, have to be funded. IF China decides to not go to the Moon, I can see Congress pulling funding. IF China is going to the Moon, I don't see Congress not making sure Artemis is there too. Especially since Artemis is a multi-national program, so cutting Artemis loses face for America. Not something some in DC would care about though.
@@TheEvilmooseofdoom Blue has hardware in development. Some of which is not as far as long as NASA would have liked for Artemis III under HLS Option A. With the Appendix P contract for Artemis V, that may slide further than NET 2029 with Artemis III and iV expected to be delayed, Blue has some time to work things out. Bezos said that he wanted to speed up Blue Origin development, so this will be the time to show that, if he can.
They didn't want to only select SpaceX. just that there was no MONEY available for anything else.
Refrigerators are heavy, radiators are heavy, both systems require power, seems like a big mistake.
As with everything space related the challenge will be figuring out how to make it lightweight and dependable. Hopefully the things they learn in the process will benefit Earth based systems as has happened many times in the past with space related technology.
Shouldn't Blue Origin get to LEO first ?
YOU ALMOST LOST ME AT YOUR FROOTY CAP SHUL NIGEL, BUT U WON ME BACK WITH DEETS. GOOD WORK.
So nuclear engines need hydrogen as reaction mass? I'd thought xenon etc would be better... I guess more thrust, but less specific impulse (time).
Nuclear Thermal wants hydrogen, Nuclear electric wants xenon.
to add to what Scott said, solid core nuclear reactors can't generate as high temperature as chemical reactions can, so in order to achieve higher efficiency they need the lightest exhaust particles possible, which is molecular hydrogen. chemical rockets' lightest exhaust particle is water molecules, which is why hydrogen-oxygen is the theoretically most efficient propellent
Blue orgin 's lander is cool and unique but refueling in orbit will be difficult
I'm all for reusable landers to help cut cost. My one main issue with it, though, is maintenance. From my understanding, SpaceX's rockets require a fair bit of servicing between each launch. With this lander, are they going to have to service the rockets while in orbit in between each attempt? Has anyone ever done servicing on a rocket engine and associated machinery in space before?
the forces and stresses involved with moon landing/takeoff are not comparable to a vehicle taking off from Earth. This will lessen maintenance needs a lot
@@marcogenovesi8570on the other hand, lunar dust will probably increase maintenance, due to just how destructive it can be
I think you're talking about the Falcon 9 which uses RP-1 that burns a lot dirtier than methane. Though, I don't know all the details of turning a falcon 9 booster around between launches.
I agree with your point, I think while it's the ultimate goal to have reusable landers it's just too big of a challenge right now. A big part of reusability is inspections, as well as of course maintenance. Doing that in space is currently nearly impossible, as it requires developing a lot of capabilities that are still in their infancy. Things like the Hubble servicing missions were a training ground and many more will be needed before they can land a Starship on the Moon, launch it back to lunar orbit, refuel it, then safely land it again with crew. For now they will likely be used only once.
Although I can see them eventually landing them for a second time uncrewed to provide extra storage or habitation space for a lunar base. In other words a particular Starship would land at a lunar base with crew, then launch back to lunar orbit with the same or a different crew, then land back at the base uncrewed to be used for other purposes. Inspecting the vehicle while in lunar orbit won't be as critical since the second landing would be without crew.
Reusable cargo landers will likely come first, although I suspect the early versions of cargo landers will also be expendable, they will just land with their cargo and remain on the lunar surface. Eventually they are going to have quite a rocket garden on the Moon!
@@marcogenovesi8570 IT is even less than about half what it takes for Mars.
Part of the issue I always see for people that are hyper analytical is they can’t understand how to dream and that’s where simulation comes in very handy. You should practice more times and simulation because if you’re just looking at objective outcomes, you can believe that you’ve predicted the correct one however, in actuality, you’ve just been paying attention to specific outcomes over and over and over rather than testing possible scenarios. In other words dreams that’s why video games like Körbel Two can really come in handy for you!
Hang on, wasn’t extra earth refueling one of the big arguments Blue Origin used against spacex’s bid when they threw their little tantrum?
"Immensely complex and high risk"
It was mainly about the number and size of refueling flights. This thing needs only about 2 refuels per mission (so a total of 3 flights, same as their ILV) - the SpaceX one needs 16 of them, on a superheavy launch vehicle to boot.
Idea for "That KSP doesn't teach" : Fuel transfer between modules
This design is better than the first one. Dynetics lander was cooler.
Yeah and Dynetics fixed the problems they got dinged for in the first one and have a more mature design now with tested methane engines and methane rcs
A much better concept design than the single-use 'Apollo LM on steroids with a suicide ladder' model. Great animation in Kerbal!
That concept was pretty much just their variant of the NASA "Reference" design. Did exactly what was asked of it, and nothing more.
This lander looks *great!*
I'm very surprised that no-one came up with a lander like this *sooner* (apart from the Apollo missions!).
It's more streamlined than the Apollo landers but it definitely has a bit of Apollo in its looks - the landing-legs give it that look.
Best of luck to Blue Origin as they work towards getting this on the Moon!
Funny thing is, one "Space Tug - lander derivative" concept from the 70s looks pretty much exactly alike
Dynetics already had this concept a few years ago and threw it out in favor of alpaca. Those people then were scouted and blue pulled them and surprise suprise blue has the same layout as the Dynetics tiger team design
streamlining is useless on the Moon.
Doesn't the synchronous orbit of the moon mean that, landing on the poles, the ship will always have a different side facing the sun? Thus negating the effect of placing windows on 1 side and solar panels on the other?
The sun only need not be in their face during landing and launching periods
I thought this as well. So the solar panels would only provide power half of the month as well ?
@@b1lleman yea idk maybe they rotate or something
The SpaceX lander makes the most sense since the moon is known for it's completely smooth and flat surfaces.😂
@@timemachine1944
Hey Elon. Read a history book for once. Apollo 11 almost ran out of fuel trying to avoid rocks.
I hope the New Glenn ship launch pad isnt too close to Starship Raptor 3.0 (kidding). This vehicle would be incinerated in 2 seconds. If Starship can easily takeoff and land on the moon, this lander will look like the LEM by comparison. As Chris Simms says “size is a skill”. I guess we will end up with whichever option can “FLY SAFE”! Thanks for your consistently great work Scott.
When I originally heard they won, I was disappointed. However, I wasn't aware that the design was different from the original one. The original design was terrible sense it wasn't reusable. And the ladder.
This design seems to be a big improvement. Hopefully they move quicker than blue orgin and Boeing have with there rockets and capsules however. To many of there products are years behind schedule. Admittedly SpaceX may take a while on there's as well but it's capabilities are asking the moon 🌙 of a lander. Pun intended.
*since *their *too *their *theirs *its
The starship HLS is not reusable either tho
@@originalmin And with its concept of operations, it is unlikely to be reusable on the future
@harbingerdawn and no one cares.
@originalmin If I remember correctly, it's planned for at least two missions. The starship lander should be reusable for multiple missions in theory only requiring refueling. If full reusablity isn't in the cards for any of these missions eventually funding will be cut and will end up like Apollo.
When corporate and state merge and push for one singular goal....... What is the definition of that? For some reason, the name of that escapes me.
Hi Scott, 3 engines for a lander do not provide redundancy. Four might do the trick, but 3 could never be balanced on the center of mass in case of one engine failure.
It's still fine. You can land. Might be a bit tricky but offset thrust is nothing new. You would just come in at an angle, kinda like an aircraft in heavy cross wind, straighten out as the wheels/landing legs touch. Plus you can always shut the engine a second or two early and use RCS on the way down to land upright. It's the moon a few seconds won't accelerate it that much.
But yeah, Space Shuttle had a super duper offset thrust vector. The center of mass was in the ET just around where the tank and orbiter connect. It's why the engine are offset so much. They fire through the center of mass of the stack, not the Shuttle itself. Similarly with 1/3 out you'd have them angled a little. Starship sometimes lands with 2/3 engines to. I believe SN15 landed on two engines and they tried some on one.
What about RCS? Wouldn't that be able to counteract the rotation?
@@221b-l3t no you couldn’t you would just crash and burn because the thrust vector wouldn’t go through your cg inducing a spin and making it completely uncontrollable.
wait it has to be fueld in earth orbit and moon orbit? remember when BO said starship was too complicated
Mighty tall order for a amusement ride company.
Blue engine 4 is 60% trust configuration of high trust architecture . Which probably means soon after collecting all flight data after few first launches BO will fix all bugs that could slip into design and safely crank up cargo capacity of NG from 45 tonnes to 70+ tonnes . Potentially replacing SLS in Artemis programm .
Increasing trust by 40% do not mean increase payload by 40%
Yes this would inproove paylaod but but not more than a few %
(To get this result they need to increse trust and propelent )
not enough, SpaceX has already produced engines for 150 tonnes.
Why hydrogen? Doesn’t that make it more complicated to control leaks?
theres water on the moon (H2O), so hydrogen and oxygen to mine
Aside from ISRU
Hydrogen is way more efficient, and Blue Origin has a LOT of experience in handling LH2
@@_mikolaj_ More efficient in terms of ISp, but that doesn't necessarily translate into a more efficient overall system... hydrogen tends to require greater structural mass, negating some of the gains from having that higher ISp.
@@simongeard4824 generally, Isp boost outweighs worse mass fraction though, plus, the bigger your system is the lesser of a problem mass fraction will be.
Id say the bigger "issue" is propulsion. You need vastly more powerful pumps to keep high massflow, and hydrogen burns really hot
@@_mikolaj_ More powerful pumps... that sounds heavy. But you get the point... the efficiency of the fuel is only part of the equation, and optimising for Isp means making compromises that will have losses as well as wins.
I have my reservations about the Blue Origin lander. It turns the Astronauts squat and green.
Boldly going where we've been before, but with much more complication and much less money.
Tbf, having the habitation module at the bottom would mitigate the need for a long ladder
I just hope the annual funding levels are enough that all the technolgy and hardware can be developed in a relatively short period of time. I don't want this to become another SLS or commercial crew project that takes 10 plus years. If that happens we'll be watching the Chinese building a Moon base before we get back to the Moon.
Given blue origin track record… China’s likely to beat us. Though the moon is a poor prize, it’s Mars that really matters.
Yeah, but look at the other things the Chinese government does. They have no problems letting LOTS of their people die in the name of "progress". Intelsat 708 anyone?
