Looks like it took a lot of design language from NASA's Multi-Mission Surface Exploration Vehicle (MMSEV) concept. That's a good thing, that was a great concept that NASA unfortunately had to can as part of the cancellation of the Constellation program (which only happened because of the 2008 financial crisis). The MMSEV design was also adaptable into an orbital spacecraft with removal of ground-motive systems and addition of RCS and an engine. Likely an AJ10 derived engine and hypergolic RCS would be selected, but if higher Delta-V was needed they could also have looked into taking lessons from the Centaur ACES concept and using hydrolox with long loiter time abilities instead, or even taken parts of the Constellation Lunar Lander propulsion system which was planned to use Methalox due to it being easier to store liquid methane than liquid hydrogen, while still having higher per-mass performance than Hypergolic systems.
@@lorenzojimenezgutierrez4086 It's not like it's a one-time deal, and it's not like Japan is going anywhere anytime soon (they survived 2 second sunrises, which is more than I can say about the US), so I think that mandating domestic production of it is a fantastic way to kill the program prematurely.
Getting it to look good is just a matter of adding a bunch of clip-on decorative plastic crap on top of the vehicle. But that's the thing, space flight has no weight budget for decorative crap.
@@WeirdSeagul Maybe the should donate the first booster one to retire from old age? Actually, what I'm kinda wondering if we will see is if SpaceX switches to an accelerated lifetime testing program at some point? Ship a high cycle booster to TX, build a launch and landing pad there and start doing daily/weekly hops with water tanks on top until something fails.

I think the Olson (TZ) DB needs an extension for different speeds of time now. Great, one more field to parse and understand. I had hoped to never touch my TZDB parser code again.
That Carbon Monoxide rocket idea has another advantage if it's all built into a single lander: You already have the capacity to move gases around, which enables use of said gas for things other than making more propellant for the rocket. Things such as cleaning dust and other deposited materials off the solar panels to restore power generation, if martian winds don't do that for you adequately.
@@SocialDownclimber Fast is a relative thing, you're not gonna ISRU the fuel you need to get to orbit in the ~40ish sols you have between the Earth-Mars arrival window and the nearest Mars-Earth departure window. If you want to use ISRU, you already committed to the return window after that. Besides, as far as we know the samples collected thus far, are just dumb rocks. That means that the speed of the return is absolutely not critical, which means that using ISRU to reduce the launch mass of the sample return mission's surface-to-orbit segment is a great way to reduce the size of the launcher you need. That means the sample return mission can probably get away with using a cheaper rocket for that segment. I know that's a tiny fraction of the overall costs of the whole thing, but it looks great to congress and the average layperson taxpayer so even if it takes longer and costs more overall it'll probably get funded because it spreads those costs out over MORE TIME meaning less cost per year. Plus I'm sure that you don't "need" nuclear power, you do need a lot of power but that doesn't mean you have to send a nuclear thing. Sending a nuclear thing takes a lot of setup time BEFORE launch anyways, we literally don't have enough Pu-238 to make RTG's big enough for that purpose right now, so solar panels are the way to go. They could develop some sort of larger flexible solar array (individual cells would be standard solid monocrystalline solar cells mounted on a flexible backing, similar to how the ISS replacement solar arrays are constructed) that would be rolled out over the surface by the action of springs integrated into the solar array trying to unroll it over the terrain once the latches release, that way you don't have to design some complex rigid unfolding solar array with a lot more moving parts and points of failure for the same or likely a lot less power output. And like I mentioned in my first post, if it is decided to use a carbon monoxide rocket, those solar panel arrays could have some sort of hose with regular perforations in it integrated into them to blow dust off of them if the need arises (no wind? Make your own wind to clean off those solar panels!).
I totally knew when the perseverance mission was going to end up like this sine the first announcement. They made the return mission way too complex. The rover should have carried the samples with it so one mission was guaranteed to grab the samples
Yeah, i need answers. if it is 59microsecnods per year, why bother with it you can do a correction every month and it wont matter much. If it is per day then it is a problem.
According to wikipedia (Coordinated Lunar Time article) it is per day. Losing less than a few milliseconds per day is not a problem for a computer network - PC clocks lose or gain much more all the time and the speed of the Operating system clock can be adjusted to correct for that. It is however a big problem if you want to do navigation or astronomy - both require super precise clocks. Light travels about 1770m in 59µs - this gives you an extreme deviation for GPS-like location tracking and very inaccurate speeds for doppler-based measurements.
Looking forward to IFT4. ... ... ... Wouldn't it be epic if there was a camera platform on station at the "virtual tower" location for the booster's catch descent profile and hover. Would make for a powerful PR video!
Scott! I'm wondering if you'd consider talking about the Decadal Survey in a video, with a Uranus orbiter chosen as top priority over Mars sample return. Could be an interesting opportunity also to discuss the current plutonium production pipeline problems.
You’re exactly right about stretching falcon 9. They used to have to launch payloads on heavy that they can now use a falcon 9 for. They will figure out how to stretch starship
For sample return i would go for a solid rocket design with monopropellant thrusters and a final ion engine, folded in half or in 3 parts for compactness, to avoid propellant boiloff and complexities, it would delay sample return some years but reliability would be great, solid rocket motors have proven in various designs that they reach determined orbits
What a time when the main constraint on ISS launches is parking space, like the local mall! I guess that should be a big consideration for Reef something or other and the Lunar Gateway.
NASA's new task to develop lunar-time might be quite relevant to Sabine Hossenfelder's latest video about why it's so complicated to develop accurate long-lasting clocks.
Love your channel Scott! Is their an estimate of how many satellites are currently orbiting earth and What types they are (categories) of missions they are? I find it amazing how many are put into space each week. Thanks!
Hi Scott, could you or your editor add timestamps to your UA-cam videos? Sometimes I don't have enough time to watch the entire video and just want to hear about the rovers, new suits etc. Loving the videos, keep it up
Doesn't it! Hell, as a former warehouse worker I've operated lifting machines similar to the Astrolab "Rover". Astrolabs design is a "base operations workhorse", not an exploratory vehicle. Possible future: Astrolabs "Lunar Lifter" working at base, unloading cargo, rolling along 3D printed pads, roads and aprons; Lunar Outposts "Lunar Truck with winch" building outposts and worksites further out; Intuitive Machines "Lunar Explorer" connecting all and exploring beyond; While above, GATEWAY crews monitor remote probes. Standardized equipment for specialized roles.
Probably to reduce complexity. Also the plan is that the first stage of starship is supposed to land back on the launch pad. If there were side boosters there would be no place for them to land.
Has nothing to do with Boeing Commercial Aircraft, which is where the problems are. Boeing have hundreds of programs making top-notch stuff, but the media makes money from scandalizing, so you don't hear about it. Starliner has already launched and recovered safely twice. Criticizing a development program is silly. If you need to do that, direct your bile at Starship, which is a deathtrap.
The final Delta IV launch was also the sendoff of the last of the Titan legacy hardware… the huge metal tri-sector fairing from the Titan IV that was retained for these payloads and missions when Delta IV Heavy took over that special role…
Sure, wing it is a legit strat. The mileage varies though based on where you start. On the education of your initial guesses. Sometimes you do it right with some help, sometimes get lucky and sometimes you just burn through a lot of cash and time getting there chiseling every inch.
I truly do not understand how one vehicle, essentially a high-tech car, can cost over $1 billion. It's absolute madness, if you ask me. Is it made out of diamonds or something?
Normal cars on earth are relatively cheap because they build hundreds of thousands or even millions of them and can recoup the development cost over time. If a company builds a one-off car for you it will easily cost in the millions, tens of millions if there is some critical high tech component to it. Now, the lunar vehicle has lots of critical components, its definitely one-off (or close to that), it operates in a hostile environment (imagine driving through fine sharp glass shards all the time, no roads), it has to be easily serviceable and super reliable (try finding a mechanic shop on the moon) and there is the little matter of shipping it to the customer on the moon. All of that combined easily explains a cost in the hundreds of millions, or even a billion.
I think the problem is more deciding on a standard time increment and a standardized method of translation back to Earth time increments than picking where to start counting. Its also very likely that whatever method is chosen will have to be designed with an eye on being applied or used as a basis for application on other planets, so its a pretty huge decision with far reaching impacts.
@@patreekotime4578 No, you don't need 'Moon time' to match 'Mars time'. Mars already has its own time; each sol lasts 24h 39m 35s and so far a martian calendar hasn't been necessary. The Moon is very different, with one lunar 'day' lasting a month. I should think GMT (Eastern Daylight Time, 'mission time' or whatever) should suffice for now.
@@nagualdesign Im not sure you understood the problem. This isnt about "lunar days" or "martian days". It's about relativity causing clocks to count differently on different celestial bodies. To work around the relatavistic problems you absolutely have to have a different way of counting time or converting it.

That means the sample return mission can probably get away with using a cheaper rocket for that segment. I know that's a tiny fraction of the overall costs of the whole thing, but it looks great to congress and the average layperson taxpayer so even if it takes longer and costs more overall it'll probably get funded because it spreads those costs out over MORE TIME meaning less cost per year.
Plus I'm sure that you don't "need" nuclear power, you do need a lot of power but that doesn't mean you have to send a nuclear thing. Sending a nuclear thing takes a lot of setup time BEFORE launch anyways, we literally don't have enough Pu-238 to make RTG's big enough for that purpose right now, so solar panels are the way to go.
They could develop some sort of larger flexible solar array (individual cells would be standard solid monocrystalline solar cells mounted on a flexible backing, similar to how the ISS replacement solar arrays are constructed) that would be rolled out over the surface by the action of springs integrated into the solar array trying to unroll it over the terrain once the latches release, that way you don't have to design some complex rigid unfolding solar array with a lot more moving parts and points of failure for the same or likely a lot less power output. And like I mentioned in my first post, if it is decided to use a carbon monoxide rocket, those solar panel arrays could have some sort of hose with regular perforations in it integrated into them to blow dust off of them if the need arises (no wind? Make your own wind to clean off those solar panels!).
Was surprised to see that your a fellow scot 😁 keep up the good work 👏
Howdy from Temple, Texas, USA!
I totally knew when the perseverance mission was going to end up like this sine the first announcement. They made the return mission way too complex. The rover should have carried the samples with it so one mission was guaranteed to grab the samples
Keep em coming
9:21 "An Earth-based clock loses 59 microseconds", per what? Hour, Earth Day, Earth Year?
Yeah, i need answers. if it is 59microsecnods per year, why bother with it you can do a correction every month and it wont matter much. If it is per day then it is a problem.
Per Day ;-)
According to wikipedia (Coordinated Lunar Time article) it is per day. Losing less than a few milliseconds per day is not a problem for a computer network - PC clocks lose or gain much more all the time and the speed of the Operating system clock can be adjusted to correct for that. It is however a big problem if you want to do navigation or astronomy - both require super precise clocks. Light travels about 1770m in 59µs - this gives you an extreme deviation for GPS-like location tracking and very inaccurate speeds for doppler-based measurements.
Looking forward to IFT4. ... ... ... Wouldn't it be epic if there was a camera platform on station at the "virtual tower" location for the booster's catch descent profile and hover. Would make for a powerful PR video!
I miss your Kerbal Space Program playthroughs :(
😂 "there is no hi-five in space!"... Scott Manley. Precious obsevation 24:09
The enemy's gate is down!
Scott! I'm wondering if you'd consider talking about the Decadal Survey in a video, with a Uranus orbiter chosen as top priority over Mars sample return. Could be an interesting opportunity also to discuss the current plutonium production pipeline problems.
It isn't that Funk and Dwight "didn't quite get there." You know? They got there, but were prevented from crossing that line.
Facts
He's an immigrant, give him some slack.
I see the utility of the standing cart moon rover design, but it doesn’t look nearly as classy as a traditional vehicle.
You’re exactly right about stretching falcon 9. They used to have to launch payloads on heavy that they can now use a falcon 9 for. They will figure out how to stretch starship
Wild, talking about Wild.....who ever thought this many rockets being launched was possible
20:02 "No plan survives contact with the enemy." Love it!
Is ""when your best laid plans interact with reality" Scott's own creation?!
Scott! You should consider covering some space adjacent technologies on the channel. Hypersonics are cool too :-)
The jaxa rover concept has an FJ grill.😂
For sample return i would go for a solid rocket design with monopropellant thrusters and a final ion engine, folded in half or in 3 parts for compactness, to avoid propellant boiloff and complexities, it would delay sample return some years but reliability would be great, solid rocket motors have proven in various designs that they reach determined orbits
24:00 when is space a high-five becomes the highest-five. whew! solved that problem so everyone, you can rest easy.
What a time when the main constraint on ISS launches is parking space, like the local mall! I guess that should be a big consideration for Reef something or other and the Lunar Gateway.
Bravo for Japan. Happy that they are onboard with us.
At last, a chance to dust off the "Red Dragon"
Though the streams are swollen, Keep them dawwgies rovin', Rawhide!
Booing starliner mission name: Better late then never but bring screw driver! 😅🚀💥
Somebody needs to repurpose the "the front fell off" meme for Boing's "door" problem.
NASA's new task to develop lunar-time might be quite relevant to Sabine Hossenfelder's latest video about why it's so complicated to develop accurate long-lasting clocks.
0:05 4/18, 2 days early for high time Scott 🤣
Love your channel Scott! Is their an estimate of how many satellites are currently orbiting earth and What types they are (categories) of missions they are?
I find it amazing how many are put into space each week.
Thanks!
Scott, the ISS is fairly high above the Earth. Any five there, I consider a high five.
Hi Scott, could you or your editor add timestamps to your UA-cam videos?
Sometimes I don't have enough time to watch the entire video and just want to hear about the rovers, new suits etc.
Loving the videos, keep it up
I am the editor, and I don’t have enough time myself. I have a day job, family, a house and this odd hobby of mine.
Astrolab's rover looks like a lunar shopping cart. The moon racer looks cooler imo, even if it's the "least suitable".
Doesn't it! Hell, as a former warehouse worker I've operated lifting machines similar to the Astrolab "Rover".
Astrolabs design is a "base operations workhorse", not an exploratory vehicle.
Possible future:
Astrolabs "Lunar Lifter" working at base, unloading cargo, rolling along 3D printed pads, roads and aprons;
Lunar Outposts "Lunar Truck with winch" building outposts and worksites further out;
Intuitive Machines "Lunar Explorer" connecting all and exploring beyond;
While above, GATEWAY crews monitor remote probes.
Standardized equipment for specialized roles.
Delta V is a bit on-the-nose for a rocket name! 😂
Lots of inspiring news.
Questions i hope someone can answer ^-^ , why does the SpaceX starship not use side boosters e.g. use Falcon 9 as side boosters.
Probably to reduce complexity. Also the plan is that the first stage of starship is supposed to land back on the launch pad. If there were side boosters there would be no place for them to land.
Right On
Given everything thats been going on with boeing recently, best of luck to those astronauts going on starliner.
Oh my god I wish that thing was cancelled. I really do think it's gonna kill a crew
@@QuasistellarNymphomaniac i dont think theyll even reach that state because its so garbage, its a now diversity learning device on a large stand 😆
Has nothing to do with Boeing Commercial Aircraft, which is where the problems are. Boeing have hundreds of programs making top-notch stuff, but the media makes money from scandalizing, so you don't hear about it. Starliner has already launched and recovered safely twice. Criticizing a development program is silly. If you need to do that, direct your bile at Starship, which is a deathtrap.
The final Delta IV launch was also the sendoff of the last of the Titan legacy hardware… the huge metal tri-sector fairing from the Titan IV that was retained for these payloads and missions when Delta IV Heavy took over that special role…
Scott, can you do an episode on the "breakthrough" in propelentless propulsion I've been reading about. Sounds like new physics.
24:10 I believe it's a _"Prograde X+0.25,Y+1,Z+0.25 Five"_
The Mars samples will return with the 1st Starship that actually flies back home ^^. Those samples plus like 100 tons more =)
Amazing on NASA for giving Ed a chance to fly. I watch a whole movie on all of that and the politics at the time was very interesting.
Take care scott love you❤❤❤❤❤xxxx
Sure, wing it is a legit strat. The mileage varies though based on where you start. On the education of your initial guesses.
Sometimes you do it right with some help, sometimes get lucky and sometimes you just burn through a lot of cash and time getting there chiseling every inch.
I hope the door doesn't fall off the boeing Capsule...
I truly do not understand how one vehicle, essentially a high-tech car, can cost over $1 billion. It's absolute madness, if you ask me. Is it made out of diamonds or something?
Normal cars on earth are relatively cheap because they build hundreds of thousands or even millions of them and can recoup the development cost over time. If a company builds a one-off car for you it will easily cost in the millions, tens of millions if there is some critical high tech component to it. Now, the lunar vehicle has lots of critical components, its definitely one-off (or close to that), it operates in a hostile environment (imagine driving through fine sharp glass shards all the time, no roads), it has to be easily serviceable and super reliable (try finding a mechanic shop on the moon) and there is the little matter of shipping it to the customer on the moon. All of that combined easily explains a cost in the hundreds of millions, or even a billion.
Maybe they could declare the Apollo 11 landing site as the moon's equivalent to Greenwich mean time zone.
Oooooh, I like it, but I think t would make most sense to have the time zone for noon run smack down the middle of the near face.
I don't think that the Moon needs more than one time zone. It doesn't even need one really.
I think the problem is more deciding on a standard time increment and a standardized method of translation back to Earth time increments than picking where to start counting. Its also very likely that whatever method is chosen will have to be designed with an eye on being applied or used as a basis for application on other planets, so its a pretty huge decision with far reaching impacts.
@@patreekotime4578 No, you don't need 'Moon time' to match 'Mars time'. Mars already has its own time; each sol lasts 24h 39m 35s and so far a martian calendar hasn't been necessary. The Moon is very different, with one lunar 'day' lasting a month. I should think GMT (Eastern Daylight Time, 'mission time' or whatever) should suffice for now.
@@nagualdesign Im not sure you understood the problem. This isnt about "lunar days" or "martian days". It's about relativity causing clocks to count differently on different celestial bodies. To work around the relatavistic problems you absolutely have to have a different way of counting time or converting it.
