Just when you might think SpaceX can’t move much faster with the setup they currently have at Starbase Texas, they seem to kick into a higher gear again. Indeed, the prep work toward flight test 4 is looking fantastic. This week SpaceX's Starship unleashed the fury, and new Insights into Flight Test 3 are here to be had. Also, wow do we have a bunch to cover outside the Starship program. Launch after launch, and also, NASA has some pretty tough challenges coming.

Thanks for the congrats, Marcus! You've always done things the right way from Day 1 and are a super great guy and friend to deal with throughout. Most importantly, it's good reporting in these exciting times, so the amount of new people you'll have attracted to spaceflight via consistently solid content and overviews is good for us all!
Congrats, NSF!
Thanks my friends. It has been such an amazing life changing experience being able to share the stories of space flight and Starbase to the world. You and the entire team have been the pinnacle of the coverage on the ground with the most amazing personalities on camera anywhere in this space. The single fact that three key members of the NSF team have gone on to actually work for SpaceX is a clear example of your incredible professionalism and ability to draw the best of the best into the huge incredible team that is NSF. Massive congrats on smashing that 1,000,000 subscriber mark. 🎉 Super proud of you all! 😍
@@MarcusHouse I hope to be Mars Colonist 250,000-1,000,000.
You all are inspiring this 52 yo to accomplish a dream rejected by NASA in 1989, but reignited by Elon and SpaceX.
Keep up the good work, Marcus and NSF!
@@MarcusHouse.
@@MarcusHouseThank you for the reminder to check my subscription Marcus. Some how I got UnSubscribed...
THAN K YOU for all of the updates!!!!! I look forward to your videos every week!!
Marcus you make my Saturday's a little bit better, thank ya ❤
It is incredible seeing Starbase grow since the beginning
I loved the comparison of flight profiles between F9 and Starship. They have a lot to learn about SS and how she behaves in the reentry regime.
Yep. All very unprecedented stuff. Might take a while to nail it.
Huge fan of how the space news creators get along so well. That’s the way it should be! Great vid
I can’t wait to hear the sonic boom from the starship booster eating the atmosphere. Need a camera in the landing zone. 😮😊
Brilliant !
Thank you for your observations !
Thanks Marcus! Awesome update as always! I might be hungry and needing coffee on this early Saturday morning but I can already hear the kids running and screaming downstairs. Just a few more minutes hiding in bed... Dad needs his space news
lol good luck
Thanks for the update Marcus!
Thanks for a great show. They are all interesting.
Thanks Marcus! Great work and again, enjoyed spending Saturday morning with you!
Mars sample return..
Starship can bring back the rovers too! And put a cybertruck there for later use....
I should have read further comments before posting!
The Mars sample return, while there is a very slim chance of the mission actually being a success and it being well over budget I do think
it is invaluable. To have the capability to send probes to the farthest reaches and return with samples would inevitably save money in the long term.
Maybe I'm just a romanticist though, Nasa did manage it with Osiris Rex!
@@vensroofcat6415 They aren't "wings" and don't generate any lift. The flaps are designed to allow the ship to belly fop into Mars's or Earth's atmosphere in order to bleed off the speed before then flipping the ship vertical a few hundred meters above the surface for the propulsive landing.
@@vensroofcat6415 The entire point of them is to orient the ship and keep it in the belly flop. Stop calling them wings you clueless wonder. You're absolutely clueless. How on earth did you arrive at this channel? It's not for idiots, go somewhere else.
@@vensroofcat6415 Of course it isn't you clown, why do you think the probes we send there use atmospheric entry, a heat shield and then parachutes.
Are you some kind of Russian bot?
@@vensroofcat6415 mars atmosphere is plenty thick enough for heat shields and parachutes. how do you think we land rovers?
Thanks for another great update !
Thanks for the coverage
I believe there was an engine RUD on booster IFT-3 , something hit the grid fin leaving marks, plus the asymmetric engine sequence that followed.
Epic! Looking forward to IFT-4!😎
My Sunday mornings start off great with a Marcus video. Chur bro
Thank you, Marcus. Hope to see you with Scott again soon. That was awesome.
I suspect raptors have thermal equilibrium issues when in a vacuum for a while after the initial burn. The booster relit because only a few seconds had passed since the initial burn. But it was minutes before the final booster burn relight was attempted. During this time, methalox may have evaporated near pump turbines and created a gas bubble that acted like insulation. Which then allowed heat build up from a hot part of the Raptor. After a few minutes the engines are no longer cold enough to safely relight.
This is just a suspicion and i wonder if a Raptor was ever tested on a stand then allowed to sit 20 minutes then relit without precooling. How do we know the failed relite in space was due solely to methalox disruption into the pump and not a thermal shock issue?
Or was the failure attributable to the spinning starship not being in proper orientation?
Space X said no relight due to vehicle roll rate (it was tumbling!).
They always chill the engines before ignition. But as they are using the engines as a re-entry path, without doing an entry burn (as done for Falcon 9 boosters), perhaps the heating transfers from the Raptor Nozzles and then reflected heat is passed to the domed bottom of the LOX section, which would create LOX heating and bubbles. Maybe they need a LOX header tank for the 3 Landing Raptors?
The work pace of this people is off the charts in the aerospace field...
12 hour days, 6-7 days a week. Those salary people are basically earning half-pay for the hours they put in.
It's crazy.
@@wills8288And they're willing to put up with it so that's their problem. I'm NEVER accepting a salary.
Out of this world indeed
@@wills8288 while their boss is trolling on twitter.
Except it's competitors are closer to a viable product?
Thank you for another wonderful video! And you're 100% right about the Chandra X-Ray Observatory. It's a terrible shame they're starting to shut the program down, particularly when the satellite itself has at least another decade of use left in it! This is a bit like moving out of your house and leaving it vacant right after you've paid off the mortgage. All the expensive fixed costs of building and launching Chandra have already been paid, this is the part where they should be getting extra value out of it by extending the lifetime as long as possible.
Also, I love your comparison of the Super Heavy booster reentry to the reentry of the Falcon 9 booster! My guess is there was another plumbing problem with the fuel going into the Raptors on the Super Heavy booster. At that tremendous speed the pumps may not have been able to feed enough fuel against the force of inertia into the engines. During descent everything not nailed down is trying very hard to crawl up towards the nose, so it must be a very stressful time for the fuel pumps.
Thanks for the great recap Marcus. Regarding the booster, I wonder why more is not mentioned about the timing of when things seemed to go wrong. If you look at about the T+6:45 mark of the flight, the booster passes through a cloud layer (incredible sight, btw) and immediately becomes unstable.
Prior to launch, there was concern about upper level winds. I can't help but think there was some wind shear at that cloud layer which the grid fins and attitude control thrusters were unable to cope with. Especially at the speed the booster was traveling.
I had this thought too. Wind shearing was definitely a contributing factor. And yes that view was just stunning. ❤
Awesome clip
Scrap SLS and put the astronauts on a Dragon to dock with Starship in earth orbit then starship to the moon? I'm sure this has been raised before.
Starship will never land humans on the Moon, it is way too leavy, too tall, and the surface too unstable/not flat.
Starship exists to launch Starlink satellites, and maybe other LEO payloads at a later date, moon and mars promises are missions to get funding for other people to pay for it.
@@ForeverNeverwhere1Some rando is smarter than a literal NASA and it will always be /s
This is a viable plan, but there is an even better way!
Get an upgraded service module for Dragon 2, with OMS provided by a vacuum superdraco. In an ideal mission, this wouldn't be needed.
Take an expendable starship, remove the nosecone, and replace it with an adapter. This adapter would have the HLS landing thrusters and habitat inside.
Launch ~10 starships to fill a depot.
Then, launch the Dragon 2+Starship in one launch. The starship refuels, and captures the combined vehicle into Low Lunar Orbit.
From there, it undocks from Dragon and lands on the moon.
After returning to Low Lunar Orbit, the Starship uses its residual fuel to send itself and Dragon back towards earth. The Starship will take roughly 6 months to aerobrake, while Dragon will reenter normally, and splashdown in the ocean.
The only expended component is the upgraded service module.
@@bryanillenberg sounds easy when you say it
SLS is a government jobs program and Washington needs it for now.
You always provide such good and accurate information. I depend on you and Scot Manly to stay informed.
I wish I could meet you in real life. You inspire me constantly and you are so happy making this content. How can I not come around? I wish you well in all you do and thank you for helping the little nerds like me get their weekly dose of updates with valuable information we otherwise may not have.
Great episode 😎 Hopefully they will be able to launch the next Starship within 1 or 2 months.
Thanks Marcus and Team for another episode of Space News goodness. BTW I can now watch your videos in 1080HD clarity, thanks to my new Starlink Sat service.! 314MBs down all day long..!
Ty Marcus!
Excellent video, as usual. If the booster fails to light before landing, it will hit the deck at one hell of a speed. That will be one hell of a sight.
Great job!!
Another great video, thanks mate!
Thanks again Marcus and Co!
Great video thank you
Great round up, as always. Thank you @marcushouse
Thanks
Awesome job😊
Marcus. Love ur shows. So much insight. My thinking on booster failure was too little fuel and too much movement. Fuel has to be settled with no bubbles to ignite properly. They will have it corrected for flight 4. Scooter
Thank you Marcus 🙏😊
Nice job Marcus. Cheers from Italy.
Excellent video as always. Ordered the Ekster wallet crediting your presentation. Thanks.
Hope you enjoy it!
I think you need to prioritize a whole segment on the first Polaris Dawn mission. They are launching in a couple months. New EVA suit designed by Space X has it's debut in May. This is as groundbreaking as Starship. First space walk by private company (not NASA/Russia/China. Furthest distance from Earth by humans since Apollo. Suit may be used on Moon/Mars. I just wish Space X would do about 20 of these missions instead of a couple, so we can learn to live/work in space while Starship developed.
If I am right, the funding is coming from Jared Issacman and some of the Institutes and Universities that they are doing testing for, as well as SpaceX. So I don't think that 20 missions could be funded by Jared, on his own. He would need some taxpayer funding and/or large corporations to fund him.
Don't you worry, the Polaris Dawn missions will be a solid focus for this channel, we can't wait either 🙂
Another excellent video Marcus.
Awesome space roundup. .
Hope the budget isn't cut too much
Imo it's money well spent
Thank you MH + Team for another good upload
They should do a loop in that line.
in the days hen the spitfires flew.
They had such issue on their fuel lines.
A farmer told them just make it longer and make a loop.
It acts like a detention spring.
there will be virtual no more stress on it at all.
I would just like to say I've been hooked to this channel ever since a friend of mine recommend you Marcus house from the first falcon heavy launch to the early star hopper days all the way to the detailed and of course always education dissection on all flight tests who can forget the awesome updates (I strictly get from you) on the starlink missions and booster landings.
From South Africa a 3rd world country 😂 I'd like to say thank you ❤for the education and the inspiring passion you've always shown us week in and week out thank to your team as well. 🚀🌎❤️🌞
Hey thank you for taking the time to write in. Awesome to hear you've followed along for all that time. Then channel has evolved a lot with extra help over all that time. I hope I've managed to keep the same flow and interesting topics as you've travelled along with me. I hope we get to do it for a lot longer yet. It has certainly taken longer to see the Starship program evolve than we had initially expected, so I've learned that patience is a virtue with all this. A lot is riding on the following missions that will prove that this Starship idea will indeed work as planned. It'll be a dream come true if so and to me at least it is looking very good so far.
I didn't know that Africans liked space.
cheers

Hi Marcus thanks for your great updates. Possible reasons for the booster's issues - PIO, pilot induced oscillation by the grid fins, i.e. over correcting and then having to correct the other way. A software fix? Ever swirled the last bit of liquid in a glass, this could be the reason for the lack of raptor engines re-lit. Also the aerocovers housing the COPV's would act as fins at the wrong end of the booster creating much instability. Note that the booster is basically an 'Aircraft' not a 'Spacecraft'. Remove the aerocovers and COPV's and place spherical COPV's above the thrust puck, re-light only 8 raptors 5+3. My 2c worth! Keep up the great work.
"Partnership", love it 😆
Great video Marcus; I was wondering if you believe the segments for stage 0, lunch mount and other sections at the CAPE will be used for 2nd lunch tower at Boca Chica?
shutting down Chandra for science is like a doctor trying to detect a fractured bone with an IR cam... we would detect a spike in heat around the area, but wouldn't be able to see if the bone is really fractured... I hope someone can step up and continue the work with Chandra
Thank you, I enjoyed that. It would be interesting if you could tell us which launch of the year you are talking about. Perhaps you could add that next time?
Great content as always Marcus 👏
Are you interested in covering Gilmour Space content? We are launching Australia's first owned rocket, really soon!!! 🚀
I’d watch that!!
I wondered if it would be better to have separate launch & landing pads. That would protect the more intricate want systems, and the landing pad could be purpose-built to focus on just the necessities of catching the rocket and be a much more simplified system that may be built a little more heavy-duty. It would also make launching more efficient as you Good weekend pass inspections right after takeoff & wouldn't have to remove the landed rocket before a new one is rolled out for takeoff
I think the reason the BQD hoses were broken was due to the connection of them being stuck so they had to cut through it. Great vid as always!
Starfactory progress is such a big step in the Starship program; moving from prototyping to manufacturing.
Thanks!
Thanks a heap!
Thanks. Very smart to look at budgeting. Any way to do that for other countries? All the best
Woo!
Hi, Marcus. Thank you for another fantastic video. Do you think that a bigger landing platform would be appropriate to service and reload Falcon 9 at sea, reducing the trips to shore and the speed to relaunch?
NASA's budget has hovered around 25 billion for decades now. Some years it goes up, some years it goes down. The really interesting thing is that the Space Force budget has already exceeded the NASA budget (29 billion) and will only increase in the coming years. It's sad to me that the ability to punch someone in the face is more important then exploring the universe, and acquiring knowledge. But this just shows that the home world is still a dangerous place to live, and such things are regretfully necessary. EDIT: It looks like this is allot of money to some folks, but to put that number in perspective.. Americans spend over 750 billion in bars and eating out. Just food for thought.
Crazy
One of the many reasons Trump started Space Force was to fund space research via defense funds, due to poor leadership like in the past were the cuts crippled programs.
@@greatwhiteevox1008nah, trump started space force cuz space wars and that silly idea (for now)
With the ROI from space exploration, you’d think the US would be dumping a lot of money into space travel/research. I’ve had the thought for a long while that the military and NASA should have a combined budget. Then NASA focuses on propulsion systems for earth based vehicles as well as their space vehicles- NASA and the military both get new tech. In theory it would cut costs down to open up resources for more exploration but I doubt the military industrial complex and the politicians giving nasa these wasteful contracts would allow that to happen
Glad we ended up drinking and eating
So EXCITING
It would be amazing if SpaceX could add a camera in the engine bay maybe above the blast shield and a camera looking at the thrust puck.
Love the cut to your sponsor in the middle of NASA budget cuts. I thought for sure you were going to say "And now a message from today's sponsor so that I don't have to take a budget cut." 🤣 Admit it, you know you were thinking it. 😜
Came here for wallets, stayed for space news!
Can we see the shape of a possible huge corner window at the new production building? 🤔 (High bay side)
Great content every video, congratulations to the team.
With the booster falling that fast, fuel would be floating and hitting the sides of tanks making course correction unpredictable.
It needs two deorbit burns the same as Falcon9's. Control trustees on both vehicles seemed to be unable to correct the roll, may need beefing up.
As a Guess: On the telemetry readings it got to 0km in height, but was traveling at 1,172km/hr and was well above the sea. So the control software for the Grid Fins were operating at an expected low speed and this 'oversteer' induced the high oscillations. Someone forgot to tell the Raptor engine software the 'Raised Landing Height' and it was operating off another input (the current correct height), so when they tried to re-light, the induced oscillations caused sloshing, which is a 'killer' for hungry Raptor Engines! Hate that when that happens.
great again
Thank you Marcus. I live in the UK but my best holidays were in New Zealand, close to Tasmania. Love your work, thank you. Oh BTW my puppy Dalmatian get's fed up with me watching your video's as he wants to play 🙂 Oh & the Starship Landing went horribly wrong. I already have a T shirt from you 🙂
Yeah, only 1,731km between Hobart and Queenstown airports. Glad you had a great holiday in NZ. Kiwi David.
I loved it so much I visited twice. Bit expensive from the UK but totally worth it. I would move there if I could.anyone want to pay anyone could pay flights for my Dalmatian & I :-)
Finally IFT 3 merch! I was hoping it wasn't cancelled 😅
I want to know what put the marks on the grid fins at engine start up for landing burn.
Starbase already looks cool imagine when the factory is finished 🔥
One of the best thing about Saturdays. Hey hey, it's Marcus House.
I think some of the engine plumbing on the booster probably got damaged by the atmosphere. Maybe some internal plumbing as well. I paid close attention and it seemed like there was a wee bit of negative acceleration again.
All ways a good watch
Marcus, Excellent!!! BTW, do you have any more of the Starship Flight Test 1 or 2 merch./mugs?
Great videos, thanks Marcus and team! In this one you reference 'gigantic' forces on the engines as they head into the atmosphere at 4000kph+; and that the deceleration was around 3G. I believe (but could be wrong) that Starship is expected to accelerate at 3-5G at launch.
Thinking about it, this 3-5G acts through the expansion of the rocket exhaust gases upwards against the nozzles; which is also where the air resistance would be primarily acting on descent. Given that the forces at a given G would be greater on ascent due to more fuel being on board, shouldn't the engines be more than capable of handling the forces on descent? Perhaps they just need more shielding around the nozzles so that the air resistance doesn't hit the rocket internals behind the nozzles...?
Starting some engines early in the decent might help with slipstream and pressure issues around the perimeter of the engine bay. Space X probably has models for all this, but computer modeling only goes so far, look for changes on the next flight, I think they start 3 center engines early in the decent and keep the on all the way down.
"Partnership"
I like that.
Great to see
You really made a UA-cam account just to post this comment
@@Mass_peach My first you tube keyboard warrior, I’m honoured you sad man 😂😊
Thank you, again, Marcus. The budgetary travails of NASA are troubling, though not a new thing. I wonder whether the successful (we hope) development of Starship will enable the agencies dollars to go further... I also wonder whether the SLS will ultimately be axed (as, in my view, it should be).
large observatories have made adjustments to the idea of the place we are in ))
I would say the green exhaust was TEA-TEB, but the raptors are electric ignition.
Hey Hey Marcus!
I think the rotation caused the propelants to work outboard, resulting in inadquate supply for the start. Get the roll rates under control on decent, and propelant wont be sloshing up the walls.
Mesh sleeves are typical for hoses that have sharp bends.
They need to make where the bottom hose connects pivot with the shield so theres no flex
My guess (hey we are all guessing right now) is that the propellant was at the top of the tank again and it couldn't get to the bottom. I think it needs some kind of "startup tank" right at the bottom - like a buffer tank - that is always full, always at pressure and can feed the engines for a few seconds so gravity can move the fuel back down again.
But as I said, I'm just guessing from that green tinge too.
A smaller slosh tank with one -way flapper valves is sometimes used in aviation to control movement of fuel in a large tank. A cone shaped partition towards the bottom of the main tank might work as well. I think Space X may not reveal too much as to not give China a blueprint for their copy of Starship that they are working on.
The Merlin powered Boosters have been well tested. I think the Raptor Booster Grid Fins may not be big enough to induce a higher negative G force to compress the 'slosh/bubbles' out of the propellant, or the higher re-entry speed caused heating of the LOX dome, which induced bubbles in the LOX.
My other 'guess' is that SpaceX raised the landing height from sea level, in order to test the hovering control of the Raptor Booster. On the telemetry readings it got to 0km in height, but was traveling at 1,172km/hr and was well above the sea. So the control software for the Grid Fins were operating at an expected low speed and this 'oversteer' induced the high oscillations. Someone forgot to tell the Raptor engine software the 'Raised Landing Height' and it was operating off another input (the current correct height), so when they tried to re-light, the induced oscillations caused sloshing, which is a 'killer' for hungry Raptor Engines! Hate that when that happens.
hi Markus how do they recover the boosters from the drone ships love the videos keep up the great worrk
I believe they lost another bunch of tiles during the ship static fire - likely due to vibration and shock waves. The TPS is still flakey and I don't know if it's even fixable although I guess the new flame trench is going to help.
Those tiles were not installed even before static fire
I wonder how much testing with the higher air pressure and wind was done, could that backpressure have created issues getting the engines back up.
With jet engine aircraft, you cannot start them with a strong wind from the rear of them, doing so can result in a failure to ignite, or ignite properly causing damage. With the increased velocity coming in, it’s possible it was too fast to ensure a proper engine light.
I think the term is 'A flame out'?
There must be a difference between the Merlin Engines and the Raptor Engines, that SpaceX did not take into account, or the Grid Fins need to be bigger on the Starship Booster, to create more drag, that will then reduce the speed for a re-light and create a higher negative G force to help expend bubbles from the propellants.
My wife is on the PS5. I sat down and she said, do you want Marcus on darling?
She's a keeper❤
100%
I SWEAR I SEEN THAT WHEN IT WAS LIFTING OFF,!!
Another excellent video! Thank you. I thought many of the instruments on the Chandra telescope were failing. Not really a way (right now) to repair them. How would they continue running it?
Nothing that is a game stopper. If they can't keep it running then sure, cancel it then. We have no replacement coming for this.
I’d like to see more countries working together to fund these telescopes and research missions.
We are watching "3-Body-Problem" Series. Would explain alot :D
Updated Marcus Cheers! TFS< GB :)
On the landing of the SpaceX' Booster.There was not only an issue with the engines, but some aerodinamical control problems as well - the movement of gridfins didn't look coherent or adequate especially at the end.
