This has been quite the day! 🙏🚀🎉
23 hours? Come on man! LOL
Well done summary. Yeah quite a day, still haven't got to sleep yet, just too much excitement (now over 30 hours). But I'll retire now. Thanks for all you do. Best, Tony
One big step for SpaceX and space science! 🚀💫🌎💪
..."quite the day"....that's the understatement of the year right there!!!🤣 and wat a treat it was watching the NSF Stream with you as a presenter !! "Quite a day" ... !indeed
By far the best channel on this information. Keep up the good work Marcus! And team
Those epic shockwaves at launch, wow!
What about the sound? It hit the microphones 20 seconds after launch. This was an epic moment, can't get enough of the footage.
7 decades of seaside launch. Talk to NASA.@@nommy8599
@@BluelagoonstudiosI watched some footage from South Padre Island and the sound was mental, rhythmic pulses of raw power, it was like a rock concert!
@@nommy8599 And most fish can feel sound in the middle of their spine, launches at sea, not gonna happen.
@@aldunlop4622 I watched the video from Ellie in Space, first silence and then hell broke loose, I had the footage on the big speakers in my studio, and everything was shaking lol
The engineer in me is still flipping out over the shockwaves emanating from the base of the vehicle as it "hitched it's skirt up" in preparation to leave the launch mount. Just look at the amount of visible shock waves despite that deluge system.... and still, the surrounding area seems to be mostly in one piece 😮 we just launched a stainless steel building high into the heavens and 100 odd years ago we'd only just worked out how to glue cloth over wood and fly a few hundred feet over the ground
Good call bro.
They used to say that Saturn V was the weight of a navy destroyer - Super Heavy is a light cruiser!
Things are looking up!
and those shockwaves were rad
I feel like humans advancement increases exponentionally. Imagine 1000 yrs from now where we’ll be.
@@Jumpingjackflash123 Hopefully making babies on Sigma Draconis 7 and other destinations.
Im old enough to have watched the Apollo flights as a small boy. I have never lost my interest and astonishment with the reach for space.
To see humankind stretch out again is so awesome. Thank you SpaceX.
Ditto!
Giday there,
I will second that,
But it seems so long between drinks / I
. Meet flytes
This is fake and so we’re the Apollo missions. Sorry to be the one to tell you guys. They’ve had us living in a fantasy land for a long time but people are waking up in huge numbers.
@@davidmorris65392:44
This was one of the best post launch assessments on the web. Great job focusing on Stage 0, the key to a third lunch attempt.
The fact that the 33 Engines still running after taking off the Launchpad is an amazing feat itself. Glad to see the Water Deluge system is working well
@@wizzyno1566That is still too much for 3 flights per day.
@@streamtabulous Still a huge accomplishment than the last launch. Probably they will add some more modifications to the water deluge system to be more reliable in future starship missions without refurbishing every launch
Yeah, a rocket based on unreliable engines would never be successful. It was great to see them all lit.
true, but 33 engines also 33 optys to fail.
@@markussitzmannthey’re not close to that yet so they should have plenty of time. Every launch they’re learning from what happens and trying to fix it for the next launch
Having all 33 engines firing all the way to MECO plus having a successful hot stage separation was incredible and both massive achievements. Anything afterward was just icing on the cake
Customers only care if their payload gets to space, so it was about 95% successful…
@aldunlop4622 any test flight is successful if you get farther than the last one and learn new things. Which they did. It's unrealistic to expect everything to go off without a hitch on only the second flight of any cutting edge vehicle.
@@aldunlop4622 Fortunately, this was just an early test flight, not a commercial flight with payload. Sort of what 'test' flights are for...
@@WonderfulAircraft precisely…
@@ChristLink-Channel precisely…
This flight has eased some of my concerns about Starship, and it looks like SpaceX has been working to constantly make each launch and flight better.
So glad your concerns were eased, they are so important.....
@@robsoler2604
Do you wake up in the morning and decide to be a dickhead or is it something that comes to you later in the day?
If ive learned anything about spacex is they iterate physically. most companies find it too costly to blow up their vehicles while in the prototype phase, spacex views it as a marketing cost, and to get some valuable hard data.
@@Robb1977
Agreed.
It's also important to keep in mind that SpaceX's main goal is MASS PRODUCTION of Starship. They've built several of these things already, each one with improvements that the previous doesn't have. Most of the cost has already been spent before they even get to the launch pad. Might as well launch them even if they know it probably won't make it to orbit.
MARCUS! WOW MAN! what an unbelievable flight! My 15-year-old son and my 11-year-old daughter woke up to watch this with me. I was watching the live stream of it from 4am and never went back to sleep because my heart rate wouldn’t allow me to. Thank you so much for posting this video. It’s amazing. Thank you for all you do and keep it up brother!
Ahh, that’s heartwarming. Little rocket nuts like us!
I was absolutely ecstatic when I saw all 33 engines running strong!
We all were bro! I was dancing around my living room haha.
Ha ha me too !
That was quite an achievement. The Russian N1 never got that far.
FREEMASONIC 33 RAPTOR = LIZARD ENGINES WITH 6 EXHAUST PLUMES OF SMOKE AT LAUNCH ? GET RIGHT BY GOD ALMIGHTY .
@@StillAliveAndKicking_ N1
That separation event was incredible 😮
So was the explosion.

A perfect test of the FTS. Should ease any concerns the FAA had about that. I love it when a “fail” is such a success. And a stunningly beautiful one at that!
@@ReinReadsDid you see the astronomy RUclips guy that managed to get Starship on video filming from the Florida Keys? But it turned out to only be the nose cone section! So the Starship FTS basically broke the vehicle in half. In his video that was livestreamed last night, you can see the nose flaps and the whole piece spinning as it tumbles through the sky. Crazy that someone got that on video...
@@ReinReads Most rockets launch without ever testing the FTS in-flight... so Starship has by far the best tested termination system in the business, and they're not even doing real launches yet.
It’s very nice to see the various SpaceX RUclipsrs working together for events like this. The sense of community is amazing!
0:09 always impresses me how you can see that shock-sound wave expanding just when they light up the engines. Great stuff!
Hey Marcus, I really appreciate the second episode this week breaking down the latest launch. I was cheering out loud in the living room when I saw the hot stage separation! How cool was that!!
Yeah I think I may have blown my load then haha.
It was very cool! Or rather, very hot...
This launch was night and day compared to the first one. It was an epic launch.
the previous one was also VERY exciting with all the tension of if that thing would go up or not after almost being covered by dust and debri
It was the same thing. They both exploded, and for different reasons, which is even worse from an engineering perspective.
At this rate, it’ll take 20 launches to get it to be human rated. Which is several billion dollars worth of money wasted.
Saturn V was much more successful.
@@jeffw8218 you clearly don't know the amount of money thrown at apollo missions or do you?
So Pathetic of you from my perspective...
Didn't see anything
@@jeffw8218 in terms of money not even close, literally costs 10 times less to launch starship
Marcus, what a marvelous and professional condensed summary of it all. What a wonderful spirit of cooperation by your other industry producers - all true professionals.
Thanks so much, this is a milestone keeper...and just the right length - 13 mins!
I'm calling that a success. Yes both booster and Starship didn't make it to the end of their scheduled paths, but the improvements from the first launch just out weighs everything. The amount of data gathered is invaluable!
You know this was a failure, don't kid yourself.
@@TheDarkerAgeshow many apollo launches to the moon? Take into account that they weren't reusable.
This is the kind of historical events I don't mind living through.
100% agree! Such an exciting time for space exploration, the late 60s were like dipping toes into the water, now we’re deciding to walk straight in.
Historical? They tried this in Babylon and it failed aswell.
Historical? They tried this in Babylon and it failed aswell.
The best post flight account so far. As usual the media gave a superficial analysis.
Best brief ever Marcus, your awesome. The best part is no part. Same in your reporting, to the point with minimal words spoken. Thank you!
Wow, thank you!
Thanks, I was expecting the best Starship video from you, and I was not disappointed. To the point, and just enough detail. What a superb flight, if only they’d created a proper pad for the first flight. So much went right this time.
This was a fantastic launch and very good progress, and yeah, completely agree about first launch. I was talking to friends about it who aren’t space enthusiasts and telling them that I was afraid for the launch pad, and they were all saying “it’s concrete, it’ll be fine”. 😂 I pointed out that all previous launches of big rockets have had water curtains or some deluge system, and it wasn’t because the space agency doing the launch felt like spending extra money and time on it. Anyway, I’m very glad it worked properly this time, but given that the plates and everything were being installed immediately after the concrete remediation took place, I suspect the entire system was basically fabricated but they (quite possibly Muskrat) simply didn’t have the patience to wait for installation and testing of it.
@@sjsomething4936 I believe Musk said that the deluge system was ready, but too late for the launch window they were allocated and so opted to see how the new concrete pad worked. The water curtains at other launch sites are not for thrust mitigation but for noise control due to the proximity of habitation. NASA uses an exhaust tunnel to dissipate the thrust which requires their huge, elevated gantries which SpaceX was trying to avoid the cost of by setting up so remotely in Texas. Also, I would think that any deep excavations at Boca Chica would be a problem as it is built on light sand banks with a high-water table.
@@trevorstewart8 ah ok thanks for that info. Too bad about the timing because that was some very bad press that resulted from it. I believe the deluge curtain and water curtains are also to prevent acoustic shockwave damage to the engines and engine nozzles, not just for protection of the launch pad and surrounding surfaces. I’ve heard the same about the location, it doesn’t permit digging of a flame trench etc, so the elevated launch pad design (and unique deluge system) was necessary to make the location viable. Cheers, thanks for the reply.
Between you, Scott Manley, WAI and Everyday Astronaut I’ve got at least a couple of hours awesome space video every week!! 👍😊😊
I’m subscribed to exactly the same; no more, no less.
Scott Manley got to heart what had happened nearly right as it happened. He did awesome job picking it out. Fuel hammering makes sense. It was always concern.
I don't watch EA. I watch WAI
Matt Lowne also produces a great weekly review.
NSF and Lab Padre also... Need more monitors! 😎
I watched many recap videos, and was on site for the launch. I wanted to let you know that your recap was REALLY informative and unique. Your breakdown and comparison of IFT1/OFT1 was really cool. I'm writing my own articles about the experience and sharing many links to other people's perspective, but I'm going to recommend yours first as it really does a great job at explaining things to people who may not know all the details.
One more step to the Moon and Mars! Congratulations Space X
As always, welll done Marcus. Scott Manley also has a detailed analysis of the launch that I found informative, for those who can't get enough of that kind of thing.
but no Stage 0 flyover. You gotta to catch em all !😀
Yeah it made a lot of sense.
Compare Marcus with Felix ......
No comparison. Super technical analysis and footage from Marcus.
Felix, however .......... I was disappointed
Also channel Astronomy Live captured images of the disintegrating upper stage from the Florida Keys with a stabilized 11 inch telescope. You can clearly see the still intact nosecone and fins.
Felix was more interested in his Xbox controller...
EXCELLENT report! None of the negativity of the nay-sayers, and still accurately describing what we could not ourselves witness.
Congratulations to SpaceX, and the Marcus House Team!
Marvelous Launch, and Marcus House coverage!
The naysayers are just Musk’s political opponents. Secretly they admire him.
Thank you, Marcus! You always manage to add something new. As far as I know, you're the only one who noticed the staggered shutdown of booster engines prior to stage separation. Great attention to detail!
That in particular was really cool to see.
@MarcusHouse Somehow, I think this shutdown sequence will inspire a new Christmas light display that only Starship fans will appreciate 😄.
I was there. I was totally not expecting the launch to push the sound into my chest. I could feel the launch in my body. Wave after wave of shock hit us there in South Padre.
That was a pretty amazing launch! To me, the Raptor engine was the most critical part of the equation and seeing all 33 Raptors firing up until stage separation showed that SpaceX made an immense amount of progress in that area. Maybe the fact that the RVac on SN25 are a year old contributed to the fact that the ship failed during ascent. I am really curious to find out what really happened. But what a spectacle to witness!
All 39 Raptors working perfectly!
Scott Manley has an interesting take on that -check it out!
@@jonathanjehan2284 Yes, he suspects fluid hammer or something other related to propellant. Could very well be, but we won't know for sure until SpaceX releases some information.
@@ShadowZone Yes, he suspects fluid hammer or something other related to propellant
Could be sloshing creating a vortex allowing gas to be sucked into the pumps instead of liquid.
They worked because this time none of them has been knocked dead by concrete fragments of the launching pad. And this is the biggest progress.
massive improvement since the launch, also a reminder that a failed test launch are far more valuable than a flawless one. especially this early into the development.
Cope.
@@OurCognitiveSurplusCognitive deficit.
@@OurCognitiveSurplus how is this cope? it is widely known that a crash, explosion or in general failed launch offers far more data than a flawless launch. its the same way in all aspects of life, failure is a much more effective learning experience than sucess.

Thank you, Marcus. You NEVER disappoint. You can chalk this one up as another in the win column!
The hot-staging itself, looked like a beautiful nebula.
Marcus! You were great on both streams, was very neat to see you collaborating with and supporting fellow aerospace creators as you so often do.
We appreciate your work. Ad astra per aspera 🚀
Well said sir. SpaceX needs to hire Marcus to do the live broadcast.
Agree. NSF is my favorit coverage site plus their launch streams. They have fun people to watch. (they're quite smart too) Good to see you over there. The launch was awesome to see. Can't wait to see more. 😉
@@JeromyBranch I miss Jessie. Her voice is like butterscotch.
Thank you so much, Team Marus, for this incredible recap of Launch #2!
the most beautiful part about the launch, in my opinion, was how the exhaust plumes combined into one massive single plume, and you could see the mach diamonds in it with perfect clarity
Kudos to the drone pilot. Amazing footage.
A lot of hard work by talented engineers, tradespeople, and technicians. The 3rd flight is going to be very interesting.
The engine shutdown sequence before hot staging was SO FREAKIN COOL! I'm glad you pointed that out, it seems so many channels are glossing over that. Thanks for the awesome coverage Marcus!
Wonderful breakdown of events as usual! This test was awe inspiring to watch and just feeds my hype for the next one. The sight of those 33 engines glowing as they push this huge stainless steel monster into the sky was pure scifi imagery.
Outstanding job on this report Marcus! 👍🏻🇺🇸
A couple of the other channels just sit there and gripe about negative media reports, while you consistently push forward with the accomplishments and hurdles that have been overcome, while keeping your story focus headed onward and upward! 🚀
At what cost though,. Sure if you throw enough money at something and time you can achieve it but is it economically viable with what this conman has planned for it ,no.
@@ageofatheism6638 I pity guys ike you. I know you are just looking to have a bitch session. Just let it all out and get rid of it if you can
@ageofatheism6638 do you support the US's absolutely insane annual military budget? It's an order of magnitude more than NASA or any space program has. I absolutely agree that Elon is a crazy guy, but at the end of the day a lot of brilliant people are, and that doesn't change the feats they've accomplished. At the moment, nobody else is working on a rocket this large and powerful, and it's extremely important for humanity as a whole to continue to develop our technology and progress as a species. That's how we got where we are today. So this is one of the big steps we need to take. Plus, SpaceX's mission is to produce rapidly reusable rockets. That's something to admire.
@@ageofatheism6638 So where is the con?
You dont believe he launched the biggest rocket in the world?
Bear in mind he is paying for this with private money.
From profits from the falcon 9 and starlink and investers.
@@ageofatheism6638negative Nancy relax. These ships are not even a drop in the bottom compared to our annual military budget as my guy just said. This isn’t anything. These advancements will benefit our country and even the world. You should be proud and happy for the scientific advancements this will open up with upcoming trips to the moon. Eventually becoming a permanent base.
I can't wait for a full break down of the launch site and comparisons to the last. Truly exciting times, congrats to SpaceX
That lunch was so awesome great update Marcus and team GO SpaceX!!!
My birthday was yesterday and having a successful launch with all 33 raptors and a successful hotstage was an amazing present from Spacex!
The second IFT was phenomenally better than than the first one when you consider what they had to do after the first one, repairing stage 0, improving the booster, all in just 6 months. Also, they didn't have any data about the ship on the first one, they didn't know how it would behave after its separation, now they have the data to work with, and I hope the next launch will be fully successful 👍🏻
I heard the first stage experienced a negative acceleration during separation. I thought part of the reason for the hot separation was to avoid that.
@@ernieschatz3783 The reason for the negative acceleration was the flip maneuver that happened too quickly
Test flights are done to TEST craft and equipment for further refinement. This flight was a huge success in gathering the data for this purpose and any delays while getting on with the next launch will be necessary to address component failures in the test craft. Congrats to SpaceX to the giant strides they are making toward the future of reusable boosters and spacecraft. Thank you for the coverage Marcus and crew. "Data gathered is Knowledge expanded".
Exactly.
I suppose, but I would stress the term “iterative testing methodology” when saying that.
Yes, it was expensive and took forever - but Artemis I w/ SLS was a “TEST craft” also, and achieved about 20x the (far more complicated) milestones including all staging, multiple burns and trajectory changes, lunar orbit, successful return, all WITH a complete human-rated spacecraft and life all support systems working flawlessly to splashdown.
On its first “TEST” flight.
I appreciate the way both programs are approaching these vehicles, but you’ve gotta have some respect for NASA also (with all the baggage and fine print / caveats that come with it.) Artemis I was just incredible when you consider there could have been humans in there the entire time, going to the moon and back safely.
People seem to forget that starship is an empty shell, even when it does fly a successful mission/orbital insertion, it’ll still be an empty shell.
When you think about the exponential increase of components like complicated life-support systems that have to be developed, tested, certified, built, flown, etc… it seems SO far away still, even if IFT-2 had been perfect.
The thought of having zero pad/launch abort modes and zero reentry contingencies at all (ie. tile damage during launch, or any engine failure on reentry) scares the hell out of me. Might as well just use crew dragon for ascent and return, and transfer to/from starship in orbit.
"A huge success"?!!? ah modern space fanboys! "A huge sucess" Hahaahaahahaaa haaa ha
So true! But try telling that to the media channels: once again they are yelling that Elon's rocket was a total failure, because it blew up again. It seems the concept of "test flight" is beyond the grasp of the meager mental capabilities of the average journalist. And of course, when the futre flights start succeeding all the time, they won't even bother reporting on that. TO them, "success" is not newsworthy at all.
@@count69 Ummm... it WAS a huge success. Major improvements in all aspects over the first flight test, and they now have truck loads of new data to go over, so they can figure out what went wrong later in the flight and fix that, ready for the third flight, shortly.
Booster:Kaboom!
SLV:Kaboom!
SpaceX:Yeyy!
Thanks for the breakdown Marcus. Brilliant as always! Absolutely historic stuff we're seeing here...
Scott Manley speculates that fuel hammering and starvation killed the booster, and even the SpaceX live stream hosts eluded to that when it happened. Fuel slosh in zero g is quit the headache, and a giant elongated tank makes that so much worse. I would love to see their solution, but that is one of those things they fix, and we never see
The solution is simple. Just leave more engines running so the thrust of Booster equals the thrust of Ship. They only have to make sure the hot-staging ring can handle the extra pressure.
I agree, Scott Manley's analysis I think is very accurate. I think we might see similar to what is used in aerobatic aircraft, perhaps a smaller dedicated tank with a flop tube, that orients with gravity. Sometimes baffles and one-way doors are used inside fuel tanks to control fuel flow in unusual attitudes. Maintaining fuel flow and keeping air out of fuel injection systems is the key here. A slosh box in combination with baffle plates might be some of the modifications made to prevent air getting into the engines. Fuel tank design can be trial and error, we might see some of that here.
Wow Marcus, that’s the best breakdown of yesterday’s launch I’ve seen anybody produce. Keep up the good work.
Thank you Marcus for bringing us a positive review of a fantastic achievement. Not like others. You are the best. Keep up the good work
Scott Manley did an excellent video on what happened to the rocket and booster. He noticed from the display that the oxygen suddenly started going down very fast towards the end. He also zoomed in on the rocket as it was accelerating and noticed it was losing a lot of heat tiles!
@@Mr_Marcus_House.. I feel as if SpaceX can nail the first part, nearly accomplished and the easy part, the next part; re-entry, is going to provide numerous engineering headaches!
@@marcuswardle3180 That is a bot pretending to be marcus.
@@marcuswardle3180 Just report the comment, if you pay attention to the name and the very basic comment that has nothing to do with your post, you will realise its just a scam bot, i have reported about 20 from it so far on different posts, the channel owners name will always gave a grey box around their name and also a white tick in the name box.
The heat tiles may turn out to be the biggest headache. There is no tolerance for even one tile falling off AFAIK, although such a shame the ship did not make it back to reentry to find out,
@@Tailspin80 We don't know that... we've no idea what tolerance there is for missing tiles. Obviously Shuttle didn't have any tolerance, but that was a mostly-aluminium skeleton beneath the tiles... Starship's steel hull should be more resistant. I imagine that was one of the things the SpaceX engineers would have missed most about the way this ended... seeing it attempt re-entry with imperfect shielding would likely have been more useful than having all the tiles stay on...
This is a remarkable achievement it should be celebrated. Can’t wait for the next one
I had a blast, seeing that beast going up. Probably see this event about 20 times now, including the live coverage. The mind boggles! Love to see the bright white engines with that metalox fuel.
Amazing work by SpaceX. they are almost there for a perfect launch. lots of learnings and increased probability of success in the upcoming launches
I can watch this launch over and over.
Wow what a flight it was! Thanks Marcus and the team!
Fantastic summary of yesterday's momentous event. Thanks for this - can't wait for FT-3!! Go SpaceX. (from the UK)
I don’t know what happened, but yesterday watching this live I started to cry uncontrolably. Now mind you Im a pretty big fella but that had me weak. I felt so proud for all of mankind that we managed to get so far. SpaceX is breaking boundaries and sooner or later everything will run smoothly. Just incredible
It doesn't make you weak mate, it just means your in touch with your feelings and not cold hearted, you were pumped and excited, that's all, i was the same, don't be ashamed of it mate.
Im pleased with the result. Alot of progress was made and spaceX will figure this all out.
Have seen also others covering this event f.e. Felix, and I really liked your direct comparison with the first flight.👍Great idea!
Thanks for the summary and the frame by frame analysis of the unknowns. This launch was one of the most epic moments of 2023, for sure.
Knowing now the self destruct mode works is so gratifying, beautiful. fantastic, awesome…….I’m so amazed it leaves me speechless! 🤔
I remember watching the livestreams around SN10 +-2 like 3 years ago, so I have a lot to catch up on and it will be fun
Thanks for the super quick analysis, Marcus! 😊
Awesome moment in the history of space flight, and watching Marcus on the NSF live stream in the lead-up was just icing on the cake!
An awesome moment in the history oif space flight!?!? Really!?!? The thing blew up! And we're as far away from the moon as we have ever been! Apollo managed this first time without failure there was non of this tip toeing ever so slowly and every other thing blowing up! All this 'progress' and we're still barely even a shadow of what Apollo achieved. Why is it so much harder now we have far greater technology that the 60s?
@@count69 because it's a much bigger rocket, 33 engines on a rocket has never been proven to be effective, strapping a 2nd stage capable of deliver 150 tons to orbit has not been done, much more progress per failure than apollo, less expensive, and will be more refined.
to elaborate, NASA uses simulators to make sure their new rocket doesn't explode when it launches, although this might seem a better choice, it is more expensive and it isn't efficient since testing in simulators cannot take into account factors in real world scenarios. SpaceX is the opposite, they launch, and when it fails, they make necessary modifications to the next rocket, which is faster, more efficient, and cost effective, it also prepares them for potentially a quick cadence of launches since they can determine how much of an impact the rocket makes on Stage 0.
Apollo’s budget (Planetary Society, inflation adjusted) was $257bn. Starship is estimated to be $5bn, including all ground facilities, which are still being developed to crank out new ships at an ever faster rate. The first Saturn 5s had major problems with combustion instability, and these had the legacy of the Mercury and Gemini programmes to build off of.
Developing a totally reusable rocket has never been attempted. This is a fantastic achievement and things will only get better.
@@count69there were multiple objectives they were trying to achieve with this launch, including 1) demonstrating that the water deluge system had solved the rocket tornado issue, 2) successful demonstration of hot-staging, and 3) confirming that the second stage could make it "close enough" to orbital velocity, all of which were a monumental success (not to mention all the incredibly useful data they got from it). the fact that this is all being done on a rocket that is 1) much bigger and more capable than the Saturn V, 2) developed for a fraction of the cost, and 3) designed to be reuseable, answers your other questions.
@@Myndale Zeno's paradox
That flight brought tears to my eyes as I was hanging off the edge of my seat... excited AF!! What a great surprise this morning of another video from you Marcus, thank you for that great summary of events! 😀
Just impressed by the whole work of SPACEX. They push the limits all the time.
they dont ..... NASA did all of this decates ago .... ilan musk is a clown
Great video, we got to see a great launch and progression of starship towards space travel. I love how you touched on and commented on each of the key points comparing to launch one. It really shows how much has improved for the better.
This was a pure joy to watch, I'm so excited for the next flight with all the data they will have collected from this attempt!
Both my 4 year old daughter and i were screaming and dancing at the TV when we saw the rocket launch fully then both screamed again when it separated was a great experience for her to be able to see history being made
Haha, very cool!
Congrats on the 500K buddy! I love your channel! Keep up the amazing work!
The IFT-2 is amazing!
Look forward to the next launch!!!
An interesting question which has also been posted on Twitter is that if you assume that the Starship dry mass is 150t (probably less) without payload, Booster dry mass is 200t (could well be, apparently the hot staging ring alone is 10t) and use fuel mass data from SpaceX's (even recently updated) website you get that the Booster with Starship on top should produce about 3km/s of delta-v, with 10% of fuel left for boostback and landing.
However, the velocity at MECO of around 5600km/h equates to only 1.56km/s which implies gravity losses of almost 1.5km/s!
Gravity over the 150 seconds of flight causes about 1.5km/s, but that's only if the vehicle were to go straight up, which it doesnt't. So why did they not achieve that delta-v and more importantly, how will they get 150t of payload into orbit if they used basically all the propellant for an empty Ship?
(btw, drag likely only accounts for less than 100m/s)
Data and calculations:
Ship: 150t dry mass / 1350t wet mass
Booster: 200t dry mass / 3600t wet mass / 540t at 10% fuel
--> full stack mass at start of Booster burn: 4950t
--> full stack mass at MECO (10% fuel in Booster): 1890t
Raptor sea-level ISP: 325s
standard gravity: 9.81m/s²
Booster Δv: 9.81*325*ln(4950/2890) m/s = 3070m/s
observed v at MECO: 5600km/h / 3.6 (m/s)/(km/h) = 1560m/s
--> observed losses: 3070m/s - 1560m/s = 1510m/s
stage-sep at 2:30min = 150sec
--> cumulative gravity loss: 150s * 9.81m/s² = 1470m/s
==> However, vehicle is mostly flying at an angle and therefore not experiencing the entire gravity loss
Rough estimate of actual gravity loss - don't quote me on that you would need to analyse the flight path, know the T/W ratio, angle, etc. along the entire path to calculate it:
about 75% of the theoretical gravity loss, which equates to: 1470m/s*0.75 = 1100m/s
This is almost 400m/s short of the observed deviation from the calculated Δv, which could in turn well be above 1.5km/s, maybe around 1.7km/s depending on Raptor ISP, remaining fuel in tanks, vehicle dry masses and so on
This is the best most educational video about starship on the web
Thanks Marcus
Best coverage in the world !!! Thank you.
Thanks Marcus!
Finally saw that the FTS on 2nd stage seem to have ignited, didn't notice it on live streams.
Even wonder if it was noticed by many SpaceX employees, since there was confusion on their live stream.
Also awesome you were on NSF!
It was such a good day! Loved all the hype-up coverage and it was a bonus seeing you on the NSF coverage too. It does me good to see all you experts out there working together to give people like me the experience of a lifetime. What did you think of SpaceX comparing the size of the full stack with Godzilla? I was laughing so hard :D Very curious to hear about the technical reports coming in the coming weeks, and especially hoping you were right that they could/should be ready to do a next text in a month. Thanks, Marcus!
Was spaceflightnow
Seriously? Hello! It's all been done before! And successfully News flash! In 1969 man walked on the moon On numerous occasions Been there, done that...😂
@@MOMO41837Grow up.
@momo41837 in 1969 we landed the equivalent of a golf cart on the moon just to be able to say we put our toes in the sand.
Starship will be more like landing a city bus or tractor trailer (depending on the variant) and is meant to colonize the moon, Mars and explore other distant parts of space.
1969 moon landings were amazing but the advancement in technology makes starship and SLS light-years ahead technology wise and capability wise.
@@caseygunter296 Right We've already fucked up this planet, let's go fuck some more up A perfect scenario would be a large asteroid hitting the earth and wiping out all life , keeping homo sapiens from fucking up and defiling othes planets You are, sad to say, part of the problem
Very nice work, Marcus!
And great progress for Spacex
Thank you, Marcus and crew!
Thank you for your commentary during yesterday's launch at LabPadre's Live stream👍🏻
Had been looking around for professional commentary amidst the numerous amateur streams. Yours made it all come alive👍🏻
The fact that it worked as well as it did for as long as it did is awesome. It was such a wildly successful test. I'm super curious about the state of the pad, myself. If it's mostly intact, it should really improve the launch cadence going forward.
Always such a delightful deluge of information spraying rapidly and happily to us... thank you Marcus
Thanks Marcus and crew
I'm impressed by the consistent improvements. Each new flight brings us closer to the orbit. And mind you this is the rocket that one day will be on its way to Mars. Few more years.
lol keep telling yourself that
@@RajpreetMatharu1993lol keep telling yourself it wont make it.
What an awesome day. I was fortunate to be there for this one. Watched from the roof of the Holliday Inn Resort. Marcus, you are awesome...
Great Launch with the Starship Successfully launched to Space!! Its a Shame Lots of Ignorant Television Reporters completely missed the Massive Accomplishments of this Launch!! Great Video Marcus!
Marcus, you do an amazing job recapping everything that happened! Thank you for working so hard my friend!
What an absolutely resounding success this launch was! Fantastic! So many firsts, so many milestones! History in the making! 👏👏👏👏👏👏🚀😍🚀😍
Hello beautiful, I have seen quite a handful of your comments on my post uploaded on my business page, so I decided to create a more private page to appreciate those people whose comments and good wishes encourage me and I hope to bring you guys more...thanks a lot.🚀
And the FAA must be appeased by the lack of peripheral fallout and the now-proven self destruction capability too. Hopefully the next launch is now an easier path through the glutinous red-tape-osphere.
The amount of damage to the pad on this launch compared to the last time is crazy, spacex is really improving a lot each and every launch test!
The amount of fire and brimstone here is just craaazy when you think of the scale of things.
Awesome Marcus. Was so excited for your vid. Great work mate 👍🏾
We are all witnessing the birth of humanity’s ride to mars. This is truly going to be a pivotal change in human history. I cannot believe i was lucky enough to be born at the right time to witness such profound history!!!
It's simply awesome and breathtaking by Spacex. It was one of the best things I have seen in my life, incredible. Slainte Marcus & teams for all you've hard work done throughout the years. 👍 ❤😢
Well done on getting this video out so quickly, Marcus. Great work as always.
What an event! I was screaming like a baby. Especially at that epic booster explosion!
I'm looking forward to seeing that explosion from other points of veiw.
Because every booster needs to explode once it’s done its job?
Okay, okay, it looked cool. Okay, you’re happy that it both worked well enough to get the second stage going, and gave you a spectacular show afterwards.
I still wish that it hadn’t exploded. Probably because I’m a cynical old man who prefers things to work properly. I’m so happy that Falcon 9 boosters almost always land properly (or fall into the ocean properly if a particular satellite requires that) instead of providing a cool-looking explosion. I guess I’m just a killjoy, and I should instead cheer like a little boy at a fireworks show when something big blows up.
@@markiangooleythe booster doesn't really need to explode but it did. For some reason I believe that aside from the booster having an anomaly, testing the flight termination system is important as it is one of the main issues of the first test flight. Everybody likes things to work properly hence the flight testing. SpaceX approach in achieving a working fully reusable booster and second stage is not the same as we used to with NASA. I believe the third test flight will be more amazing.
@@lytomagbato1688Wait until he catches the booster in the chopsticks. Even the haters will have to tip their hats.
The engineering and everything that led up to this lunch going as well as it did, is amazing!
The size,width & power, Thrusting its way, preparing to penetrate or atmosphere with no disregards! Only to be met with premature ej.. explosion!
At least the future humanity has at least one thing going for it!
Hi Marcus, Terrific video and commentary! Thanks so much for all of your hard work getting this together in such a short period of time. I always follow your channel to find out the best and most complete details of these events. SpaceX did come up on RUclips at approximately 20 minutes prior to the event. I was disappointed in them for not doing a commentary about this launch. They only came on long enough to show that the hot staging worked but didn't do any type of follow-up on Starship after the booster exploded. I am so glad that there are people like you and your team who get the most complete information out to us who are dedicating to SpaceX and these launches plus all other current space program information. YOU AND YOUR TEAM ARE THE BEST!
Thanks for this excellent review. I was surprised they didn’t do any kind of press conference, but it’s still SpaceX.
Theory: Right after the hot stage, you can see the booster velocity drop by 60-ish instantly, which may have caused the fuel to slosh forward, therefore causing engine relight issues.
Edit: The LOX levels on ship 25 dropped by a bit mid-flight, which could've been a leak.
I noticed the fuel dropping fast on ship 25 aswell during the live stream. certainly played a role if that data was accurate and explains why all the engines shut off almost simultaneously
@@eryck123 Any errors of slight leads to catastrophic failure. Unsafe for human travel. Starship is the Space Shuttle all over again. Cargo yes, Humans no.
@@corey3788 Oh. yes. It will take a lot of successful flights to get it human certified. And even then I would feel uncomfortable watching a crewed launch.
@@arctic_haze but thats just how you feel. logically speaking its better to sit in an thoroughly tested ship than in the ship with 1 succes and 0 fails.
@@anyanyyyyyy7689 Aren't we basically saying the same thing?
Marcus, your report is much better than the national news media! Congrats! Slava Ukraine!
It was a beautiful, clean launch. Not one Raptor engine failed. And Stage Separation was awesome. Enjoyed your guest commentary on Spaceflight Now during launch.
