+fortyninepages That stage was a throwaway - it had already delivered a satellite into orbit. The landing attempt was an experiment.

If only we could replace Elon and his team of rocket scientists and engineers with the youtube commenters on this video, this landing would have been realized years ago using either a huge tube that would suck the rocket in, an enormous net that would stop the rocket mid flight or, my personal favorite, a giant baseball glove that would catch it as it falls.
Pongthep Wu It is possible, but there wouldn't be a lot of benefit over the current grid fin design. Those provide a lot more drag than you might expect when used as a control surface.
Boyd Smith It went boom during landing, not launch. SpaceX's customer - NASA - is pleased, as Dragon is flying to ISS as we speak, safe and sound. What happens to stage after stage separation is no issue for payload.
Joseph Smarr who doesnt wanna see rockets exploding? hes getting massive press everytime is crashes, and they'll probably have it figured out before it gets old
SpaceX that some true ROCKET SCIENCE GUYS! Awesome! Incredible! Next one is a keeper for sure! What a boom! YESSS! - edit- guys, im not joking here, or just enjoying the explosion. This is actually true rocket science and explosions like this is how you learn and get it right. This is how its done. getting a whole rocket back from the sky and making it get to a target with precision - is a huge success. Not a failure.
Did anyone else feel a surge of affection for the booster as it fired those top-end side thrusters in a last desperate attempt to hold attitude? Man, that's really quite emotional :-}
***** SpaceX utilizes an elite team of retired Navy Dolphins to collect the debris. It's much cleaner than the current system of atmospheric vaporization.
I like that you can really see the thought process of the pilot: 0:06 - Little to far on the left... no big problem, I can do that... 0:09 - Yes, told you 0:13 - Oh F*ck, OH F*CK! RCS ON FULL POWER, GO, GO! 0:17 - Oh sh*t I'm gonne lose my Job... 0:20 - Ok... I am going home, I quit!
Yeah there it went. Blows my mind that for the last half century the huge majority of first stage boosters have just been dumped into the ocean never to be recovered. Awesome that Spacex is developing something like this especially with the way they are doing it. On actual missions. So if it fails is like, "Oh well, we would have just dunked it on the ocean otherwise." That way there is never a monetary loss. :D
Stewkers Solid rocket boosters were always recovered from the ocean actually. They would let them fall safely using parachutes and would then send ships to tug them back to the shore for reuse. The point SpaceX is trying to make by landing on the barge is to show that it is possible to land the first stage successfully back on the earth only using engines and without parachutes so that in the future they will be able to redirect the first stage back to the launch pad.
The Lorentz Factor Also saltwater corrodes the fuck out of rocket bootsers, making it ridiculously expensive to reuse. SpaceX version would be unprecedently cheap.
***** Ступень для экономии. Планируется использовать одну ступень на десять запусков. На парашюте её спустить невозможно - если бы ты хотя бы раз спускался на парашюте - знал бы о скоростях такого спуска, весе парашюта и что происходит с ним после приземления.
Simon Als Nielsen Even at minimum thrust the vehicle has a TWR of 1.8, which means in the few seconds we see it it's going from 100mph to a dead stop on the barge.
So very close! This is an amazing feat you've been able to accomplish so far, in my opinion, and it will be even more amazing to me when you can pull this off successfully. Keep up the good work!
Именно такие люди меняют весь облик человечества! Приятно знать, что где-то на Земле есть люди, объеденные мечтой, идущие к своей цели, невзирая на неудачи. С нетерпением ждем, что бы увидеть хоть на экране, как все человечество делает огромный шаг на встречу будущему! Терпения всей команде SpaceX, побольше отличных революционных идей, и конечно же, удачи!
This is the single most awesome thing I've seen this year. This one video probably represents the most important thing that has happened technologically this year (that's until you land successfully, if that happens this year).
As a citizen who is conscious of the incalculable benefit of reusable fuselages, I have been tracking this project since its inception. The progress that you amazing individuals have accomplished leaves me giddy to see what you have planed for the next ten years. F#(%ing amazing job y'all! I can't wait to watch the first successful live stream!!!
I appreciate SpaceX to take the time and upload this. This is progress, not failure. I have blown up many of my crafts in KSP before I can even make it do barrel rolls.
Very little new technology like this works perfectly the first few times. I have no doubt they'll get it sorted. BTW: apart from safety; is there a reason for landing on a barge at sea? Surely the movement of the barge just complicates the landing? Or is that one of the reasons for doing it?
No, there isn't, except for being further down range and therefore reducing the amount of fuel needed in the boostback burn. The barge doesn't soften the landing, it is too heavy to be affected by the light rocket. (It won't get "pushed" into the water)
Joan Evans One, it has to do with trajectory. Rockets don't just go up, they go laterally as well, because "orbiting", in simple terms, is really just moving forward so fast that you miss the ground as you fall. Thus, at stage separation, the first stage is no longer over the launch site. It's arcing over the ocean. It would take a lot more fuel to turn it around and send it back to the launch site, and launching with the trajectory over the ocean has many, many benefits, one of which is the second reason for landing on the ocean. That second reason is safety. There's not a lot of shit to blow up in the ocean. So, if someone messes up, or something goes horribly wrong, you splash down instead of making some random city have a *really bad day*.
Despite this attempt not working, it's still amazing that they are able to even attempt this. Landing on a barge with a parachute in of itself is ludicrously difficult but to attempt it vertically with boosters is almost completely insane! My (proverbial) hat is off to the engineers, programmers and everyone else involved in the making of this at SpaceX, I'm sure you'll get it on the next attempt. If not, then don't give up!
It must have been windy.... It's amazing it came in controlled right to where it belonged and it failed in the last seconds. It did look like it was moving faster than grasshopper did just before touch down. I hope they stick the next one.
Ariel Lezen The Merlin engines can only throttle down to ~70%. As it stands, when landing the first stage only has the center merlin lit, and at 70% thrust, which is still far too much thrust for a near empty rocket. At launch, 90%(or so) of the first stage is fuel, and fuel is heavy. When it's landing, most of that fuel is gone so it's very light. They can't throttle the engine down low enough to reach a TWR(thrust to weight ratio) of ~1 which would allow the first stage to hover. Edit: I forgot to mention that 1 Merlin(just the engine) has a TWR of 150, these engines pack a punch!
Ariel LezenEven on one engine throttled, thrust is more than the weight of the almost-empty stage. So it has to come in 'hot', then the onboard guidance plays with the throttle to reach 0 altitude right before 0 velocity. Elon tweeted earlier that it was like playing the old Lunar Lander game, but at 6X the gravity (and with limited throttling.)
+triforcelink Rocket science. Mostly the fact that if there's any amount of fuel left over, it'll want to burn in the heat created by the engine. As it burns, it expands rapidly, creating an explosion.
Honestly, it is easy to see how much an advancement in technology this simple fail already is once you see the jets fire at the top of the rocket. Good job Elon! Keep truckin!
DjDialogic Also, a more predictive gyro programming, especially for the top jets...but then again all of that could be mitigated by an extra 100 meters of slower controled decent.
+DjDialogic Problem is, they have to come in fast to save fuel. If they burn longer they run out of fuel. This is like...the hardest controls problem in the universe.
Intamin Makes sense but I expect that a size increase to accommodate additional fuel for the last seconds of reentry would pay out in it's ability to respond and immediately adjust to last second variables. I wonder if there is a platform scan and data transmission to the for adjustment. That would be cool.
+DjDialogic I'm not sure how they do the controls. I'm sure is largely GPS, but ground based visuals might help, as well, for landing. I think they have the speed just fine, here, they just need more responsive controls and they'll get it. Everything I saw here was either delayed a split second, engaged for too long by a split second, or overshot a bit. They're super close! Exciting.
i have to give mad props, for this is the 2nd attempt and for all intentional proposes they made the pad, im looking forward to the 3rd, they have it in the bag.
They’re getting better at it! They got more of their rocket back this time. Before any flamers react badly to my comment, I admire SpaceX for aiming high - they are trying something that no one else has and first-timers rarely get it right the first, or second, time. It wasn’t that long ago that NASA was failing more than it succeeded - check how many Ranger Moon missions failed before they got it right. The point is, you never give up.
looks like they could slow the descent a bit sooner and give some time to hover for a bit and line things up. before final. The Grasshopper tests showed the slower descent and hover prior to touchdown so maybe a bit of tweaking on the descent profile or its possibly an issue with the landing platform altitude detection. Its going to be difficult to get it right but the at sea tests are probably the near worst case for success.
bitter bal The F9 was making some rather severe corrections at low altitude. It does seem to lack the precision of the Grasshopper. It will be fun watching them sort this out.
bitter bal there's a big difference between a Falcon 9 falling at a high velocity than just flying it for a few meters and bringing it down. The difficulty level is multiplied by factor of 100 maybe.
Какая красота, как наглядное пособие по движению с изменяемым вектором тяги. Видно как ракета наклонилась против ветра для компенсации, но у земли переборщила. Возможно у поверхности эффект экрана увеличил тягу и ракета проскользила дальше. Понятно, что успешные посадки - лишь дело техники. Возможно добавят боковых импульсных двигателей сверху, для удержания после посадки. Это чудо техники ещё изменит историю полётов в космос. Маск молодец.
Well I hope the ones you’re talking about aren’t saying they’re “smarter”. We are armchair rocket scientists, and we know we wouldn’t be able to launch a rocket to orbit based off of our experience. But we still do have a very good knowledge of rockets:)
I was really rooting for that valiant RCS thruster to snatch victory from the jaws of defeat, but alas it was not to be.
Scott Manley it sure was trying.
Scott Manley can you show them how to this on KSP
Scott Manley It reminded me of your attempt, I think it was #6. Definitely needs more reaction wheels.
***** It needs more struts too.
Haha, those were my exact thoughts! The little thrusters that could(n't).
I admire the poor thrust vector, it tried its best to keep it straight. :(
+WiseSloth ForBernieSanders Push..! PUUUSH!!!!! :(
+WiseSloth ForBernieSanders Thrust vector?
Clearly it was a reverse bushing compensator malfunction. In addition to the dual apex manifold and the cybernetic discharge stabilizers being misaligned.
+Jay Starr
The problem was corrected using a turbo-encabulator...
+fortyninepages I admire the idiots who don't trust the free market.
+fortyninepages That stage was a throwaway - it had already delivered a satellite into orbit. The landing attempt was an experiment. Nobody lost a dime, except for SpaceX needing to do a bit of barge repair. And you ought to be glad the public sector is buying launches from SpaceX - every dollar spent there means that five dollars don't get spent at ULA instead. As for safety, there was nobody on that stage, nobody on the drone ship, and nobody on the drone that was taking the video. So calm down.
No more worries my friends, they've fucking made it!
OMG, this comment got 209 likes, without any reply (until this reply)!
jajaja true
that is why you have to swear
If only we could replace Elon and his team of rocket scientists and engineers with the youtube commenters on this video, this landing would have been realized years ago using either a huge tube that would suck the rocket in, an enormous net that would stop the rocket mid flight or, my personal favorite, a giant baseball glove that would catch it as it falls.
+Andrej Đukić Also, a watertight bag that somehow wraps itself around the rocket, followed by a parachute deployment.
+Andrej Đukić I really wonder though, if it is possible for the Rocket to maneuver through the use of flaps much like an aircraft wing or missile.
Pongthep Wu It is possible, but there wouldn't be a lot of benefit over the current grid fin design. Those provide a lot more drag than you might expect when used as a control surface.
+Andrej Đukić But there are millions of us commenters though. We can't all be idiots. Just look at my profile pic for crying out loud.
Ambient Morality actually After watching the successful landing, they seem to already be using some type of flaps .
Wow, amazing footage. I'm grateful that Elon Musk is being so transparent with the results of these historic attempts!
Rocket stage go boom. :(
***** totally agree, but it's still admirable to share your failures publicly IMO.
Boyd Smith It went boom during landing, not launch. SpaceX's customer - NASA - is pleased, as Dragon is flying to ISS as we speak, safe and sound. What happens to stage after stage separation is no issue for payload.
Joseph Smarr Because Elon doesn't give a fuck about what the haters think.
Joseph Smarr who doesnt wanna see rockets exploding? hes getting massive press everytime is crashes, and they'll probably have it figured out before it gets old
It almost landed!!
...imagine THAT!
No heroic RCS-compensation, no dramatic fail, no EXPLOSION...
Whew, that was close.
I bet YOU were WISHING for it to land incorrectly
Danny2462 Clearly needs more SRBs in the future
Danny2462 A Kerbal would know.
Danny2462 A Kerbal would know.
It finally works, I come from the future :v
If SpaceX got $1 for every person asking "Why not parachutes?" they'd already be able to fully fund their Mars missions.
@@Royal_Respects
Parachutes ain't gonna do much good for a thing that heavy.
Why not parachutes?
@@mountaindew50 Parachutes can't slow it down enough to land on a surface without problems.
Elon wants to land his rockets with style. I can't blame him though. Seeing those two falcon boosters land simultaneously is simply amazing.
because kids think that parachutes can hold any object no matter the mass
This shows how there are always going to be failures in the way of success
Stop trying to be deep
yeah man
+BRVvideos Your right.
Its true friend, as for now in a span of 4 weeks, they have successfully landed 2 missions.
+BRVvideos And there are some failures without a hope of success, Like Bernie Sanders .. Poor old guy :/

Watching this video now after what was achieved today is quite humbling.
Today was another launch. I'm still watching every live stream whenever I can!
@@Paretozen And today, another launch has been done too.
And today they gon be sending 60 satellites in orbit at once
Here when they landed a mini-starship (starhopper)
@Hoyt Volker ..and NOW? Hello Starhopper!
The little RCS port that couldn't :(
Even a crash landing is a landing!
So very close!

I love that SpaceX is publishing their blunders as much as their successes rather than trying to hide them.
Well if they never uploaded the landing and people would get suspicious and come up with all these extremely wild theories.

Oh my kod. This is epic!
Thank you, Space X, for sharing your successes and failures with the world. You guys continue to blaze a new trail in the future of exploration.
I like that you can really see the thought process of the pilot:
0:06 - Little to far on the left... no big problem, I can do that...
0:09 - Yes, told you
0:13 - Oh F*ck, OH F*CK! RCS ON FULL POWER, GO, GO!
0:17 - Oh sh*t I'm gonne lose my Job...
0:20 - Ok... I am going home, I quit!
this wasn't a manned rocket. There were no pilot...
Nerds United I mean the guy in the control room who "pilotet" the rocket
TheLukrie™ oh
It's all done by software. The rocket has no one in control.
Zack Pio Oh... well I guess I learned something new ^^
Someone forgot to install MechJeb
Dino Sabanovic Landertrons! Much more reliable than MechJeb, if you like suicide burns.
And put lateral RCS thrusters to help out with stability and attitude correction.
Dino Sabanovic hahhhahahahahahah :) nouch.. have installed mechjeb.. but v1.0.. hahahaha
So they actually land it like in Kerbal Space Program?
Rafa1589 You land in Kerbal Space Program? Hmm... Never thought of that :D
Rafa1589
Also did the same thing Mechjeb will sometimes do.
Rafa1589 it didn't hit the ground at mach 3 so no.
Rafa1589 That was about how it went for me the first few times I tried to land on the Mun.
***** Until it blew up.
That one little thruster at 0:09 "I think I can, I think I can, I think I can- AWWW SHIIIIIII-!"
And booomm there goes several million dollars....

So very close! This is an amazing feat you've been able to accomplish so far, in my opinion, and it will be even more amazing to me when you can pull this off successfully. Keep up the good work!
I watched the ISS and the Spacex cargo ship catching up from behind last night. I was on my deck and the sky was clear --It was AWESOME!
i love how open SpaceX is about their failures. this is science and each failure is an important learning experience.
So awesome!
Trying to land a massive 11-STORY tall first stage on a relatively small barge with pin point accuracy in the middle of the ocean is VERY HARD to do.
That's why we got a robotic A.I to do it!
@Anant Tiwari never said it was a piece of cake... I just implied that using A.I. significantly increases the chance of success...
what youve done so far is amazing!!! Good luck next time
It may not have ended well, but rockets landing on their own was still science fiction until not too long ago. It's still amazing to see.
So close! I bet you guys can get it next time! Couple tweaks.
Congratulations. I watched as it happened and i nearly took flight myself as i nearly hit the ceiling with joy :)
You can see that RCS thruster at the top trying like hell to to straighten the thing out. This is incredibly close. Awesome work SpaceX!

The little RCS thruster that couldnt.
Awesome landing!
This is one of the coolest things I've ever seen. I can't freakin believe how close they are to getting it done.
Practice makes perfect! :)
Awesome. So close, RCS wasn't enough… you need some SAS from KSP ;)
almost got it... can't wait to see a perfect landing!
You are getting there SpaceX. Much better than the last one.
when you forget to change "Orbit" instead of "Surface" on the NavBall.
But will it blend?
Reminds me of those space games I always lost at. Had the same feeling.
Despite this attempt not working, it's still amazing that they are able to even attempt this. Landing on a barge with a parachute in of itself is ludicrously difficult but to attempt it vertically with boosters is almost completely insane!

Шикарно вышло..Выглядит, как обратная съемка.
Why do they always have to explode after falling over?
+triforcelink Rocket science.
Mostly the fact that if there's any amount of fuel left over, it'll want to burn in the heat created by the engine. As it burns, it expands rapidly, creating an explosion.
+triforcelink For dramatic effect.
Dude it’s like 70 meters tall

You will succeed! I believe in you! Good luck!

The thruster that couldn't
Was rooting for that baby top thruster, tried so hard :( 0:09
i have to give mad props, for this is the 2nd attempt and for all intentional proposes they made the pad, im looking forward to the 3rd, they have it in the bag.
They’re getting better at it! They got more of their rocket back this time.
Before any flamers react badly to my comment, I admire SpaceX for aiming high - they are trying something that no one else has and first-timers rarely get it right the first, or second, time.
It wasn’t that long ago that NASA was failing more than it succeeded - check how many Ranger Moon missions failed before they got it right.
The point is, you never give up.
There is a thin line between landing and impact.
Third try is the charm. Are any betting websites taking bets?
Nice, I'll play this over and over again as I try to solve magnetism.
That last RCS thruster was not going down without a fight. Press F to pay respects to the thruster

You don't fool me! It's just a rocket launch video backwards.
+Gabriel cox I agree!, It was also a rocket magically formed in a fireball, this is a great achievement indeed!

Elon is surely a magician. He could create a rocket from a smoke and fireball. Hahahahah those idiots have no bounderies
looks like they could slow the descent a bit sooner and give some time to hover for a bit and line things up. before final. The Grasshopper tests showed the slower descent and hover prior to touchdown so maybe a bit of tweaking on the descent profile or its possibly an issue with the landing platform altitude detection. Its going to be difficult to get it right but the at sea tests are probably the near worst case for success.
The Grasshopper can hover, but the F9 can't.
bitter bal The F9 was making some rather severe corrections at low altitude. It does seem to lack the precision of the Grasshopper. It will be fun watching them sort this out.
bitter bal there's a big difference between a Falcon 9 falling at a high velocity than just flying it for a few meters and bringing it down. The difficulty level is multiplied by factor of 100 maybe.
Exactly.
Какая красота, как наглядное пособие по движению с изменяемым вектором тяги.
Видно как ракета наклонилась против ветра для компенсации, но у земли переборщила. Возможно у поверхности эффект экрана увеличил тягу и ракета проскользила дальше. Понятно, что успешные посадки - лишь дело техники.
Возможно добавят боковых импульсных двигателей сверху, для удержания после посадки.
Это чудо техники ещё изменит историю полётов в космос. Маск молодец.
Your almost there Mr.Musk a true revolutionary for our time. Some may say the new jobs?? Keep it up! Never stop!
It's amusing to see all these TH-cam users who think they are smarter than Elon. I got news for you, if you've thought of it, Elon has thought of it.
Matthew Singer Dan Roganti He's laughing at you bro
Well I hope the ones you’re talking about aren’t saying they’re “smarter”. We are armchair rocket scientists, and we know we wouldn’t be able to launch a rocket to orbit based off of our experience. But we still do have a very good knowledge of rockets:)
Too close.. Next time!
I know you will get it someday spacex, real soon, and when you do, it will be amazing, hell it's amazing we got this far
That shockwave though, could watch a few more of those. Time to watch "Destroyed in seconds."
