0:36 That exhaust is so beautiful...
And now here we are with the Falcon Heavy.
thank goodness for SpaceX you guys are doing good work
You guys keep getting better and better. Congratulations Spacex folk.
Thank you Elon Musk for not selling your brilliance to the Military Industrial Complex. Youre the only guy doing ANYTHING to help humanity break out of this prison.
This was a triumph. I'm making a note here: HUGE SUCCESS.
Not many people are changing the world right now, good to see someone actually doing so.
Wow the patterns generated at 2:46 are mesmerizing.
Every time I watch Space X stuff, I immediately hop on Kerbal SP to celebrate rocket science.
Well done guys!
Dear SpaceX.
Great job as usual. please give us more footage of the first stage restart next time.
Thank!
Air resistance is a powerful thing. The terminal velocity is minuscule compared to how fast the first stage gets the rocket going by separation. Plus the first stage is probably less than a 20th its starting weight, let alone the extra weight of the second stage and payload. Less weight = less momentum = less energy to slow it down.
When a First Stage returns to launch site it will be an eye opener. When a returned stage flys a second time everything will change.
I'm hearing from SpaceX sources that the stage executed a successful braking burn (shown in video) and that the stage survived to start the secondary burn before hitting the water intact. Looks like SpaceX is close to making this work.
2:48 was showing the first stage relighting for possible recovery - that's the goal behind SpaceX's Grasshopper tests. So it does make sense for it to be at a lower altitude than the second stage.
SpaceX.....All you guys working there - you are my Heroes!
And just think they can do this while still in development with the Raptor engines. This is amazing, but we haven't even seen the big leagues yet!
The first stage separation speed is over 6 times the speed of sound... parachutes would burn and shred at those speeds. So they use the engines to slow the stage down for reentry.
The green stuff as the engine lights up is the TEA chemical igniter they use to get the engines started.
They didn't get close to a power assist landing, they only slowed the approach until the fuel inside the tank started sloshing causing the craft to wobble out of control which caused the engines to shut down for lack of fuel and the vehicle to crash at a very high speed into the ocean. The good news is that they were able to bring it back into the atmosphere without burning up. That's a step in the right direction.
To be optimistic still, taking this as a reminder that no one is above making mistakes would be wiser than condemning the whole manpower behind it.
Yeah, wanted to see if there was footage of the actual steps they managed to take. Didn't know how far they descended under power, before the sloshing. All credit to them for even attempting it :)
If I recall correctly, even with parachutes they'd still need the rockets to reduce speed enough to land. In addition, I think I read that tests showed that parachutes impart way too much stress on the rocket itself to be useful; no point in trying to save rockets that will snap in half when the chutes open up.
You guys are the reason I'm going to study Aerospace Engineering. Well, and kerbals, but you're a real inspiration. :)
To me (just based on this video), it seems like the first stage retro burn caused the camera to get sooty quite fast... Maybe they'll be able to fix or remedy that somehow before the next time, but I guess this is all the useful footage they got from this try.
Cool to see the first stage re-light
On SpaceX website it lists capabilities. Falcon 9 cost $56.5 million, payload to LEO 13,150kg. $56.5m/13150kg = $4296.56. The $4,109 per kg for low earth orbit was from a press release, but you do the math from the info on the SpaceX site your self.
well done spaceX another great accomplishement
Great job SpaceX! Let's see the next F9R get to a stable hover.
Good thing we'll soon have Mars as a spare world, thanks to SpaceX.
From my understanding, the parachutes can only slow the stage down so much and can't direct the stage to a certain site. The stage would still be damaged and it would take extensive repairs to fix it. With this system, stages become much more reusable and thus cost less money over the span of use.
At 3 min you can see stage 1 relit but spinning. I think they said the spin starved out the engines after that. Maybe they can toss on a drogue chute that can be cut free after the rocket is stabilized. I think armadilo aerospace has an inflatable that looks like it would work.
They are the same age a lot of the guys who worked on Apollo were at the time. If this continues think of the experience they are accumulating for the future. They're just getting started too. Pretty wild, huh?
Man I love you guys at space x. I love the videos much.
Congrats SpaceX!
I think it was just a test to see whether or not their current engine configuration could relight for when reusability upgrades are made.
This video is soooo much better than the original one released on launch day... what ever happened to the first stage though? was the second burn simply to reduce re-entry speed?
Shotwell just reported that the stage was fully intact 3 meters from the ocean surface. They are very close people!
No, the technology isn't quite there yet. Look on UA-cam for Grasshopper tests and you can see where SpaceX are in the development test program.
They are well along, but haven't even finished the demonstrator test program yet. A long way to go, but they are well along the way.
Shame the camera got covered in something on the first stage reginition, still best of luck with the next launch, youll get there eventually.
The world's largest self-propelled phallic symbol! :-)*
Seriously, the lack of vibration in the video was impressive. They seem to have a smooth-running machine.
The secondary mission was to test reignition of the first stage. Several factors can make it difficult to calculate reentry of a 24 story object... they went with good old fashioned fly and try-again method.
NASA itself has proven that reusing a space craft is much more tedious, and nowhere near as cost affective than using a disposable rocket. Just look at any of the space shuttle missions. It use to cost about 500 million dollars (rough average) just to repair the shuttle after a mission. It costs about 25 million dollars to make a disposable rocket that can put a satellite equivalent to what the space shuttle could into orbit. And as for a rocket landing where it launched, it would only do damage
"PROP AVI GNC move to section 10.59 - GC move to section 10.58 - GC is in 10.58"
It wouldn't be a SpaceX launch without this sentence!
Orbcomm OG2 Flight 2 didn't have that. It seems they ditched 10.59/58 for F9FT launches.
All of SpaceX launches have them, however they don't always aire them.
THAT WOULD BE AWESOME!
Eventually was the altitude skewed a little because the added distance of how far down range the rocket was from the launch area? Hard to believe that 60 miles on earth is the displacement from Atlanta to Athens and at 2:26 is the distance the rocket is above the earth.
The next 2 flights will not have first stage reentry. The next try will be on CRS 3 early next year. They may try to land the stage back to KSC depending on agreement with NASA.
Yeah wasn't expecting the full on landing attempt with legs etc. Just wondered if there'd be any footage of the engines firing which caused the sloshing of fuel and the crash.
They attempted a soft slashdown into the ocean (as a test for a landing on hard ground). They were somewhat successful. The first stage relit to slowdown, but then something went wrong and the stage began to spin. This centrifuged the fuel and choked the engines. Hopefully they'll have it figured out next time!
I will work for you guys one day, I swear it!
It seems to me like Spacex is more interested in retrieving the engines support structure than they are in getting back a full first stage.
Can't wait for falcon heavy!!!!!!
Not sure why people downvoted your comment. It's a fair point. We wouldn't even have modern rocketry without the space race "between the soviets and the americans" , or however you want me to put it. I agree with your comment.
Это прекрасно. Сразу появляется некая гордость за нашу, уже кстати Межзвездную, цивилизацию.
Space X, woot woot!
Km/h is not the same as m/s. There's a conversion factor of 3.6 hidden somewhere. Still, the orbital speed for Earth is about 7800 m/s or approximately 28000 km/h.
Did anyone else hear Apple's Siri say "Good telemetry, good power health!" at around 1:12?
1:12
Man that was so cool!
Not a stupid question they do use parachutes if you look at the current top comment you see "When a First Stage returns to launch site " the reality is we can retrieve the first stage but you must understand what they just went through all that heat he doesn't say we can not retrieve it he says if it returns to the launch site same scenario with 2nd stage.
Cant wait to see Falcon Heavy!
so did the first stage do a test water landing, or did they just test if they could relight the engine?
anyway awesome launch!!!
Dude. Its the sound of the engine/flames
While Goddard showed some basic plans to the press, he avoided publishing most of his work for exactly this reason.
While Goddard was certainly inspirational to the germans, the A-4/V-2 rocket series diverged significantly from goddard's work, with completely different propellant combinations.
The one thing that they did have in common, Goddard's significant contribution, was the use of turbopumps to feed fuel into the engine. However this is used by every large liquid fuel rocket ever made.
Awesome, want to see more post-separation first stage footage and details!
You know, in some obscure way, he's right in part. If it wasn't for the Soviets, the US wouldn't have been pressured to develop the ability to put stuff into orbit in the first place.
Not that I agree with him in this specific case - this launch was all private enterprise.
Orbital is catching up on the cargo biz, and yes...they have been in the satellite market a lot longer than Space X. However, Space X still remains the only company with a cargo vessel than can return to Earth. As far as I know, no one else in the world has one. They all use disposable throw away cargo ships and the crewed ships can only return minute amounts of cargo.
That was so amazing when I saw that
That's really amazing for mankind.
Of course she does.
at 3:23 Falcon is doing 25,961 km/h at 1022 km altitude, but it only needs 2039 km/h for a stable circular orbit. Why is it still going 10x faster than orbital speed?
orbital speed=√(GM/(6376000-Altitude)).
The earth's surface rotates with 1668 km/h.
That raw power, Awe inspiring!
Fascinating!
I don't think sloshing was the reason, it would be easier to keep a nice angle with the landing gear acting as a stabilizer
I can't wait to see a Grasshopper version of this !
they're just teasing us a bit! ;)
People keep forgetting bout orbital science, they are doing just as well as space x
Here's an example to prove my point:
You live in a small fishing village with only a handful of fisherman. Despite it being small, there is a free market surrounding selling the fish. One day there's a bad storm and all the fishermen die except the one who stayed home sick, He now finds that he has a monopoly on selling fish in his village- he's the only one left with a fishing boat.
Is the market still free? It's still exactly the same market. Nothing has changed except the number of entrants.
KERBAL ON A GO !!!
1:12 GladOS works for them!
Awesome as always. Go Space X!
You seem like a credible source of information
I will look it up for you, no problemo) By the way what do you do in real life, software developer?
Damn thats rad
Mighty impressive! Well done!
do you know any other reliable and affordable shuttles?? btw, shuttle played the major role in building ISS. it was a great vehicle... btw, 1.6bln is nothing compared to the budget of defense dept. which is $800bln/year
you guys freaking rock
NASA has been by far their biggest contract. More than half the money they received (including from investors) has come from contracts with NASA.
I think it failed as the fuel centrifuged out and starved the engine. That might have been a different flight though.
and a Kerbal was successfully launched!
Great job!
amazing
Really nice!!
Ok thank you for answer.
Wow great job Spacex hope to see more of your great work.Im amazed at the conservative look of the launch vehicle and launch pad ,well done.I really am looking forward to seeing the first stage assemblies return to ground state.
go spaceX!
I don't understand how they will carry enough fuel to decelerate and land the first stage. The payload to launch weight ratio is already in the low single digits of a percent, so where is the margin for more fuel? Do they just build an enormous rocket burning multiple times the fuel other rockets do for the same payload?
I know, I know, I was joking... The Falcon 9 rocket is a massive achievement.
Nice! Could you include the downrange in that info box?
It took evolution for this to happen
I wish I could use this rocket to send me to orbit...
Точно, выехал!
