The satellites are moving at that speed too....

But they're not all moving at the same speed if the second stage was still firing between satellite releases.

True but irrelevant, as the second stage engine cut off before satellite deployment.

They're already insanely cheap compared to most competitors. This should take them to being ludicrously cheap.

Let's see who tries to imitate them and do a re-use, some real competition is what's needed next. Now for second stage re-use ;)

And then for the crew capsule reuse... oh wait :).

Seriously though, now I'm just waiting for updates on BFR / Mars mission development progress.

Really, 'classless'? The achievement is landing a space-capable booster vertically, after an actual mission above 100km, which can then be reused. And, Blue Origin managed that first, no two ways about it. I think it's probably pretty classless to imply that what Blue Origin managed to do was 'trivial'. Just because SpaceX is the current hacker's favourite, doesn't mean you have to downplay everyone else. I think Mus…

New Shepard is able to make several compromises that make landing _much_ easier. New Shepard doesn't have to get anywhere close to orbital velocity, so it can use a far less powerful engine. That means it can throttle down far enough to hover. That is a _huge_ advantage over Falcon 9, which must time the landing burn perfectly to hit 0 velocity at the exact moment it touches the ground. They're in the same club like…

I guess it's like Hilary and Tenzing being the first to climb Everest, and then someone else (can't remember who it was) coming along and doing it without supplementary oxygen. Just because that was harder doesn't detract from the fact that Hilary and Tenzing were first and anyone else is just joining the ever-growing club of Everest summiters.

Now, if you want to invent an extra category of 'first VTOL landing for a first stage booster for an orbital rocket system that uses boost-back to change trajectory mid-course' or similar, they SpaceX are first with that, and of course it's an awesome achievement.

Youtube link for people for whom livestream videos won't work. (I believe the embedded player is livestream). https://www.youtube.com/watch?v=O5bTbVbe4e4

Thanks! Got a link to the replay for those of us tuning in late?

If you look carefully at the YouTube live streams, you'll notice you can scroll them back all the way to the beginning - the "live" part is always at the very end :).

EDIT: and here's just the landing itself: http://www.gfycat.com/WeepyCelebratedAfricanaugurbuzzard.

"Welcome to the club"? Wow, that was classless. What Blue Origin did was impressive, but it was utterly trivial compared to what just happened with this flight.

"what the rest of the system does has no real part to play in the landing of the rocket stage"

That assertion is ridiculous. The rocket is optimized to do one thing, push it's payload into orbit, this is a very strict restriction, especially on a two stage rocket. On the other hand, the designer of a suborbital vehicle has ample design space to play.

It's like comparing your practice free throw, in your back yard, with a slam-dunk in the NBA.

I join in congratulating SpaceX for this awesome achievement. It's like, holy fuck, they landed the rocket AND deployed 11 satellites, all in a single Pomodoro! I also want to commend them for a few minor things: - a real-time stream from landing (as opposed to holding it and releasing footage few days later, as before) - a real-time stream from satellite deployment, with a camera placed so that we could see everythi…

Agreed. Loved the data feed on the video. The tension built up as the indicatior neared the "landing" hash mark.

Interesting - something flaming separated from the first stage as it landed. You can see it separate, hit the ground, and burn as the landing completes. https://youtu.be/O5bTbVbe4e4?t=2518

I don't see what you're seeing. There are lights surrounding the landing pad. Are you talking about those?
