finally, this thread doesn't suck anymore. You nerds had been boring me for a week with this!

:colbert:

so what was the goal of this launch beyond the satellite? Successfully landing the first stage, intact?
 
hmm

Successful @SpaceX rocket landing on a barge in the ocean! Big step forward in rocket reusability and lower cost access to space!

Going by the Orlando radio. They said @SpaceX landing successful. Waiting to hear more...

Wow was it already near geostationary orbit when it released that satellite? That seemed fast. Or does the sattelite actually have enough thrust to get itself there?

No, this was evidently a much higher orbit so there won't be much fuel for the attempted landing. They are going to give it a shot but they are expecting a failed attempt at landing on the drone barge. I say good for them for giving it a go despite probable failure, can't be cheap.
 
problem with space access being private, were so use to NASA showing everything. Should be in the agreement for licence to allow real time video of launch and landing. Soon when Space X moves to TX even launches will be private.

well it looks like they just landed something on the barge, no? Isn't that the first stage, and the point of this design?
 
Oh right, are they going to try to land the second stage too?

What normally happens traditionally, do stages just end up as space junk or do they eventually get deorbited and burn up?

They said it would take weeks for the satellite to get into position and setup. I don't know if it's carried by momentum or it will provide its own thrust (would seem silly but I'm not a rocket scientist) or maybe they were talking about minor course changes to get into the correct geostationary orbit.

From what (little) I understand, the 2nd stage has an engine designed to work in the vacuum of space so I don't think they could land it even if it could survive reentry. Besides, it's just one engine so I doubt it would be all that cost effective. Pretty sure it burns up in the atmosphere but I'm sure someone here will have a more definitive answer.

If they even came close to landing it on the barge it would be a huge success. If they stuck the landing it would be absolutely great.

And yes that is the point of this design but because of the much much higher than normal orbit they have rather tight fuel limitations to attempt the landing. Basically no one is expecting the first stage to land this time because of the high geostationary orbit but it's still great practice for the more common LEO launches. I'm sure once they figure out how to land the first stage from LEO they will eventually get the higher launches down pat, it's just absurdly more difficult and they are still in the learning phase.

I really really hope they stuck the landing but I'm not holding my breath until I see something official.

Well it was also a three engine landing (normally they use one engine which is still more than enough power).

When using three engines it means they have to be coming in very fast, they save a bit of fuel this way, but since the engines don't have a very granular throttle control, they get very close and do what's called a "hoverslam". It was highly unlikely this would work on the first try anyway.

The fact they got close enough to the barge to attempt a landing is pretty good to be honest.
