This is a pretty big space advancement guys. Almost as big as Falcon Heavy.

Doesnt matter as long as they keep working toward it.

With the grid fins and the increased hydraulic fluid, I think there's a good chance they'll nail it on their upcoming attempt. Last one was close and they've already landed Grasshopper many times on land.

It looks like there is going to be an attempt on Monday 13th to be live streamed link below

http://livestream.com/spacex/events/395 ... _published

But it has very short launch window IIRC so might have a high chance of being delayed. But i wish them luck and intend to watch.

edited to add another link

http://www.theregister.co.uk/2015/04/10 ... e_station/

It has link to pdf with cargo manifest

At least we got a good Kaboom . . .

Well I think its a good sign that SpaceX has hit the drone barge twice in succession that is an achievement in its self. If they did not have the self imposed rules of a fully active landing as they want to land on Mars eventually. I suspect that with a suitable parachute or even just air bags(for a sea landing) they could retrieve the engines for reuse 9 times out of 10. But I think looking at the last two videos that they will get an successful active landing in the not too distant future.

My vote remains.. I still believe they'll succeed on their next try :)

Powered landing has several advantages over parachute. Precision most importantly, but it also means they don't need any extra hardware - just extra fuel. It's not much fuel either, since terminal velocity isn't terribly high and the almost empty first stage is pretty light.

Ditto on vote

& not sure if this an "official" or "unofficial" leak but more vid of the "landing" :wink: :twisted:

Cool vid, I think I watched it loop a dozen times.

I think a big part of the problem is the tough conditions under which they are trying to do something novel.

Supposedly now that SpaceX has proven that they can get the first stage down "in the ballpark" NASA and the USAF are going to let them try to do a landing on one of the old unused missile pads on the Cape next time.

Why not redirect some thrust through a Gyro at the center of gravity?

this way you can 'waste' some thrust, as well as stabilize your decent?

maybe a MHD and some added trace elements to the fuel?

That would add weight on assent. The F9 is already packing on the fat in pursuit of powered landing. Besides, then steering motor and surfaces would have to fight against the gyro.
