Holy shit. We're getting there. Slowly but steadily.

Re: SpaceX's Grasshopper

SpaceX continues to reinvent the wheel, with spectacular results. Seems they're a little more than halfway to where the DC-X was when it was cancelled, which -- this being SpaceX -- probably puts them two to three years away from an operational test flight.

It's a great flight! I can't wait to see them do an "end over end" maneuver.

Lands the way God and Robert Heinlein intended.

That's taller than DC-X ever was, right?

We should build one of these, just for fun.

Re: SpaceX's Grasshopper

Today GrassHopper made its final(?) and perhaps dramatic flight, to a height 744 meters - although the amazing point of view in this video is was makes it truly spectacular!


The next VTVL test flights will be made by the next follow up vehicle (being assembled and tested now) which is much closer to an actual flight configuration - taller and with leaner legs.

BTW, the flight before this (didn't see it linked here) made a very impressive lateral/sideways movement:

Now a New Shepard vehicle made a Mach 1.2 flight before it broke up:

Now? That was two years ago, and a lot smaller than this vehicle. I'm excited about Blue Origin as well, but they still haven't flown their follow-up vehicle. (As far as I know)

Anyway, the follow-up of GH will fly soon - and it will be much closer to the final booster stage. 30% taller, folding light-weight legs, capable of reaching 100km altitude. It might make its first test hops around new year.

Re: SpaceX's Grasshopper

FYI - Recently some images surfaced of the next "Grasshopper" test bed, named "F9R-Dev1": (click for higher resolution)


Here is a comparison picture to illustrate how much larger the new vehicle is than Grasshopper:


And the next Falcon 9 launch - this weekend - will be the first one flying with legs attached. The idea is to test a water soft landing, to build experience towards land landings:

Now that is a sexy rocket!

It's too bad it's a night launch. Will be pretty difficult for them to get good images of the water landing.

Re: SpaceX's Grasshopper

I am sure they can afford enough lighting to showcast their successful water "landing".

Or bringing a helicopter to attach a pipe for pumping fuel to have it hover until morning.

Or a tractor beam.

Re: SpaceX's Grasshopper

Flight of CRS-3 delayed to March 30. Preliminary reports are due to cleanup of contamination to cargo.

Re: SpaceX's Grasshopper

OK, so after a million delays, the flight has been completed, successfully again, and we have a fine water landing, computer reported everything fine, from leg deployment to "touchdown". No photos yet though. Apparently it hovered over water for only 8 seconds. The camera crew was running, but even they can't run that fast.

Re: SpaceX's Grasshopper

It didn't hover over the water for 8 seconds. It stopped transmitting 8 seconds after touching down in the water.

Re: SpaceX's Grasshopper

So it actually didn't work out as planned, I take it? Engines failed, because they were starved of fuel due to the centripetal forces on smashdown? (Note to SpaceX: Learn to blame the weather and high water next time!) Did it only prevent a longer hovering, or the safe soft landing was not as soft and as safe as they claim?

I guess that doesn't matter, what's important at this stage is the demonstration that they can do a controlled descent to be allowed to do those over land. I don't know if their last attempt counts, but once or twice more, and they will land over land. And any problems with the actual touchdown will be resolved long before then, and we'll begin seeing a record of actual landings (failed landings, at worst) to judge from.
