When you're operating on a Cost Plus basis, the expense of all those layers of subcontractors and intensive testing is just a cost for the customer to cover.

So after the Antares launch, SpaceX launches their Grasshopper rocket to new heights.

Seems like the legs are smoldering pretty good there. I'll assume they've designed it so they don't eventually outright melt?

Mmmm... BBQed grasshopper leg.

Looks like the fuel pump turbine's exhaust velocity is low enough to be seriously shifted by the prevailing wind. Possible problem in hover, not a problem for ascent to orbit.

Here is a video of the old DCXA doing what the Grasshopper does.

Yeah, only that the Grasshopper is several times the size and will lead to an actual LV...
I loved the DC-X, dont get me wrong, was heartbroken when they cancelled it.

Let us hope that the Grasshopper doesn't do what the DCXA did there at the end.

Honestly, if you're going to do a long-term R&D program leading to an operational vehicle in the end, you've got to account for losing a couple of prototypes to unexpected issues/accidents at the outset. If SpaceX isn't prepared to continue the program even if a Grasshopper topples over and explodes, then they'll probably fail as much as NASA did with the DCXA.

SpaceX has already shown their willingness to persevere in the face of adversity. The first three flights of the Falcon 1 were failures. The 4th and 5th flights were successes and paved the way for the Falcon 9.

Look under Launch History.

Yeah, Elon Musk even said on several occasions that they expect to leave a few smoking craters in the Texas soil. So far they have done a really great job at avoiding that. Grasshopper 1 will soon retire though (to be replaced with GH2, which will be closer to the final first stage). I would not be surprised if they did a last, final flight that will take it beyond its limits. You can learn something from going beyond the limits of your test craft.
