Yeah, that's kind of my point. I'm guessing they could test
atmospheric rocket burn by creating a chamber with the right
atmosphere mix, but gravity.... sucks. If they over-calculate, they
stay too high before the fuel burns out, too low, and we've burnt
millions (billions?) on making a new crater in the surface of mars.
And that's just the rocket portion of the sky-crane idea, let alone
the deployment issues.
