Bigelow Aerospace, makers of the inflatable space station system we've mentioned before, has finally announced the official terms of its own "space prize":
Anyone who wants to follow in the shoes of Burt Rutan and win the next big space prize will have to build a spacecraft capable of taking a crew of no fewer than five people to an altitude of 400 kilometers and complete two orbits of the Earth at that altitude. Then they have to repeat that accomplishment within 60 days.
From everything I've read, getting into orbit is much harder than the sub-orbital stuff Rutan's bunch has done (which was no walk in the park). However, it's definitely not impossible. Hey, I got a great set of metric wrenches in my garage. That's a start, right?
