On the post I made about the Dream Chaser spacecraft, Steve Morris called my attention to the Skylon Spaceplane. It takes off as a plane, but has an jet engine that can switch into rocket mode, allowing it to rocket into orbit. It reenters much as the shuttle did, but still has enough fuel to land as a plane.
Many companies appear to have given up on single state to orbit designs (SSTO), but not British company Reaction Engines Limited. If they succeed, they may drastically reduce the cost of getting into orbit, and that could be a major game changer.
Of course, the proof will be in the pudding. But I’m glad to see all this innovation going on in the space industry. It seems to bode well for the future of human spaceflight.
