This is one of things the US space program should do, in addition to space telescopes and observatories. The Space Station and other manned space travel is bunk, IMO. Too many silly Star Trek dreams. Of course, Obama will rant about this being something free enterprise didn't do, that we can thank big government for it, when no one mentions that Curiosity wouldn't have happened without Boeing and Lockheed-Martin. They are the real heroes. Yes, they did build that.
