The FAA, NASA, and the U.S. Military say "space" begins at 50 miles. That's why they qualified for the civilian astronaut pins. Some say it begins at the Karman Line, which is 62 miles. Either way it's a major accomplishment for a privately owned and operated endeavor.So this morning, Richard Branson successfully completed his virgin (heh) flight to space in his VSS Unity space plane. Pretty fascinating.
