"SpaceX's first crewed mission... doesn't mark the return of human spaceflight to American soil. The suborbital space tourism company Virgin Galactic notched that milestone..."
Jeeze, Wall, are you on Branson's PR staff or something? Yes, the VSS Unity is technologically innovative, and I hope the space tourist business does well. And yes it's fun to watch, and I would have given my right arm to be one of the pilots. I bet it was a helluva ride, but it qualified as "manned
space flight" only if you use NASA's current dumbed-down 50-miles-high definition of space. Even so, it barely cleared that low bar; Alan Shepard went TWICE as high almost SIXTY YEARS ago.
To compare the Virgin Galactic hop with SpaceX's upcoming manned orbital mission, and somehow claim that VG "beat" SpaceX to manned U.S. space flight, is just
pathetic. It reminds me of when in 1965 the Soviets, watching the astronauts of America's Gemini 6A and Gemini 7 maneuver into orbital formation flight only six feet apart, whined to anyone who would listen that the USSR had achieved the first "rendezvous" three years earlier... though Vostok 3 and 4 had never come closer than about four miles.
To make a comparison, things have got to be at least comparable, and the Virgin Galactic "joy ride" just isn't in the same class as a working, usable man-rated space craft. You might as well compare Musk's SpaceX to Disney's Space Mountain.
