Spacecraft are under construction, launch infrastructure is being modified and systems testing of all sorts is underway as NASA’s Commercial Crew Program works closely with Boeing and SpaceX to advance the new generation of American spacecraft designed to carry astronauts to the International Space Station from the United States. Boeing and SpaceX are building flight-like CST-100 Starliners and Crew Dragons, respectively, for evaluations prior to their flight test campaigns. Watch the testing, qualification and hardware buildup completed so far in 2016 in the video below toward the program’s goal of developing safe, reliable, cost-effective crew transportation systems.
