Watch SpaceX launch NASA astronauts into space in a historic mission

SpaceX launched NASA astronauts for the first time. The mission is called Demo-2, and it is the first launch of NASA astronauts from the U.S. since 2011. It is also the first crewed launch in the history of Elon Musk’s company, its most important milestone yet. SpaceX postponed the first launch attempted due to severe weather in the area.
