SpaceX launched four astronauts to the International Space Station for NASA on Wednesday, less than two days after completing a flight chartered by millionaires.
It's the first NASA crew comprised equally of men and women, including the first Black woman making a long-term spaceflight, Jessica Watkins.
“This is one of the most diversified, I think, crews that we've had in a really, really long time," said NASA's space operations mission chief Kathy Lueders.
