CAPE CANAVERAL, Fla. (AP) -- SpaceX has launched four astronauts to the International Space Station for NASA, less than two days after completing a flight chartered by millionaires.

The Falcon rocket blasted off before dawn Wednesday from Florida's Kennedy Space Center.

The crew includes the first Black woman making a long-term spaceflight, NASA's Jessica Watkins.

Also on board: the European Space Agency's lone female astronaut, Samantha Cristoforetti of Italy.

It's the first time NASA has sent up a crew comprised equally of men and women.

They should reach the space station Wednesday night.
