NASA and SpaceX launched four crew members toward the International Space Station. Liftoff was Thursday at 11:10 a.m.

Eastern time. It launched from Cape Canaveral Space Force Station in Florida.

Two NASA astronauts are on board. Jessica Watkins is the commander and Luke Delaney is the pilot.

Canadian astronaut Joshua Kutryk is also aboard. Russian cosmonaut Sergey Teteryatnikov is the fourth member.

The flight was expected to take about eight hours. They flew in a Dragon capsule described as retiring.

It launched on a Falcon 9 rocket. They will live and work there for six months on a science expedition.

They are expected to replace four people aboard since February. A fuel leak in the capsule caused a three-week delay.
