A Falcon 9 rocket carrying the Crew-10 successfully launched from NASA's Kennedy Space Center at 7:03 p.m. ET.

Butch Wilmore and Suni Williams need SpaceX to get a relief team to the space station before they can check out. Arrival is set for late Saturday night.

Wilmore and Williams flew to the station in June as the first test crew of Boeing's Starliner, which suffered propulsion system issues in space. NASA deemed it too risky for the astronauts to fly home on the Boeing craft. This led to the current plan to bring them home in a SpaceX capsule.
