SpaceX launched four astronauts to the International Space Station on Thursday in an eight-hour flight that set a US speed record, with commander Jessica Watkins becoming the first Black woman to lead a crewed mission to orbit.

The Dragon capsule lifted off from Cape Canaveral at 11:10 a.m. after a three-week delay to repair a leaking fuel system. Launch weather threatened throughout the morning but conditions cleared enough to proceed.

Watkins commanded the crew during the express trajectory to the ISS. The eight-hour flight duration represents the fastest crewed US spaceflight on record, according to SpaceX and NASA.

The mission marks a milestone for crew diversity in American spaceflight. Watkins' role as mission commander places her in a leadership position historically held by male astronauts. NASA selected her for the position based on her qualifications and experience.

The crew docked with the station on Thursday. No issues were reported during the ascent or docking procedure.
