NASA and SpaceX successfully launched four astronauts to the International Space Station on Friday. The Crew-11 mission took off at 11:43 a.m. from Launch Complex 39A at NASA’s Kennedy Space Center. Friday’s launch comes after weather forced SpaceX to scrub the launch on Thursday with 1 minute to go.

On August 1, SpaceX launched its 11th crew rotation for NASA. The four will spend six to eight months on the International Space Station.

The SpaceX Crew-11 mission is scheduled to launch from NASA’s Kennedy Space Center in Florida on Friday. The launch attempt is slated for 11:43 a.m. If needed, a backup opportunity is available on Saturday at 11:21 a.m. The Crew-11 launch was scrubbed at the last minute on Thursday after clouds rolled in, posing a weather risk.
