NASA and SpaceX have delayed the launch of the Crew Dragon “Resilience” spacecraft from the Kennedy Space Center until 7:27 p.m. EST Sunday (0027 GMT Monday) to wait for improved downrange weather and sea conditions, and better onshore winds at the launch site.

The mission launched the first two of six Earth observation satellites built by Maxar Space Systems. Liftoff from Space Launch Complex 4 East happened at 11:36 a.m. PDT (2:36 p.m. EDT, 1836 UTC).

High winds predicted off the coast of Florida this week will keep SpaceX’s Crew Dragon Resilience spacecraft and its four-person crew in orbit until Saturday, three days after their previously scheduled return to Earth from the International Space Station.
