WASHINGTON — A Falcon 9 launched a Dragon cargo spacecraft May 15 carrying nearly 3,000 kilograms of cargo to the International Space Station.

The Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 6:05 p.m. Eastern. The launch was scheduled for May 12 but postponed a day because of a forecast of poor weather, while a May 13 attempt was scrubbed in the final minute of the countdown because of violations of launch weather criteria.

The Dragon spacecraft separated from the upper stage of the Falcon 9 nearly 10 minutes after liftoff. The spacecraft is scheduled to dock with the station’s Harmony module at about 7 a.m. Eastern May 17.

This is the sixth flight of this cargo Dragon capsule, designated C209, which made its first flight to the ISS in 2021. It is the first cargo Dragon spacecraft to reach this milestone, although the Crew Dragon spacecraft Endeavour has also flown six missions.
