Live coverage: SpaceX grounds launch to wait for better recovery weather

The Cargo Dragon spacecraft, tail number C209, will carry 6,659 lbs. (3,021 kg.) of science and supplies to the orbiting outpost. Liftoff from pad 39A at NASA’s Kennedy Space Center happened Monday, April 21, at 4:15 a.m. EDT (0815 UTC).

Launching from Vandenberg Air Force Base on California’s Central Coast on its third try, United Launch Alliance’s Delta 2 rocket lifted off Saturday with NOAA’s JPSS 1 polar-orbiting weather satellite.

SpaceX called off a scheduled launch of a Falcon 9 rocket about a half-hour before liftoff from Cape Canaveral Monday due to strong upper level winds, and officials aim to try again to send 60 Starlink Internet satellites into orbit Wednesday after bypassing a planned launch attempt Tuesday due to poor weather in the offshore booster recovery area.
