After scrubbing a launch attempt Friday, SpaceX launched a Falcon 9 rocket Saturday on a mission to send communications satellites from OneWeb and Iridium into polar orbit from Vandenberg Space Force Base, California. Liftoff occurred at 6:16 a.m. PDT (9:16 a.m. EDT; 1316 UTC).

Departing Cape Canaveral at 8:37 a.m. EDT Thursday, the United Launch Alliance Atlas 5 rocket lifted a classified national security satellite into orbit for deployment.

The towering structure to be used for liftoffs of NASA’s Space Launch System rolled from a construction site to launch pad 39B at the Kennedy Space Center in Florida this week, arriving at the seaside complex Friday for a week of fit checks.
