Photos: Falcon 9 breaks apart en route to ISS

A previously-flown Falcon 9 booster blasted off Friday from Vandenberg Air Force Base on California’s Central Coast with 10 new-generation communications satellites for Iridium. Launch occurred 8:27 p.m. EST (5:27 p.m. PST; 0127 GMT).

The mission is a follow-on from NASA’s planetary defense mission, DART, which succeeded in changing the orbit of an asteroid around its larger neighbor. Liftoff happened at 10:52 a.m. EDT (1452 UTC).

A SpaceX Falcon 9 rocket took off from Kennedy Space Center’s launch pad 39A on Thursday, then its first stage booster touched down on a nearby landing target after sending a U.S. Air Force X-37B spaceplane toward orbit.
