SpaceX’s first launch since August took off Saturday from Vandenberg Air Force Base in California. A Falcon 9 rocket deployed the first 10 next-generation Iridium communications satellites, part of a $3 billion upgrade to the company’s space network. Liftoff occurred at 9:54 a.m. PST (12:54 p.m. EST; 1754 GMT), and the Falcon 9’s first stage landed on a barge in the Pacific a few minutes later.

SpaceX’s Dragon supply ship reached the International Space Station on Wednesday, with astronaut Jeff Williams grappling the unpiloted spacecraft with the research lab’s robotic arm at 6:56 a.m. EDT (1056 GMT) after an automated rendezvous.

Follow the Atlas 5 rocket’s ascent into orbit from Cape Canaveral’s Complex 41 launch pad with the Orbital ATK Cygnus resupply ship for the International Space Station. Launch is scheduled for Tuesday at 11:05 p.m. EDT (0305 GMT).
