Photos: Liftoff of Atlas 5 from California

Three days after high winds scrubbed a launch attempt Friday, Rocket Lab launched an Electron rocket with four satellites from New Zealand at 1212 GMT (8:12 a.m. EDT) Monday.

SpaceX’s Falcon 9 rocket ignited its main engines at Cape Canaveral’s Complex 40 launch pad Thursday night, clearing a major hurdle before liftoff May 31 with the SES 12 communications satellite.

Eight of Iridium’s first ten upgraded communications satellites launched in January started providing voice and data relay service ahead of schedule, and SpaceX says it can launch up to 40 more Iridium spacecraft by the end of the year, Iridium officials reported Thursday.
