Live coverage: SpaceX Falcon Heavy launches NASA’s Psyche on mission to a metal asteroid

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.

In a reshuffling of SpaceX’s launch schedule, a Falcon 9 rocket is set for liftoff no earlier than Dec. 8 on a mission to deliver several tons of supplies and experiments to the International Space Station and return to service a Cape Canaveral launch pad damaged in a catastrophic rocket explosion last year.

The mission was SpaceX’s third orbital launch of the year and 99th in total from Launch Complex 39. Liftoff of the Starlink 12-11 mission occurred at 10:27 a.m. EST (1527 UTC).
