Follow the key events of the Falcon 9 rocket’s ascent to orbit with the fifth set of 10 next-generation satellites for Iridium’s voice and data relay fleet.

A high-throughput communications satellite developed as a joint venture between Telesat and APT Satellite lifted off on top of a SpaceX Falcon 9 rocket at 12:45 a.m. EDT (0445 GMT) Monday from Cape Canaveral, following a delay to wait for storms to clear the Florida spaceport.

A Falcon 9 rocket and 60 more Starlink internet satellites set for launch early Sunday at Cape Canaveral will mark the first time SpaceX has flown a first stage 10 times, reaching a milestone that the company once said could be a limit for reusing boosters. Now SpaceX plans to keep flying reused rockets on Starlink missions until one fails.
