Watch a time-lapse of the Falcon 9 rocket going vertical

SpaceX’s fifth launch of replacement spacecraft for Iridium’s global voice and data communications network is set for March 29 from Vandenberg Air Force Base in California, a flight that Iridium hopes will signal the start of a brisk pace of West Coast missions to complete deployment of the telecom company’s initial 75-satellite constellation this summer.

SpaceX launched two Falcon 9 rockets in a span of a little more than four hours Friday, a record-setting day that began with the launch of 52 Starlink internet satellites from California and ended with the sunset liftoff of two SES television broadcast payloads from Florida.
