Construction crews at Cape Canaveral’s Complex 40 launch pad are busily repairing and upgrading the facility after a SpaceX Falcon 9 rocket exploded there last year, with the pad’s return to service scheduled before the end of the summer, clearing the way for final preparations for the triple-core Falcon Heavy’s maiden flight late this year.

SpaceX’s Falcon 9 rocket will launch a third-generation GPS navigation satellite for the U.S. military in 2018, the Air Force said Wednesday, breaking a monopoly held by United Launch Alliance since its formation nearly a decade ago.

SpaceX test-fired a Falcon Heavy rocket Wednesday night at the Kennedy Space Center in preparation for launch June 24 with a stack of weather observation and technology demonstration satellites.
