Live coverage: Falcon Heavy engines test-fired for launch next week

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into space from Cape Canaveral with NASA’s Mars 2020 mission.

SpaceX’s second Falcon Heavy rocket lifted off Thursday with the Arabsat 6A communications satellite. The world’s most powerful operational launcher lifted off from pad 39A at NASA’s Kennedy Space Center in Florida at 6:35 p.m. EDT (2235 GMT), and its three first stage boosters landed less than 10 minutes later — two back at Cape Canaveral and one on a drone ship at sea.

Another SpaceX Starship rocket stands fully integrated against the South Texas horizon and company-founder Elon Musk said from his perspective, they’re ready to launch. However, the Federal Aviation Administration has not yet issued a launch licence.
