Watch the Falcon Heavy roar to life

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Sunday evening, heading due east over the Atlantic Ocean to deliver the Intelsat 35e communications satellite into orbit 32 minutes later.

The four astronauts preparing to ride SpaceX’s Crew Dragon “Resilience” into orbit climbed aboard their spaceship Thursday at the Kennedy Space Center in a practice run for a launch to the International Space Station planned Saturday night, while mission managers monitored weather and sea conditions in recovery areas across the Atlantic Ocean.

SpaceX rolled out a Falcon 9 rocket Sunday night to pad 39A at NASA’s Kennedy Space Center in Florida for liftoff with the next 60 Starlink internet satellites, but officials have pushed back the launch until Wednesday.
