Live coverage: SpaceX Falcon Heavy launches NASA’s Psyche on mission to a metal asteroid

SpaceX’s Falcon 9 rocket took off from Cape Canaveral on Friday afternoon, sending a Dragon cargo freighter on the way to the International Space Station as the launcher’s first stage booster returned to Earth aboard a floating platform.

A commercial Cygnus resupply ship named for Robert H. Lawrence, Jr. — the first African American selected as an astronaut — is awaiting liftoff Sunday evening from NASA’s Wallops Flight Facility on Virginia’s Eastern Shore to begin a 35-hour trip to the International Space Station.

The rollout operation on Tuesday followed a day of evaluations using Boeing’s weight and center-of-gravity machine to determine the final measurements on the spacecraft. Launch is still targeting May 6 at 10:34 p.m. EDT (0234 UTC).
