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

Passing a major pre-flight milestone ahead of a launch and landing planned early Sunday, a SpaceX Falcon 9 rocket ignited its main engines Wednesday for a hold-down firing at Cape Canaveral.

Fresh from its inaugural test flight in space, Boeing’s first reusable Starliner crew capsule has been named “Calypso” by NASA astronaut Suni Williams, who will command the same vehicle on its next trip into orbit.

The astronaut “is in stable condition under observation as a precautionary measure,” NASA said in a statement 10 hours after the Crew Dragon’s landing. “To protect the crew member’s medical privacy, specific details on the individual’s condition or identity will not be shared.”
