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

SpaceX has launched a Falcon 9 rocket with a previously-flown first stage booster carrying the SES 12 communications satellite, an all-electric, multi-band video and data relay platform to serve the Asia-Pacific region. Liftoff from Cape Canaveral occurred at 12:45 a.m. EDT (0445 GMT), and SpaceX did not plan to recover the first stage.

Northrop Grumman’s Pegasus XL rocket will take about 11 minutes to place NASA’s Ionospheric Connection Explorer, or ICON, satellite into a roughly 357-mile-high (575-kilometer) orbit after an airborne launch off Florida’s east coast.

SpaceX’s reused Falcon 9 first stage booster returned to a landing on an ocean-going platform a few minutes after launching March 30 with the SES 10 communications satellite, then returned to Port Canaveral early Tuesday.
