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

Ground crews loaded time-critical experiments, including 20 mice to help scientists study muscle atrophy, into SpaceX’s commercial Dragon cargo capsule Thursday, a day before a launch planned from Cape Canaveral toward the International Space Station.

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral early Tuesday, heading due east over the Atlantic Ocean to deliver the EchoStar 23 communications satellite into orbit 34 minutes later.

A SpaceX Falcon 9 rocket lifted off from Cape Canaveral at 7:10 p.m. EST Monday (0010 GMT Tuesday) with the JCSAT 18/Kacific 1 communications satellite, heading for a position in geostationary orbit to beam broadband signals across the Asia-Pacific. The launcher deployed the satellite into an on-target orbit, and the first stage returned to land on SpaceX’s drone ship in the Atlantic Ocean.
