Watch live as Elon Musk unveils his vision for missions to Mars

SpaceX has postponed its next launch of Starlink internet satellites from Wednesday after a Falcon 9 booster missed a landing attempt on an offshore drone ship during an otherwise successful mission Monday night.

SpaceX will perform a multi-hour experiment on the second stage of a Falcon 9 rocket after the launcher deploys a Dragon supply ship on the way to the International Space Station Thursday, gathering thermal data and other information to verify the vehicle’s ability to perform long-duration missions and inject payloads into demanding, high-energy orbits.

Ground teams are evaluating a payload failure on a Maxar-built SiriusXM radio broadcasting satellite that launched from Cape Canaveral in December on a SpaceX Falcon 9 rocket, officials said Wednesday.
