Live coverage: Falcon 9 disintegrates after launch

A Soyuz rocket launched Thursday with a Progress cargo freighter carrying more than 5,300 pounds of fuel, water, and supplies for the International Space Station’s six-person crew.

SpaceX’s Falcon Heavy rocket rolled out of its hangar and up the ramp to pad 39A at NASA’s Kennedy Space Center in Florida, then was raised vertical at the seaside launch complex early Monday in preparation for a late-night liftoff with two dozen weather observation and technology demonstration satellites.

NASA officials plan to host a news conference at 2 p.m. EST (1900 GMT) Monday to update the status of the Perseverance rover’s mission on Mars. During the briefing, NASA is expected to release first-of-its-kind video captured by the mission during its descent to the Red Planet.
