Live coverage: Four astronauts return home after 167 days in space

A senior SpaceX official said this week that “heat damage” led to the failure of a Falcon 9 booster during a landing attempt Feb. 15, but the company will press on with more launches and will likely surpass the 10-flight threshold on one of its reusable rockets soon. The next Falcon 9 launch, using a booster flying on its eighth mission, is scheduled for liftoff from Florida with 60 more Starlink internet satellites Sunday night.

Russian cosmonaut Alexander Skvortsov, joined by Italian flight engineer Luca Parmitano and NASA astronaut Andrew Morgan, plans to relocate his Soyuz spacecraft to a new docking port on the International Space Station late Sunday (U.S. time), clearing a spot for the unpiloted Soyuz MS-14 spaceship to attempt another automated approach to the complex Monday after aborting its first rendezvous, Russian officials said.

SpaceX scrubbed the first test launch of its huge new rocket Monday due to a frozen valve in the pressurization system on the 33-engine Super Heavy booster, delaying the widely-anticipated flight from South Texas until at least Thursday.
