Live coverage: Two Russians, one American arrive at space station

A SpaceX Falcon 9 rocket lifted off from Vandenberg Space Force Base in California at 11:02 p.m. PDT Tuesday (2:02 a.m. EDT; 0602 UTC Wednesday) with another batch of 52 Starlink internet satellites.

An automated SpaceX supply ship parachuted into the Pacific Ocean on Saturday, bringing more than 3,800 pounds of cargo — including a NASA robot requiring repair — back to Earth after a month-long mission at the International Space Station.

Boosted off planet Earth by a Russian Proton rocket, a European-built space probe departed for Mars on Monday, beginning a mission to test future landing technologies and search for methane, a potential signature of microbial life.
