Live coverage: Proton rocket blasts off for first time in a year

A SpaceX Falcon 9 rocket lifted off from Vandenberg Space Force Base in California at 12:26 p.m. PDT (3:26 p.m. EDT; 1926 GMT) Friday with another batch of 52 Starlink internet satellites. The mission is the first of two SpaceX launches scheduled Friday, with another Falcon 9 poised for liftoff from Florida a little more than four hours later.

These photos chronicle the activities of Russian cosmonaut Fyodor Yurchikhin and NASA astronaut Jack Fischer on Thursday as they prepared for liftoff on a Soyuz rocket to begin an expedition of more than four months on the International Space Station.

After a six-week delay for undisclosed reasons, SpaceX raised a Falcon 9 vertical on its launch pad Thursday at the Kennedy Space Center in Florida for another try early Friday to send into orbit the company’s next batch of Starlink Internet relay stations and a pair of commercial BlackSky Earth-imaging microsatellites.
