Watch the Falcon 9 launch from pad 39A

Seven astronauts and cosmonauts are gearing up for launches April 9 and April 22 to the International Space Station, replacing seven outgoing crew members set to land in Kazakhstan and off the coast of Florida on April 17 and April 28.

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.

The next chance for SpaceX to return a Falcon 9 booster to landing at Cape Canaveral will come in mid-July, when the company plans to launch a Dragon supply ship to the International Space Station, a company official said Tuesday.
