Space station commander Chris Cassidy and Robert Behnken plan to float outside Friday for the first of up to four spacewalks needed to complete the replacement of aging batteries in the lab’s solar power system. NASA managers hope to get the work done in time for Behnken and crewmate Douglas Hurley to return to Earth aboard their Crew Dragon capsule by around Aug. 2, officials said Wednesday.

The Falcon 9 rocket that will launch a Dragon capsule packed with cargo destined for the International Space Station was raised into position at launch complex 39A at the Kennedy Space Center.

The Starlink 8-2 mission from the company’s West Coast launch pad features 13 more satellites boasting a Direct to Cell capability. Liftoff from Vandenberg Space Force Base happened at 9:30 p.m. PDT (12:30 a.m. EDT, 0430 UTC) on Thursday.
