Mostly clear skies and brisk westerly winds are forecast at launch time Friday afternoon for SpaceX’s first resupply mission to the International Space Station in nearly a year.

The U.S. Space Force has decided to delay the planned late February launch of two military satellites aboard a ULA Atlas 5 rocket to “evaluate readiness” of one of the payloads, giving officials a window to move forward the liftoff of an unpiloted test flight of Boeing’s Starliner crew capsule to no earlier than March 25.

Astronauts Doug Hurley and Bob Behnken undocked from the International Space Station Saturday aboard a Crew Dragon capsule, heading for a parachute-assisted splashdown Sunday in the Gulf of Mexico to wrap up a 64-day test flight of SpaceX’s commercial human-rated spaceship.
