Liftoff of the Starlink 17-38 mission from Vandenberg Space Force Base in California happened at 9:35 a.m. PDT (12:35 p.m. EDT / 1635 UTC).

A new space weather observatory to be stationed a million miles from Earth has been enclosed inside the nose cone of a SpaceX Falcon 9 rocket for liftoff Sunday from Cape Canaveral.

A robotic U.S. Air Force space plane is set to land in California as soon as this week after a secretive 22-month flight hundreds of miles above Earth.
