Live coverage: SpaceX crew capsule moves to new space station docking port

NASA has shut down a spacecraft that measured the amount of solar energy entering Earth’s atmosphere for 17 years, more than three times the mission’s original design life.

After a 24-hour delay due to poor weather, an air-launched Northrop Grumman Pegasus XL rocket fired into orbit at 9:59 p.m. EDT Thursday (0159 GMT Friday) after release from a carrier jet at an altitude of 39,000 feet over the Atlantic Ocean northeast of Cape Canaveral. The Pegasus rocket carried NASA’s ICON satellite into orbit to collect measurements of the ionosphere.

SpaceX’s Falcon 9 rocket with 21 Starlink satellites on board will launch from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Station. Liftoff is no earlier than 7:44 p.m. PST (10:44 p.m. EST, 0344 UTC).
