Live coverage: Kennedy Space Center to reopen Friday

The Centaur upper stage launching the Cygnus space freighter Tuesday persevered through a velocity shortfall from the first stage of the Atlas 5 rocket, improvising with a longer firing to reach the correct orbit.

SpaceX lofted another batch of Starlink internet satellites into orbit on Friday from Vandenberg Space Force Base in California. A Falcon 9, with 48 satellites inside its payload fairing, lifted off at 12:29:50 p.m. PDT (3:29:50 p.m. EDT; 1929:50 UTC) from Space Launch Complex 4-East.

SpaceX’s third Falcon Heavy rocket is set for liftoff from NASA’s Kennedy Space Center in Florida, and the heavy-lift launcher will head on an easterly course over the Atlantic Ocean atop more than 5 million pounds of thrust.
