SpaceX scrubbed the planned launch of its next set of Starlink satellites Friday. A Falcon 9 rocket is awaiting liftoff from pad 39A at the Kennedy Space Center in Florida with 57 Starlink Internet satellites and two commercial Earth-imaging microsatellites for BlackSky.

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Cape Canaveral with NASA’s Tracking and Data Relay Satellite-M. Launch is scheduled for Friday at 8:03 a.m. EDT (1203 GMT).

Three new crew members embarked on a six-month expedition aboard the International Space Station Thursday with a launch from Kazakhstan on top of a Russian Soyuz rocket at 0805 GMT (4:05 a.m. EDT). NASA astronaut Chris Cassidy and crewmates Anatoly Ivanishin and Ivan Vagner docked with the space station at 1413 GMT (10:13 a.m. EDT) Thursday.
