Progress 64P: Full launch broadcast

NASA’s Ionospheric Connection Explorer satellite was scheduled to launch Wednesday aboard an air-dropped Northrop Grumman Pegasus XL rocket over the Atlantic Ocean, but managers aborted the mission after encountering a technical concern with the rocket following departure from Cape Canaveral Air Force Station. The launcher’s L-1011 carrier jet returned to Florida.

A SpaceX Falcon 9 rocket took off from NASA’s Kennedy Space Center in Florida at 8:25 a.m. EDT (1225 GMT) with 60 more Starlink internet satellites. SpaceX successfully recovered the first stage booster on a drone ship in the Atlantic Ocean.

The ever-dependable Delta 2 rocket continued its flawless service to NASA and Earth sciences Saturday with the launch of a $916 million environmental probe focused on producing global maps of soil moisture from space.
