SpaceX successfully deployed 60 more Starlink internet satellites in orbit Saturday, continuing a record launch cadence while engineers assess a concern with Falcon 9 rocket engines that has delayed other missions, including the next crew flight to the International Space Station.

A twin-engine Northrop Grumman Antares rocket climbed into orbit Saturday from Virginia’s Eastern Shore carrying a Cygnus supply ship bound for the International Space Station with a compact electron microscope, a flame combustion experiment, a range of biological investigations, fresh cheese, fruit and vegetables for the research lab’s three-person crew.

After being put back in position around the Delta 4-Heavy rocket after Thursday’s weather scrub, the 330-foot tall mobile service tower is retracted again at Cape Canaveral’s pad 37B for launch that will place the NROL-37 payload into Earth orbit.
