SES, the international communications satellite operator, plans to send two more C-band television broadcasting spacecraft into orbit from Cape Canaveral Friday night atop a SpaceX Falcon 9 rocket on a mission that will help clear spectrum for transition to 5G network services.

With the performance hit on the Atlas 5 rocket’s most recent flight last month now isolated to a faulty valve, preparations to resume the manifest are underway as United Launch Alliance workers stack the next booster for blastoff this summer.

The Atlas 5 rocket emerges Monday from the Vertical Integration Facility for rollout to Complex 41 at Cape Canaveral in preparation to launch the Orbital ATK Cygnus resupply ship to the International Space Station.
