NASA’s Northrop Grumman Cygnus Completes Solar Arrays Deployment

Northrop Grumman’s Cygnus spacecraft completed the deployment of its two solar arrays at 2:21 p.m. EDT after launching at 11:02 a.m. Aug. 4 on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida to the International Space Station for NASA.

Shortly after launch, the spacecraft missed its first burn slated for 11:44 a.m. due to a late entry to burn sequencing. Known as the targeted altitude burn, or TB1, it was rescheduled for 12:34 p.m., but aborted the maneuver shortly after the engine ignited due to a slightly low initial pressure state. There is no indication the engine itself has any problem at this time.
