The solar panels of Cygnus are unable to deploy
Hours after its Nov. 7 launch, one of the two solar arrays on the Northrop Grumman Cygnus cargo spacecraft failed to deploy. NASA is currently debating whether or not the vessel can safely approach the International Space Station. The NASA Cygnus spacecraft, which was carrying out the NG-18 mission, was supposed to release its two circular UltraFlex solar arrays roughly three hours after liftoff from Virginia atop an Antares rocket.
