  Antares/NG-18: Good morning; Northrop Grumman's Cygnus cargo ship is closing in on the International Space Station; telemetry indicates one of its 2 solar arrays is only partially deployed; controllers are awaiting video from the ISS to confirm its actual state

  Antares/NG-18: The Cygnus is now visible from the ISS; while still too far out for any clear detail (600 meters), the spacecraft has a clearly asymmetrical appearance with only one solar array obviously extended

• Oh, so the array *is* deployed, it's just the panel hasn't folded out!

  Quite reminiscent of Lucy, by the way. Wonder if Cygnus also uses the landyard method to deploy the UltraFlex. If so and the problem is traceable to that, they may get a bounty of information (and could maybe experiment while berthed) to help the probe.

  The @NorthropGrumman #Cygnus space freighter is being powered by one of two solar arrays as it approaches the station today. The second solar array did not fully deploy after Cygnus' launch on Monday.

  Cygnus switches to its TriDAR proximity navigation system to continue through final approach.

• MCC advises the ISS crew that TriDAR 1 and 3 are operational but some problems in TriDAR 2 developed into having it completely fail. Were either of the other two TriDARs to fail, it would trigger an automatic abort.

  Antares/NG-18: NASA reports LIDAR 2 aboard Cygnus failed earlier; the LIDARs (light detection and ranging) use lasers to compute the range to ISS; if LIDAR 1 or 3 fails from this point on, an automatic abort will be executed, but both are operating normally
