#ICYMI: @NorthropGrumman's Cygnus space freighter, loaded with science gear and spacewalk hardware, was captured using the Canadarm2 robotic arm and installed to the station's Unity module on Wednesday, Nov. 9, 2022.

Update: Per Northrop Grumman, this is debris from an "acoustic blanket". Possible that it came from inside the fairing, where it would have been used to shield Cygnus from noise & vibrations during launch. Probably got snagged on the array when the fairing separated.

Here's a look inside the Antares fairing that protects Cygnus during launch, complete with mylar blankets. This could be the material that became jammed in the array. Image credit: @ken_kremer

Image of Cygnus NG-18 arriving at ISS with one array undeployed. The 2nd image is a zoomed-in view of the undeployed array compared with the same angle of a deployed array - it appears to me as though some foam-like material has "bulged" out of the folded array (see red circle)?

Acoustic blanket material from inside the fairing, probably due to Cygnus snagging the fairing during separation because the whole vehicle was in motion, possibly rotating, at the time of separation, for reasons still unexplained.  Thruster firings around this time might also be an explanation.
