" Original video clip from Nasa Flight STS-37. Shows odd moving object close to the shuttle. The source of the video was from an external camera on space Shuttle Atlantis - April, 1991. "

It lookes like trash

its probably just a fly on the window, or some kinda satellite changing coruse via ground control instruction
