An assignment patch of the CSA
The Canadian Space Agency was a Human space exploring organization founded in Canada in the late 20th century. This agency worked closely with NASA in training their astronauts for the space shuttle orbiter program. An assignment patch of this agency was displayed in the 602 Club in 2143.
