STS-61-A (also known as D-1) was the 22nd mission of NASA's Space Shuttle program. It was a scientific Spacelab mission, funded and directed by West Germany – hence the non-NASA designation of D-1 (for Deutschland-1). STS-61-A was the last successful mission of the Space Shuttle Challenger, which was destroyed during STS-51-L in 1986. STS-61-A currently holds the record for the largest crew, eight people, aboard any single spacecraft for the entire period from launch to landing.
The mission carried the NASA/ESA Spacelab module into orbit with 76 scientific experiments on board, and was declared a success. Payload operations were controlled from the German Space Operations Center in Oberpfaffenhofen, West Germany, instead of from the regular NASA control centers.
Single piece construction with modern embroidery. Radial white border stitching with a crude "ESA" symbol.
