Operation AXIOM: The Space Age—The 40th Anniversary of S.T.S.-61-A, Part II
31 October-6 November 1985: Spacelab D1—The crew split to conduct science twenty-four hours/day (Blue Team: Hartsfield, Nagel, Dunbar, Furrer, & Ockels; Red Team: Buckli, Bluford, & Messerschmid); the mission was paid for by & Spacelab's experiments operated from West Germany (D1 = Deutschland-1 ["Germany-1"]); after 112 orbits, the Challenger landed at California's Edwards.

Commentary: Flight operations were controlled from the Johnson Space Center in Houston, Texas, United States, payload operations from the German Space Operations Center in Oberpfaffenhofen, Bavaria, West Germany. This international, multi-site coordination helped pave the way for the International Space Station & the Artemis Program.

Commentary: I would have thought that with an eight-person crew, the Blue & Red Teams would each have four members. I have no idea why the Blue Team had five members & the Red Team only three.
