MS Musgrave handled hardware in the FWD MDDK

51F-13-021 (29 July-6 Aug 1985) --- Astronaut Story Musgrave, STS51F mission specialist, is seen hitching a zero-g ride on a blood centrifuge on the middeck of the space shuttle Challenger. "The centrifuge got more workout than just separation of our blood," crewmate John Bartoe, payload specialist, later told a gathering of media representatives at the 51F post-flight press conference, referring to Musgrave's off-duty antics.
