STS037-54-004 (5-11 April 1991) --- Four crew members have fun with weightlessness on the Space Shuttle Atlantis' middeck. Astronaut Kenneth D. Cameron, pilot, performs a "quick hands" feat with three tape cassettes -- obviously a feat much more difficult on Earth. Looking on, left to right, are astronauts Linda M. Godwin, mission specialist; Steven R. Nagel, mission commander; and Jerry L. Ross, mission specialist. Ross later used the microgravity environment to have some fun with the bag of malted milk balls in his hands. This 35mm frame was exposed by astronaut Jerome (Jay) Apt, mission specialist. This was one of the visuals used by the crew members during their April 19 Post Flight Press Conference (PFPC) at the Johnson Space Center (JSC).
