STS037-13-036 (5-11 April 1991) --- Astronaut Steven R. Nagel talks to ground controllers from the commander's station on the space shuttle Atlantis. He is wearing the special partial pressure suit used by space shuttle crew members for ascent and entry phases. Nagel, mission commander, and four other astronauts spent six days in space during which they readied the Gamma Ray Observatory (GRO) for deployment, released it into space, tested possible Space Station Freedom translation aid devices, conducted experiments, took photographs and performed other duties. This frame was taken with a 35mm camera. 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).
