Astronaut Story Musgrave in EMU in thermal vacuum chamber

S93-34001 (26 May 1993) --- Astronaut F. Story Musgrave, wearing a training version of the Extravehicular Mobility Unit (EMU), participates in a dry run for tests in a thermal vacuum chamber. The payload commander will be among four suited crew members participating in task rehearsals and testing the tools that will be used on the Hubble Space Telescope (HST) repair mission. The test, conducted in Chamber B of the Space Environment and Simulation Laboratory (SESL) at the Johnson Space Center (JSC), verified that the tools being designed for the mission will work in the cold vacuum of space. Others pictured, from the left, are Andrea Tullar and Donna Fender, test directors; Leonard S. Nicholson, acting director of engineering; and astronauts Thomas D. Akers and Kathryn C. Thornton, mission specialists, along with Musgrave.
