STS-35 ASTRO-1 MS Parker and Payload Specialist Durrance train at MSFC

STS-35 Mission Specialist (MS) Robert A.R. Parker (left) and Payload Specialist Samuel T. Durrance practice Astronomy Laboratory 1 (ASTRO-1) experiment procedures in a space shuttle aft flight deck mockup in the Payload Crew Training Complex at the Marshall Space Flight Center (MSFC) in Huntsville, Alabama. For all Spacelab missions, shuttle crew members train regularly in the facility in preparation to operate experiments on their Spacelab missions. The ASTRO-1 crew will operate the ultraviolet telescopes and instrument pointing system (IPS) from Columbia's, Orbiter Vehicle (OV) 102's, aft flight deck. The seven-member ASTRO-1 crew will work around the clock, in 12-hour shifts, to allow the maximum number of observations to be made during their nine or ten days in orbit. In addition to the commander and pilot, the crew consistss of three MSs and two payload specialists. (MSs are career astronauts who are trained in a specialized field. Payload specialists are members of the science investigator teams who were nominated by their peers to operate their experiments on orbit. They are trained and certified for flight by NASA.)
