48th SHUTTLE MISSION TO BE LONGEST, FOCUS ON WEIGHTLESSNESS
Release: 92-81
The longest flight ever for a Space Shuttle and around-
the-clock investigations of the effects of weightlessness on
plants, humans and materials will highlight Shuttle mission
STS-50.
The 48th flight of a Space Shuttle and the 12th flight of
Columbia, STS-50, carrying the U.S. Microgravity Laboratory-1
(USML-1), is planned for launching at 12:05 p.m. EDT on late
June. The mission is scheduled to last 12 days, 20 hours and
28 minutes, with landing planned at Edwards Air Force Base,
Calif.
Richard N. Richards, 45, Capt., USN, will command STS-50,
his third space flight. The pilot will be Kenneth D. Bowersox,
36, Lt. Cmdr., USN, making his first space flight. Mission
specialists include Bonnie Dunbar, 43, who also will be Payload
Commander and making her third flight; Ellen Baker, 39, making
her second flight; and Carl Meade, 41, Col., USAF, making his
second flight. Payload specialists include Lawrence J.
DeLucas, 41, from the Center for Macromolecular Crystallography
at the University of Alabama, making his first flight, and
Eugene H. Trinh, 41, a research physicist on the Space Station
Freedom experiments planning group, making his first flight.
USML-1 includes 31 experiments ranging from manufacturing
crystals for possible semiconductor use to the behavior of
weightless fluids. In addition, STS-50 will carry the
Investigations into Polymer Membrane Processing experiment, an
experiment in manufacturing polymers, used as filters in many
terrestrial industries, and the Space Shuttle Amateur Radio
Experiment-II, an experiment that allows crew members to
contact ham radio operators worldwide and conduct question-and-
answer sessions with various schools.
Columbia is currently the only Shuttle capable of a 13-day
flight and will carry the necessary additional hydrogen and
oxygen supplies on a pallet in the cargo bay. New systems for
removing carbon dioxide from the crew cabin, for containing
waste and for increased stowage of food and crew equipment also
have been added.
The crew will perform several ongoing medical
investigations during the flight as well, research that aims at
counteracting the effects of prolonged exposure to
weightlessness on the human physique.
