Atmospheric Laboratory for Applications and Science

Project Description
Atlantis will carry the Atmospheric Laboratory for Applications and
Science-1 (ATLAS-1), 12 instruments from the United States, France,
Germany, Belgium, Switzerland, the Netherlands and Japan, that will
conduct 13 experiments to study the chemistry of the atmosphere, solar
radiation, space plasma physics and ultraviolet astronomy. ATLAS-1 is
planned to be the first of several ATLAS flights designed to cover an
entire 11-year solar cycle, the regular period of energetic activity
by the sun. Co- manifested with ATLAS-1 is the Shuttle Solar
Backscatter Ultraviolet Instrument (SSBUV), which provides highly
calibrated measurements of ozone to fine-tune measurements made by
other NASA and NOAA satellites.

Commanding Atlantis will be Charles Bolden, making his third
space flight. Brian Duffy will serve as pilot, making his first
shuttle flight. Mission Specialists include Kathy Sullivan, making
her third flight; Dave Leestma, making his third space flight; and
Mike Foale, making his first space flight. Payload specialists will
be Byron Lichtenberg, making his second flight, and Dirk Frimout,
Belgian Scientist, making his first flight.

ATLAS operations will continue 24 hours a day, with the crew
split into two teams each on a 12-hour shift. The Red Team will
consist of Leestma, Foale and Lichtenberg. The Blue Team will be
Duffy, Sullivan and Frimout. Bolden, as Commander, will set his own

Secondary experiments aboard Atlantis will include Space Tissue
Loss, a study of the effects of weightlessness on body tissues; the
Visual Function Tester, a study of the effects of weightlessness on
human vision; the Radiation Monitoring Equipment, an often-flown
device that measures radiation aboard the Shuttle; Investigations into
Polymer Membrane Processing, a study of developing polymer membranes
used as filters in many industries and in space and the Cloud Logic to
Optimize Use of Defense Systems, an investigation to quantify the
variation in apparent cloud cover as a function of the angle at which
clouds of various types are viewed.

Also flying on STS-45 will be NASA's Get Away Special payload, a
program which provides individuals and organizations the opportunity
to send scientific research and development experiments on board a
Space Shuttle.

In addition, the Shuttle Amateur Radio Experiment will provide
amateur radio operators worldwide, plus students at several selected
schools, the opportunity to converse with crew members aboard
