       NASA Astronaut
 
BIRTHPLACE AND DATE:  Born February 5, 1947, in Southampton, New York.  Her
parents, Dr. and Mrs. Howard E. Cleave, reside in Williamstown, Massachusetts.
 
PHYSICAL DESCRIPTION:  Brown hair; green eyes; height: 5 feet 2 inches; weight:
103 pounds.
 
EDUCATION:  Graduated from Great Neck North High School, Great Neck, New York,
in 1965; received a bachelor of science degree in Biological Sciences from
Colorado State University in 1969, and a master of science in Microbial Ecology
and a doctorate in Civil and Environmental Engineering from Utah State
University in 1975 and 1979, respectively.
 
MARITAL STATUS:  Unmarried.
 
RECREATIONAL INTERESTS:  She enjoys cross-country and downhill skiing, sailing,
hiking, and camping.
 
ORGANIZATIONS:  Member of the Texas Society of Professional Engineers, the
Water Pollution Control Federation, Tri-Beta, Sigma Xi, and Tau Beta Pi;
associate member of the American Society of Civil Engineers.
 
SPECIAL HONORS:  Recipient of NASA Space Flight Medal (1985), NASA Exceptional
Service Medal (1988).
 
EXPERIENCE:  Dr. Cleave held graduate research, research phycologist, and
research engineer assignments in the Ecology Center and the Utah Water Research
Laboratory at Utah State University from September 1971 to June 1980.  Her work
included research on the productivity of the algal component of cold desert
soil crusts in the Great Basin Desert south of Snowville, Utah; algal removal
with intermittent sand filtration and prediction of minimum river flow
necessary to maintain certain game fish; the effects of increased salinity and
oil shale leachates on freshwater phytoplankton productivity; development of
the Surface Impoundment Assessment document and computer program (FORTRAN) for
current and future processing of data from surface impoundments in Utah; and
design and implementation of an algal bioassay center and a workshop for
bioassay techniques for the Intermountain West. In conjunction with her
research efforts, she has published numerous scientific papers.
 
NASA EXPERIENCE:  Dr. Cleave was selected as an astronaut in May 1980.  Her
technical assignments have included work at the Shuttle Avionics Integration
Laboratory (SAIL), CAPCOM on five Space Shuttle flights, Malfunctions
Procedures Book, and Crew Equipment Design.
 
Dr. Cleave was a mission specialist on STS-61B which launched at night from
Kennedy Space Center, Florida, on November 26, 1985.  During this mission the
crew members deployed the MORELOS-B, AUSSAT II, and SATCOM K-2 communications
satellites, conducted 2 six hour spacewalks to demonstrate Space Station
construction techniques with the EASE/ACCESS experiments, operated the
Continuous Flow Electrophoresis (CFES) experiment for McDonnell Douglas and a
Getaway Special (GAS) container for Telesat, Canada, conducted several Mexican
Payload Specialist Experiments for the Mexican Government, and tested the
Orbiter Experiments Digital Autopilot (OEX DAP).  This was the heaviest payload
weight carried to orbit by the Space Shuttle to date.  After completing 108
orbits of the Earth in 165 hours, STS-61B Atlantis landed on Runway 22 at
Edwards Air Force Base, California, on December 3, 1985.
 
On her second flight, Dr. Cleave was a mission specialist on the crew of STS-30
which launched from Kennedy Space Center, Florida, on May 4, 1989, aboard the
Orbiter Atlantis.  During this four day mission, crew members successfully
deployed the Magellan Venus-exploration spacecraft, the first U.S. planetary
science mission launched since 1978, and the first planetary probe to be
deployed from the Shuttle.  Magellan is arrived at Venus in mid-1990, and will
map the entire surface of Venus.  In addition, crew members also worked on
secondary payloads involving Indium crystal growth, electrical storm, and earth
observation studies.  Following 64 orbits of the earth, the STS-30 mission
concluded with a landing at Edwards Air Force Base, California on May 8, 1989.
 
With the completion of this flight she has logged a total of 262 hours in
space.
 
CURRENT ASSIGNMENT:  Dr. Cleave is detailed to Engineering at the Johnson Space
Center, where she serves as Special Assistant for Advanced Programs in the Crew
Systems and Thermal Division.
