Mary Louise Cleave (born 5 February 1947) is an American engineer and a former NASA astronaut. She also served from 2004 to 2007 as NASA Associate Administrator for the Science Mission Directorate.
Cleave was born in Southampton, New York as the daughter of Howard Cleave and Barbara Cleave, both teachers. She grew up in Great Neck, New York, and has an older (Trudy Carter) and a younger sister (Barbara "Bobbie" Cleave Bosworth).
In 1965 Cleave graduated from Great Neck North High School, Great Neck, New York. In 1969 she received a bachelor of science degree in Biological Sciences from Colorado State University, and in 1975 a master of science in Microbial Ecology from Utah State University. In 1979 she received a doctorate in Civil and Environmental Engineering from Utah State University.
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.
