Richard B. Hoover

Hoover was born in Sikeston, Missouri on January 3, 1943. He obtained his B.Sc. degree with majors in physics, mathematics and French in 1964 from Henderson State University in Arkadelphia, Arkansas. He did graduate work in theoretical mathematics at Duke University on an NSF fellowship translating the Nicolas Bourbaki French volume on multi-dimensional vector spaces, and was completing his thesis on X-ray diffraction in the Physics Department of the University of Arkansas when he left the University in 1966 to join NASA.

Working at the NASA Marshall Space Flight Center in Huntsville, Alabama, beginning in 1966, Hoover has taken part in astrobiological research carried out there since 1997. In 1998, he participated in two of the astrobiology proposals funded by the newly formed NASA Virtual Astrobiology Institute. He was co-investigator with David McKay (PI) of the NASA Johnson Space Center on the study of biomarkers and microfossils in meteorites, astromaterials and ancient terrestrial rocks, and collaborated with Kenneth Nealson (PI) from NASA Jet Propulsion Laboratory on the investigation of microbial extremophiles from some of the Earth's most hostile environments as related to the co-evolution of planets and biospheres.

Hoover is noted for his early work at NASA on Fraunhofer diffraction, and the development of X-ray/EUV telescopes for solar physics research. He developed the "ATM Experiment S-056 grazing incidence X-ray telescope" and obtained 25,000 solar x-ray images from Skylab, and developed the instrument that obtained the first high resolution X-ray/EUV (X-ray to extreme ultraviolet) images of the Sun ever obtained with a normal incidence multilayer X-ray telescope.

He performed research on unicellular algae known as diatoms, and is noted for his discovery of microbial extremophiles from places such as Mono Lake, deep Lake Vostok ice cores, deep sea hydrothermal vents, and the living pleistocene bacterium Carnobacterium pleistocenium isolated from the 32,000-year-old permafrost from Fox Tunnel in Alaska. He organized and co-chaired the NASA/NATO/INTAS sponsored 'Astrobiology Advanced Study Institute' that was held in Chania, Crete in 2002. Hoover retired from NASA in December 2011.
