David S. McKay
David S. McKay is Chief Scientist for Astrobiology at the Johnson Space Center. McKay was the first author of a scientific paper postulating past life on Mars on the basis of evidence in Martian meteorite ALH84001 found in Antarctica.[1] This paper has become one of the most heavily cited papers in planetary science. The NASA Astrobiology Institute was founded partially as a result of community interest in this paper and related topics.
Lunar dust
McKay has studied lunar dust since the return of the first Apollo 11 samples in 1969, and has contributed over 200 publications on this topic. As a result of this effort, McKay has contributed major discoveries, including:
- Source of vapor deposition on lunar soil grains
- Formation of nano-phase iron globules on lunar soil grains
- Processes on the Moon that contribute to grain size distribution
- Space weathering and chemically activated nature of in-situ lunar dust
Space resources and planetary materials
McKay has published numerous papers and abstracts relating to planetary materials and space resource utilization: lunar regolith, cosmic dust, meteorites, Martian soil analogs, and technologies for producing oxygen, water, and building materials from lunar soil.
Lunar simulants
The engineering simulant JSC-1 was developed by McKay, James Carter of The University of Texas at Dallas, and others.
Controversy
In 1996, McKay's team published their findings regarding possible microfossil structures in Martian meteorite ALH84001. McKay has presented more than 100 talks at scientific and public gatherings on the possibility of life on Mars and the implications of that possibility.
Contributions to medical science
Asteroid Davemckay, #6111
McKay was honored by the International Astronomical Union (IAU) by having an asteroid named after him in 2002. His IAU citation mentions his years of work on lunar samples as well as the positive effect his research on Martian meteorites has had on planetary research.
“It was an unexpected but very high honor to have an asteroid named after me,” McKay said. “If it ever crashes into Earth, I will probably get the blame, but in the meantime it is very nice to have it out there orbiting the Sun for perhaps the next few billion years.”
