David S. McKay

As a graduate student in geology at Rice University, McKay was present at John F. Kennedy's speech in 1962^[4] announcing the goal of landing a man on the Moon within the decade. Inspired by Kennedy's speech, McKay as a NASA scientist trained the Apollo astronauts in geology. He was a chief trainer for Neil Armstrong and Buzz Aldrin during their last geology field trip in West Texas. On July 20, 1969, in Houston, McKay was the only geologist present in the Apollo Mission Control Room when Armstrong and Aldrin walked on the Moon, serving as a resource. He was named principal investigator to study the samples which they brought back from the Moon.^[5]

McKay studied lunar dust since the return of the first Apollo 11 samples in 1969, and contributed over 200 publications on this topic. As a result of this effort, McKay contributed to major discoveries, including:^[6]

• 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.

McKay published numerous papers and abstracts relating to planetary materials and space resource utilization: lunar regolith,^[7] cosmic dust, meteorites, Martian soil analogs, and technologies for producing oxygen, water, and building materials from lunar soil.^{[citation needed]}

The engineering simulant JSC-1 was developed by McKay, James Carter of The University of Texas at Dallas, and others.

McKay's team published their findings in 1996 regarding possible microfossil structures in Martian meteorite ALH 84001. McKay presented more than 100 talks at scientific and public gatherings on the possibility of life on Mars and the implications of that possibility.

McKay's research group conducted studies of nanobacteria, tiny life forms such as might be found in extraterrestrial environments. McKay's group was also part of a pioneering study on the effects of lunar dust on health. Using one of the largest returned Apollo regolith samples released to scientists, the research team separated and studied the tiniest sized lunar dust particles.^[8]

McKay was honored by the International Astronomical Union (IAU) by having asteroid 6111 Davemckay named for him in 2002.^[9] 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."

McKay's future wife, Mary Fae, was also in the audience at Rice Stadium during President Kennedy's pivotal speech, although McKay had not met her at that time. She went on to become a NASA technical editor.

McKay died in Houston, Texas, of heart disease.^[10]
