NASA Interest

Exhaustive Interest : Physics of the Earth, including its atmosphere and its hydrosphere, as revealed by aircraft, satellite, and manned spacecraft observations; observation of natural phenomena; upper atmosphere and ionosphere; geomagnetism and Earth gravitational field; paleontology related to development of life; geological investigations having potential relevance to ground truth for remote sensing or Earth evolution and structure.

Selective Interest : Geology of direct interest to aerospace activities.

Negative Interest : Surface surveys; surface or seismic prospecting; assaying processes or records.
