The International Near-Earth Asteroid Survey (INAS) was organized and co-ordinated by Eleanor F. Helin during the 1980s, as the international aspect of the Planet-Crossing Asteroid Survey (PCAS). INAS attempted to expand the sky coverage (PCAS operated exclusively from Palomar Observatory) and the discovery and recovery of Near-Earth asteroid (NEAs) around the world.
Famous quotes containing the word survey:
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
