International Near-Earth Asteroid Survey

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.
