Disgrifiad
English: Eleanor F. “Glo” Helin (1932–2009) was active in planetary science and astronomy for more than 40 years at the California Institute of Technology and NASA’s Jet Propulsion Laboratory. In the early 1970s, she initiated the Palomar Planet-Crossing Asteroid Survey (PCAS) from Palomar Observatory, searching for large near-Earth asteroids (NEAs). This photographic program concluded after 25 years when the Near-Earth Asteroid Tracking (NEAT) project began in 1995. She remained with NEAT until her retirement in 2002, utilizing Air Force telescopes on Ha-leakala Observatory, Maui, Hawaii, and expanding NEAT to include an upgraded Palomar 48-inch (1.2-meter) Oschin Schmidt telescope.
