Steven Jeffrey Ostro (March 9, 1946 – December 15, 2008) was an American scientist specializing in radar astronomy. He worked at NASA's Jet Propulsion Laboratory. Ostro led radar observations of numerous asteroids, as well as the moons of Jupiter and Saturn, Saturn's rings, and Mars and its satellites. As of May 2008, Ostro and his collaborators had detected 222 near-Earth asteroids (including 130 potentially hazardous objects and 24 binaries) and 118 main belt objects with radar. He died December 15, 2008 due to complications related to cancer. He has been remembered fondly by his colleagues for both his personal and professional contributions.
Dr. Ostro received an A.B. in liberal arts and a B.S. in ceramic science from Rutgers University in 1969, a Master's in engineering physics from Cornell University in 1974, and his Ph.D in planetary science from the Massachusetts Institute of Technology in 1978. At MIT, Ostro was advised by Gordon Pettengill and Irwin I. Shapiro and studied the radar scattering properties of Saturn's rings and the Galilean satellites using the Arecibo Observatory.
