16035 Sasandford           Discovered 1999 Mar. 24 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Astronomer and meteoriticist Scott Alan Sandford (b. 1957), a researcher at NASA's Ames Research Center, studies the connections between interstellar chemistry and the materials, particularly organics, found in meteorites. The name was suggested by D. P. Cruikshank.
