103737 Curbeam           Discovered 2000 Feb. 5 by M. W. Buie at Kitt Peak.
Robert Lee Curbeam Jr (b. 1962) is a retired NASA astronaut and the first person to perform four spacewalks on a single mission. While in space Curbeam helped to fix an solar panel and install a new truss in the International Space Station. He has totaled more than 37 days in space and 45 hours on spacewalks.
