Named in memory of Thomas O. Paine, administrator of NASA from 1968 to 1970. He led the American space agency to its greatest achievement - the Apollo 11 mission, in which humans first walked on the moon. During his tenure at NASA, Paine laid the groundwork for the Apollo-Soyuz {see planet  (2228)} test project, which marked the first joint flight of American and Soviet space travelers. In 1985 he was called again to serve the space program as chairman of the National Commission of Space, where he laid out his vision of humanity’s future as a spacefaring species. Tom Paine’s most enduring contribution may be the inspiration he has provided that will take humans beyond the moon to the frontier of Mars. (M 21133) _ _.
