Mars Crossing is a science fiction novel by Geoffrey A. Landis about an expedition to Mars, published by Tor Books in 2000. The novel was a nominee for the Nebula award, and won the Locus Award for best first novel in 2001.
The characters in the novel are members of the third expedition to Mars, following the failures of earlier Brazilian and American expeditions. The mission plan is based on the Mars Direct concept, where fuel is manufactured from the Martian atmosphere; the Brazilian Mars expedition selected a polar landing.
The book was released by Tor Books, a division of Macmillan USA, as a hardcover in December 2000, with the Science Fiction Book Club edition published in 2001. A paperback edition appeared in November 2001.
