"A Walk in the Sun" is a science fiction short story published in 1991 by Geoffrey A. Landis. It won the 1992 Hugo Award for Best Short Story, the 1992 Asimov's Reader Poll Award and was nominated for the 1992 Locus Award. The story follows Trish, the only survivor of a terrible crash landing on the moon. After regaining her senses, she contacts Earth and learns that it will be thirty days before she can be rescued. In the meantime, she depends on a wing-like solar panel to provide power to her suit's recycling facilities. While she waits for the rescue party, she has to continually walk... westward in order to stay in the sunlight.
