Surface features on Mars indicate that large amounts of water may have existed on the martian surface in the past. Where has the water gone? In his Perspective, Bell highlights the reports by Boynton et al., Feldman et al., and Mitrofanov et al., who have analyzed initial data from the Mars Odyssey mission. The results indicate that there may be large subsurface water ice deposits, especially toward the poles of our neighboring planet.
