Abstract
When one looks for water on Mars, the most obvious targets are the ice‐capped polar regions. However, Shean found what appears to be buried water ice or an ice‐debris mix within 38 craters in the Sinus Sabaeus region near the Martian equator. While previous research has suggested that water was historically present near the equator, Mars's current climate is supposed to be inhospitable to equatorial water ice. Using satellite imagery, the author found material at the bottom of equatorial craters that is visually similar to material thought to be buried ice found elsewhere on Mars, especially in midlatitude craters (30°–60°N/S). He also found 30 additional craters where this material has been partially or completely removed, leaving traces that suggest it is composed of buried ice.
