Hidden ice beneath Mars’ surface may mark the spot where humanity first sets foot on the Red Planet. A newly identified region on Mars may hold the key to future human landings. Researchers found evidence of water ice less than a meter beneath the surface, close enough to be harvested for water, oxygen, and fuel. The location strikes a rare balance between sunlight and cold, helping preserve the ice. It could also offer clues about whether Mars once supported life.

Before humans can make the long trip to another world, scientists must identify a safe and practical place to land. New research led by a University of Mississippi scientist suggests one region on Mars may meet many of the requirements for future human missions.

NASA has big plans for returning astronauts to the Moon in 2024, a stepping stone on the path to sending humans to Mars. But where should the first people on the Red Planet land?

A new paper published in Geophysical Research Letters will help by providing a map of water ice believed to be as little as an inch (2.5 centimeters) below the surface.

Water ice will be a key consideration fo...

1. Type II features are the most common of Ceres’ landslides and look similar to deposits left by avalanches on Earth. This one also looks similar to TV’s Bart Simpson. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA, taken by Dawn Framing Camera
2. Type I landslides on Ceres are relatively round, large and have thick “toes” at their ends. They look similar to rock glaciers and icy landslides in Earth’s arctic. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA, taken by Dawn Framing Camera
3. Ceres’ Type III features appear to form when some of the ice is melted during impact events. These landslides at low latitudes are always found coming from large-impact craters. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA, taken by Dawn Framing Camera

Massive landslides, similar to those found on Earth, are...

#Image2: Crater No. 1, whose interior has a large region in permanent darkness (a). In the weak scattered light, the framing cameras can make out bright deposits of ice (b). Crater No. 2 with its dark region is shown in Figures (c) to (e). The ice shown in (d) extends into the region with direct illumination (e). © Nature Astronomy
