IMAGE: Two views of the northern hemisphere of Mars (orthographic projection centered on the north pole), both with a grey background of shaded relief. On the left, the light grey shading shows the northern ice stability zone, which overlaps with the purple shading of the SWIM study region. On the right, the blue-grey-red shading shows where the SWIM study found evidence for the presence (blue) or absence (red) of buried ice. The intensity of the colors reflect the degree of agreement (or consistency) exhibited by all of the data sets used by the project.

All eyes are on Mars, and even our home institution, the Planetary Science Institute, has gotten into the game. Last week, we announced the release of new maps showing the location of water ice on Mars. A team of scientists, featuring seven from PSI, used data from the Mars Reconnaissance Orbiter, Mars Odyssey, and Mars Global Surveyor to create these maps. The team is a part of the Subsurface Water Ice Mapping on Mars project or SWIM. Which, frankly, is a fantastic acronym.

As lead author Gareth Morgan explains: The goal of SWIM is to provide maps of potential buried ice deposits to support the selection ...
