Exposure to sunlight creates telltale patterns in the polar ice cap that change over time, potentially providing insight into the climatic history of the Red Planet.
By modeling over 4 billion years of the Moon’s impact history, scientists estimate that the lunar poles may harbor billions of metric tons of subsurface ice.
Using topographic data, researchers have estimated the ages of water ice–containing craters near the Moon’s poles and ruled out volcanism as being a primary route for water delivery.
A new study ties layers in the polar deposits of Mars to changes in climate driven by orbital variations, constraining accumulation rates and further deciphering the climate history of the Red Planet.
This discovery is the latest in a growing stack of evidence pointing to the presence of an ammonia-rich water ocean beneath Pluto’s icy crust.
Researchers find that past studies underestimate the friction meltwater channels exert on glaciers by orders of magnitude.

Shallow Radar correlation of discrete units in one of the Red Planet’s largest ice reservoirs suggests that its material was emplaced as a single, regional deposit.
New radar observations and refined illumination maps reveal uneven water ice deposits twice the size of those found around the planet’s north pole, suggesting the source may be a recent comet impact.
Layered-ejecta craters on Mars that are associated with impacts into rock mixed with volatiles have been formed throughout the planet’s history indicating the long-term preservation of subsurface ice.
