Independent ground-based observations of the Moon confirm prior spacecraft observations that hydration at the lunar surface varies with temperature.
This month’s issue of Eos shows how scientists can sometimes get a better look at something by stepping far—much, much farther—away.
New research shows how fast the sands shift on the Red Planet and how useful imagery from different orbiting cameras can be in studies of Mars’s dunes.
A new study shows how a warm, wet climate weathered rocks on early Mars.
Mars’s aqueous past holds the answers to many questions about the Red Planet. A new study provides a tool for scouring planetary surfaces for ancient shorelines.
A new study finds that Phobos includes chunks of Martian crust.
Slope streaks of different sizes and shapes are a common feature on the surface of Mars, but scientists disagree about the mechanisms for their formation and development.
The soon-to-launch satellite will measure the height and thickness of sea ice, glaciers, ice sheets, and permafrost around the world to an unprecedentedly high precision.
Researchers use high-resolution images of Mars’s surface to look for signals of coseismic displacement.
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.
