This composite image looking toward the higher regions of Mount Sharp was taken on September 9, 2015, by NASA's Curiosity rover. In the foreground—about 2 miles (3 kilometers) from the rover—is a long ridge teeming with hematite, an iron oxide.

While NASA imagery has shown evidence of ancient rivers and lakes on Mars that transitioned to dry dunes, uncertainty remains over the timing of the environmental changes that may have contributed to these shifts. Now, data collected by NASA’s Curiosity rover has revealed that individual crystals in the iron oxide hematite can be used as a mineralogical marker of changes to Mars’ ancient climate.

A close-up view of a portion of a "relatively fresh" crater, looking southeast, as photographed during the third Apollo 15 lunar surface moonwalk. A new NASA study of its Apollo lunar soils clarifies the Moon’s record of meteorite impacts and timing of water delivery. These findings place upper bounds on how much water meteorites could have supplied later in Earth’s history.
