Deposits of impact glass have been preserved in Martian craters, including Alga Crater, shown here. In color coding based on analysis of data from the CRISM instrument on NASA’s Mars Reconnaissance Orbiter, green indicates the presence of glass; blues are pyroxene; reds are olivine. This view shows Alga Crater’s central peak, which is about 3 miles (5 km) wide within the 12-mile (19-km) diameter of this southern-hemisphere crater. The information from CRISM is shown over a terrain model and image based on observations by the High Resolution Imaging Science Experiment (HiRISE) camera. The vertical dimension is exaggerated by a factor of two. Image credit: NASA / JPL-Caltech / JHUAPL / University of Arizona.

Thousands of supraglacial lakes form each spring and summer on top of the Greenland Ice Sheet. When they drain, they send torrents of water to the base of the ice sheet, lubricating the interface between rock and ice. That allows the ice sheet to flow faster to the ocean and discharge ice into ocean, which causes sea levels to rise faster. Image credit: Laura Stevens / Woods Hole Oceanographic Institution.
