Researchers have found deposits of impact glass preserved in Martian craters, including Alga Crater, shown here. The detection is based on data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) on NASA's Mars Reconnaissance Orbiter.

These dunes in Richardson Crater are still frost covered in this image captured by NASA's Mars Odyssey. As spring deepens the frost will sublimate and the dark dunes will appear.
