Two sizes of ripples are evident in this December 13, 2015, view of a top of a Martian sand dune, from Curiosity. Sand dunes and the smaller type of ripples also exist on Earth. The larger ripples -- roughly 10 feet (3 m) apart -- are a type not seen on our planet nor previously recognized as a distinct type on Mars. Scale bar - 2 m (79 inches).

This image of an impact crater in the Sirenum Fossae region of Mars was taken by NASA’s Mars Reconnaissance Orbiter on March 30, 2015. The crater is approximately 3,300 feet (1-km) wide and appears relatively recent as it has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. Image credit: NASA / JPL / University of Arizona / Alfred McEwen.

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.
