This image focuses on a section of Aurorae Chaos on Mars. Vast volumes of water once flooded through this deep chasm on the planet that connects Valles Marineris to the planet’s northern lowlands. The image was taken by Mars Express’ High Resolution Stereo Camera on July 16, 2015. The image was acquired using the nadir channel of the camera, which is directed vertically down onto the surface of Mars. Image credit: ESA / DLR / FU Berlin / CC BY-SA 3.0 IGO.

This mini-panorama was taken by NASA’s Spirit rover on August 23, 2005, just as the rover finally completed its intrepid climb up Husband Hill. The summit appears to be a windswept plateau of scattered rocks, little sand dunes and small exposures of outcrop. The approximate true-color view spans about 90 degrees and consists of images obtained by the rover’s panoramic camera during 18 individual pointings. Image credit: NASA / JPL-Caltech / Cornell.

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.
