NASA’s Mars Reconnaissance Orbiter (MRO) demonstrates an impact crater that looks like a tadpole because of the valley that was carved by water that used to fill it. It is often difficult to differentiate between inlet and outlet channels, but water always flows downhill. In this particular occasion, scientist can deduce that water is flowing outward because they have the necessary terrain-height information. When studying these images in detail, scientists may understand a better understanding of the strength of the flooding water that carved the channels, and better understand the history of water activity in this region of Mars. The map is projected at a scale of 25 centimeters (9.8 inches) per pixel. The original image scale is 32.9 centimeters (12.9 inches) per pixel. Objects on the order of 99 centimeters (38.9 inches) across are resolved. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp, Boulder, Colorado. NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA’s Science Mission Directorate, Washington.
