What do you think this tadpole-shaped impact crater says about the water that used to fill it? Based on the terrain-height information and knowing that water always flows downhill, scientists were able to infer that the water in the tadpole crater was flowing down, and outward. The image was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on our Mars Reconnaissance Orbiter. Image credit: NASA/JPL-Caltech/Univ. of Arizona #nasa #space mars
