At the time the image was taken, the spacecraft was about 17,098 miles from the cloud tops of the planet. Closer to the planet, the Galilean moon of Io can be seen. In the distance (to the left), another on of Jupiter’s Galilean moons, Europa, is visible. Credit: NASA/JPL-Caltech/SwRI/MSSS/Roman Tkachenko
Observing images of craters on Mars provides scientists insight into the water that carved them and the Red Planet's history of water activity.

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
