'Today's Mars Photo is of Holden and Eberswalde Crater as taken by the European Space Agency's (ESA) Mars Express Orbiter. Holden crater is on the left and measures 140 km across, whereas Eberswalde Crater, on the right, measures 65 km in diameter. The rim of Eberswalde Crater is only intact on the right side because it was covered by the ejecta from the impact that created Holden Crater.
Mars Express recently found evidence that indicates a huge lake once existed in Eberwalde Crater. This photo gives some perspective as to the crater's surroundings. Click the image to see it enlarged and in high resolution.
