The young Mars would have had enough water to cover its entire surface in a liquid layer about 140 m deep, but it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 km.

These illustrations show three versions of a rocky planet with different amounts of internal heating from radioactive elements. The middle planet is Earth-like, with plate tectonics and an internal dynamo generating a magnetic field. The top planet, with more radiogenic heating, has extreme volcanism but no dynamo or magnetic field. The bottom planet, with less radiogenic heating, is geologically ‘dead,’ with no volcanism.

This colorized radar image, taken by NASA’s Cassini orbiter on February 15, 2005, shows a 60-km (37-mile) wide crater on Titan. The appearance of the crater and the extremely bright (hence rough) blanket of material surrounding it is indicative of an origin by impact, in which a hypervelocity comet or asteroid, in this case, roughly 5-10 km (3-6 miles) in size, slammed into the surface of the moon. The bright surrounding blanket is debris, or ejecta, thrown out of the crater. The asymmetric appearance of this ejecta blanket could be an effect of atmospheric winds associated with the impact itself. Although clearly formed by impact, the feature lacks a central peak, suggesting that it has been eroded or otherwise modified after formation. Rainfall, wind erosion, and softening of the solid material in which the crater formed are all possible processes that might have altered this impact feature. Image credit: NASA / JPL-Caltech / ASI.

This image shows a triple crater in Noachis Terra, Mars. The largest crater measures 45 km across, and the smallest 28 km. There are also signs of other sizeable craters, such as the round patches of sunken surface seen to the top right and bottom left. This image comprises data gathered by ESA’s Mars Express using its High Resolution Stereo Camera (HRSC) on August 6, 2020. This image was created using data from the nadir and color channels of the HRSC. The nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface. North is to the right. Image credit: ESA / DLR / FU Berlin / CC BY-SA 3.0 IGO.
