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.

A noticeable feature of the Atlantis basin is the several hundred mesas and small peaks strewn ‘chaotically’ across its roughly 200-km expanse. The uppermost layer of these elevated areas consists of light-colored material. Spectroscopic measurements have shown these consist of phyllosilicates, minerals produced in the presence of water.

This view from Cassini looks toward Dione, with giant Saturn and its rings in the background, just prior to the mission’s final close approach to the moon on August 17. The view was acquired at distances ranging from approximately 106,000 miles (170,000 km) to 39,000 miles (63,000 km) from the icy moon and at a Sun-Dione-spacecraft, or phase, angle of 35 degrees. At lower right is the large, multi-ringed impact basin Evander, which is about 220 miles (350 km) wide. The canyons of Padua Chasma, features that form part of Dione’s bright, wispy terrain, reach into the darkness at left. Scientists combined nine visible light images to create this mosaic view: eight from Cassini’s narrow-angle camera and one from the wide-angle camera, which fills in an area at lower left. The scene is an orthographic projection centered on terrain at 0.2 degrees north latitude, 179 degrees west longitude on Dione. An orthographic view is most like the view seen by a distant observer looking through a telescope. North on Dione is up. Image credit: NASA / JPL-Caltech / Space Science Institute.

$This image from NASA’s Cassini spacecraft shows a part of Dione’s surface that is covered by linear, curving features, called chasmata. The Voyager spacecrafts observed Dione in 1980 showing a complex surface structure, with wispy features on its trailing hemisphere. The nature of these features was unclear until 2004, when the Cassini spacecraft showed that they weren’t surface deposits of frost, as some had suspected, but rather a pattern of bright icy cliffs among myriad fractures. One possibility is that this stress pattern may be related to Dione’s orbital evolution and the effect of tidal stresses over time. This view looks toward the trailing hemisphere of Dione. Cassini obtained the image with its narrow-angle camera on April 11, 2015. The view was acquired at a distance of 68,000 miles (110,000 km) from Dione. North on Dione is up.

The mysterious bright spots on Ceres lie in the Occator crater, which is about 60 miles (90 km) across and two miles (4 km) deep. This image comes from the animation, generated using data from NASA’s Dawn spacecraft; vertical relief has been exaggerated by a factor of five; exaggerating the relief helps scientists understand and visualize the topography much more easily, and highlights features that are sometimes subtle.

The asteroid 31 Euphrosyne glides across a field of background stars in this time-lapse view from NASA’s WISE spacecraft. WISE obtained the images used to create this view over a period of about a day around May 17, 2010, during which it observed the asteroid four times. The moving asteroid appears as a string of orange dots because it is much cooler than the distant background stars. Stars have temperatures in the thousands of degrees, but the asteroid is cooler than room temperature. Thus the stars are represented by shorter wavelength blue colors in this view, while the asteroid is shown in longer wavelength reddish colors. Image credit: NASA / JPL-Caltech.
