Images of locations in Gale Crater taken from orbit around Mars reveal evidence of erosion in recent geological times and development of small scarps, or vertical surfaces.

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows the western wall of a small pit that is located along the floor of a larger trough in Coprates Catena. Dark layers line the bottom; li...

Lucus Planum is a part of the enigmatic Medusa Fossae Formation, a broad, soft, and easily eroded deposit. Here this deposit is thin and considerably rougher than elsewhere, implying that it is hea...

These barchan (crescent-shaped) sand dunes are found within the North Polar erg of Mars.

The High-Resolution Imaging Science Experiment aboard NASA's Mars Reconnaissance Orbiter provides this view of Olympus Mons, the tallest known volcano in the solar system.

A rippled dune front in Herschel Crater on Mars moved an average of about one meter (about one yard) between March 3, 2007 and December 1, 2010, as seen in these images from NASA's Mars Reconnaissa...

This sequence of seven images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows wind-caused changes in the parachute of NASA's Mars Sci...

This crater is named for G. Edward Danielson, Jr. who was instrumental in the development of a series of Mars cameras, from Mariner 4 launched in 1964 to the Mars Global Surveyor launched in 1996.

This enhanced image shows the inside of a rimless pit about 310 meters (1,017 feet) in diameter, northwest of the mountain Ascraeus Mons in the northern hemisphere of Mars.

The Eridania basin of southern Mars is believed to have held a sea about 3.7 billion years ago, with seafloor deposits likely resulting from underwater hydrothermal activity. This graphic shows est...

This Mars map shows variations in thickness of the planet's crust, the relatively thin surface layer overlying the mantle of the planet. It shows unprecedented detail derived from new mapping of va...

The Mars Reconnaissance Orbiter has seen many places on the planet. One of the most interesting is one of the great canyon systems on Mars.

Dust-Mantled Topography near Zephyria Tholus

Artist's concept of Mars Reconnaissance Orbiter approaching Mars.

This is a small volcano superimposed on the flanks of a larger one of the Cerberus Tholi.

This field of dunes lies on the floor of an old crater in Noachis Terra, one of the oldest places on Mars.

Eridania Basin Light-Toned Outcrops

This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta, the material thrown out of the crater when a meteorite hit Mars.

Lighter colors represent higher elevation in this image of Jezero Crater on Mars, the landing site for NASA's Mars 2020 mission. The oval indicates the landing ellipse, where the rover will be touc...

This diagram illustrates an interpretation for the origin of some deposits in the Eridania basin of southern Mars as resulting from seafloor hydrothermal activity more than 3 billion years ago.

Caught in Action: This image shows avalanches on North Polar Scarps.

This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today.
