Colors in this image of the Martian moon Phobos indicate a range of surface temperatures detected by observing the moon on Sept. 29, 2017, with the Thermal Emission Imaging System (THEMIS) camera o...

Getting to Mars is difficult enough -- staying there is even more challenging. Odyssey met up with Mars on October 24 02:26 UTC (October 23: 7:26 p.m. PDT/10:26 p.m.EDT).

This mosaic image of Valles Marineris - colored to resemble the martian surface - comes from the Thermal Emission Imaging System (THEMIS), a visible-light and infrared-sensing camera on NASA's Mars...

The dunes in this VIS image are located in Aonia Terra.

This computer-generated view based on multiple orbital observations shows Mars' Gale crater as if seen from an aircraft north of the crater.

This false color image shows a region with craters of different ages located at the margin of Acidalia Planitia. This image was collected during the Northern Spring season.

If a meteorite breaks in two shortly before hitting the ground, the typical bowl shape of a single impact crater becomes doubled.

Stages in the seasonal disappearance of surface ice from the ground around the Phoenix Mars Lander are visible in these images taken on Feb. 8, 2010, (left) and Feb. 25, 2010, during springtime on ...

This image shows a 90-mile-wide portion of the giant Valles Marineris canyon system. Landslide debris and gullies in the canyon walls on Mars can be seen at 100 meters (330 feet) per pixel.

The Thermal Emission Imaging System (THEMIS) camera on NASA's Mars Odyssey spacecraft has completed an unprecedented full decade of observing Mars from orbit.

This is a Mars Odyssey visible color image of an unnamed crater in western Arcadia Planitia (near 39 degrees N, 179 degrees E). The crater shows a number of interesting internal and external featur...

Sand dunes shaped like blue-black flames lie next to a central hill within an unnamed, 120-kilometer-wide (75-mile-wide) crater in eastern Arabia on Mars.

This image from NASA's Mars Odyssey shows a crater from a double impact - two meteors hitting simultaneously. The two meteors would have started as a single object and, at some point prior to impac...

These are two views of the same observation of the Martian moon Phobos taken in both infrared and visible light by NASA's 2001 Mars Odyssey orbiter using its THEMIS camera. The image was taken on A...

A "Grand Canyon of Mars" slices across the Red Planet near its equator.

This map of Mars indicates locations of new craters that have excavated ice (blue) and those that have not (red). The underlying map is based on the brightness, or albedo, of the Martian surface.

This lunar-like scene occurs along the southeastern rim of the Isidis Planitia basin. The Isidis basin is an ancient impact crater some 1200 km across that is found along the boundary separating th...

Part of a multispectral THEMIS infrared image of Nili Patera caldera on Syrtis Major has been superimposed on a high-resolution THEMIS visual image.

A small impact crater on Mars named Gratteri, 4.3 miles (6.9 km) wide, lies at the center of large dark streaks.

The dunes and dust devil tracks in this VIS image are located on the plains of Planum Chronium.

Sixteen seventh-graders at Evergreen Middle School in Cottonwood, Calif., found the Martian pit feature at the center of the superimposed red square in this image while participating in a program t...
