Although this may look like a hostile alien life form, it's actually a complex line of sand dunes near the northern ice cap of Mars.

This image combines two products from the first pointing at the Martian moon Phobos by the THEMIS camera on NASA's Mars Odyssey orbiter, on Sept. 29, 2017. Surface-temperature information from obse...

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

Echus Chasma forms the boundary between the Tharsis volcanoes to the west and Lunae Planum to the east. This region is one of both tectonically fractured rocks (top of image) and volcanic flows (mi...

Newly detailed mapping of local variations in Mars' gravitational pull on orbiters (center), combined with topographical mapping of the planet's mountains and valleys (left), yields the best-yet ma...

The channels in this VIS image are part of Tyrrhena Fossae on the northern flank of Tyrrhenus Mons.

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.

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

Hills abound in this portion of Mars located in the Vastitas Borealis region of the high northern plains. These hills are part of Scandia Colles. Note that some of the hills have aprons surrounding...

This image captured by NASA's 2001 Mars Odyssey spacecraft shows a section of Nanedi Valles, located in Xanthe Terra.

Continuing our survey of non-crater dune fields brings us to this group of dunes in Aonia Terra. The daytime IR illustrates the warmth of the dune material compared to the surrounding materials.

This rainbow-colored map shows underground water ice on Mars. Cool colors are closer to the surface than warm colors; black zones indicate areas where a spacecraft would sink into fine dust; the ou...
