Reull Vallis, located in Mars' cratered southern hemisphere, flows for over 1,000 km (about 620 miles) toward the Hellas basin. This NASA Mars Odyssey image shows a portion of the channel with its enigmatic lineated floor deposits.

This image from NASA's Mars Odyssey is located near the equator and the prime meridian of Mars in a region called Terra Meridiani. This is a unique area of Mars that displays layers of material that appear to be in the process of being stripped away.

Like drippings from a candle, these lava flows on the flank of Olympus Mons volcano, seen in this image from NASA's Mars Odyssey spacecraft, demonstrate how it became the largest volcano in the solar system.

This image from NASA's Mars Odyssey shows deposits in a crater located in Arabia Terra. Arabia is generally dust covered and dark streaks or dust avalanches are present in the crater walls.

This NASA Mars Odyssey image shows parts of the dissected and eroded remnants of an impact crater rim and volcanic material located north of Apollinaris Patera near the southern highlands - northern lowlands dichotomy on Mars.

This image from NASA's Mars Odyssey spacecraft shows the eastern portion of a region on Mars called Hesperia Planum. Immediately visible in the image is the dark barchan type dunes that are being blown against the southeast wall of the crater.

This NASA Mars Odyssey image of rounded hills and ridges in Arcadia Planitia shows a very intriguing geomorphic feature that may be attributed to the presence of an icy-rock mixture of material.

Located in Arabia Terra, the crater shown in this image from NASA's Mars Odyssey spacecraft is known as Henry Crater. Like many other craters on Mars, the interior of Henry Crater is filled with a layered deposit.

The Cydonia region on Mars, seen in this image from NASA's Mars Odyssey spacecraft, straddles the boundary between the bright, dusty, cratered highlands to the southeast and the dark, relatively dust-free, lowland plains to the west.

This NASA Mars Odyssey image was taken during winter in the southern hemisphere, meaning that the usually cloudy Hellas Basin is relatively free from clouds.

This image from NASA's Mars Odyssey shows the cratered highlands of Terra Cimmeria. The image contains several long troughs of Sirenum Fossae running primarily from left to right. These features are parallel to semi-parallel fractures called graben.

This image from NASA's Mars Odyssey shows a region called Terra Sirenum in Mars' southern hemisphere named for the Sea of the Sirens from Greek Mythology. This is not a sea, however, but a relatively dusty, high albedo region of Mars.

This image from NASA's Mars Odyssey is of a region of Mars called Tempe Terra, which is located between the topographically high Tharsis Region and Acidalia Planitia, a large low albedo region of in the Martian northern hemisphere.

With a diameter of roughly 2,000 km (1,243 miles) and a depth of over 7 km (more than 4 miles), the Hellas Basin, shown in this image from NASA's Mars Odyssey spacecraft, is the largest impact feature on Mars.

This image from NASA's Mars Odyssey spacecraft covers part of Tithonium Chasma, which is part of the Valles Marineris system of canyons that stretch for thousands of kilometers.

An isolated mesa east of the Phlegra Montes in northeastern Elysium Planitia has a cracked surface that, combined with its overall shape, gives the appearance of a giant loaf of bread in this image from NASA's Mars Odyssey spacecraft.

Much of the northern lowlands of Mars are thought to be relatively young volcanic flows with varying amounts of windblown dust cover. The lack of impact craters in this image from NASA's Mars Odyssey spacecraft indicate the young age of the surface.

The force of moving water from a flood carved these teardrop-shaped islands within Granicus Valles, imaged here by NASA's Mars Odyssey spacecraft. The orientation of the islands can be used as an indicator of the direction the water flowed.

In this region of the Olympus Mons aureole, located to the southwest of the volcano, the surface has been eroded by the wind into linear landforms called yardangs, which can be seen in this image from NASA's Mars Odyssey spacecraft.

Located north of Olympus Mons and west of Alba Patera, Acheron Fossae, seen in this NASA Mars Odyssey image, provides a record of early tectonic activity in the Tharsis region.

This scene from NASA's Mars Odyssey spacecraft of the dust covered plains of eastern Arabia Terra portrays a range of geological time. Three craters at the center of the image capture some of this range.

Palos Crater, seen in this NASA Mars Odyssey image, has been suggested as a future landing site for Mars missions because it may contain lake deposits. This crater has a channel called Tinto Vallis, which enters from the south.
