Western flank of Elysium Mons.

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

Bacolor Crater is a magnificent impact feature about 20 kilometers (12 miles) wide.

This image captured by NASA's 2001 Mars Odyssey spacecraft shows 'streamers' of clouds created by katabatic winds at the north polar cap.

On the southwest edge of the immense volcanic region of Tharsis, lava from its giant volcanoes flowed down to meet the old cratered landscape of Terra Sirenum.

When the Mars Exploration Rover, Opportunity, landed on Meridiani Planum in January 2004, it quickly found what it had been sent from Earth to find: evidence of liquid water in the Martian past.

A sea of dark dunes, sculpted by the wind into long lines, surrounds the northern polar cap covering an area as big as Texas.

Snow falls and ice and frost form on Mars, too. NASA's spacecraft on and orbiting the Red Planet reveal the similarities to and differences from how we experience winter on Earth.  

Color coding in this map of a far-northern site on Mars indicates the change in nighttime ground-surface temperature between summer and fall. This site, like most of high-latitude Mars, has water i...

A lunar eclipse, a solar eclipse and Mars has a close encounter with a comet.

How do you converse with a robot nearly one hundred million miles away? In this video, Odyssey team members describe communications with the 2001 Mars Odyssey spacecraft using the antennas of the D...

At the time this video was released, the Odyssey team had successfully completed the third trajectory correction maneuver to adjust the spacecraft's flightpath toward its final aimpoint for entry i...

This view of an area about 140 kilometers (about 90 miles) wide in the Meridiani Planum region of Mars shows the region around NASA's Mars Exploration Rover Opportunity.

Fans and ribbons of dark sand dunes creep across the floor of Bunge Crater in response to winds blowing from the direction at the top of the picture. The frame is about 14 kilometers (9 miles) wide.

NASA's NEOWISE mission detected comet C/2013 A1 Siding Spring on July 28, 2014, less than three months before this comet's close flyby of Mars on Oct. 19. This merging of multiple images presents t...

Large fractures have formed 'steps' in this region of Tempe Terra.

Five decades of successful NASA missions to the Red Planet, 1965-2015.

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

In Ares Vallis, teardrop mesas extend like pennants behind impact craters, where the raised rocky rims diverted the floods and protected the ground from erosion.

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...

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.
