At 11:02 a.m. EDT on April 7, 2001, crowds watch a Boeing Delta II rocket lift off from Cape Canaveral Air Force Station, Florida, carrying NASA's 2001 Mars Odyssey spacecraft into space on its sev...

This movie shows the Martian moon Phobos as viewed in visible light by NASA's 2001 Mars Odyssey orbiter on April 24, 2019. The apparent motion is due to movement by Odyssey's infrared camera, Therm...

This animation shows how NASA's Curiosity rover communicates with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter (MRO) and Odyssey, and the European Space Agency's Mars Express....

Mars is experiencing large regional dust storms over its northern hemisphere during the past week.

Although it is 45 kilometers (28 miles) wide, countless layers of ice and dust have all but buried Udzha Crater.

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...

A vast dune field lies near the northern polar cap of Mars. Seen here in summer, the dunes have partially buried an impact crater about 1,000 meters (3,300 feet) wide.

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

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.

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...

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...

A new map of Mars' gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet. Satellites always orbit a planet's...

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 ...

West of Valles Marineris lies a checkerboard named Noctis Labyrinthus, which formed when the Martian crust stretched and fractured.

This artist's concept shows NASA's Mars orbiters lining up behind the Red Planet for their "duck and cover" maneuver to shield them fro comet dust that may result from the close flyby of comet Sidi...

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

NASA Science missions circle Earth, the Sun, the Moon, Mars and many other destinations within our solar system, including spacecraft that look out even further into our universe. The Science Fleet...

This mosaic of infrared images shows the abundance and location of hematite at Opportunity's landing site, Meridiani Planum. On Earth, hematite is a mineral that typically forms in water.

Odyssey launched on Boeing's Delta II 7925 that uses nine strap-on solid rocket motors.

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.

Mars program Chief Engineer Robert Shotwell describes Mars Odyssey's unprecedented view of comet Siding Spring as the comet sweeps by the Red Planet on Oct. 19 and how it will maneuver to take images.

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

This artist's animation shows how NASA's Curiosity rover will communicate with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter and Odyssey. As the rover descends to the surface o...

This graphic depicts the relative shapes and distances from Mars for five active orbiter missions plus the planet's two natural satellites. It illustrates the potential for intersections of the spa...
