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 false-color map shows the area within Gale Crater on Mars, where NASA's Curiosity rover landed on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT).

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

This image is near the southern edge of a low, broad volcanic feature called Syrtis Major.

A group of small, unnamed craters in the martian southern hemisphere is the first site captured by a group of middle school students who are operating the camera system onboard NASA's Mars Odyssey ...

This region of Terra Sabaea contains areas with high densities of small craters.

The floor of this crater in Terra Sirenum contains layered material. The layered sedimentary material on Mars is arguably the most interesting and compelling material on the planet. These layers mo...

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...

No NASA Mars orbiter has been in a position to observe morning daylight on Mars since the twin Viking orbiters of the 1970s.

Geological faulting has opened cracks in the Cerberus region that slice through flat plains and mesas alike.

These three views of the Martian moon Phobos were taken by NASA's 2001 Mars Odyssey orbiter using its infrared camera, THEMIS. Each color represents a different temperature range.

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...

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...

Wind shadow and real shadow combine to give a striking image of a comet.

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...

Just as on Earth, volcanism and tectonism are found together on Mars. Here is an example: the ridges and fractures of Claritas Fossae are affecting or perhaps hosting the volcanic flows of Solis Pl...

This series of images was taken in visible-wavelength light as the THEMIS camera on NASA's Mars Odyssey scanned across the Martian moon Phobos on Sept. 29, 2017. The apparent motion is due to progr...

A small basin (center foreground) lies below the southern rim of Melas Chasma, part of Valles Marineris.

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

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...

A dust storm continues to envelop the Red Planet and Curiosity’s labs are back in action.

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...
