This map of Mars indicates locations of new craters that have excavated ice (blue) and those that have not (red). Albedo information comes from NASA's Mars Odyssey orbiter, and the map comes from NASA's Mars Global Surveyor orbiter.
Fresh Crater Exposing Buried Ice on Mid-Latitude Mars
The image is an excerpt from an observation from NASA's Mars Reconnaissance Orbiter showing a meteorite impact that excavated this crater on Mars exposed bright ice that had been hidden just beneath the surface at this location.
This pair of maps based on albedo information from NASA's Mars Odyssey orbiter and topographical information from NASA's Mars Global Surveyor orbiter indicates locations of confirmed sites of recurrent slope linea on Mars.
Seasonal Changes in Dark Marks on an Equatorial Martian Slope
These images from NASA's Mars Reconnaissance Orbiter show how the appearance of dark markings on Martian slope changes with the seasons. The marks, called recurrent slope linea extend down slopes during warmer months.
This image from NASA's Mars Reconnaissance Orbiter includes an especially long example of a type of dark marking that advances down some Martian slopes in warmer months and fades away in cooler months.
This frame from a movie was captured by a star tracker camera on NASA's Jupiter-bound Juno spacecraft. It was taken over several days as Juno approached Earth for a close flyby that would send the spacecraft onward to the giant planet.
During its close flyby of Earth, NASA's Jupiter-bound Juno spacecraft listened for a coordinated, global transmission from amateur radio operators using its radio and plasma wave science instrument, known as Waves.
This mosaic of images from the Mast Camera onboard NASA's Curiosity Mars rover shows a series of sedimentary deposits in the Glenelg area of Gale Crater, from a perspective in Yellowknife Bay looking toward west-northwest.
Radiation Exposure Comparisons with Mars Trip Calculation
Measurements with the MSL's RAD on NASA's Curiosity Mars rover during the flight to Mars and now on the surface of Mars enable an estimate of the radiation astronauts would be exposed to on an expedition to Mars.
Micrograys are unit of measurement for absorbed radiation dose. The vertical axis is in micrograys per day. The RAD instrument on NASA's Curiosity Mars rover monitors the natural radiation environment at the surface of Mars.
Volatiles Released by Heating Sample Powder from Martian Rock 'Cumberland'
This image graphs four gases released ('evolved') when powdered rock from the target rock 'Cumberland' was heated inside the Sample Analysis at Mars (SAM) instrument suite on NASA's Curiosity Mars rover.
Clay Mineral Structure Similar to Clays Observed in Mudstone on Mars
This schematic shows the atomic structure of the smallest units that make up the layers and interlayer region of clay minerals. This structure is similar to the clay mineral in drilled rock powder collected by NASA's Curiosity Mars rover.
Erosion Patterns May Guide Mars Rover to Rocks Recently Exposed
These two images come from the HiRISE camera on NASA's Mars Reconnaissance Orbiter. Images of locations in Gale Crater taken from orbit around Mars reveal evidence of erosion in recent geological times and development of small scarps, or vertical surfaces
Possible Extent of Ancient Lake in Gale Crater, Mars
This illustration depicts a concept for the possible extent of an ancient lake inside Gale Crater. The base map combines image data from the Context Camera on NASA's Mars Reconnaissance Orbiter and color information from Viking Orbiter imagery.
View of Yellowknife Bay Formation, with Drilling Sites
This mosaic of images from NASA's Curiosity shows geological members of the Yellowknife Bay formation, and the sites where Curiosity drilled into the lowest-lying member, called Sheepbed, at targets 'John Klein' and 'Cumberland'.
The rock 'Ithaca' is shown here with a rougher lower texture and smoother texture on top, and appears to be a piece of the local sedimentary bedrock protruding from the surrounding soil in Gale Crater as seen by NASA's Curiosity Mars rover.
Target for 100,000th Laser Shot by Curiosity on Mars
Since landing on Mars in August 2012, NASA's Curiosity Mars rover has fired the laser on its Chemistry and Camera (ChemCam) instrument more than 100,000 times at rock and soil targets up to about 23 feet (7 meters) away.
