This image shows the seasonal flows in Valles Marineris on Mars, called the Repetitive Slope Line, or RSL. These Martian landslides appear on cliffs during the spring and summer.
This artist’s illustration shows the ExoMars Trace Gas Orbiter orbiting Mars. The probe detected a layer of glowing green oxygen in the Martian atmosphere.
NASA’s Curiosity Mars probe took a selfie shortly before completing its steepest climb yet on the surface of Mars until the ascent of the Greenhigh Piedmont, which tilted the rover by 31 degrees.
NASA’s Curiosity probe captured the highest resolution panorama, including more than a thousand images and 1.8 billion pixels, of the surface of Mars between November 24 and December 1, 2019.
The cloud in the center of the image is actually a dust tower that occurred in 2010 and was captured by the Mars Reconnaissance Orbiter. The blue and white clouds are water vapor.
This perspective of the hemisphere in the Valles Marineris from July 9, 2013, is actually a mosaic of 102 Viking Orbiter images. In the center is the Vallis Marineris Valley System, which is more than 2000 km long and 8 km deep.
The NASA Curiosity probe took this selfie on October 11, 2019, in the Glen Eve.
The InSight lander was photographed from above by the Mars Reconnaissance Orbiter.
Is that cakes and cream on Mars? No, they are just polar dunes, dusted with ice and sand.
The European Space Agency’s Mars Express mission captured this image of the Korolev crater, which is more than 50 miles wide and filled with water ice, near the North Pole.
A recent photo taken by the Curiosity Wagon shows its current location known as “Teal Ridge”. The rover is studying mud unit in this area.
The cooling lava helped preserve the imprint of where the dunes moved across southeastern Mars. But it also appears to be a “Star Trek” icon.
NASA’s InSight lander used a camera on its robotic arm to capture this sunset on Mars on April 25.
InSight seismograph records a first “swamp earthquake” on April 6, 2019.
Image of a river channel preserved on the surface of Mars, captured by a satellite in orbit, with color overlay to show different altitudes. Blue is low, yellow is high.
This is the first selfie of NASA Insight on the surface of Mars. Solar panels and deck displays. On deck are its scientific instruments, weather sensing arms and a UHF antenna.
Rover can take selfies, too. This selfie shows a Curiosity Mars spacecraft at the Quela drill site in Murray Buttes on Lower Sharp Mountain.
Mars is a far cry from a flat and arid landscape. Nili Patera is an area on Mars where dunes and ripples move rapidly. HiRISE, aboard the Mars Reconnaissance Orbiter, continues to monitor this area every two months to see changes to the seasonal and annual time scales.
What do blueberries do on Mars? These small stones, rich in mineral hemates, are found near the Fram Crater, which NASA’s Opportunity spacecraft visited in April 2004. The displayed area is 1.2 inches wide. The view comes from the microscopy device on the Opportunity’s robotic arm, with color information added from the rover’s panoramic camera. These minerals indicate that Mars had a water past.
Mars is known to have dust storms surrounding the planet. These images, taken in 2001 from the NASA Global Mars Survey Orbiter, show a drastic change in the appearance of the planet as the haze from dust storm activity spread across the globe.
Curiosity took pictures on September 9, 2015, of Mount Sharp, a chain of hills rich in hematite, a plain filled with clay minerals to create complex, high-round compositions of sulfate minerals. The shifting mineralogy of these Sharp Mountain layers indicates a changing environment in early Mars, even though they all involved exposure to water billions of years ago.
HiRISE has captured layered sediments and a shiny ice sheet at the Arctic of Mars.
This image, which collects data from two devices aboard NASA’s Mars Global Surveyor, depicts an orbital view of Mars’ north polar region. The ice-rich polar cap is 621 miles wide, and dark bands are in deep basins. To the right of center, a large valley, Chasma Boreale, nearly bisects the ice cap. The Chasma Boreale is about 1.2 miles long in the famous Grand Canyon in the United States.
Although Mars is not geologically active like Earth, its surface features have been heavily shaped by the wind. Wind carved features like these, called yardangs, are common on the Red Planet. On the sand, the winds form small ripples and dunes. In the thin atmosphere of Mars, the light is not scattered much, so the shadows cast by the yarding are sharp and dark.
From its elevated position on a hillside, Opportunity recorded this image of a Mars dust demon as it curled across the valley below. The view looks at rover tracks to the north-facing slope at Knudsen Ridge, which forms part of the southern edge of the Marathon Valley.
HiRISE captured this image of a kilometer-sized crater in the southern hemisphere of Mars in June 2014. The crater shows frost on all south-facing slopes in late winter as Mars approaches spring.
The Mars Reconnaissance Orbiter used its HiRISE camera to obtain this view of an area of unusual texture on the south floor of Gale Crater.
This image taken by HiRISE camera on November 19, 2013 is dominated by a new and exciting impact crater. The crater extends nearly 100 feet and is surrounded by a large burst area with rays. Because the terrain in which the crater was formed is dusty, the new crater appears blue in the image enhancement, due to the removal of reddish dust in that area.
Opportunity used its panoramic camera to record this horizontal view eastward on October 31, 2010. Part of the eastern edge of Endeavor Crater, about 19 miles in the distance, can be seen over the Meridiani Planum.
In this artist’s concept of NASA’s Insight lander on Mars, layers beneath the planet’s surface can be seen below and dust devils can be seen in the background.
The two largest earthquakes detected by NASA’s InSight appear to have originated in a region of Mars called Cerberus Fossae. Scientists have previously discovered signs of tectonic activity here, including landslides. This photo was taken by the HiRISE Camera on NASA’s Mars Reconnaisance Orbiter.
