This new HiRISE image shows a recent cluster of impacts on Mars. The dark spots in this enhanced-color infrared image are the recent impact craters…
This new HiRISE image shows dunes and gullies on the surface of Mars. Gullies are relatively common features in the steep slopes of crater walls,…
New research reveals that Mars had far too little carbon dioxide about 3.5 billion years ago to provide enough greenhouse-effect warming to thaw water ice….
ESA’s Mars Express provides a new mosaic of Mars. A new mosaic from ESA’s Mars Express shows off the Red Planet’s north polar ice cap…
NASA’s High Resolution Imaging Science Experiment (HiRISE) gets a closer look at impact ejecta on the surface of Mars. Impact ejecta is material that is…
This newly released HiRISE image shows dunes on the surface of Mars during the Martian northern summer. This dune field formed near the base of…
A new study on polygon-forming ridges on Mars examines the Medusae Fossae region straddling the planet’s equator and similar-looking networks in other regions of the…
This new image from HiRISE shows the layered bedrock in the volcanic plains of Lunae Planum. The layered bedrock in this image was brought from…
This High Resolution Imaging Science Experiment (HiRISE) image reveals the changing dunes of Wirtz Crater on Mars. The large dark feature is a classic Martian…
NASA’s Curiosity Mars Rover has examined slabs of rock cross-hatched with shallow ridges that likely originated as cracks in drying mud. “Mud cracks are the…
This newly released NASA image shows wind carved rock on the surface of Mars. The distinctively fluted surface and elongated hills in this image in…
New images from the MAVEN mission show the ultraviolet glow from the Martian atmosphere in unprecedented detail, revealing dynamic, previously invisible behavior. They include the…
Based on a historical pattern, scientists believe they can predict the occurrence of dust storms on Mars. Global dust storms on Mars could soon become…
New research from Yale University shows that rocks formed by the grinding together of other rocks during earthquakes are rich in trapped hydrogen — a…
The layered geologic past of Mars is revealed in stunning detail in new color images from NASA’s Curiosity Mars Rover, which is currently exploring the…
This newly released image from NASA’s Mars Reconnaissance Orbiter shows a portion of Lethe Vallis, an outflow channel that also transported lava. This image was…
Using data from NASA’s Mars Reconnaissance Orbiter, astronomers show that gullies on modern Mars are likely not being formed by flowing liquid water. This new…
