High-resolution photos of lava flows on Mars reveal coiling spiral patterns that resemble snail or nautilus shells. Such patterns have been found in a few locations on Earth, but never before on Mars. The discovery, made ...
HiRISE periodically images the Curiosity rover and its surroundings, monitoring for changes such as from active dunes.
(Phys.org) —Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released today.
(Phys.org)—During the 10 minutes before the NASA Mars Science Laboratory spacecraft entered the Martian atmosphere to deliver the rover Curiosity to the surface, the spacecraft shed its cruise stage, which had performed ...
(PhysOrg.com) -- New images from the HiRISE experiment detail patterns of dust carried by gas from beneath the seasonal ice cap.
Sand dunes cover much of this terrain, which has large boulders lying on flat areas between the dunes.
Alluvial fans are gently-sloping wedges of sediments deposited by flowing water. Some of the best-preserved alluvial fans on Mars are in Saheki Crater, an area that has been imaged many times previously.
Among the many discoveries by NASA's Mars Reconnaissance Orbiter since the mission was launched on Aug. 12, 2005, are seasonal flows on some steep slopes. These flows have a set of characteristics consistent with shallow ...
Images taken by the UA-led HiRISE mission reveal that the setting of the best-selling novel "The Martian" is far from being the featureless plain described in the book.
This image of an area on the surface of Mars, approximately 1.5 by 3 kilometers in size, shows frosted gullies on a south-facing slope within a crater.
