HiRISE: Cluster of recent impacts

The dark spots in this enhanced-color infrared image are the recent impact craters that occurred in the Tharsis region between 2008 and 2014. These impact craters were first discovered by the Mars Context Camera (or CTX, also onboard the Mars … Continue reading

MRO spots Schiaparelli impact scar, parachute

NASA’s Mars Reconnaissance Orbiter has identified new markings on the surface of the Red Planet that are believed to be related to ESA’s ExoMars Schiaparelli entry, descent and landing technology demonstrator module. Schiaparelli entered the martian atmosphere at 14:42 GMT … Continue reading

Hunting ice cap ‘spiders’ through citizen science

Ten thousand volunteers viewing images of Martian south polar regions have helped identify targets for closer inspection, yielding new insights about seasonal slabs of frozen carbon dioxide and erosional features known as “spiders.” From the comfort of home, the volunteers … Continue reading

Rise and fall of Martian lakes

There is a wealth of evidence, collected over the past few decades, suggesting liquid water was abundant in the early history of Mars. However, the size, evolution, and duration of standing bodies of water such as lakes on Mars’ surface … Continue reading

Help wanted: categorizing south polar features

Science-team members for NASA’s Mars Reconnaissance Orbiter are soliciting help from the public to analyze exotic features near the south pole of Mars. By categorizing features visible in images from the orbiter’s Context Camera (CTX), volunteers are using their own … Continue reading

Gale Crater’s icy hydrological cycle

Gale Crater was once home to glaciers and other features of an icy hydrological system, says a team of scientists led by Alberto Fairén (Centro de Astrobiología in Spain and Cornell University). They base their work on images captured with the … Continue reading

Mars dust devils travel much faster than surface winds blow

Extending earlier work, a team of Mars scientists led by Dennis Reiss (Westfälische Wilhelms-Universität, Germany) has made simultaneous (or near-) observations of dust devil speeds using cameras on NASA’s Mars Reconnaissance Orbiter. The cameras include CRISM, CTX, and HiRISE. The … Continue reading

Aeolis Serpens, Mars’ longest sinuous ridge, is an ancient riverbed

A linear ridge that winds for more than 200 kilometers (120 miles) through part of South Australia was a river channel roughly 10 million years ago. After the paleoriver stopped flowing, silica-rich groundwater seeped into the riverbed, cementing its sediments.
