New Study Shows Mars Gullies Not Formed by Liquid Water

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 evidence will allow researchers to further narrow theories about how Martian gullies form, and reveal more details about Mars’ recent geologic processes. Scientists use the term “gully” for features on […]

Mars Canyons Study Adds Clues about Possible Water

A newly published study reveals clues about possible water at seasonally dark streaks on Mars. The study investigated thousands of these warm-season features in the Valles Marineris region near Mars’ equator. Some of the sites displaying the seasonal flows are canyon ridges and isolated peaks, ground shapes that make it hard to explain the streaks […]

New Image Shows Frosted Dunes on Mars

NASA’s Mars Reconnaissance Orbiter captured this image of sand dunes on Mars. Sand dunes cover much of this terrain, which has large boulders lying on flat areas between the dunes. It is late winter in the southern hemisphere of Mars, and these dunes are just getting enough sunlight to start defrosting their seasonal cover of […]

Clues about Volcanoes Under Ice on Ancient Mars Revealed

New evidence from NASA’s Mars Reconnaissance Orbiter suggests that volcanoes erupted beneath an ice sheet on Mars billions of years ago. The research about these volcanoes helps show there was extensive ice on ancient Mars. It also adds information about an environment combining heat and moisture, which could have provided favorable conditions for microbial life. […]

Phobos as Observed by MAVEN's Imaging Ultraviolet Spectrograph

New observations from NASA’s MAVEN Mission has scientists closer to solving the mystery of how Mars’ moon Phobos formed. In late November and early December 2015, NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission made a series of close approaches to the Martian moon Phobos, collecting data from within 300 miles (500 kilometers) of the […]

Rover Curiosity Tastes Scooped, Sieved Sand

NASA’s Curiosity Mars Rover continues its campaign to study active sand dune on Mars, scooping and analyzing samples. At its current location for inspecting an active sand dune, NASA’s Curiosity Mars rover is adding some sample-processing moves not previously used on Mars. Sand from the second and third samples the rover is scooping from “Namib […]

New NASA Image Shows the Surface of Mars

This newly released image shows radial troughs on the surface of Mars. Mars’ seasonal cap of carbon dioxide ice has eroded many beautiful terrains as it sublimates (goes directly from ice to vapor) every spring. In the region where the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter took this image, […]

New Image from the Mars Orbiter

This highly detailed image from NASA’s Mars Reconnaissance Orbiter shows boulders on the surface of Mars. The striking feature in this image, acquired by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter on March 19, 2014, is a boulder-covered landslide along a canyon wall. Landslides occur when steep slopes fail, […]

NASA Explains Loss of Carbon in Martian Atmosphere

New research from Caltech and NASA offers an explanation for the “missing” carbon in the Martian atmosphere, showing that a transition from a moderately dense atmosphere to the current thin one is entirely possible. Mars is blanketed by a thin, mostly carbon dioxide atmosphere — one that is far too thin to keep water from […]

New Image of Schiaparelli Basin from Mars Express

This image from ESA’s Mars Express features the small crater embedded in the northwestern rim of the Schiaparelli impact basin. All around is evidence for past water and the great martian winds that periodically blow. A 42 km-wide impact crater and numerous smaller craters straddle the northwestern rim of the 460 km-diameter Schiaparelli basin in […]
