New Image of Wind Carved Rock on Mars

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 Medusae Fossae on Mars are caused by wind erosion of a soft fine-grained rock. Called yardangs, these features are aligned with the prevailing wind direction. This wind direction would have […]

NASAs-MAVEN-Mission-Gives-Unprecedented-View-of-Mars

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 first images of “nightglow” that can be used to show how winds circulate at high altitudes. Additionally, dayside ultraviolet imagery from the spacecraft shows how ozone amounts change over the […]

New Study Predicts Next Global Dust Storm on Mars

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 more predictable — which would be a boon for future astronauts there — if the next one follows a pattern suggested by those in the past. A published prediction, based […]

Evidence for a Potential Microbial Energy Source on Earth and Mars

New research from Yale University shows that rocks formed by the grinding together of other rocks during earthquakes are rich in trapped hydrogen — a finding that suggests similar seismic activity on Mars may produce enough hydrogen to support life. Researchers from Yale, the University of Aberdeen, and Brock University studied rock formations around active […]

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 […]

Giant Tsunamis Battered an Early Martian Ocean

New research from NASA indicates that giant tsunamis played a fundamental role in forming Martian coastal terrain, removing much of the controversy that for decades shrouded the hypothesis that oceans existed early in Mars’ history. “Imagine a huge wall of red water the size of a high-rise building moving towards you at the speed of […]

Hubble Close-up of the Red Planet

Using NASA’s Hubble Space Telescope, astronomers captured this striking image of Mars, when the planet was 50 million miles from Earth. The photo reveals details as small as 20 miles to 30 miles across. On May 30th, Mars will be the closest it has been to Earth in 11 years, at a distance of 46.8 […]

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. […]

New Gravity Map Gives Best View Yet Inside Mars

Scientists have used slight orbital fluctuations to map the gravity field of Mars, providing fresh insights into its crustal thickness, deep interior, and seasonal variations of dry ice at the poles. The new gravity map will also help to put future spacecraft into orbit more precisely, ensuring that the Mars fleet continues to return a […]
