How Water Sculpted Mawrth Vallis on Mars

Mawrth Vallis

Sculpted by ancient water flowing on the surface, Mawrth Vallis is one of the most remarkable outflow channels on Mars.

Some Ancient Martian Lakes Came Long After Others

Lakes and snowmelt-fed streams on Mars formed much later than previously thought possible, according to new findings using data primarily from NASA's Mars Reconnaissance Orbiter.

Mars Rover Views Spectacular Layered Rock Formations

The layered geologic past of Mars is revealed in stunning detail in new color images returned by NASA's Curiosity Mars rover, which is currently exploring the "Murray Buttes" region of lower Mount Sharp. The new images arguably rival photos taken in U.S. National Parks.

Martian Cliffs

Grooves On Phobos Can Be Explained by Impacts

Some of the mysterious grooves on the surface of Mars' moon Phobos are the result of debris ejected by impacts eventually falling back onto the surface to form linear chains of craters, according to a new study.

Fossilized Rivers Suggest Mars Was Once Warm and Wet

Extensive systems of fossilised riverbeds have been discovered on an ancient region of the Martian surface, supporting the idea that the now cold and dry Red Planet had a warm and wet climate about 4 billion years ago, according to UCL-led research.

Water Not Found At Location Of Mars' Seasonal Streaks

Seasonal dark streaks on Mars that have become one of the hottest topics in interplanetary research don't hold much water, according to the latest findings from a NASA spacecraft orbiting Mars.

Full-Circle Vista from NASA Mars Rover Curiosity Shows Murray Buttes

Eroded mesas and buttes reminiscent of the U.S. Southwest shape part of the horizon in the latest 360-degree color panorama from NASA's Curiosity Mars rover.

Veins on Mars Formed by Evaporating Lakes

Mineral veins found in Mars's Gale Crater were formed by the evaporation of ancient Martian lakes, a new study has shown.

Today's Gullies On Mars Are Probably Not Formed by Liquid Water

New findings using data from NASA's Mars Reconnaissance Orbiter show that gullies on modern Mars are likely not being formed by flowing liquid water.

Viking Data Lives 40 Years Later

Forty years ago, NASA's Viking mission made history when it became the first mission to successfully land a fully operational spacecraft on Mars.

NASA Viking at 40 Symposium Lectures

This week NASA hosted the Viking Mars Landers 40th anniversary symposium. In 1976 Viking 1 and 2 were the first landers to successfully land on Mars.

An Interesting Unnamed Large Crater On Mars

This striking perspective view from ESA's Mars Express shows an unnamed but eye-catching impact crater on Mars.

Mars 2020 Rover Progresses Toward Launch

After an extensive review process and passing a major development milestone, NASA is ready to proceed with final design and construction of its next Mars rover, currently targeted to launch in the summer of 2020 and arrive on the Red Planet in February 2021.

Continuous Cold Nights On Mars May Stir Up Dust

Some dusty parts of Mars get as cold at night year-round as the planet's poles do in winter, even regions near the equator in summer, according to new NASA findings based on Mars Reconnaissance Orbiter observations.

Recurring Slope Lineae Inside Valles Marineris on Mars

Puzzles persist about possible water at seasonally dark streaks on Martian slopes, according to a new study of thousands of such features in the Red Planet's largest canyon system.

Did A Giant Mars Impact Create Phobos, Deimos - and Another Moon?

International collaboration finds that two small satellites (Phobos and Deimos) orbiting Mars can also be formed by a giant impact like the origin of our Moon. The research is reported in Nature Geoscience, July 2016.
