Provided by Eric Sorensen, Washington State University A Washington State University undergraduate has helped develop a new method for detecting water on Mars. Her findings appear in Nature Communications, one of the most influential general science journals. Kellie Wall, 21, of Port Orchard, Wash., looked for evidence that water influenced crystal formation in basalt, the dark volcanic rock that covers most of eastern Washington and Oregon. She then compared this with volcanic rock...

Martian Dry Ice Gullies Formed By Seasonal CO2 Freezing, Not Water
2014-07-11 09:09:01

Gerard LeBlond for redOrbit.com - Your Universe Online NASA’s Mars Reconnaissance Orbiter (MRO) continually makes high-resolution observations of the surface of Mars. Recent images have revealed that the gullies on the surface are mainly formed by seasonal freezing of carbon dioxide and not liquid water. The report has been published online in the journal Icarus. In 2000, the first reports on these gullies suggested the presence of water on Mars created them by erosion, the same way...

WASHINGTON, July 10, 2014 /PRNewswire-USNewswire/ -- Repeated high-resolution observations made by NASA's Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars' surface are primarily formed by the seasonal freezing of carbon dioxide, not liquid water. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The first reports of formative gullies on Mars in 2000 generated excitement and headlines because they suggested the presence of liquid water on the Red Planet, the...

Curiosity Currently Traveling Through Ancient Glaciers On Mars
2014-06-26 03:13:27

FECYT - Spanish Foundation for Science and Technology 3,500 million years ago the Martian crater Gale, through which the NASA rover Curiosity is currently traversing, was covered with glaciers, mainly over its central mound. Very cold liquid water also flowed through its rivers and lakes on the lower-lying areas, forming landscapes similar to those which can be found in Iceland or Alaska. This is reflected in an analysis of the images taken by the spacecraft orbiting the red planet....

Researchers Discover New Type Of Dust In Mars' Atmosphere
2014-06-23 13:34:22

Brett Smith for redOrbit.com - Your Universe Online Using ultraviolet and infrared imaging techniques, scientists have discovered that the Martian atmosphere contains particulate matter in two distinct sizes, according to a new report published in the journal Icarus. In the study, a team of Russian and French scientists observed the transition of Mars’ northern hemisphere into summer. During this transitional phase, the Sun’s rays poke through the Martian atmosphere and the...

NASA's Mars Reconnaissance Orbiter Captures Images Of Big New Crater
2014-05-22 14:29:15

[ Watch The Video: Mars Weathercam Helps Find Big, New Crater ] NASA's Jet Propulsion Laboratory Researchers have discovered on the Red Planet the largest fresh meteor-impact crater ever firmly documented with before-and-after images. The images were captured by NASA's Mars Reconnaissance Orbiter. The crater spans half the length of a football field and first appeared in March 2012. The impact that created it likely was preceded by an explosion in the Martian sky caused by...

New Study Finds That Lava Carved The Giant Valleys Of Mars
2014-05-13 07:17:31

April Flowers for redOrbit.com - Your Universe Online In 1877, Giovanni Schiaparelli of Italy first described what he called "canali" on the surface of Mars. These straight landforms on the Martian equatorial region form a conspicuous net-like system of deep gorges called the Noctis Labyrinthus, which is clearly visible. Noctis Labyrinthus leads into the even larger Valles Marineris canyon, which is 2500 miles long,  125 miles wide and 4 miles deep. Together, these two systems would span...

Mars Crater May Have Been Wet In The Relatively Recent Past
2014-04-26 05:08:42

April Flowers for redOrbit.com - Your Universe Online Well preserved gullies and debris flow deposits in a crater on the southern hemisphere of Mars are providing new evidence through their geomorphological attributes that they were formed by the action of liquid water in relatively recent geological times, according to a new study from the University of Gothenburg. On Earth, water becomes a single-phase unit and a flow of debris is created when the sediment on a slope is saturated with...

Martian Meteorites Offer Evidence Of Early Atmosphere On Red Planet
2014-04-17 06:47:34

Lawrence LeBlond for redOrbit.com - Your Universe Online Martian meteorites that fell to Earth are revealing secrets of an early atmosphere on Mars that is hidden in the chemical signatures of each ancient rock. Geologists, who collected and studied 40 of these otherworldly rocks, have found an important key to how the atmospheres of Mars and Earth diverged very early in the evolution of the Solar System. The results of this study, published in the journal Nature, will help guide...
