Data will help scientists read Curiosity Mars rover samples for signs of life, says UMD coauthor of study published today in Nature. (PRWEB) April 16, 2014 Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. Their study, published April 17 in the journal Nature, shows that the atmospheres of Mars and Earth diverged in important ways very early in the 4.6 billion year...

NASA's Martian Orbiters Find Evidence Of Liquid Water
2014-02-10 13:46:26

[ Watch the Video: MRO Provides New Clues About Water On Mars ] Lee Rannals for redOrbit.com - Your Universe Online NASA’s Mars Reconnaissance Orbiter (MRO) has sent back some evidence that shows liquid water could still exist on the Red Planet. The new images showcase finger-like markings that stream down Martian slopes when temperatures change, as well as show corresponding seasonal changes in iron minerals. Researchers refer to these dark flows as “recurring slope lineae”...

MRO Image Analysis Suggests Possible Salt Water On Mars
2013-12-10 19:42:05

Brett Smith for redOrbit.com – Your Universe Online For decades, scientists have been on a quest to find liquid water on the surface of Mars and new images from the Mars Reconnaissance Orbiter may finally provide that evidence. Newly released images from NASA clearly show dark streaks seasonally advancing down slopes close to the Martian equator, which space agency scientists say could be due to salty water. "The equatorial surface region of Mars has been regarded as dry, free of...

WASHINGTON, Dec. 10, 2013 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter (MRO) has revealed to scientists slender dark markings -- possibly due to salty water - that advance seasonally down slopes surprisingly close to the Martian equator. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) "The equatorial surface region of Mars has been regarded as dry, free of liquid or frozen water, but we may need to rethink that," said Alfred McEwen of the University...

NASA Runs Three Mass Spectrometers In Three Different Places In Space
2013-12-06 17:21:48

Lee Rannals for redOrbit.com – Your Universe Online NASA said that three of its instruments built at the Goddard Space Flight Center were all running three experiments of the same kind at different places in space. The mass spectrometers are designed to take in atmospheric, rock or soil samples and identify particular molecules in them. The instruments help identify gases in atmospheric samples or gases that get released from rock or soil samples as they are processed. “At the...

Martian Atmosphere May Have Experienced Greenhouse Conditions In Ancient Times

[ Watch the Video: Was A Greenhouse Gas Effect Responsible For Ancient Water On Mars? ] redOrbit Staff & Wire Reports - Your Universe Online The combination of molecular hydrogen, carbon dioxide and water could have created a greenhouse effect on Mars nearly four billion years ago, raising temperatures to the point that liquid water could exist, according to research appearing in the latest edition of the journal Nature Geoscience. That could help explain Nanedi Valles,...

Martian Geology More Diverse Than Thought
2013-11-18 13:23:57

Brett Smith for redOrbit.com - Your Universe Online For years, scientists have thought of Mars as being made up of just one kind of rock – a very simplistic planet compared to the diverse geology of Earth. However, a new study in the journal Nature Geoscience suggests there may be granite on Mars and puts forward a theory for how it could have formed there. "We're providing the most compelling evidence to date that Mars has granitic rocks," said study author James Wray, an...

A Peek Into Mars Past

[ Watch The Video: The Evolution Of Mars ] Lee Rannals for redOrbit.com - Your Universe Online NASA released a new video showing how its Mars Atmosphere and Volatile Evolution (MAVEN) mission will be able to look back at the history of the Red Planet. Mars is a cold and barren dessert with red soil and little atmosphere. However, scientists believe that billions of years ago this planet could have not only had a thick atmosphere, but was warm enough to support oceans of liquid water....

TROY, N.Y., Sept. 26, 2013 /PRNewswire-USNewswire/ -- The first scoop of soil analyzed by the analytical suite in the belly of NASA's Curiosity rover reveals that fine materials on the surface of the planet contain several percent water by weight. The results were published today in Science as one article in a five-paper special section on the Curiosity mission. Rensselaer Polytechnic Institute Dean of Science Laurie Leshin is the study's lead author. "One of the most exciting...
