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

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...

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
2013-11-25 03:46:52

[ 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....

Curiosity Gets The First 'Scoop' On Martian Water Discovery
2013-09-26 14:50:20

[ Watch the Video: Curiosity Rover Instrument Finds Watery Evidence ] Lee Rannals for redOrbit.com - Your Universe Online Curiosity has added another huge discovery to its repertoire, as scientists report finding water in the NASA rover's first soil scoop taken on the Martian surface. The latest finding, published in the journal Science, shows that the rover's first scoop of soil contained fine materials that were several percent water by weight. "One of the most exciting results...
