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...

Opportunity Rover Finds Martian Rock With Unique Composition
2013-05-18 04:32:57

redOrbit Staff & Wire Reports - Your Universe Online NASA´s Mars Exploration Rover Opportunity has discovered a pale rock that has a higher composition of aluminum and silica and a lower concentration of calcium and iron than any other rock it has examined during its time on Mars, the US space agency announced on Friday. The fractured rock, which is known as “Esperance,” is located in the “Cape York” region of Mars and was said to have been...

[ Watch the Video: Mars Dry Ice and Dunes ] April Flowers for redOrbit.com - Your Universe Online A new study, led by the Planetary Science Institute's Senior Scientists Candice Hansen, shows that the spring thaw on Mars leads to a variety of geologic changes on the planet's surface. Frozen carbon dioxide, also known as dry ice, is deposited on the dunes surrounding the north pole's permanent water ice polar cap. In the spring, as it begins to sublimate, or change directly from a...

Mars Crater May Have Been Home To Groundwater-fed Lake
2013-01-21 04:10:25

redOrbit Staff & Wire Reports - Your Universe Online NASA´s Mars Reconnaissance Orbiter (MRO) has discovered evidence of a wet underground environment which suggests the planet could have once been home to a groundwater-fed lake, the US space agency announced on Sunday. The new data is the result of spectrometer data collected by the probe of the floor of McLaughlin Crater, which is 57 miles in diameter and 1.4 miles deep. The depth of the crater apparently allowed water to...

Researchers using NASA's Mars Reconnaissance Orbiter have found possible flowing water on Mars. A team using the HiRISE camera aboard the Mars orbiter have tracked seasonal changes to determine that finger-like features appear and extend down some Martian slopes during the warmest months of the Mars year. The features fade during the winter, and return during the next spring.  Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in...
