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...

Mars Contains More Clay Minerals Than Expected
2012-12-21 09:13:31

redOrbit Staff & Wire Reports - Your Universe Online A larger portion of the Mars surface is covered by clay minerals - a type of rock that typically forms in places where water is present over an extended period of time - than was previously believed, claims a new study published in the current online edition of the journal Geophysical Research Letters. Eldar Noe Dobrea of the Planetary Science Institute (PSI) and colleagues identified the clay minerals using a spectroscopic...

NASA Spacecraft Monitoring Martian Dust Storm
2012-11-22 07:52:09

NASA/JPL Report A Martian dust storm that NASA's Mars Reconnaissance Orbiter has been tracking since last week has also produced atmospheric changes detectable by rovers on Mars. Using the orbiter's Mars Color Imager, Bruce Cantor of Malin Space Science Systems, San Diego, began observing the storm on Nov. 10, and subsequently reported it to the team operating NASA's Mars Exploration Rover Opportunity. The storm came no closer than about 837 miles (1,347 kilometers) from Opportunity,...

Mars Orbiter Sees 'Dry Ice' Snow On Mars
2012-09-12 04:45:09

Lee Rannals for redOrbit.com - Your Universe Online Although lately it has been snapping images of Curiosity and its landing remnants, NASA's Mars Reconnaissance Orbiter (MRO) data has given scientists the clearest evidence yet of carbon dioxide snowfalls on Mars. Frozen carbon dioxide, or "dry ice," requires temperatures of about negative 193 degrees Fahrenheit, which is considered colder than needed for freezing water. Carbon dioxide snow reminds scientists that although some parts...

Martian Clay Suggests Planet May Have Been Hotter, Less Wet
2012-09-10 08:13:47

Lawrence LeBlond for redOrbit.com - Your Universe Online Evidence that the surface of the Red Planet had a watery past is being challenged by scientists after studies of rock samples from an old atom bomb test site in the Pacific. The new finding suggests that Mars was not as warm and wet as many scientists have predicted. A team of scientists from Caltech have made the theory after their research of rock formations on Mururoa Atoll in French Polynesia. They found these formations...

Curiosity Sends Back New Images From Mars
2012-09-06 13:20:22

Lee Rannals for redOrbit.com - Your Universe Online NASA held a telephone conference with reporters today to give an update about what Curiosity is up to on the Martian surface. The new rover is currently sitting still on the Red Planet, and NASA said it will be moving again towards its target "Glenelg" in about a week. At the future site, there are multiple targets that NASA plans to assess on whether they will be drilling. In an image released by the space agency, there are...
