Old Spirit Data Points To New Evidence Of Ancient Water In Mars Crater
2014-04-10 07:36:05

Lawrence LeBlond for redOrbit.com - Your Universe Online The hunt for a confirmed source of ancient water on the Red Planet may be over (or just beginning), at least for one group of scientists. Mars scientists looking at old data provided by NASA’s Spirit, one of the two rovers that landed on the Martian landscape a decade ago, have found evidence of ancient water inside the crater in which the rover landed. Spirit landed in the 100-mile-wide Gusev Crater in 2004 and scientists have...

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...

Rocks on Mars dug from far underground by crater-blasting impacts are providing glimpses of one possible way Mars' atmosphere has become much less dense than it used to be. At several places where cratering has exposed material from depths of about 5 kilometers (3 miles) or more beneath the surface, observations by a mineral-mapping instrument on NASA's Mars Reconnaissance Orbiter indicate carbonate minerals. These are not the first detections of carbonates on Mars. However, compared to...

PASADENA, Calif., June 3 /PRNewswire-USNewswire/ -- Rocks examined by NASA's Spirit Mars Rover hold evidence of a wet, non-acidic ancient environment that may have been favorable for life. Confirming this mineral clue took four years of analysis by several scientists. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) An outcrop that Spirit examined in late 2005 revealed high concentrations of carbonate, which originates in wet, near-neutral conditions, but dissolves in...

Confirming this mineral clue took four years of analysis by several scientists. An outcrop that Spirit examined in late 2005 revealed high concentrations of carbonate, which originates in wet, near-neutral conditions, but dissolves in acid. The ancient water indicated by this find was not acidic. NASA's rovers have found other evidence of formerly wet...

U.S. space agency scientists say they've discovered a mineral on the surface of Mars that indicates the Red Planet supported water many billions of years ago. Researchers using a powerful instrument aboard the National Aeronautics and Space Administration's Mars Reconnaissance Orbiter found the long sought-after mineral -- carbonate -- that indicates Mars had neutral to alkaline water when the minerals formed more than 3.6 billion years ago. Carbonates, which on Earth include limestone and...

The classic technique for assessing the history of a rocky planet's geology is to count craters. On average, areas with longer exposure to space have had more impacts, and therefore more craters. By counting craters, scientists have broken the geologic history of Mars into three eras: Noachian (warm and wet), Hesperian (volcanic), and the present-day Amazonian (cold and dry). Following Earthly practice, each era is named for the location where the characteristic terrain was first identified....

ESA -- Substantial quantities of liquid water must have been stably present in the early history of Mars. The findings of OMEGA, on board ESA's Mars Express, have implications on the climatic history of the planet and the question of its 'habitability' at some point in its history. These conclusions were drawn thanks to data on Martian surface minerals obtained by OMEGA (Observatoire pour la Mineralogy, l'Eau, les Glaces et l'Activit©), the visible and infrared mapping spectrometer on...
