Nasa finds new evidence of Mars ground-water
Nasa has found new evidence of a wet underground environment on Mars.
In a paper published in the online edition of Nature Geoscience, scientists wrote about the results of their analysis of spectrometer data taken from McLaughlin Crater taken by Nasa’s Mars Reconnaissance Orbiter.
The crater is about 92 kilometres in diameter and 2.25km deep.
The layered rocks of the crater contain carbonate and clay minerals that form in the presence of water. Because McLaughlin lacks large inflow channels, and what small channels it has end at a level that could have been the surface of a lake, it indicates that the lake was fed from ground-water.
"Taken together, the observations in McLaughlin Crater provide the best evidence for carbonate forming within a lake environment instead of being washed into a crater from outside," said Joseph Michalski, lead author of the paper.
"This new report and others are continuing to reveal a more complex Mars than previously appreciated, with at least some areas more likely to reveal signs of ancient life than others," said Mars Reconnaissance Orbiter Project Scientist Rich Zurek of NASA's Jet Propulsion Laboratory, Pasadena, California.
