NASA Finds New Evidence Of Water On Mars

New evidence has NASA wondering where the water came from.  New information shows that the ground where Spirit, the Mars Exploration Rover, was stuck last year indicates the presence of water.  Officials believe the water reached the subsurface as snow melted and continued to accumulate over a period of time.

Current information has led scientists to propose the water may have come from melted snow or frost on the surface of Mars, potentially during a cyclical climate change.  The evidence of water on the planet was found under stratified layers of soil.  While scientists detected many insoluble minerals near the surface of the planet, a number of more soluble minerals were found under the surface.  Scientists believe the minerals were likely deposited in the lower soil levels by traveling in water.

The findings can be found in a report published in the Journal of Geophysical Research by Ray Arvidson, the principle investigator for the Mars rovers.  Data for the report comes from late 2007 thru March of this year when the rover stopped communicating.  The findings are part of “bonus” explorations the rovers were able to complete when the mission officially ended in April 2004.

The rover is currently in a hibernation mode and may or may not wake up.  If the machine does wake up, scientists believe it will take place during the spring, which is nearly here on the rover’s part of Mars.  Should the rover be usable, scientists will continue to explore the planet until it shuts down for good.
