NASA’s Mars Exploration Rover Opportunity has found bright veins of a mineral, apparently gypsum, deposited by water. Analysis of the vein will help improve understanding of the history of wet environments on Mars.

“This tells a slam-dunk story that water flowed through underground fractures in the rock,” said Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for Opportunity. “This stuff is a fairly pure chemical deposit that formed in place right where we see it. That can’t be said for other gypsum seen on Mars or for other water-related minerals Opportunity has found. It’s not uncommon on Earth, but on Mars, it’s the kind of thing that makes geologists jump out of their chairs.”

The latest findings by Opportunity were presented Wednesday at the American Geophysical Union’s conference in San Francisco.

Opportunity on Verge of New Discovery

September 15, 2011 Leave a comment

Shortly after Labor Day 2011, the Mars rover Opportunity was poised on the rim of the 22,000 meter-wide Endeavour Crater, preparing to sample a novel rock type. Much older than the sedimentary samples the rover’s “tasted” so far, this new sample is flush with the promise of revealing clues to the planet’s environment when running rivers coursed the surface.

What was supposed to have been a 90- to 180-day exploration of two distinct regions of the red planet has turned into a saga that has become one of science’s most compelling and long-lasting adventures (now into its eighth year), enthralling the public and the science communities alike.

The initial work of NASA’s Mars rover Opportunity at its new location on Mars shows surface compositional differences from anything the robot has studied in its first 7.5 years of exploration.

Opportunity arrived three weeks ago at the rim of a 14-mile-wide (22-kilometer-wide) crater named Endeavour. The first rock it examined is flat-topped and about the size of a footstool. It was apparently excavated by an impact that dug a crater the size of a tennis court into the crater’s rim. The rock was informally named “Tisdale 2.”

NASA’s Mars Exploration Rover Opportunity has captured new images of intriguing Martian terrain from a small crater near the rim of the large Endeavour crater. The rover arrived at the 13-mile-diameter (21-kilometer-diameter) Endeavour on Aug. 9, after a journey of almost three years.
