NASA: Mars Rover Uncovers Minerals

The U.S. space agency, NASA, says its robotic Mars Exploration Rover Opportunity has uncovered mineral deposits on the planet that apparently came from water.

The vein containing the minerals has been named "Homestake," and is about the width of a human thumb.

NASA says the Rover's cameras suggested the mineral in the water is gypsum.

On earth, gypsum is used in making drywall and plaster of Paris.

NASA believes the deposits were likely formed from water flowing out of volcanic rocks.

The agency launched its latest spacecraft to Mars last month.  The Curiosity will be examining the inside of craters when it arrives around the middle of next year. ---VOA News
