Jet Propulsion Lab -- NASA's Mars Global Surveyor, starting its third mission extension this week after seven years of orbiting Mars, is using an innovative technique to capture pictures even sharper than most of the more than 170,000 it has already produced.     One dramatic example from the spacecraft's Mars Orbiter Camera shows wheel tracks of NASA's Mars Exploration Rover Spirit and the rover itself...

NASA's&nbsp;twin&nbsp;Mars rovers&nbsp;Spirit and Opportunity&nbsp;have  yielded volumes of new data about the red planet in the last year - the least of  which involves the planet's history of water. But the rovers have also amazed  their human handlers with their longevity, lasting nearly four times&nbsp;their  initial 90-day mission&nbsp;despite some early glitches that popped up after  landing.

Chile's Atacama Desert is the driest place on Earth. So dry that, in some regions, not even bacteria can survive. That makes it a perfect place to test out ZoÃÂ«, a prototype rover designed to detect life's faintest traces.
