Astronomy Picture of the Day

                         Astronomy Picture of the Day

    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: On Mars [7] dust storms can't actually blow spacecraft over, but
they can blot out the Sun. Over three months [8] ago a planet-wide dust storm
caused a severe lack of sunlight for the Mars rover Opportunity at its
location near the west rim of Endeavor crater. The lack of sunlight sent the
solar-powered Opportunity into hibernation and for over 115 sols controllers
[9]  have not received any communication from the rover. The dust is clearing
[10] as the storm subsides though. On September 20th, when this image was
taken by the Mars Reconnaissance Orbiter's HiRISE camera, about 25 percent of
the sunlight was reaching the surface again. The white box marks a
47-meter-wide (154-foot-wide) area centered on a blip identified as the
silent-for-now Opportunity rover [11] .
