A dusty shade of Mars

A dusty shade of Mars
A dusty shade of Mars Two images, taken by the Mars Orbiter Camera (MOC) onboard the now decommissioned Mars Global Surveyor orbiter in 2001, show the dramatic change in the planet's appearance when haze raised by a planet-circling dust event grew from the south and became globally distributed. The images were taken about a month apart. This was the first planet-encircling dust event that NASA’s Mars Exploration Program witnessed in 20 years of constant observation. There was another one in 2007, which Opportunity survived. Now this storm that the rover is trying to ride out, looks to be only the third such massive storm during the last two decades.
