Since late June 2007, Mars has been having a series of regional dust storms, which have obscured most of the planet--and the Mars rovers--with dust. The Mars Reconnaissance Orbiter image from June 22, 2007 (top) shows the first in the series of storms. The July 17, 2007 image (bottom) shows a global "veil of dust" encircling the planet.
