English: This set of images from NASA's Mars Reconnaissance Orbiter (MRO) shows a fierce, giant dust storm is kicking up on Mars, with rovers on the surface indicated as icons. The spread of the storm can be seen in the salmon-colored overlay. These images from MRO's Mars Color Imager start from May 31, when the dust event was first detected, and go through June 11, 2018.

MRO creates global maps of Mars but roll maneuvers for targeted observations produce gaps in the coverage, which appear as black gores in the maps. On some days there are data drops where partial or full orbits of coverage are missing. Green and purple observed in the south polar region indicate saturated pixels. Latitude is indicated along the vertical axis. Longitude is indicated along the horizontal axis.

Malin Space Science Systems, San Diego, provided and operates MARCI. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, built the spacecraft.
