Martian dust storm grows global

A storm of tiny dust particles on Mars has prompted NASA's Opportunity rover to suspend science operations. The Martian dust storm has grown in size and is now officially a 'planet-encircling' (or 'global') dust event.

A giant dust storm is raging on Mars

One of the thickest dust storms ever seen on Mars has been spreading since early June. The Opportunity rover - 1 of 2 active rovers on Mars - has suspended science operations.
