(WAFF) - The past month has been a busy one for storm chasers on Mars.
NASA reports that a small-scale dust storm had been observed on May 30, but by June 20, it had engulfed the planet.
Activities for the "Opportunity" rover, which depends on solar energy to operate, had to be suspended to preserve its batteries.

NASA says that "Global" dust storms only appear every six to eight years, which is three to four Mars years. Scientists also say that they are still trying to determine how and why these storms form.
