Global dust storms on Mars could soon become more predictable—which would be a boon
for future astronauts there—if the next one follows a pattern suggested by those in the past.
A published prediction, based on this pattern, points to Mars experiencing a global dust storm in the next few months. "Mars will reach the midpoint of its
current dust storm season on October 29th of this year. Based on the historical pattern we found, we believe it is very likely that a global dust storm will
begin within a few weeks or months of this date," James Shirley, a planetary scientist at NASA's Jet Propulsion Laboratory, Pasadena, California.
