DUST STORM UPDATE: A severe dust storm on Mars, which has been darkening skies and causing a solar energy crisis for NASA's Mars rovers, refuses to die down. Clouds of dust are now visible in backyard telescopes and Mars is beginning to resemble a orange billiard ball as all of its underlying surface markings are hidden from view. The storm is already a month old and no one knows when it will subside. Visit spaceweather.com for photos and status reports. Interesting.. Its our carbon emmissions no doubt.. causing climate change in the solar system .. Maybe the Martians are making too much gas. Philip.
