Dust storm hits the Martian north pole
News story originally written on November 1, 1996

The Martian north polar is seen to be besieged by a Texas-sized dust storm. Two Hubble Space Telescope images, taken about a month apart shows this storm sitting at the edge of the north polar cap. It is believed that large temperature differences between the polar icy-regions and warmer dark regions to the south are driving the polar dust storm.
