>NEW HUBBLE IMAGES SHOW DUST STORMS AT MARS NORTH POLE 
>
>       Two Hubble Space Telescope images of Mars, taken 
>about a month apart on September 18 and October 15, 1996, 
>reveal a Texas-sized dust storm churning near the edge of 
>the Martian north polar cap.  The polar storm is probably a 
>consequence of large temperature differences between the 
>polar ice and the dark regions to the south, which are 
>heated by the springtime Sun.
>
>       Mars is famous for large, planet-wide dust storms.  
>Smaller storms resembling the one seen here were observed in 
>other regions by Viking orbiters in the late 1970s.  
>However, this is the first time that such an event has been 
>caught near the receding north polar cap.  This kind of 
>advanced planetary "weather report" will be invaluable for 
>aiding preparation for the landing of NASA's Pathfinder 
>spacecraft in July 1997 and the arrival of Mars Global 
>Surveyor (MGS) orbiter in September 1997.  The MGS mission 
>is scheduled for launch on November 6, and the Mars 
>Pathfinder is scheduled for launch December 2.
