>     New, sharpest-ever views of the planet Mars taken by the Wide 
>Field Planetary Camera-2 (WFPC2) aboard NASA's Hubble Space 
>Telescope on March 10, 1997 (following the successful STS-82 
>Hubble second servicing mission), clearly show clouds, polar caps 
>and other bright and dark markings known to astronomers for more 
>than a century.  The images were taken just before Mars opposition 
>-- when the red planet comes closest to the Earth this year (about 
>60 million miles or 100 million km). Each picture element (pixel) 
>in WFPC2's Planetary Camera's image spans 13 miles (22 km) on the 
>Martian surface.
>     These images show the planet during the transition between 
>spring and summer in the northern hemisphere (summer solstice).  
>The annual north-polar, carbon-dioxide frost (dry ice) cap is 
>rapidly subliming, revealing the much smaller permanent water-ice 
>cap, along with a few nearby detached regions of surface frost.
>     Hubble is being used to monitor dust storm activity to 
>support the Mars Pathfinder and Mars Global Surveyor Orbiter 
>Missions, which are currently en route to Mars.  Hubble's "weather 
>report" from these images, is invaluable for Mars Pathfinder, 
>which is scheduled for a July 4 landing.  These images show no 
>evidence for large-scale dust storm activity, which plagued a 
>previous Mars mission in the early 1970s.
