An image released on 09/07/98 showing the mysterious "Giant Polygons" of the Martian northern plains. These "Polygons" were first seen by the Viking Orbiters in the 1970's...they appear to be huge cracks in the surface of the Red Planet.

Exploring Mars - Slowly But Surely...
News story originally written on September 11, 1998
The Mars Global Surveyor (MGS)
reached Mars in September 1997. It has circled the planet almost 600 times so far!
There is a problem with one of the antennae on the MGS. Engineers will send it a signal, and then the antenna will pop open. But engineers aren't sure if it will pop open too quickly. This could shake up the spacecraft so that we can't communicate with it any more. Right now, people who work for the MGS project are trying to figure out what to do.
Check out this picture to the left. The MGS took that picture this week...it is of the surface of Mars!
