Exciting News from the Red Planet!
News story originally written on December 19, 2000

The Mars Global Surveyor (MGS) is in orbit around Mars. I took some really important pictures this month!

Pictures like the one to the left tell scientists that there may have been lakes and seas on Mars a long, long time ago. Right now, we think of Mars as a bunch of dry rocks. But the pictures that MGS took show that Mars may have been wetter and drier 3.5 billion years ago. That means that in the past, Mars may have been more like the Earth is now.

Use your imagination to picture Mars with lakes and seas on it!
