Shifting Dunes and Squiggly Lines on Mars

The Mars Global Surveyor spacecraft, which has been orbiting the Red Planet since 1997, was relegated to the media shadows early this year when it’s new sister craft, Mars Odyssey, began returning pictures and found intriguing evidence for water ice near the surface of Mars. However, Surveyor, also called MGS, is alive and well and still producing remarkable photographs with its onboard Mars Orbiter Camera. Most of the pictures do not individually provide for important findings, but many are interesting nonetheless.
