Question

Newly released images NASA's Mars Global Surveyor

Answer 1

Newly released images from NASA's Mars Global Surveyor show that the red planet is a different place today than it was two years ago when the spacecraft arrived -- a world constantly reshaped by forces of nature including shifting sand dunes, monster dust devils, wind storms, frosts and polar ice caps that grow and retreat with the seasons.

"Mars is a cold, dry desert, but our camera has shown it is far from being a stagnant place," said Dr. Michael Malin, principal investigator for the Mars Global Surveyor camera at Malin Space Science Systems, San Diego, CA. "Over the past few months, we have captured a unique record of seasonal and meteorological events, which demonstrates that Mars is active and dynamic today."
