The "Rovers on Mars" screensaver features 42 high-quality pictures from the Mars Exploration Rovers. It comes with a free "MER Spacecraft 3D" screensaver upon purchase.
Moreover, there's a second rover, MER-B (Opportunity), which landed on January 24, 2004 in Meridiani Planum. The two rovers have been instrumental in revealing geologic formations never seen before, and they have confirmed that Mars had at least one salty sea in the distant past. It's fascinating how they've been going strong, and mission funding has been extended to September 2006, and perhaps longer.
With the "Rovers on Mars" screensaver, you also get the "MER Spacecraft 3D" screensaver for free. This feature allows you to see the cruise-configuration spacecraft that delivered the rovers to the surface of Mars. It is an absolute delight watching the craft position itself for entry to the Martian atmosphere.
In conclusion, if you're fascinated with Mars exploration and want to relive the experience at home or office, "Rovers on Mars" screensaver is an excellent choice. Not only do you get to see breathtaking pictures, but you also get the "MER Spacecraft 3D" screensaver for free. It's worth it!
