Mars Rover Moves, NASA Plots Course
Wednesday, January 14, 2004
PASADENA, Calif. — NASA's (search) Spirit rover has rolled for the first time since reaching Mars (search), backing up 10 inches atop its platform as it began to reposition itself in preparation for exploring the Red Planet's (search) surface later this week./snip/
Spirit's first major destination is an unnamed crater an estimated 825 feet away. The asteroid or meteor that punched out the crater could have exposed ancient rocks that may reveal to Spirit and its half-dozen instruments the evidence that the robot was sent to find, Squyres said.
After that, NASA may dispatch Spirit on a rambling journey toward a cluster of hills to the southeast. But the hills are nearly two miles away, or about five times farther than Spirit is expected to be able to travel.

Spirit probably will conk out before reaching the hills, however. Martian temperatures of minus 100 degrees Fahrenheit and colder wreak havoc with spacecraft electronics and other components, stressing and, ultimately, breaking them. The last rover NASA sent to Mars, 1997's Sojourner, lasted nearly 90 days before it succumbed to the cold.
