The crater departure was first attempted Sunday, but the rover's wheels lost traction in the soil.
"NASA's Opportunity tried driving uphill out of its landing-site crater during its 56th sol. (Sunday), but slippage prevented success," mission control reported.
"The rover is healthy, and it later completed a turn to the right and a short drive along the crater's inner slope," NASA said Sunday night.
Controllers sent Opportunity along the crater rim to exit at a different spot. After Monday's successful drive, Opportunity is now sitting 9 meters (about 29.5 feet) outside of the crater.
Also Monday, the rover performed remote sensing observations between naps.
"After completing the drive out of the crater, the navigation camera imaged Opportunity's brand new view of the plains of Meridiani Planum," controllers reported Monday.
"During the martian night, rover planners will awaken Opportunity to take miniature thermal emission spectrometer observations of the ground and the atmosphere."
"Eagle Crater" is approximately 22 meters (72 feet) in diameter. Opportunity has thoroughly examined the exposed bedrock and soil samples within the crater over the past two months, providing scientists with enough data to determine that the site was once drenched in water.
Opportunity's long-range goal is driving across the plains to a much larger crater in the distance.

Another "major scientific finding" from the Mars Exploration Rover Opportunity mission will be announced Tuesday.
The rover is studying the Meridiani Planum region of Mars where it recently discovered evidence rocks at the landing site have been altered by water.
Tuesday's NASA news conference will be held at the agency's headquarters in Washington. The briefing begins at 2 p.m. EST (1900 GMT) with opening remarks from NASA Administrator Sean O'Keefe.
Presenting the discovery will be:
- Dr. Ed Weiler, NASA's Associate Administrator, Office of Space Science
- Prof. Steve Squyres, Cornell University, Ithaca, N.Y., and MER Principal Investigator
- Prof. John Grotzinger, Massachusetts Institute of Technology, Cambridge, Mass, and a MER Co-investigator
- Dr. Dave Rubin, U.S. Geological Survey Sedimentologist at the Pacific Science Center in Santa Cruz, Calif.
- Dr. Jim Garvin, NASA Lead Scientist for Mars and the Moon, Office of Space Science, NASA Headquarters
