Peek-A-Boo!

The new Mars Reconnaissance Orbiter, which is just getting ready to begin its main science mission, shows off its capabilities by photographing the Opportunity rover on the rim of Victoria crater. Rover scientists are looking for a route into the half-mile-wide crater. The crater walls contain sheer cliff faces more than 50 feet tall. Layers within these walls contain a geologic record of billions of years of Martian history. [Credit: NASA/JPL/Univ. Arizona]
