Caption:

False colors emphasize the variations in surface brightness on asteroid Annefrank, as seen in an image taken by NASA's Stardust spacecraft during a Nov. 2 flyby of the asteroid.

Stardust flew within about 3,300 kilometers (2,050 miles) of the asteroid as a rehearsal for the spacecraft's encounter with its primary target, comet Wild 2, in January 2004. The variations in surface brightness result from different angles of solar illumination, as well as from intrinsic variations in the surface. The straight edge at the right side of the asteroid's image may be an artifact of processing.

Background Info:

Stardust will bring samples of comet dust back to Earth in 2006 to help answer fundamental questions about the origins of the solar system. Additional information about the mission is available online at http://stardust.jpl.nasa.gov. Lockheed Martin Astronautics, Denver, Colo., built and operates the Stardust spacecraft. Stardust is a part of NASA's Discovery Program of low-cost, highly focused science missions. JPL, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Office of Space Science,Washington, D.C.
