This full view of the giant asteroid Vesta was taken by NASA's Dawn spacecraft, as part of a rotation characterization sequence on July 24, 2011, at a distance of 3,200 miles (5,200 kilometers). A rotation characterization sequence helps the scientists and engineers by giving an initial overview of the character of the surface as Vesta rotated underneath the spacecraft. This view of Vesta shows impact craters of various sizes and troughs parallel to the equator. The resolution of this image is about 500 meters per pixel.

Moffett Field, Calif. - NASA will hold a media teleconference at 11 a.m. PST, Thursday, Feb. 7, to discuss an asteroid 150-feet in diameter that will pass close, but safely, by Earth on Feb. 15. The flyby creates a unique opportunity for researchers to observe and learn more about asteroids.
The teleconference participants are:
-Lindley Johnson, program executive, Near-Earth Object (NEO) Observations Program, NASA Headquarters, Washington
-Timothy Spahr, director, Minor Planet Center, Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass.
-Donald Yeomans, manager, NEO Office, Jet Propulsion Laboratory (JPL), Pasadena, Calif.
