Spacecraft NASA Is Orbiting Massive Asteroid.mp4

ABC News – PASADENA, Calif. July 19, 2011 (AP) NASA’s Dawn spacecraft was captured into orbit around the massive asteroid Vesta after a 1.7 billion-mile journey and is preparing to begin a study of a surface that may date to the earliest era of the solar system, the space agency said Monday. The entry into orbit occurred while the spacecraft’s antenna was pointed away from Earth, so mission controllers had to wait for Dawn to re-establish contact to confirm its success. The capture was estimated to have occurred at 10 pm PDT Friday, when Dawn was 9900 miles from Vesta and 117 million miles from Earth in the main asteroid belt between Mars and Jupiter, according to a statement from NASA’s Jet Propulsion Laboratory. “We are beginning the study of arguably the oldest extant primordial surface in the solar system,” the mission’s principal investigator, Christopher Russell from the University of California, Los Angeles, said in the statement.

Before the Dawn mission, images of Vesta were obtained by ground- and space-based telescopes but did not show much surface detail. Vesta, 330 miles in diameter, is the second-most massive object in the asteroid belt and is believed to be the source
