This sequence of radar images of asteroid 2013 ET was obtained on Mar. 10, 2013, by NASA scientists using the 230-foot (70-meter) DSN antenna at Goldstone, CA, when the asteroid was about 693,000 mi (1.1 million km) from Earth.
This image of asteroid Toutatis was generated with data collected using NASA's Deep Space Network antenna at Goldstone, Calif., on Dec. 12 and 13, 2012 and indicates that it is an elongated, irregularly shaped object with ridges and perhaps craters.
Images of asteroid 2007 PA8 have been generated with data collected by NASA's Goldstone Solar System Radar. The images of 2007 PA8 reveal possible craters, boulders, an irregular, asymmetric shape, and very slow rotation.
This radar image of asteroid 2005 YU55 was obtained NASA's Deep Space Network antenna in Goldstone, Calif. on Nov. 7, 2011, when the space rock was at 3.6 lunar distances, which is about 860,000 miles, or 1.38 million kilometers, from Earth.
Night shot of the 70m antenna at Goldstone, California. The parabolic dish is 70m (230 ft.) in diameter. The Goldstone Deep Space Communications Complex, located in the Mojave Desert in California, is one of three complexes which comprise NASA's DSN.
