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.
Under the unflinching summer sun, workers at NASA's Deep Space Network complex in Goldstone, Calif., use a crane to lift a runner segment that is part of major surgery on a giant, 70-meter-wide antenna.
The giant, 70-meter-wide antenna at NASA's Deep Space Network complex in Goldstone, Calif., tracks a spacecraft on Nov. 17, 2009. This antenna, officially known as Deep Space Station 14, is also nicknamed the 'Mars antenna.'
Workers at NASA's Deep Space Network complex in Goldstone, Calif., pour in a new epoxy grout as the giant "Mars antenna" undergoes major surgery. The grout is part of the hydrostatic bearing assembly, which enables the antenna to rotate horizontally.
An engineer at NASA's Jet Propulsion Laboratory in Pasadena, Calif., checks the evenness of sole plates installed on the giant "Mars antenna" at NASA's Deep Space Network communications site in Goldstone, Calif.
As the sun sets on July 8, 2010, workers prepare to pour new epoxy grout for the hydrostatic bearing assembly of the giant "Mars antenna" at NASA's Deep Space Network communications site in Goldstone, Calif.
