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.'
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.
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.

Work began on March 11, 2010 to replace a set of elevation bearings on the giant 'Mars antenna' at NASA's Deep Space Network complex in Goldstone, Calif.
Workers in Goldstone, Calif., guide a new runner segment into the hydrostatic bearing assembly of a giant, 70-meter-wide (230-foot-wide) antenna that is a critical part of NASA's Deep Space Network.
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.
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.
Workers at NASA's Deep Space Network's Goldstone Deep Space Communications Complex put into place a set of support legs to help hold up a portion of the giant 'Mars antenna' on May 4, 2010.
