Juno Marches On
NASA's Juno spacecraft has completed its thermal vacuum chamber testing. The two-week-long test, which concluded on March 13, 2011, is the longest the spacecraft will undergo prior to launch.
In the image, a technician is attaching the lifting equipment in preparation for hoisting the 1,588-kilogram (3,500-pound) spacecraft out of the chamber. Prominent in the photo is one of three large, black, square solar array simulators, which reproduced the thermal properties of Juno's large solar arrays.
NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute at San Antonio. The Juno mission is part of the New Frontiers Program managed at NASA's Marshall Space Flight Center in Huntsville, Ala. Lockheed Martin Space Systems, Denver, is building the spacecraft. The Italian Space Agency in Rome is contributing an infrared spectrometer instrument and a portion of the radio science experiment. JPL is a division of the California Institute of Technology in Pasadena.
