An exposed, side view of NASA's Juno spacecraft during its assembly features three of the spacecraft's spherical propellant tanks. Nearby, technicians install components that will aid with the spacecraft's guidance, navigation and control.
This image was taken on June 29, 2010, in the high-bay cleanroom at Lockheed Martin Space Systems in Denver. Here, the spacecraft is mounted on a large rotation fixture which allows the spacecraft to be turned for convenient access for integration and testing of various subsystems.
Juno aims to understand the origin and evolution of Jupiter.
NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute at San Antonio, Texas. 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.
