Juno Gets Ready to Shake It
NASA's Juno spacecraft looms above the assembly floor as technicians prepare the Jupiter-bound probe for a round of testing that simulates the vibrations the spacecraft will experience during launch. Juno's dish-shaped high-gain antenna has been installed in preparation for the test, along with the spindly truss that supports adjacent low- and medium-gain antennas. A single solar array has also been installed for the test, and can be seen in stowed configuration on the far side of the spacecraft.
The spacecraft is mounted on a large rotation fixture which allows it to be turned for convenient access for integration and testing of various subsystems. Here, technicians are in the process of rotating Juno into a vertical orientation as they prepare to lift the spacecraft onto a test stand.

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.
