Juno prepares for vibration testing

Juno prepares for vibration testing
Juno prepares for vibration testing 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.
