This photo shows the Voyager Proof Test Model undergoing a mechanical preparation and weight center of gravity test at NASA's Jet Propulsion Laboratory, Pasadena, California, on January 12, 1977.

This archival photo shows the Voyager Proof Test Model undergoing a mechanical preparation and weight center of gravity test at NASA's Jet Propulsion Laboratory, Pasadena, California, on January 12, 1977. The stack of three white cylinders seen near center is a stand-in for the spacecraft's power generators (called RTGs). Above that, a silvery canister holds the spacecraft's magnetometer in its stowed configuration.

Voyager is managed for NASA by JPL. JPL is a division of the California Institute of Technology, Pasadena.
