Go Back

Technicians test the deployment of one of the three massive solar arrays that will power Juno. When Juno arrives at Jupiter in 2016, it will be farther from the sun than any previous solar-powered mission. The choice of solar power for Juno necessitates very large solar arrays 2.65 meters wide by 8.9 meters long. Once in orbit, the three arrays will provide about 450 watts of electricity. The photo was taken on Sept. 13, 2010 at the Materials Test Laboratory at Lockheed Martin Space Systems in Denver.
