Technicians at Astrotech's payload processing facility in Titusville, Fla. guide NASA's Juno spacecraft, as it is lowered by overhead crane, onto the rotation stand for testing.

The solar-powered spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere and investigate the existence of a solid planetary core. Juno is scheduled to launch aboard an Atlas V rocket from Cape Canaveral, Fla. Aug. 5. For more information visit, www.nasa.gov/juno. Photo credit: NASA/Jack Pfaller
