Twin sections of the Atlas payload fairing are moved closer to the Juno spacecraft during work to enclose the spacecraft for launch.

In the Astrotech payload processing facility near Kennedy Space Center in Florida, twin sections of the Atlas payload fairing are moved closer to the Juno spacecraft during work to enclose the spacecraft for launch.

The fairing will protect the spacecraft from the impact of aerodynamic pressure and heating during ascent and will be jettisoned once the spacecraft is outside the Earth's atmosphere. Juno is scheduled to launch aboard a United Launch Alliance Atlas V rocket from Cape Canaveral, Fla., Aug. 5.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.
