Half of the Atlas payload fairing appears to loom above the Juno spacecraft as work to enclose the spacecraft for launch gets under way.

In the Astrotech payload processing facility near Kennedy Space Center in Florida, half of the Atlas payload fairing appears to loom above the Juno spacecraft as work to enclose the spacecraft for launch gets under way.

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.
