Photos: Atlas 5 on the pad at sunset

NASA’s Juno spacecraft, running on solar power more than 500 million miles from the sun, is on final approach for a Fourth of July arrival at Jupiter for a year-and-a-half campaign of exploration.

The United Launch Alliance Atlas 5 rocket was transfered from its assembly building to the pad at Cape Canaveral’s Complex 41 today for Thursday’s launch of the U.S. military’s third SBIRS GEO missile warning satellite.
