CAPE CANAVERAL, FL - AUGUST 4: In this handout photo provided by NASA, An Atlas V rocket with NASA's Juno spacecraft payload is seen the evening before it's planned launch at Space Launch Complex 41 of the Cape Canaveral Air Force Station on August 4, 2011 in Cape Canaveral, Florida. The Juno spacecraft will make a five-year, 400-million-mile voyage to Jupiter, orbit the planet, investigate its origin and evolution with eight instruments to probe its internal structure and gravity field, measure water and ammonia in its atmosphere, map its powerful magnetic field and observe its intense auroras.
