The Juno spacecraft launched aboard an Atlas V rocket from Space Launch
Complex 41 at Cape Canaveral Air Force Station in Florida on Friday,
Aug. 5, 2011. Juno will make a five-year, 400-million-mile voyage to
Jupiter, orbit the planet, investigate its origins 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. Image Credit:
