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: NASA/Bill Ingalls
