NASA to Launch Juno Mission to Jupiter Today NASA's Juno
spacecraft awaits launch from inside the payload fairing atop a
United Launch Alliance Atlas V-551 launch vehicle. Juno and its
rocket are at Space Launch Complex 41 on Cape Canaveral Air
Force Station in Florida. NASA's Juno spacecraft is set to
launch today (Aug. 5) on a mission to study the origin and
evolution of the planet Jupiter, the solar system's largest

Force Station in Florida. The forecast calls for a 70 percent
chance of acceptable weather conditions for a Friday launch,

Whisel of the Air Force's 45th Weather Squadron told reporters
