payloads = See textThe Juno II was an American
rocket used during the late 1950s and early 1960s. It was derived from the Jupiter missile, which was used as the first stage. Sergeant rocket motors were used as upper stages - eleven for the second stage, three for the third stage, and one for the fourth stage - the same configuration as used for the upper stages of the smallerJuno I rocket. On some launches tolow Earth orbit the fourth stage was not flown, allowing the rocket to carry an additional nine kilograms of payload.Launch history
The Juno II was mostly used to launch Pioneer and Explorer spacecraft. Ten were launched, five of which failed to reach orbit, and a sixth reached an incorrect orbit. All launches were conducted from launch complexes 5 and 26B at the
Cape Canaveral Air Force Station .ee also
