Pioneer 3NASA launches the Pioneer 3 space probe, intended – like its predecessors – to visit the vicinity of the moon. Designed to activate a television camera to get the first look at the moon’s far side, Pioneer 3 never reaches its target, only covering a third of the distance between Earth and the moon before it loops back toward Earth and burns up in the atmosphere a day later. Its near-identical twin, Pioneer 4, will be launched in 1959.
