Mission
Ranger 5 extended the run of misfortune to five. Launched on 18 October 1962, it lost electrical power a few hours into the flight — a short circuit left it running down its batteries with no way to recharge. Dead within hours, it coasted past the Moon, missing by about 725 kilometres, and drifted off into solar orbit. Five Ranger flights had now flown and not one had returned a usable picture of the Moon. The programme was redesigned and its management overhauled before the next attempt — the pressure to finally deliver was immense.
