    Voyager 2's flyby past the planet Neptune in August 1989 is recounted, focusing on its engineering achievements. The failure of its prime receiver only seven months after launch was followed by the failure of a tracking-loop capacitor in its backup receiver. Through clever engineering, that outage proved no more than an inconvenience. Its cameras were meant to work only in certain modes; en route ... View full abstract»
