Mars and the History of Antacids

An anonymous reader writes "NASA's retrospective today on the 1976 Mars Viking mission describes the first probe to orbit another planet, and the first biology experiments based on soil sampling. Program managers maintained a dynamic 'worry list', which included a 1970's computer that opened like a wireframe book. The all-important biology experiments could not be tested prior to launch, then lightning struck the probe components (at Kennedy's Explosive Safe Area Building)."
