About this audiobook
In 1972, a 260-kilogram spinning probe left Earth faster than any human object before it, crossed the asteroid belt, survived Jupiter's radiation, and became the first machine from Earth to leave the solar system. Its twin followed, past Jupiter and around Saturn, carrying a gold plaque engraved with a man, a woman, and a map of pulsars. This is the complete story of the Pioneer program, the pathfinder missions that opened the outer solar system to exploration.
The early chapters follow the family from its beginnings: the Able-era attempts of the late 1950s, the solar observers of the 1960s that taught engineers to run distant machines, and the trajectory mathematics that made Jupiter reachable. The outer-planet craft follow: the design of ships powered by decaying plutonium, the Atlas-Centaur launches, the crossing of the belt, and the first encounters with Jupiter, told hour by hour, magnetosphere by moon, instrument by instrument.
