Authors Henry C. Dethloff and Ronald A. Schorn tell the story of how a rare planetary alignment allowed NASA to mount one of the most spectacular missions of exploration in human history - the voyager probes to the outer planets.
From the estate, and personal collection of Dr. Edward Stone, former director of the NASA Jet Propulsion Laboratory (JPL) from 1991 to 2001. He was the project scientist of the Voyager program, which sent two spacecraft to the outer Solar System's giant planets and became the first spacecraft to enter interstellar space.
