Drawing on their decades of work for nasa and the Jet Propulsion Laboratory (JPL) Drs. Linda and Thomas Spilker give us an inside view of what goes into the unmanned space program, from the origin of a space mission, to how the funds are found to finance it, to how the spacecraft is designed and built, and to the launching and running of such a mission, often designed to last for years and even decades.
