Atomic Power in Space: A History, Vol. 2

The U.S. Department of Energy (DOE) published its first volume on the history of nuclear power in space in 1987. The book, written by Richard Engler, documents the development and use of radioisotope thermoelectric generators (RTGs) and radioisotope heater units (RHUs) in space from the first RTG launch in June 1961 to the mid-1980s. A sequel, picking up where the first volume ended, is currently under development.

The new book will document RTG and RHU use in space from the mid-1980s to the completion of the Mars Science Lab mission, with the landing of the RTG-powered spacecraft planned for August 2012. In addition, Vol. 2 will examine other types of nuclear power technologies, such as a new radioisotope power system being developed to use highly efficient Stirling engines, as well as nuclear reactors for onboard power, surface applications and nuclear propulsion.

Atomic Power in Space: A History, Vol. 2 is being written for both scientific and general audiences. By serving as an historical reference, it will help guide nuclear and space scientists in future thinking and mission planning. Also, it will enhance public understanding of the role that nuclear technologies have played in enabling important space missions that are reshaping our understanding of the universe, as well as the role that these power sources can play in the future.

Details on obtaining the new and earlier publications will be posted on this website when they are available.
