Series 2: Photographs and Artists’ Concepts, 1960-1967 Add to Shelf
The Photographs and Artists’ Concepts series includes real world photographs, and artists’ renderings of SNAP systems (Systems for Nuclear, Auxiliary Power), including SNAP-2, SNAP-8, SNAP-10, and SNAP-10A. Odd-numbered SNAPs were powered by radioisotope thermoelectric generators; even-numbered SNAPs were powered by compact nuclear reactors. Also included in this series is a photograph of Leonard Maki, circa 1960s (Box 2, Folder 10).
Box-Folder 2.6: The SNAP-10A Reactor Space Power System, 1962, 1964-1965 Add to Shelf
Images include an artist's concept of the SNAP-10A System, photographs of the SNAP-10A radiator structure and system mock-up, documentation of the testing, transport and launch of the system, and an artist's concept of the SNAP-10A in orbit (10 images).
Box-Folder 2.7: Underwater Applications of Space Nuclear Power Plants, 1963-1964 Add to Shelf
Conceptual design studies were performed to evaluate the feasibility of using nuclear space power plants for underwater applications. These studies concluded that design changes would be required, but the resulting configurations could be quite attractive for a variety of missions. Images include an artist's concept of an HMBR Reactor, a photograph of a SNAP-8 reactor mockup undergoing shock and vibration testing, and a "Buzz Sawyer" comic strip that incorporates an exact copy of the SNAP-8 reactor in its three-panel narrative of the installation of a nuclear power plant at an underwater laboratory (3 images).
