The sign accompanying the engine. It reads
Apollo Service Module Propulsion System
This is a cutaway of the top part of the Apollo Service Module Propulsion
System (SPS), a liquid-fuel rocket engine used on Apollo spacecraft. The
bottom part, not shown here, consists of a large nozzle. The
SPS engine was mounted at the base of the Apollo service
module, which was attached to the three-astronaut command module. Apollo
astronauts used the SPS to steer their spacecraft toward the Moon, place it in
lunar orbit, and propel it back toward Earth. The SPS engine served
successfully on all Apollo missions, including the Apollo-Soyuz Test Project in 1975.
