Shown here is a cutaway model of the liquid hydrogen fuel pump for the space shuttle main engine (SSME). During tests in the 1970s, it ran to a pressure of 5,500 pounds per square inch.
Unlike all prior, single-use liquid-propellant rocket engines, the SSME featured reusable interchangeable parts. Pressures in the fuel and other pumps on the SSME pushed the technological state-of-the-art to maximize efficiency during launch and assent.
Donated by NASA-Marshall Spaceflight Center in 1977.
