DPS Engine (Old Museum)

After moving from the Rocket Park, the lunar module Descent Propulsion System (DPS) engine spent some time in the main gallery of the "old" part of the museum (next to the lunar module Ascent Propulsion System engine and the lunar module itself) before being moved to the Davidson Center.

Read more about the DPS in my Mechanical Design of the Lunar Module Descent Engine or the Apollo Experience Report: Descent Propulsion System.
