PARTS SHEET 2 The Propulsion Module
Cassini’s Propulsion Module carries a large mass of propellant mainly to power its rocket engine for deceleration into orbit at
Saturn, a maneuver called Saturn Orbit Insertion (SOI). The module also provides the means for managing the spacecraft’s
attitude, and for small propulsive maneuvers called Trajectory Correction Maneuvers (TCMs). To simplify model construction,
part of the Lower Equipment Module (LEM) is also attached to the Propulsion Module. The rest of the LEM is on Sheet 4.
