Rocket Section (n.)

Pronunciation: /ˈrɒkɪt ˈsɛkʃn/

Etymology: Derived from "rocket," from the Italian rocchetto (spindle), referring to a vehicle propelled by engines, and "section," indicating a distinct part of a larger structure. The term is adapted to describe the propulsion and structural base of the Modular Starship, emphasizing its role in launching the spacecraft.

Definition: The detachable propulsion and structural base component of the Modular Starship system, responsible for launching the spacecraft into orbit using powerful engines. It separates from the payload pod and crew nose after reaching low Earth orbit (LEO), re-docks with the crew nose for re-entry, and is designed for full reusability to enhance launch frequency and reduce costs, supporting missions such as lunar flybys and Mars colonization.

Origin: The concept of the Rocket Section was introduced in a 2024 post by KiwiThinker. It emerged as part of the Modular Starship design, gaining prominence with SpaceX's successful Starship test flights in 2024 and 2025, which demonstrated the potential for reusable rocket stages.

Example: "The rocket section powered the Modular Starship into orbit before detaching, ready to be reused for the next mission."

Related terms: Modular Starship, payload pod, crew nose, reusability, low Earth orbit.
