// ORBITAL LOGISTICS AND PROPULSION TERM
Stage Separation
Stage separation is the process of detaching an empty rocket stage from the rest of the rocket during ascent, allowing the remaining stages to continue accelerating with less weight.
TECHNICAL DEFINITION
Stage separation is the critical event in multi-stage rocket flight where an expended booster stage is jettisoned from the remaining vehicle, typically using pyrotechnics or pneumatic systems, to reduce mass and improve overall performance.
BACKGROUND
The Korea Aerospace Research Institute, established in 1989, is the aeronautics and space agency of South Korea. Its main laboratories are located in Daejeon, in the Daedeok Science Town. KARI's vision is to continue building upon indigenous launch capabilities, strengthen national safety and public service, industrialize satellite information and applications technology, explore the Moon, and develop environmentally-friendly and highly-efficient cutting-edge aircraft and core aerospace technology. Current projects include the KSLV-2 launcher. Past projects include the 1999 Arirang-1 satellite. The agency was founded in 1989. Prior to South Korea's entry into the Institute for Advanced Engineering (IAE) in 1992, it focused primarily on aerospace technology. As of May 2024, KARI is an affiliated research institute of the Korea AeroSpace Administration.

USAGE NOTE
Precise timing and reliable mechanisms are paramount for successful stage separation to avoid collisions.
DEVELOPERS
Organizations developing technology related to Stage Separation.
Designs, manufactures, and launches advanced rockets (Falcon 9, Falcon Heavy, Starship) that rely heavily on sophisticated stage separation systems, including 'hot staging' for Starship.
A leading provider of launch services, operating multi-stage rockets like Atlas V, Delta IV Heavy, and the developing Vulcan Centaur, all of which incorporate advanced stage separation technologies.
Responsible for the development and production of the European Ariane launch vehicles (Ariane 5, Ariane 6), which are multi-stage systems with critical stage separation events.
Designs, manufactures, and launches the Electron small-satellite launch vehicle, a two-stage rocket where the first and second stages separate during ascent.
Developing the New Glenn orbital launch vehicle, a two-stage heavy-lift rocket that will employ advanced stage separation mechanisms for its reusable first stage and expendable second stage.
Develops and produces various launch systems and rocket components, including solid rocket motors and complete multi-stage launch vehicles like Antares, which utilize stage separation.
Japan's primary developer and operator of launch vehicles, including the H-IIA, H-IIB, and the new H3 rocket, all of which are multi-stage and require precise stage separation.
