Korea Aerospace Research Institute

The Korea Aerospace Research Institute (KARI; ), 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.

Background

KARI began on October 10, 1989, as a national aerospace research institute with the purpose of contributing to sound development of the national economy and enhancement of people's lives through a new exploration, technological advancement, development, and dissemination in the field of aerospace science and technology. It started its research in a temporary building, and had about 30 employees. In 1992, it was designated as a performance quality inspection specialized agency under the Aerospace Industry Development Promotion Act of the Ministry of Commerce, Industry and Energy, and in November 1996, it became an independent foundation called the Korea Aerospace Research Institute.

In 2001, it was renamed to the current Korea Aerospace Research Institute. In 2008, it was incorporated under the Basic Technology Research Council of the Ministry of Education, Science and Technology. In 2014, its affiliation was changed to the National Research Council of Science and Technology. In December 2016, it was selected as a national space development specialized agency.

Organization

The headquarters is located in Daedeok Innopolis in Daejeon, and has various aerospace-related test facilities, including subsonic wind tunnel test facilities, full-body structural test facilities, propulsion test facilities, aircraft control test facilities, and rotary wing test facilities.

* Naro Space Center
The Naro Space Center in Goheung, South Jeolla Province, has major rocket propulsion system test facilities, a launch pad, a tracking station, and launch operation facilities, and a launch pad for private space companies is also planned to be built within the center.

* Goheung Aviation Center
The center is equipped with a 0.7 km long runway, airships, small and unmanned aircraft test facilities, landing gear drop test facilities, and propeller test facilities. From 2003 to 2019, the Goheung Aviation Center conducted performance tests on 168 manned and unmanned aircraft over a period of 16 years, and 76,077 researchers visited the center.

* Tracking station
The Jeju Tracking Station is located in Seogwipo, Jeju Province, 200km away from the Naro Space Center, and is responsible for continuous tracking and information reception of space launch vehicles.

The Palau Tracking Station is equipped with a 7.3m diameter remote data receiving antenna and satellite communication network on a 28,000 m² site. It can receive remote data and images such as real-time flight position, speed, attitude, stage separation, satellite separation signal, pressure, temperature, voltage, and current of launch vehicles or payloads, and can also receive data from launch vehicles that are more than 3,000 km away from the Naro Space Center.

* Deep Sapce Ground Station

The station communicates with a space probe, and is located in Yeoju, Gyeonggi Province. It communicates with the lunar orbiter that will orbit the moon and conduct exploration activities. The antenna reflector sends out radio waves and collects the radio waves sent by the lunar orbiter.

Developments

KARI is also developing Unmanned Aerial Vehicles, high-altitude airships, a next-generation multi-purpose helicopter project, next- generation medium satellite, and a lunar exploration project. In addition, several satellites, including the KOMPSAT (also known as Arirang) Series, the COMS (Communication, Ocean and Meteorological Satellite), and the STSAT (Science and Technology Satellite), are developed, operated, or under development by KARI. On January 30, 2013, they launched a satellite into space from their own soil for the first time.

KARI began in 1989 to develop its own rockets (KSR, Korean Sounding Rocket). It produced the KSR-I and KSR-II, one and two-stage rockets in the early 1990s.

In December 1997 it began development of a LOX/kerosene rocket engine. KARI wished to develop satellite launch capability. A test launch of the KSR-III took place in 2002.

The first-stage unguided rocket KSR-I was produced by KARI in cooperation with research institutes such as industry, academia, and research institutes for the development of rockets. R&D took place for three years from 1990, and the total development cost was 2.85 billion won. Their goal was to develop a solid unguided science tube survey rocket that could observe the ozone layer over the Korean Peninsula.

Earth observation program

KSLV-1 launched on August 25, 2009. It was originally a cluster of indigenous liquid KSR-III rockets with a solid propellant to form a multistage launcher. However, KARI experienced more difficulties than expected in SLV development, because it required much stronger propellant power than KSR-III possessed to launch a satellite into orbit.An, H. (2013). Seeking independence in space: South korea's space program (1958–2010). Quest: History Of Spaceflight, 20(2), 34–51. After several failed attempts, KARI turned to Russia's Khrunichev Design Bureau for assistance in developing a liquid-propellant rocket engine for the KSLV-1 as well as for cooperation in the construction of the launch facility at the Naro Space Center. The first stage of the launcher was derived from the Russian URM-1 (Universal Rocket Module) developed by Khrunichev. The second stage of the launcher was a solid Kick Motor developed by Korea, which included the Inertial Navigation System; the power, control, and flight safety systems; plus the nose fairing.
South Korea launched its next rocket, the KSLV-2 in 2021. The first stage of KSLV-II has 4 clustered engines, each of which has a 75 metric ton thrust. All three stages use indigenously developed rocket engines.

Active Missions: KSLV-1, KSLV-2, Koreasat, ANASIS-II

Korean Positioning System (KPS)

South Korea plans to spend 4 trillion won ($3.56 billion) on building its own Regional Navigation Satellite System (RNSS), named Korean Positioning System (KPS). It plans launching seven new satellites by 2035 — three into geosynchronous orbit and four into inclined geosynchronous orbit. South Korea and the U.S. signed an agreement on "civil global navigation satellite systems cooperation", under which the U.S. will support South Korea developing KPS. The two governments plan to work together to ensure compatibility and enhance interoperability of GPS and KPS for civil purposes.

Lunar and interplanetary missions

The Korean Lunar Exploration Program (KLEP) is divided in two phases.
