Space Launch Vehicles

KSLV-1 and KSLV-2

KSLV-1 launched on August 25, 2009. It was originally a cluster 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.[6] 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. KSLV-1 was transformed into a two-stage launcher, 33 m high with a maximum diameter of 2.9 m. It has a mass of 140 tons at lift-off. 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 includes the Inertial Navigation System; the power, control, and flight safety systems; plus the nose fairing. KSLV-1 was the most prominent project of the whole South Korean space development program and was successfully launched in late January 2013.[6] South Korea is planning to launch its next rocket KSLV-2 by year 2019. The first stage of its rocket will have 4 clustered engines, each of which will have a 75 metric ton thrust. It was announced that KARI has already developed few prototypes of a 75 metric ton thrust engine.


The Test Launch Vehicle (TLV) is a two stages rocket used to test the performance of the 75-tons and 7-tons thrust rocket engines that will power the KSLV-2. The TLV is 25.8 meters in length, 2.6 meters in diameter, and with a mass of 52.1 tons. The main-stage Kerolox engine is fully gimballed. [7][8]

The first TLV was launched from the Naro Space Center in Goheung, South Jeolla Province. The main objective of the first suborbital flight was for the single-stage rocket's main engine to burn 140 seconds, reaching a 100 km altitude before splashing down in the sea between Jeju Island and Okinawa Island.[10]

The maiden flight was first delayed from October 25, 2018, for two months, due to abnormal readings detected in the rocket propellant pressurization system.[11] The test flight was then rescheduled for November 28, 2018, at 16:00 KST(UTC+9). No payload is to be placed into orbit.[12]

The launch of the first TLV while deemed successful with its main engine burning for 151 seconds in a 10 minute flight,[13] was not broadcast live.[14] After reaching a maximum suborbital altitude of 209 kilometers, the rocket stage hit the ocean 429 kilometers southeast of Jeju.[15]


KSLV-3 was initially designed to launch geostationary satellites of 6 tons, and to enter service in 2023.[16][17] Due to the development of the Small launch vehicle (SSLV), KSLV-III is changed to GEO-SLV, whith a payload of 3t to GEO.[18]


The core stage will powered by four KRE-90 engines of 90 tons thrust, plus four liquid boosters each with a KRE-90 engine. The second stage will be powered by a KRE-90V staged combustion cycle engine.

KRE-010V, the Korean staged combustion cycle engine of 10 tons thrust had a 100 second burn test on December 6th, 2018. It will be used as the upper stage (3rd stage) engine of KSLV-III.[19]

KSLV-4 was expected to carry the 64-tons class space station's modules. KSLV-4 scheduled to enter service in 2028 (updated plan).[20][21][22] Due to the development of the Small launch vehicle (SSLV), KSLV-IV will be no longer be developed.

Small launch vehicle (SSLV)

By 2025 it should be able to put a payload of less than 500kg to LEO.

Solid-fuel launcher

On November 12, 2018, the South Korean government was discussing with its American counterparts, on its plan to develop solid-fuel space vehicles, and comparable to the Japanese Epsilon rocket in performance.[23]

Korean Lunar Exploration Program

In December 2016, KARI signed a lunar exploration technical cooperation with NASA which increased the possibility of exploration success greatly. The Korean Lunar Exploration Program (KLEP) is divided in two phases.[24][25] Phase 1 incorporates the launch and operation of a lunar orbiter called Korea Pathfinder Lunar Orbiter (KPLO), which will be the first lunar probe by South Korea,[26] meant to develop and enhance South Korea's technological capabilities, as well as map natural resources from orbit. Phase 2 will include a lunar obiter, a lunar lander, and a rover[27] to be launched together on a KSLV-II South Korean rocket from the Naro Space Center,[28][24] in 2025.[29][30]

Satellite Navigation

KASS is the Korean model of satellite-based augmented systems (SBAS), a technology that is capable of reducing GPS error to less than 3m. Korea is expected to become the only seventh country in the world to own an SBAS, beginning in July 2020.[31] This technological achievement is a prerequisite for Korea joining the G7.[32]

Korea Multiple- Purpose Satellite-3A

Korea Multiple-Purpose Satellite- 3A (KOMPSAT-3A) was launched on 25 March 2015, on a Dnepr-1 launch vehicle from the Jasny Kombarovsky site in Russia. The purpose of the KOMPSAT-3A is to enable us to take advantage of geographical information systems (GIS) in environmental, agricultural, and oceanographic sciences, and to facilitate natural hazards. The KOMPSAT-3A is equipped with two distinctive sensors, a high-resolution multi-spectral (MS) optical sensor, namely the Advanced Earth Image Sensor System-A (AEISS-A), and the Scanner Infrared Imaging System (SIIS).[33]

Smart Tilt Rotor UAV

In late 2011, KARI unveiled its tiltrotor Unmanned Aerial Vehicle (UAV) that can fly at around 400 km/hr.

Arirang-1 or Arirang I is an unmanned artificial satellite created by the Korea Aerospace Research Institute and launched by a US rocket on December 21, 1999. This was the first satellite built primarily by South Korean engineers, although previous foreign-built satellites had been launched by Korean companies. It carries a surveillance camera able to distinguish objects with a diameter of 6.6 meters. It takes its name from the popular Korean folk song Arirang.

The satellite was launched from Vandenberg Air Force Base in California on a Taurus rocket. It had been built in Daedeok Science Town in Daejeon, South Korea. The parts were shipped in three stages from Korea to California by First Express International, a Korean shipping firm.The Arirang-1 was succeeded by the Arirang-2 in 2006. Additional satellites in the series are planned.

On January 6, 2008, the Korea Aerospace Research Institute reported that they had lost contact with the satellite. It is suspected to have had a malfunction that has affected power generation.


Chollian, (Korean, lit. Thousand Li View) also known as Communication, Ocean and Meteorological Satellite 1 (COMS-1), is a South Korean satellite which was launched in June, 2010. It will be operated by the Korea Aerospace Research Institute, who will use it for communication, oceanography, and meteorological observation.

COMS-1 was constructed by EADS Astrium, and is based on the Eurostar-3000S satellite bus, bringing together ESA-made heritage from Meteosat and lessons learned from Eurostar satellites respectively. It has a mass of 2,460 kilograms (5,420 lb), and carries transponders broadcasting in the D/E and K bands of the NATO-defined spectrum, or the L/S and Ka bands of the IEEE-defined spectrum respectively. Its single solar array is expected to generate a minimum of 2.5 kilowatts of power.COMS-1 was launched by Arianespace using an Ariane 5ECA carrier rocket lifting off from ELA-3 at the Guiana Space Centre in Kourou, French Guiana. The first attempt to launch it occurred on 23 June 2010, however the launch was scrubbed due to a problem with one of the rocket's subsystems. A subsequent attempt on 24 June was also scrubbed, due to a problem with the pressurisation of the rocket's fuel tanks. The launch occurred at 21:41 UTC on 26 June 2010. The Saudi Arabian Arabsat-5A satellite was launched by the same rocket, with a SYLDA adaptor being used to separate the spacecraft. Arabsat-5A was mounted atop the SYLDA, with COMS-1 underneath it.Following launch, COMS-1 separated into a geosynchronous transfer orbit. It will use an apogee motor to raise itself into geosynchronous orbit. Once it reaches this orbit, it will undergo testing before beginning operations at a longitude of 128.2 degrees East. Its mission is scheduled to last seven years, however the satellite has a design life of ten years.

Daedeok Science Town

Daedeok Innopolis, formerly known as Daedeok Science Town, is the research and development district in the Yuseong-gu district in Daejeon, South Korea. Daedeok Innopolis grew out of the research cluster established by President Park Chunghee in 1973 with the opening of the KAIST. Over 20 major research institutes and over 40 corporate research centers make up this science cluster. Over the last few years, a number of IT venture companies have sprung up in this region, which has a high concentration of Ph.Ds in the applied sciences. There are 232 research and educational institutions to be found in Daejeon, many in the Daedeok region, among them the Electronics and Telecommunications Research Institute and the Korea Aerospace Research Institute. The "town" will provide a core for the International Science and Business Belt.

It was expected to be operational for about two years, and was scheduled to be launched between 2005 and 2007.The Satellite Laser Ranging (SLR) instrument was intended to measure the orbit of STSAT-2A, in order to investigate variations in its orbit.It was a followup to STSAT-1, which was launched using a Kosmos-3M rocket on September 27, 2003. Originally a Dual-channel Radiometers for Earth and Atmosphere Monitoring (DREAM) Microwave radiometer was intended as the principal payload of STSAT-2A for an expected launch in 2007. The Laser Retro-reflector Array (LRA) was described as an early expected payload for STSAT-2A which would consist of nine retro-reflectors in a mechanical casing.STSAT-2A has three missions, the indigenous research and development to place a satellite into low orbit, development of indigenous spacecraft, and the ability to develop scientific payloads.STSAT-2A was launched on the maiden flight of the Naro-1 rocket, which lifted off the Naro Space Centre, on the southern coast of South Korea at 08:00 GMT on 25 August 2009. The launch failed to place STSAT-2 into orbit after half of the payload fairing failed to separate. This resulted in the second stage being too heavy to reach orbit, and it fell back to Earth along with the satellite. Further investigation is ongoing. A second satellite, STSAT-2B, was launched on June 10, 2010, but the launch vehicle failed again.


STSAT-2B, or Science and Technology Satellite 2B, was a South Korean satellite which was lost in the failure of the second flight of the Naro-1 carrier rocket. It was to have been operated by the Korea Aerospace Research Institute, and was intended to demonstrate technology for future spacecraft. The satellite had a mass of 100 kilograms (220 lb), and was expected to operate for at least two years.STSAT-2B was originally intended to operate alongside a second spacecraft, STSAT-2A; however STSAT-2A was lost in 2009 after the payload fairing of its carrier rocket failed to separate, leaving the rocket unable to achieve orbit.


STSAT-2C, or Science and Technology Satellite 2C, or Naro Science Satellite(ko:나로과학위성) is a South Korean satellite which was launched in 2013. It is operated by the Korea Aerospace Research Institute, and is intended to demonstrate technology for future spacecraft. The satellite has a mass of 100 kilograms (220 lb), and is expected to operate for less than a year.STSAT-2C was launched at 07:00 UTC on 30 January 2013, on the third flight of the Naro-1 carrier rocket, with a Russian first stage derived from the Angara and a South Korean second stage. Liftoff occurred from the Naro Space Centre, and the rocket successfully deployed the satellite into at 292-by-1,511-kilometre (181 by 939 mi) low Earth orbit inclined at 80.3 degrees. The launch marked the first successful flight of the Naro-1, which had previously failed to launch STSAT-2A in 2009 and STSAT-2B in 2010.
