GOHEUNG, South Korea, Oct. 7 (Yonhap) -- The following is a chronology of major events leading to the fifth launch of South Korea's homegrown space rocket Nuri from Naro Space Center in the country's southern coastal village of Goheung on Wednesday.
June 4, 1993 -- South Korea launches the homegrown one-stage solid propelled science observation rocket, called the Korea Space Rocket-I, after three years of development.
July 9, 1997 -- South Korea launches the homegrown KSR-II two-stage solid propelled science observation rocket. It adopted such advanced technologies as guided control and stage separation compared with the previous version.
March 26, 2001 -- South Korea joins the Missile Technology Control Regime, an informal international association that oversees the proliferation of unmanned delivery systems capable of delivering weapons of mass destruction.
August 2002 -- South Korea and Russia confirm plans to develop the Korea Space Launch Vehicle-I (KSLV-I) rocket, with a launch planned for 2005.
Nov. 18, 2002 -- South Korea launches the liquid-propellant science rocket of the KSR-III. It marked the first time that the country successfully built an independent liquid-fueled rocket, which laid the foundation for the development of small satellite launch vehicles.
2005 -- South Korea and Russia complete work on critical designs for the KSLV-I. The original launch date was postponed until October 2007.
June 11, 2009 -- South Korea opens Naro Space Center. Launch pad certification is completed using KSLV-I GTV. A complete first-stage rocket arrives from Russia by plane.
Aug. 11, 2009 -- After rounds of postponement, South Korea sets a new launch date for Aug. 19, 2009, following consultation with Russia.
Aug. 19, 2009 -- South Korea halts the countdown of the KSLV-I with less than eight minutes to go before blastoff after the automatic launch sequence system detects a problem in a high-pressure tank.
Aug. 25, 2009 -- The KSLV-I is launched and successfully enters orbit. But it failed to deploy a scientific satellite. An independent panel later confirmed a fairing assembly malfunction caused the failure.
March 2010 -- South Korea kicks off the project to develop the KSLV-II space rocket.
June 10, 2010 -- South Korea launches the KSLV-I for the second time, but it exploded 137.19 seconds after liftoff.

Jan. 30, 2013 -- After rounds of rescheduling, South Korea successfully launches the KSLV-I from South Korea's Naro Space Center.
March 2014 -- South Korea successfully conducts the first combustion test of the 7-ton-class liquid engine combustor for the KSLV-II.
June 8, 2016 -- South Korea successfully conducts the 75-ton liquid-fueled engine, which burned for 75 seconds.
March 2018 -- South Korea begins the comprehensive combustion test of the KSLV-II rocket.
Sept. 3, 2018 -- South Korea announces the name of the KSLV-II rocket is Nuri, which means the world in Korean.
Nov. 28, 2018 -- South Korea successfully test-launches the KSLV-Test Launch Vehicle to verify the performance of the liquid engine to be used for the KSLV-II.
Sept. 29, 2021 -- South Korea confirms the date of the Nuri rocket's first launch on Oct. 21 and begins final safety exercises.
Oct. 21, 2021 -- The KSLV-II Nuri rocket lifts off from Naro Space Center. But it ended in partial success, as the rocket failed to put a dummy satellite into orbit despite the successful flight to a target altitude of 700 kilometers. A probe found that the helium tank in the third-stage rocket fell off due to increased buoyancy during the flight and eventually caused the engine to shut off prematurely.
June 15, 2022 -- South Korea postpones the second launch of Nuri, one day ahead of the scheduled liftoff, after detecting irregularities in a sensor in the oxidizer tank.
June 17, 2022 -- South Korea announces a plan to launch Nuri on June 21 after fixing a technical glitch in the oxidizer tank sensor.
June 21, 2022 -- The Nuri rocket lifts off. It succeeded in deploying a dummy and performance verification satellites at a target altitude of 700 kilometers. The satellite made its first communication with the King Sejong Station in Antarctica some 40 minutes after the launch, and the government confirmed Nuri's launch successful. South Korea became the seventh country in the world to develop a space launch vehicle that can carry a more than 1-ton satellite, after Russia, the United States, France, China, Japan and India.
April 11, 2023 -- South Korea sets May 24 as the 3rd launch date of Nuri.
May 24, 2023 -- South Korea calls off the launch of Nuri about three hours before the scheduled liftoff due to a computer glitch in a helium tank facility.
May 25, 2023 -- South Korea's Nuri space rocket lifts off from Naro Space Center and finishes its flight sequence in about 20 minutes after deploying satellites into orbit 550 kilometers above Earth as planned.
It succeeds in deploying the main satellite, NEXTSAT-2, along with seven others into orbit, demonstrating the country's status as one of the seven space powerhouses that have developed a space launch vehicle that can carry a more than 1-ton satellite.
May 27, 2024 -- South Korea launches Korea AeroSpace Administration (KASA) in charge of creating a national strategy in the space field, conducting research and development projects, fostering talent, developing the industry and promoting international cooperation.
July 25, 2025 -- Hanwha Aerospace Co., a major South Korean defense and space company, signs a contract to acquire technologies related to the homegrown Nuri space rocket from the Korea Aerospace Research Institute.
Sept. 30, 2025 -- South Korea sets Nov. 27 as the fourth launch date of Nuri.
Nov. 27, 2025 -- South Korea's Nuri space rocket lifts off from the Naro Space Center.

Aug. 28, 2026 -- South Korea sets Oct. 7 as date for Nuri's fifth launch.
Oct. 5, 2026 -- Nuri's three stages are fully assembled.
Oct. 6, 2026 -- Nuri rocket is moved and erected vertically onto launchpad.
Oct. 7, 2026 -- Nuri rocket lifts off from the Naro Space Center and successfully places 15 satellites into orbit, including five that will form part of South Korea's first domestically launched microsatellite constellation.
