The South Korean space agency will launch the second test mission of the Nuri rocket, following the failure of the last launch in October 2021.
If the mission is successful, South Korea will become the seventh nation to have launched a completely created rocket in the home country.
The mission
Nuri is South Korea's second rocket, it was mainly developed by KARI, but around 300 companies also played a role in the development, including Korea Aerospace Industries and Hyundai Heavy Industries.
Flight Test 2 is the second attempt to successfully launch the Nuri rocket after a failed first mission in October 2021. During the first test flight, the rocket successfully flew at the intended altitude of 700 km, but the third stage engine it shut down 46 seconds early, resulting in the cargo not entering orbit.
KARI, thanks to investigations, discovered that the device that anchored the helium tank in the third stage of the rockets was not securely fixed.
Nuri
Nuri is a three-stage rocket designed by the South Korean Space Agency. It is 47.2 m high and 3.5 m wide and can carry 2,600 kg in a 300 km Low Earth Orbit (LEO) and up to 1,500 kg in a orbit of 700 km.
The first stage The first stage has 4 KRE-075 engines which together produce 2,612 kN of thrust. The engines use Jet A-1 propellant and Liquid Oxygen (LOx).
The second stage The second stage has a KRE-075 motor with a larger nozzle than the first motor for greater efficiency and performance in a vacuum environment. This stage also uses Jet A-1 fuel and Liquid Oxygen producing 788kN of thrust.
The third stage The third stage uses a KRE-007 engine that produces 69 kN of thrust and is powered by Jet A-1 fuel and Liquid Oxygen.
