KRE-075
KRE-075 is a 75-ton thrust liquid rocket engine developed by Korea Aerospace Research Institute. It was used as the first stage engine of the Nuri test launch vehicle in 2018 and as the first and second stage engines of the Nuri in 2021. Development The KRE-075 was developed in 2010 under the leadership of the Korea Aerospace Research Institute. The Hanwha Aerospace participated in the early stages of the project by building the engine, turbo pump, and test equipment. KARI reported at the government space development promotion working committee meeting held on June 29, 2016 that the launch schedule for the test launch vehicle, originally scheduled for the end of 2017, would be postponed by 10 months. There was an issue with the combustion instability of the engine, and at the time, the combustion instability issue had been resolved to some extent. In October 2021, Hanwha Aerospace unveiled this engine to the general public at the Seoul ADEX 2021 exhibition held at Seoul Air ...

Nuri (rocket)
Nuri (; , meaning 'world' in native Korean language, Korean), also known as KSLV-II (Korean Space Launch Vehicle-II), is a Multistage rocket, three-stage launch vehicle, the second one developed by South Korea and the successor to Naro-1 (KSLV-1). It is developed by Korea Aerospace Research Institute (KARI). All three stages use indigenously developed launch vehicle engines, making Nuri the first indigenously developed South Korean orbital launch vehicle (the Naro-1 launch vehicle used a Russian-made first stage). History The South Korean government has striving to develop relatively cheap and reliable rockets competitive enough for the commercial launch market. On 21 October 2021, Nuri made its initial orbital launch attempt at 08:00 UTC and it launched a dummy satellite payload into what was planned to be a Sun-synchronous orbit (SSO). However, despite the payload reaching the targeted apogee (700 km), the third stage shut down about 46 seconds earlier than planned a ...
