S. Korea to develop environmental, ocean observation satellite

South Korea plans to develop a next-generation environmental and ocean observation satellite called Cheollian-6, which is set to launch by 2033. The Korea Aerospace Administration (KASA) announced that the proposal has passed a preliminary feasibility review for a state-funded research and development project. The satellite will succeed the current geostationary Cheollian-2B spacecraft, which was launched in 2020.

Cheollian-6 will focus on monitoring environmental and ocean conditions, enabling authorities to detect and track air and marine pollution as well as maritime disasters more efficiently. The satellite will be developed using homegrown technologies, including a hybrid propulsion system, and will be equipped with instruments capable of conducting both environmental and ocean observations from a fixed position relative to the Earth.
