Environment Scouting Satellite “Chollian 2B” successfully made its launch on the Ariane 5 ECA rocket from the space center in Kourou, French Guiana, as scheduled, divulged by the Korea Aerospace Research Institute.


Starting October, Chollian 2B will begin its real-time data transmission on marine conditions, in which the information gathered would help the nation combat potential maritime issues like oil spills, or those red and green tides, among others.

By the next year of January, with upgraded equipment called geostationary environmental monitoring spectrometer, Chollian 2B will also begin observing air conditions specifically towards ozone, sulfur dioxide, formaldehyde, among other 20 air pollutants across the Asian regions.

“Chollian 2B is the world’s first geostationary satellite that provides information on air pollutants, including fine dusts. The satellite will help us to counter air pollutant issues by tracking where pollutants have originated from and where they travel to,” said Chung Byung-sun, the first vice minister of the Ministry of Science and ICT.

“The geostationary satellite will conduct 24-hour monitoring of air pollutants, offering us much more detailed and accurate information compared to the past,” shared the National Institute of Environmental Research President Chang Yoon-seok.

Furthermore, atmospheric data collected will be used for research materials and can also be shared with neighboring countries, according to the ICT Ministry.

Followed by the successful launch, the government also had another geostationary communication satellite planned out which is expected to launch in 2027.
