The Ministry of Science and ICT announced that the rocket Ariane-5 mounted and developed with Korean technology was launched at 7:18 am from the Guiana Space Center in French Guiana on the same day. About 31 minutes after takeoff at an altitude of 1,630 km, the vehicle was launched, and at 7:55 am, Yatara of Australia made first contact with a satellite station.

The Korea Aerospace Research Institute (KARI) has confirmed that the satellite’s overall condition (including its body) is in good condition and that the Chollian-2B has entered the target movement orbit.

The Chollian-2B, developed by the relevant think tank KARI and the Institute of Electronic Communication since 2011, is used to monitor fine dust and red tide in East Asia including the Korean Peninsula, plankton, sea fog and sea ice.

Satellites that have entered the target transmission orbit will travel through five inter-orbital stages over the next two weeks to their final stop at an altitude of 36,000 km. After entering the final position, it goes through the orbital testing process within a few months.

Chollian-2B will officially provide data on the ocean starting in October and will start forecasting air quality next year.

“Through the successful launch of the Cheonlian-2B, we will actively support the development of advanced satellite functions that deliver to the private sector and improve the economy,” said Vice Minister of Science Chung Byeong-seon.
