Mission

The Koreasat 6A spacecraft, built by Thales Alenia Space, will have 20 transponders for fixed satellite services and six for TV broadcasting to replace the Koreasat 6 launched in 2010. Koreasat 6A will be based on the manufacturer’s Spacebus 4000B2 platform and is expected to weigh about 3.5 metric tons at launch. It will be designed to operate for at least 15 years.
