Koreasat 1 [Lockheed Martin]
Koreasat 1 and 2, also known as Mugunghwa 1 and 2, were South Korean communications satellite launched by Delta-7925 rockets from Cape Canaveral. They were based on the Lockheed AS-3000 bus and carried 15 Ku-band transponders to provide TV coverage for South Korea and other Asian countries.
During the launch of Koreasat 1 one of nine solid boosters of the Delta-7925 launch vehicle failed to separate from the rocket, which, therefore, failed to achieve a geostationary orbit. It used up some of the reserved fuel to move it to the geostationary orbit (over the Solomon Islands). This fuel loss entailed a reduced operational lifetime.
Koreasat 1 was sold to Europe*Star as Europe*Star B. In July 2009 Koreasat 2 was sold to Asia Broadcast Satellite as ABS 1A
ABS 1A was retired in 2015 and was moved into a graveyard orbit above the geostationary belt.
