Koreasat 1 (also known as Mugunghwa 1 and Europe*Star B) was a South Korean communications satellite launched by a Delta II rocket from Cape Canaveral Air Force Station, Florida, USA. Owned by KT Corporation.
One of the boosters of the rocket Delta failed to separate from the first stage of the spacecraft, placing it 5,000 km short of its planned GTO apogee. The satellite had to use up 7.5 years worth of its 12-year lifetime fuel supply to make up the deficiency, shortening Koreasat 1's expected life to about 4.5 years. In order to extend its lifetime, it gave up North-South station-keeping operating in "inclined mode." In the end, the satellite managed to function for 10 years.
It was eventually positioned in geosynchronous orbit at 116° E from 1995-2000. In 2000, Koreasat 1 was sold to Europe*Star which renamed it Europe*Star B and operated it at 47.5° E where it was focused on Hungary. The satellite went out of service on December 16, 2005 and was moved to the graveyard orbit. As of March 9, 2007, it was located at 152.88° E drifting at 2.155° W per day.
