Koreasat 1

Also called Mugunghwa Ir Ho and Europe*Star B

General

Designation	23639 / 95041A
Launch date	5 Aug 1995 at 11:10 UT
Country of origin	South Korea
Mission	Telecommunications
Geostationary orbit	see below
Launch vehicle	Delta 2 #228

The launch experienced a partial failure: a booster rocket to separate. The preliminary reports indicate that explosive lines on the Delta 2 vehicle were damaged by exposure to excessive temperatures, causing one of the solid motors not to separate. The booster separation malfunction was blamed on the heat-related failure of insulation protecting the rocket's booster separation circuits.

This resulted in a wrong orbit delivery. The satellite reached GEO at the end of August on its own and used part of is propellant. Thus its lifetime was reduced to 4.5 years.
