Launch Notes

One SRB failed to separate, slowing the booster's orbital velocity. Spacecraft eventually reached the correct orbit but with substantially shortened operational life.

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.
