Apparently Korea has lost contact with their Arirang 1 satellite which has been in orbit since 1999. Communications were lost one week ago (Dec 30) and they have been unable to reconnect. As is usual with aerospace engineering, the satellite was intended for a short life cycle (3 years) but had apparently been functioning for 8 years until the loss of communication. With a resolution of 6.5 meters, Arirang 1 was superseded in resolution by Arirang 2 which was launched in 2006 with a resolution of 1 meter. The article linked below suggests that Korea will consider the satellite lost if communications are not reconnected soon.
