Back in October 2008, Communication with the satellite was lost. Fortunately for the scientific community, engineers managed to reestablish a link with the satellite a day later. This was considered a warning however, for the engineers, that the satellite is starting to age, the loss in communication was due to an RF (Radio Frequency) switch on the satellite. The current operators of the satellite however, hope that this was just a fluke and say that the satellite will keep running strong...
