Syracuse 3A & Galaxy 15

Galaxy 15 is an American telecommunications satellite. It was used to provide communication services to North America. In April 2010, Intelsat lost control of the satellite, and it began to drift away from its orbital slot, with the potential to cause disruption to other satellites in its path.

The Syracuse-3 (Systeme de Radio Communications Utilisant un Satellite) series spacecraft are the third-generation military communications satellites for the Délégation Générale pour l'Armement (France's Ministry of Defense's procurement agency).
