Galaxy (satellite)
The Galaxy series is a family of communications satellites originally developed and operated by Hughes Communications. It has since merged with PanAmSat and is now owned and operated by Intelsat. As one of the earliest geostationary satellites, Galaxy 1 was launched on June 28, 1983. The latest, Galaxy 19, was launched on September 9, 2008. Subsequent satellites were renamed from satellites formerly known under the Intelsat Americas brands.

- On November 15, 2002, PanAmSat terminated its contract with Boeing Satellite Systems for the Galaxy 8iR satellite that was almost completed, claiming that Boeing did not comply with the terms of the contract, and requested US$ 72 million from Boeing to repay previous advances and other costs. The satellite was later converted to the ProtoStar 2 satellite, which was released in 2009, and was acquired that same year by SES which renamed it to SES-7.
