ProtoStar-2 is a geosynchronous communications satellite built by Boeing. It is a BSS-601HP satellite bus. On 15 November 2002, PanAmSat terminated its contract with Boeing Satellite Systems (BSS) for the almost-completed Galaxy-8iR satellite, claiming that Boeing had defaulted on the terms of the contract, and requested US$72 million from Boeing to refund prior advance payments and other costs. The satellite was later converted into the ProtoStar-2 satellite, which was launched in May 2009. Late 2009, it is purchased through auction by SES S.A. for SES World Skies unit for US$180 million. The satellite was renamed SES-7 in May 2010.
