Sea Launch was a multinational spacecraft launch service provider that utilized a unique mobile maritime launch platform, the *Odyssey*, for equatorial launches. Employing specialized Zenit-3SL rockets, it aimed to provide reliable and affordable access to geostationary orbit for commercial satellites. Key partners included Boeing, RSC Energia, and Yuzhmash, with customers such as EchoStar, DirecTV, and Intelsat. The company ceased operations in 2014 and was later acquired by Russia's S7 Group.
