The OCO satellite is one of seven scientific spacecraft that Orbital has built, or is in the process of building, for NASA that is based on the company's evolving line of LEOStar satellite platforms. OCO is based on Orbital's LEOStar-2 configuration, on which several other NASA science satellite projects were produced, including the highly successful GALEX, SORCE and AIM missions in low-Earth orbit, as well as the Dawn deep space mission. Later next year, Orbital will launch NASA's Glory satellite, another atmospheric monitoring spacecraft that is based on Orbital's original LEOStar-1, a smaller platform that has hosted three other space missions for various markets including high-resolution commercial imaging, military technology demonstration and space science investigation. In the future, Orbital will introduce the LEOStar-3 bus, which will debut as the platform for the company's Cygnus™ cargo transportation spacecraft during the Commercial Orbital Transportation Services demonstration mission in 2010.
