JCSAT-RA previously known as JCSAT-12 is a Japanese geostationary communications satellite which is operated by JSAT Corporation. It was ordered to replace the JCSAT-11 satellite which was lost in a launch failure on a Proton-M/Briz-M rocket in 2007 and is currently used as an on-orbit spare satellite; a role in which it replaced the older JCSAT-R spacecraft providing a reserve for if one of the company’s other satellites fails.
