The Greenhouse gases Observing SATellite, GOSAT (nicknamed "IBUKI"), is the world's first spacecraft dedicated to measuring the concentrations of carbon dioxide and methane from space. The spacecraft was launched successfully on January 23, 2009, and has been operating properly since then. GOSAT is a joint effort promoted by the Japan Aerospace Exploration Agency (JAXA), the National Institute for Environmental Studies (NIES) and the Ministry of the Environment (MOE).
