The Greenhouse Gases Observing Satellite-2 (GOSAT-2), also known as Ibuki-2 (Japanese: いぶき2号, Hepburn: Ibuki nigō), is an Earth observation satellite dedicated to greenhouse gas monitoring. It is a successor of Greenhouse Gases Observing Satellite (GOSAT). The GOSAT-2 was developed as a joint project of the Japan Aerospace Exploration Agency (JAXA), Ministry of the Environment, and the National Institute for Environmental Studies (NIES). It was launched on 29 October 2018 from the Tanegashima Space Center aboard the H-IIA rocket.[citation needed]
