Global Observing Satellite for Greenhouse gases and Water cycle (GOSAT-GW), also called Ibuki GW, is a Japanese Earth observation satellite for observing the global water cycle and greenhouse gas monitoring. It is a successor to the GCOM-W and the GOSAT-2 satellites. GOSAT-GW was jointly developed by the Japan Aerospace Exploration Agency (JAXA), Ministry of the Environment, and the National Institute for Environmental Studies (NIES). GOSAT-GW was launched on 28 June 2025, on the last launch of JAXA’s workhorse H-IIA rocket. [2]
