GOSAT-GW: Greenhouse Gas Observation Mission by NIES Begins
First observations by the Greenhouse Gases Observing Sensor-3 (TANSO-3) onboard the "IBUKI-GW" (GOSAT-GW)
NIES - The Greenhouse Gases and Water Cycle Observing Satellite "IBUKI GW" (GOSAT-GW), jointly developed by the Ministry of the Environment, the National Institute for Environmental Studies, and the Japan Aerospace Exploration Agency, was launched on June 29, 2025, and is currently undergoing initial functional verification operations. The first observations were conducted by the onboard Greenhouse Gases Observing Sensor-3 (TANSO-3) from July 14 to July 20, and it was confirmed that TANSO-3 was operating normally.

The Japan Aerospace Exploration Agency (JAXA) on Saturday (June 28) conducted its 50th and final launch of the H-2A rocket, taking the GOSAT-GW dual-purpose satellite to space. The mission lifted off from Yoshinobu Launch Complex (LP-1) at the Tenegashima Space Center in Japan at 12:33 p.m. EDT (1633 GMT; 1:33 a.m. June 29, local time in Japan).
New satellite to make detailed survey of greenhouse gas emissions across globe in 3 days
Japan News - To enhance the observation of greenhouse gases from space, the Japanese government will launch a new satellite in June—GOSAT-GW, the third in its series, is capable of performing observations across a plane rather than the current method of observing each point and this makes it possible to survey the Earth’s entire surface within three days.
