• Developed By: Japan Aerospace Exploration Agency (JAXA)

• In collaboration with Mitsubishi Heavy Industries (MHI), which handled launch operations.

• Launched Through:

• H-2A rocket, a liquid-fuel launcher with solid-fuel boosters, from the Tanegashima Space Centre.

• Objectives:

• Monitor Greenhouse Gases: Collect data on carbon dioxide, methane, and other climate-impacting gases. Study Global Water Cycles: Measure Sea surface temperature, cloud cover, and precipitation trends. Support Climate Policy: Provide accurate, high-resolution data to global stakeholders including NOAA (USA).
