GOSAT was launched along with seven other piggyback probes using the H-IIA, Japan's primary large-scale expendable launch system, at 3:54 am on 23 January 2009 UTC on Tanegashima, a small island in southern Japan, after a two-day delay due to unfavourable weather.78 At approximately 16 minutes after liftoff, the separation of Ibuki from the launch rocket was confirmed.9
According to JAXA, the Ibuki satellite is equipped with a greenhouse gas observation sensor (TANSO-FTS) and a cloud/aerosol sensor (TANSO-CAI) that supplements TANSO-FTS. The greenhouse gas observation sensor of Ibuki observes a wide range of wavelengths (near-infrared region–thermal infrared region) within the infrared band to enhance observation accuracy.10 The satellite uses a spectrometer to measure different elements and compounds based on their response to certain types of light. This technology allows the satellite to measure "the concentration of greenhouse gases in the atmosphere at a super-high resolution."11
The Greenhouse Gases Observing Satellite-2 was launched from Tanegashima Space Center by a H-IIA rocket on October 29, 2018.12
