On October 29, the H-2A rocket took off from the Tanegashima Space Center on Tanegashima Island, in Kagoshima Prefecture (Makoto Nagano).
TANEGASHIMA ISLAND, Kagoshima Prefecture – An H-2A rocket took off from the Tanegashima Space Center here on October 29 and was put into orbit by Japan's most accurate satellite for monitoring greenhouse gas emissions.
Greenhouse gases observing the satellite SATellite-2 Ibuki-2 (GOSAT-2) reached their expected orbit about 20 minutes after 13:08. takeoff of the launcher No. 40 H-2A.
The Ibuki-2 was jointly developed by the Japan Aerospace Exploration Agency, the Ministry of Environment and the National Institute of Environmental Studies.
The total cost of the project, including launch, is about 44 billion yen ($ 393 million).
"Ibuki" means "breath" or "puff" in Japanese.
Carbon dioxide (CO2) and methane in the atmosphere absorb light of particular wavelengths. From an altitude of about 600 kilometers, the satellite will calculate the concentrations of CO2 and other substances in the atmosphere by monitoring these wavelengths of reflected light and other factors.
According to JAXA, the satellite can detect 0.5 parts per million of CO2 observations, eight times more accuracy than its predecessor, the first-generation Ibuki, launched in 2009.
Ibuki-2 is also about seven times more accurate for calculating methane concentrations.
Takeshi Hirabayashi, project manager of JAXA's GOSAT-2 mission, said the satellite was so accurate that it could detect a change in concentration in about 200 liters of liquid, or about the volume of the air. a bath, if two drops of eye lotion, or about 1 milliliter, are inserted.
Under the 2015 Paris Agreement, the signatory countries aim to eliminate net greenhouse gas emissions by the second half of the century and limit global warming to "well below" 2 degrees from pre-industrial levels.
Countries are required to report the quantities of greenhouse gases that they have rejected.
The information collected by Ibuki-2 will help these countries to more accurately calculate their emission data, said a Ministry of the Environment official.
