Succeeded in launching “IBUKI No. 2” that accurately observes greenhouse gases

The H2A rocket No. 40 carrying the satellite “IBUKI No. 2” that observes greenhouse gases was launched from the Tanegashima Space Center in Kagoshima Prefecture at 1:08 pm on the 29th. According to the Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries, which were responsible for the launch, the satellite was put into the planned orbit and the launch was successful.

“IBUKI No. 2” was jointly developed by JAXA, the Ministry of the Environment, and the National Institute for Environmental Studies. When the solar panel is opened, the maximum width is about 16.5 meters and the weight is 1.8 tons. It is the successor satellite of “IBUKI” launched in January 2009 and is equipped with an observation sensor with higher performance than “IBUKI”. In addition to carbon dioxide (CO2) and methane, carbon monoxide, which also has a greenhouse effect, will be newly observed. It is said that it boasts eight times the accuracy of “IBUKI” in CO2 measurement. In addition to observing greenhouse gases throughout the earth while orbiting at an altitude of 613 km, the concentration of particulate matter “PM2.5”, which has been pointed out to have an adverse effect on health, is also estimated to monitor the status of arrival in Japan. do.

The Paris Agreement, an international framework for preventing global warming, aims to limit temperature rise to less than 2 degrees Celsius, preferably 1.5 degrees Celsius, compared to before the Industrial Revolution. Each country is obliged to report greenhouse gas emissions, but IBUKI No. 2 is expected to contribute to international efforts to reduce emissions because it can accurately observe emissions.

According to the International Energy Agency (IEA), CO2 emissions from global energy consumption in 2017 increased by 1.4% from the previous year to reach 32.5 billion tons. It was flat for 14 to 16 years, but turned to an increase. The IEA states that the current efforts are insufficient to achieve the goals of the Paris Agreement, an international framework for preventing global warming.

In addition to “IBUKI No. 2”, the H2A rocket No. 40 was developed by Tohoku University, Osaka Institute of Technology, Kyushu Institute of Technology, Shizuoka University, Aichi University of Technology, and the Arab Emirates (UAE) for the first time. The land observation satellite was also installed.
