The Greenhouse Gases Observing satellite or GOSAT, also known as lbuki (meaning breath in Japanese) is an Earth Observation Satellite and was launched on January 23, 2009 from Tanegashima Space Center. The GOSAT was developed by Japan Aerospace Exploration agency (JAXA) along with Japan’s Ministry of the Environment and National Institute for Environmental Studies. It is the world’s first satellite to observe global greenhouse gases from space. The impact of greenhouse gases on earth has been more critical in the last few decades. If the situation is unchecked, then the temperature is said to increase by 6 degree Celsius by 2100, and the risk of more extreme climate phenomena such as droughts, heat waves, and floods is expected to increase. The GOSAT’s main objective is to carefully monitor changes in the effects of greenhouse gases without overlooking minute changes so that it can contribute to our future. Its strength of high precision sensor and about 56,000 observation points helps to acquire detailed data on greenhouse gases that have not previously been accurately measured. The IBUKI project is an essential mission for the future living in Earth
