28 June 2025 year Fr. 16:33 (UTC) From the Tanegasim Space Center, Japan using a launch vehicle «H-IIA 202» the spacecraft was launched «GOSAT-GW».
CA «DARE-GW» (Greenhouse Gases Observing Satellite Greenhouse gases and Water cycle) – This is a new generation of satellites of the Japanese Aerospace Agency (JAXA) To monitor greenhouse gases in the Earth's atmosphere. This is a continuation of gosat missions 2 та GCOM-W.
CA «DARE-GW» has two main tasks:
- Greenhouse Gas Monitoring for Japan's Ministry of the Environment and the National Institute for Environmental Research (PEOPLE).
- Water cycle observations for JAXA.
CA «DARE-GW» has two main devices:
COPPER-3 (Total Anthropogenic and Natural emissions mapping SpectrOmeter-3) — a spectrometer for monitoring greenhouse gas concentrations, such as carbon dioxide and methane, over a large area and with high accuracy. The TANSO-3 spectrometer has a global observation mode, which will allow covering large areas of the Earth's surface without gaps, providing more observation points compared to previous devices, and a detailed observation mode with high spatial resolution, which will make it possible to fix the concentrations of greenhouse gases even more accurately.
AMSR-3 (Advanced Microwave Scanning Radiometer 3) — a radiometer for assessing the quantitative characteristics of water on land, sea surface and in the atmosphere.
The AMSR-3 radiometer will use a larger number of frequency bands to more accurately determine hydrogeophysical conditions, such as rainfall, water vapor, sea ice and ocean surface temperature. The obtained data will help to improve the accuracy of typhoon forecasting, showers and other weather conditions by meteorological services around the world. Also, detailed information on the impact of climate change on the water cycle will allow assessing the consequences of climate change for everyday life and planning appropriate measures.
PH «H-THERE 202» – disposable launch vehicle, which is operated by Mitsubishi Heavy Industries (MHI) for the Japan Aerospace Exploration Agency (JAXA). This liquid-fueled launch vehicle is used to launch a variety of spacecraft. The first flight of the H-IIA rocket took place in 2001 year.
It is reported, that this launch is the last, 50-and flight for H-IIA, which will be completely replaced by the new H3 rocket.
