Japan launches GOSAT-GW satellite to combat climate change
- The H-2A rocket successfully completed its final flight, marking the end of an era for Japan's space launch capabilities.
- This launch featured the GOSAT-GW satellite, which is designed to monitor greenhouse gases and sea temperatures as part of climate change studies.
- Japan is positioning itself with newer rocket technologies to enhance its competitive edge in the global space market while focusing on addressing climate change.
On June 29, 2025, Japan successfully launched the GOSAT-GW satellite aboard the H-2A rocket from the Tanegashima Space Center. This mission marks the 50th and final flight of the H-2A, which has been a reliable workhorse for Japan’s satellite deployments since its introduction in 2001. The H-2A rocket has had a stellar success record with only one failure in 2003, showcasing Japan's advanced capabilities in space technology. The launch faced some delays due to electrical system malfunctions, but ultimately culminated in a successful deployment of the satellite approximately 16 minutes post-liftoff. The GOSAT-GW is part of Japan's ongoing efforts to study and mitigate climate change by monitoring carbon, methane, and other greenhouse gases in the atmosphere, with data distribution expected to start in about a year after its launch. This satellite is a significant step forward in Japan’s climate monitoring as it joins the array of global observation missions in gathering critical data to help understand the impact of climate change on ecosystems worldwide. Coupled with the impending retirement of the H-2A rocket and the introduction of the newer H3 rocket, this launch signifies a transitional phase in Japan's aerospace endeavors while maintaining a focus on addressing the challenges posed by climate change.
