According to reports from the Kyodo News Agency, at 9:22 a.m. local time on February 17, the No. 2 H3 rocket, a new-generation carrier rocket developed by Japan, successfully launched from the Uchinoura Space Center on Kagoshima Prefecture’s Shikoku Island. This launch signifies a significant milestone in Japan’s space exploration technology.
The H3 rocket is a new-generation carrier rocket developed by the Japan Aerospace Exploration Agency (JAXA). Compared to previous models, it has a higher cargo capacity and lower launch cost. The rocket is about 60 meters long, has a diameter of about 3.6 meters, a take-off weight of about 320 tons, and a maximum cargo capacity of 16.5 tons. The successful launch of the H3 rocket will provide more convenient and cost-effective space launch services to customers in Japan and internationally.
This launch mission was the second test launch of the H3 rocket, aimed at verifying the rocket’s performance and various technologies. During the launch, the rocket successfully completed critical stages such as engine ignition and separation. In the end, the payload was delivered to the predetermined orbit. The Japan Aerospace Exploration Agency stated that the successful launch of the H3 rocket will lay a solid foundation for future space exploration missions.
In recent years, Japan has achieved many accomplishments in the field of space exploration, including the launch of Galileo satellite navigation systems, components for the International Space Station (ISS), and more. The successful launch of the H3 rocket will further enhance Japan’s position in the international space exploration community and provide more opportunities for scientific research, commercial launches, and other fields in space.
