Japan first showed a new two-stage rocket

The Aerospace Exploration Agency has publicly shown a new two-stage launch vehicle called the H-III for the first time. The rocket is installed on the territory of the Tanegashima cosmodrome in the southwest of Japan. At the moment, work is underway to fill H-III with fuel, which is used as liquid hydrogen, and the oxidizing agent is liquid oxygen.

At the same time, the technicians carry out all the necessary checks. The first launch of the new carrier rocket, presumably, can take place from April 1, 2021, to March 31, 2022. The H-III is Japan’s largest liquid-fueled launch vehicle. It is 63 meters long and 5.2 meters in diameter. It will be able to launch a payload weighing more than 4 tons into a sun-synchronous orbit, and more than 6.5 tons into a geo-transfer orbit.

Thus, the H-III, in comparison with its predecessor, the H-IIA rocket, will be able to launch satellites 1.3 times heavier. At the same time, the production of H-III will be less expensive due to its simplified design, which can reduce the launch cost compared to the H-IIA by 50% — to 45.8 million dollars.
