Japan is looking to develop a three-stage next generation rocket by 2020.
That\'s according to a Japanese daily, Asahi Shimbun, which reported on Wednesday that Japan Aerospace Exploration Agency, in collaboration with Mitsubishi Heavy Industries, is planning to develop a three-stage rocket called the H-3.
The envisioned H-3, a three-level parallel connection of rocket engines that were used in the current H-2A and H-2B rockets would serve serve multiple missions heightening Japan\'s capability to send more complex payloads into space.

Mitsubishi Heavy Industries se připravuje na další kolo testování motoru LE-9. O 40% větší tah, než LE-7A, a o 20% míò součástek.
H3 má být o polovinu levnější, než H2A.
