TOKYO (JAXA PR) — The Japan Aerospace Exploration Agency (JAXA) has been pressing forward with the development of the H3 Launch Vehicle. In the process, a technical problem was identified regarding the LE-9 first-stage engine, which is a new engine now under development.

In order to address the problem in an appropriate manner, JAXA has decided to postpone the launch of the first test flight from the Japanese fiscal year (JFY) 2020 to JFY 2021 and that of the second test flight from JFY 2021 to JFY 2022. [Editor’s Note: The 2020 fiscal year ends on March 31.]

JAXA will deal with the LE-9 engine-related problem in an appropriate manner and make an all-out effort for the successful launch of the H3 as a new Japan’s mainstay rocket.
