I think I have crossed one big mountain. "
The development of the H3 rocket is the first new development for a large rocket in Japan in about 30 years, and JAXA and Mitsubishi Heavy Industries are planning to launch the first one in the new fiscal year in a hurry to develop the main engine, which is behind.

On top of that, "I think it's still about going to the 9th station of the whole development. Next, we completed the main engine" LE-9 "as a big mountain, and a big combustion test by incorporating the engine into the system I'm refraining from doing so. I think the summit is still ahead, so I'd like to do my best. "
