Japan’s next-generation rocket: 6.5 ton equipment into geostationary transfer orbit (GTO)
“H3” engine propulsion:
The propulsion power of the engine was increased and the tank was enlarged.
The launch capability of the rocket is 1.3 times higher than that of the conventional rocket.
Launch 6.5 tons or more of equipment such as broadcasting and communication satellites into geostationary transfer orbit (GTO).
Mr. Okada of JAXA:
In “H3”
The satellite storage volume has been significantly increased.
Launched many small satellites at once,
Build a satellite communication network in space,
It can support mega constellation.
In the world, there is an increasing need to carry not only large satellites but also multiple small satellites.
Focus on cost:
“90% of electronic components mounted on rockets” have been commercialized.
Focused on cost to capture global private demand.
Rocket electronic components:
In H3, “90% of electronic parts are replaced for automobiles, etc.”
In engine production, we make full use of 3D printers.
