As reported by TASS with reference to the Japanese space agency, we are talking about a proprietary engine that was used in the S-520 meteorological rocket.
The successful launch was carried out from the site of the Uchinoura Space Center in Kagoshima Prefecture.
It is specified that the engine being developed by the Japanese agency generates a shock wave due to the combustion of methane and oxygen.
According to the agency, if the development is successfully completed, the use of this technology will reduce the size of the rocket engine by ten times.
Earlier it was reported that the Japanese billionaire entrepreneur Yusaku Maezawa will travel to the International Space Station on the Soyuz MS-20 spacecraft in December.
