Japan's H3 Rocket Unit 6 was successfully launched, using three main engines for the first time

The Japanese Aerospace Exploration Agency JAXA launched the H3 rocket No. 6 on the morning of June 12, local time.At 9:53 a.m. local time, the H3 rocket No. 6 was launched from the Tanegashima Space Center in Kagoshima Prefecture and entered the predetermined orbit. The rocket was successfully launched and will gradually deploy six small satellites developed by universities and private companies.

This mission was the first to cancel the solid boosters on both sides and use three domestic main engines instead.

At the same time, this is also Japan's first attempt to domestically produce a large main rocket, with the goal of reducing the launch cost to half of the previous H2A standard - about 5 billion yen (approximately 212 million yuan).

It is reported that the H3 rocket is the successor of the H2A. Its last launch failed in December last year. The second-stage engine combustion of the rocket stopped early during flight, and the satellite carried on the rocket failed to enter the intended orbit.

A few days ago, Japan's Ministry of Education, Culture, Sports, Science and Technology held a meeting and confirmed that the reason for the failure of the H3 rocket No. 8 launch was the poor fit of the base material of the satellite carried by the rocket.

Relevant reports pointed out that the panels that make up the base had poor internal fit during the manufacturing stage, and the resulting gaps expanded during the rocket's flight, ultimately leading to mission failure.
