Regarding the launch failure of Japan's small rocket "Epsilon" No. 6, JAXA = Japan Aerospace Exploration Agency has said that it is highly possible that the piping that sends fuel to the device that controls the direction of the rocket was blocked, so it did not work sufficiently. I'll take a look and investigate further.
Regarding the launch failure of Epsilon 6 in October last year, JAXA said that the "second stage gas jet device" that controls the direction of the rocket did not operate sufficiently, so the valve of the pipe through which the fuel, which is the source of the gas, passes. We are continuing to investigate, assuming that either it didn't open enough or the plumbing was blocked.
At an expert meeting held by the Ministry of Education, Culture, Sports, Science and Technology on the 3rd, JAXA conducted verification using a simulated device, etc., and found that the hemispherical rubber film inside the fuel tank connected to the pipe may have blocked the pipe. described as high.
Further verification was done, and the idea of identifying the cause was presented.
JAXA also said that based on the results of the survey so far, it will not affect the launch of the new rocket "H3" scheduled for the 13th of this month.
