About Japanese rocket technology. JAXA is an organization called NASA in Japan. A rocket has been launched around this JAXA. There is a thing called H2A rocket.
Production is being carried out by Mitsubishi Heavy Industries, and the 44th launch was carried out on October 26, and the satellite called "Michibiki" was successfully put into orbit.
44 launches and 43 successful launches. The success rate has reached 95%, and the level has risen to the international level.
"Michibiki" is a GPS satellite made in Japan. By combining the data of the American GPS satellite and "Michibiki", the accuracy will be much higher, and the error can be improved to 6 cm by using a dedicated receiver.
The H2A rocket can launch satellites of 4 to 6 tons, and can launch multiple satellites at the same time. Unit 40 was launched on October 29, 2018, and DIWATA-2B, a disaster monitoring and natural resource observation satellite for the Philippines of Tohoku University, has also been successfully launched.
The H2B rocket is launching a spacecraft called "Kounotori". The "Kounotori" is carrying the necessary supplies to the space station ISS. Launched 9 times in the past, all successful. The operation of the H2B rocket has ended.
The Epsilon rocket is a rocket developed to launch a relatively small artificial satellite, and has been launched four times in the past, and all four have been successful. Because it is a relatively small rocket, the rocket production period is as short as one year or less.
The cost is said to be about 3 billion yen. A rocket jointly developed by JAXA and IHI Aerospace.
Development of H3 is in progress as a new rocket. Development is underway by JAXA and Mitsubishi Heavy Industries. Safety, cost, and payload (loading weight) are important for rockets as a new business.
There is a rocket called Falcon 9 in the United States, which has been successful 60 times since the first launch in June 2010. The success rate is 98.45%. Developed by SpaceX of the United States, it has been launched as a commercial rocket.
The name of the Falcon is said to be derived from the movie, Star Wars' Millemium Falcon.
That's all for today.
