Thanks CTOnews.com for the clue delivery of luggage! CTOnews.com February 17 news, According to Japan Kyodo News Agency, Japan Aerospace Research and Development Agency (JAXA) and Mitsubishi Heavy Industries jointly developed the new main rocket H3 No.1 at 9:37 today in Kagoshima Prefecture Seed Island Space Center for test launch, But unfortunately failed to launch as expected, Finally because the rocket first stage hydrogen oxygen engine ignition automatically shut down and lead to launch mission failure.

Television footage from NHK, the Japan Broadcasting Association, showed a large amount of white smoke coming from the launch pad after the rocket ignited, but the rocket fuselage failed to lift off. A broadcast from the Seed Island Cosmic Center said the main engine had successfully ignited, but the auxiliary rocket had failed to ignite.

According to reports, this is Japan JAXA and Mitsubishi Heavy Industries since 2014 has been jointly developing H2A rocket successor products, the current project lasted 9 years, the total cost has exceeded 200 billion yen.

According to public information, the maximum diameter of the H3 launch vehicle is 5.2 meters, the sun-synchronous orbit carrying capacity is more than 4 tons, the geosynchronous transfer orbit carrying capacity is 7.9 tons, and the payload is about 30% larger than that of H2A, but the launch cost is about half of it.

H3 rocket maximum configuration (H3- 24L) 63 meters high,(excluding load) takeoff mass 575 tons, using solid boosters, first and second stage liquid hydrogen liquid oxygen engine, design goal is to improve the carrying capacity compared to H-2A while reducing launch costs, is Japan's future main rocket.

The LE-9 open expansion cycle liquid hydrogen liquid oxygen engine used this time is a new high-performance rocket engine developed by Japan. Its single vacuum thrust is 1471 kN (about 150 tons) and vacuum specific impulse reaches 422 seconds, which is the world's leading level.

It is worth mentioning that, according to previous plans, the H3 rocket will also be used in NASA's Artemis program, which aims to send humans to the moon.

The impact of this launch failure is still unclear, CTOnews.com will bring you more follow-up reports.
