Japan Launches Next-Generation H3 Rocket Successfully On Third Attempt

On Saturday, Japan’s space agency hailed the successful launch of its new flagship rocket, H3, following years of delays and two prior unsuccessful efforts.

JAXA-proposed H3 rocket marketed as adaptable and cost-effective was launched from the Tanegashima Space Center in southwestern Japan at 9:22 am (0022 GMT).

The new launch comes after Japan successfully landed an unmanned probe on the Moon last month, although at a wonky angle, making it only the fifth country to do so.

The H3, developed by JAXA and Mitsubishi Heavy Industries, is the successor to the H-IIA launch system, which debuted in 2001.

JAXA noted, “Designed for high flexibility, high reliability, and high-cost performance, the craft will maintain Japan’s autonomous access to space”.

The first H3 launch in February 2023 was aborted due to ignition issues, which left the rocket stationary on the ground.

Technical issues caused the destruct command to be issued shortly after launch on the second attempt in March of last year.

The H3, which carries two tiny satellites later had its ignition system improved.

One of the microsatellites is expected to help with catastrophe prevention by gathering images and videos.

The other, equipped with an infrared ray sensor, is designed to detect the factory operation ground.

The microsatellites’ separation has also been confirmed.

“We will keep analyzing the sequences after successfully putting the rocket into orbit”, the JAXA continued.
