Following a setback in its initial attempt last year, Japan’s cutting-edge H3 rocket has successfully reached orbit in a significant test conducted on Saturday.
The launch site for the H3 rocket was the Tanegashima Space Centre located in the country’s southwest and the launch took place after a delay of two days caused by unfavorable weather conditions.
Upon reaching an altitude of approximately 420 miles (670km), the rocket deployed two satellites into orbit, according to a statement by the Japan Aerospace Exploration Agency (JAXA).

The debut of the H3 rocket in March last year ended in failure when the second-stage engine did not ignite, likely due to electrical issues, resulting in the destruction of the rocket and its satellite payload, ALOS-3, 14 minutes after take-off.
JAXA president Hiroshi Yamakawa expressed immense relief at the news conference following the H3’s successful second attempt, commenting on the significant first step towards Japan’s aim of achieving autonomous access to space and competing in the global satellite launch market.
Following a series of accomplishments, including an unmanned spacecraft being sent to the Moon last month, Saturday’s event adds to the Japanese space program’s streak of successes.
Japan plans to retire its current primary rocket, the H-2A, in favor of the H3 after two remaining flights.
Joy and relief were palpable at JAXA’s control center as the rocket performed successfully, with live footage showing team members cheering, embracing, and some shedding tears of happiness, as reported by NHK television.
Masashi Okada, the JAXA H3 project manager, deemed the flight “perfect”, stating that the rocket had achieved all of its assigned missions for that day and conveyed a sense of immense pressure being lifted from his shoulders.

The rocket was visually distinguished by thousands of stickers affixed to it, displaying messages of support from people throughout Japan.
Accompanying H3’s launch were two functioning microsatellites – the observational satellite CE-SAT-IE and TIRSAT. An ALOS satellite replica, referred to as VEP-4, was also aboard the rocket but was not meant to be separated.

FAQs about Japan’s H3 Rocket
- What is the H3 rocket? – The H3 rocket is Japan’s latest generation flagship rocket, designed to secure the country’s independent access to space and compete in the international satellite launch market.
- What happened during H3’s first launch? – H3’s first launch was unsuccessful as the second-stage engine failed to ignite, likely due to electrical problems. The rocket and its payload had to be destroyed shortly after.
- What did H3 carry on its successful launch? – On its successful launch, H3 carried two microsatellites (CE-SAT-IE and TIRSAT) into orbit, along with a mock-up of the ALOS satellite, VEP-4.
- What will happen to Japan’s current primary rocket, the H-2A? – The H-2A rocket is scheduled to be retired after two more flights, making way for the H3 as Japan’s leading rocket for space missions.
Conclusion
The successful orbit attainment of Japan’s H3 rocket marks a momentous achievement for JAXA and the nation’s space objectives. After overcoming the challenges from its first launch, the H3 has proven its capabilities and stands as a beacon of Japan’s commitment to advancing in space exploration and satellite launch services. The project’s success further solidifies Japan’s standing in the aerospace sector and opens the door for more ambitious missions in the near future.
