Japan successfully launched its new H3 flagship rocket on Saturday, putting its space programme back on track after multiple setbacks including the failure of the rocket’s inaugural flight last year.
The launch also marks a second straight win for the Japan Aerospace Exploration Agency (JAXA) after its lunar lander, SLIM, achieved a “pinpoint” touchdown last month and made Japan only the fifth country to put a spacecraft on the moon.
A relatively small player in space by number of launches, Japan is seeking to revitalise its programme as it partners with ally the United States to counter China.
The H3 lifted off at 9:22 a.m. local time (0022 GMT) and after it successfully released a small satellite, jubilant scientists at the Tanegashima Space Center in southern Japan clapped, yelled and hugged each other.
The rocket also released a microsatellite and a dummy satellite during its flight of nearly two hours.
“The newborn H3 has just made its first cry”, JAXA project manager Masashi Okada, who has led the decade-long development of the new rocket, told a news conference.
“And we need to start preparing for the third H3 launch as soon as tomorrow.”
The H3 is due to replace the two-decade-old H-IIA, which is retiring after two more launches. Another failed flight would have seen Japan face the prospect of losing independent access to space.
The first launch in March ended up with ground control destroying the rocket 14 minutes after liftoff when the second-stage engine failed to ignite. JAXA listed three possible electrical faults in a review released in October but could not identify the direct cause.
Five months earlier, JAXA’s small rocket Epsilon had also failed to launch.
“So happy to see this incredible accomplishment in the space sector that follows on from the success of the SLIM moon landing,” Prime Minister Fumio Kishida said in a post on X.
