The H3 rocket—11 years within the making—is about for its second launch, following a flubbed debut in March 2023. Japan urgently wants the rocket to succeed, with a second failure risking additional delays and monumental complications for Japan’s house program.
H3 is able to fly once more after its botched maiden launch final yr, with Japan’s Aerospace Exploration Company (JAXA) targeting Wednesday, February 14 at 7:22 p.m. ET (Thursday, February 15 at 9:22 a.m. JST). The 2-stage rocket, assisted by two facet boosters, will blast off from Yoshinobu Launch Complicated on the JAXA Tanegashima Area Middle with a dummy payload and two small satellites on board.
The liquid-fueled H3 rocket flew for simply quarter-hour on March 6, 2023, earlier than mission controllers have been forced to issue the dreaded self-destruct command. The primary stage labored like a attraction, however the identical couldn’t be stated for the second stage, which didn’t alight as a consequence of {an electrical} glitch. This got here as a giant shock to the house company; not like the H3’s first stage, which options newer, extra superior applied sciences and improvements, the second stage depends on confirmed, established applied sciences that had been utilized in earlier Japanese rockets, just like the H-2 collection.

Following the launch failure, JAXA initiated an exhaustive investigation involving workers from numerous departments and former staff. The investigative workforce targeted on {the electrical} system of the second-stage engine, analyzing flight information and manufacturing information, figuring out three potential causes, together with a brief circuit within the ignition system, according to Japan Occasions. Almost one yr later, JAXA, together with associate Mitsubishi Heavy Industries, is lastly prepared to provide it one other go.
The failed launch from final yr resulted within the lack of the $200 million ALOS-3 superior Earth-observing satellite tv for pc. JAXA took a lot of heat for including such an expensive satellite on an inaugural mission. Not prepared to repeat the identical mistake twice, the house company has positioned a dummy payload contained in the fairing (to emulate the mass of an precise payload), alongside a 154-pound (70-kilogram) statement satellite tv for pc constructed by Canon Electronics and a nanosatellite belonging to Japan Area Programs.
The H3 failure additionally threw a severe wrench into Japan’s house plans, affecting its affect within the world house trade. In improvement since 2013, the 207-foot (63-meter) H3 rocket is about to grow to be JAXA’s premier rocket, aiming for a launch price of two per yr over the subsequent 20 years. This rocket, succeeding Japan’s H2-A, gives a streamlined first stage, elevated payload capability, lowered complexity with fewer components, and better adaptability. With an estimated launch value of $38 million, the H3 must be a pretty alternative for each governmental and business clients. Potential future enhancements might enable it to make cargo deliveries to the Worldwide Area Station and the deliberate Gateway house station in lunar orbit.
The implications of the failed inaugural mission prolonged past the lack of ALOS-3. It raised issues about delays in different essential missions, together with these involving worldwide collaborations. For instance, the Martian Moons Exploration mission, initially scheduled for launch aboard H3 in August 2024, has been delayed to November 2026. Ongoing H3 delays are affecting scientific missions (together with Japan’s ALOS-4), but additionally Japan’s business satellite tv for pc launch contracts and its position in worldwide house exploration efforts, resembling NASA’s Artemis program.
For sure, a failed second launch can be double-plus-ungood. Fingers crossed that the subsequent try will succeed.
