Japan’s new H3 rocket reaches orbit for 1st time (video)

Japan’s new H3 rocket reaches orbit for 1st time (video)
Share on FacebookShare on Twitter

The second time was the charm for Japan’s new H3 rocket.

The H3 reached orbit and successfully deployed a satellite this evening (Feb. 16), rebounding from a failure on its debut flight last year and getting back on track to becoming Japan’s workhorse rocket of the future.

“I was so moved!” a commentator said during a webcast of today’s launch provided by the Japan Aerospace Exploration Agency (JAXA). “The story of H3 will begin from today.” (The original comments were in Japanese; JAXA provided an English translation in real time.)

Development delays, and a failed debut

JAXA and Mitsubishi Heavy Industries have been developing the H3 for the past decade. The expendable, medium-lift rocket will take the reins from the nation’s venerable H-2A, which has been flying since 2001 and is set to retire later this year.

The two-stage H3 stands either 187 feet or 207 feet (57 or 63 meters) tall, depending on the choice of payload fairing. The first stage is powered by either two or three liquid hydrogen-liquid oxygen LE-9 engines, which were newly developed for the H3. The upper stage features a single LE-5B-3, an advanced variant of the upper-stage engine on Japan’s H-1 and H-2 vehicles.

The H3 can be outfitted with two or four solid rocket boosters to increase its thrust. In its burliest configuration, the new rocket can haul more than 7.2 tons (6.5 metric tons) of payload to geostationary transfer orbit (GTO), according to its JAXA spec sheet. The H-2A, by comparison, can deliver about 4.4 tons (4 metric tons) to GTO. The H3 will also be significantly cheaper to build and operate than its predecessor, according to JAXA officials.

The H3’s debut was originally targeted for 2020, but the timeline slipped substantially, partly due to difficulties in the development of the LE-9. The new rocket finally launched for the first time on March 6, 2023, on a mission that aimed to send the Advanced Land Observing Satellite-3 (ALOS-3), also known as DAICHI-3, to orbit.

Things did not go well that day, however. The H3’s second-stage engine failed to ignite due to an electrical issue, and the satellite was lost.

Bouncing back

It took nearly a year for the H3 to get off the ground again. The rocket lifted off from Japan’s Tanegashima Space Center today at 7:22 p.m. EST (0022 GMT and 9:22 a.m. Japan Standard Time on Feb. 17).

H3 carried two small Earth-observation satellites, called CE-SAT-IE and TIRSAT, on its mission today. The main payload, however, was a 5,900-pound (2,600 kilograms) mass simulator, which stood in for a big-ticket spacecraft.

“The primary purpose of this mission is to evaluate the performance of the H3 rocket and its payload deployment mechanism,” EverydayAstronaut.com wrote in a mission description.

The early stages of the launch went entirely according to plan; the H3 notched all of its required milestones on time — most notably, considering what happened last March, the ignition of its upper-stage engine a little more than five minutes after liftoff.

The upper stage reached orbit, then deployed CE-SAT-IE about 17 minutes after liftoff — again, right on schedule. The success elicited applause and high-fives from team members in mission control.

TIRSAT and the payload simulator will be deployed later in the flight, but we’ll have to wait to hear how those events went; JAXA ended the webcast shortly after CE-SAT-IE’s separation. The agency will hold a press conference later to discuss the flight, commentators said during today’s launch.

Their enthusiasm, and that of the folks in mission control, suggests that JAXA will regard today’s mission as a success no matter what happens with those other two payloads. The H3 has successfully deployed a satellite, after all, so it has earned its wings.
