Japan Aerospace Exploration Agency (JAXA) release
H3 Launch Vehicle: Under Development

The H3 Launch Vehicle is Japan's new flagship rocket aiming at achieving high flexibility, high reliability, and high cost performance.

H3 will offer several lineups by selection of two types of fairings, two or three first-stage engines (LE-9), and zero, two or four solid rocket boosters (SRB-3) to deal with various payload sizes and orbits. Its launch capability to the geostationary transfer orbit (GTO) will be the highest ever, exceeding that of the existing H-IIA and H-IIB Launch Vehicles.

H3 is under development to be a successor to H-IIA and H-IIB so that Japan can maintain its autonomous access to space to launch satellites and probes including important missions for the government. We are eager to launch commercial satellites every year as well.

JAXA and its prime contractor, Mitsubishi Heavy Industries (MHI), and other related companies are all hands on deck from the development phase to leverage their experiences to renovate the whole system for producing a low cost, flexible and reliable rocket.

Launch of H3 Rocket Test Vehicle No. 1 (First Report)

Judging that the rocket was unlikely to complete its mission, it sent a command destroy signal on March 7 at around 10:52 a.m. JST [0152 GMT or 8:52 p.m. EST on March 6].

Japan Aerospace Exploration Agency (JAXA) release
Launch Result of the second H3 Launch Vehicle

The Japan Aerospace Exploration Agency (JAXA) launched the second H3 Launch Vehicle (H3TF2) at 9:22:55 (JST) on February 17, 2024 from the Tanegashima Space Center.

The Launch Vehicle flew as planned, and the second stage of the H3 Launch Vehicle was injected into the predetermined orbit. Approximately 16 minutes and 43 seconds after the liftoff, the separation of the CE-SAT-IE was confirmed.

Additionally, based on the post-Earth orbit data from the second-stage vehicle, JAXA confirmed that, the separation signal was sent to the TIRSAT, controlled re-entry of the second stage was performed, and the separation of the Vehicle Evaluation Payload-4 (VEP-4) was verified.

JAXA appreciates all for the support shown in behalf of the launch of the second H3 Launch Vehicle.
