FAILED: ALOS-3 - H3 TF-1 (H3-22S) - Tanegashima LC-Y2 - 7 March 2023 (01:37 UTC)

[eeergo]

Building up on the site's recent article about H-III (or H3) final certifications and road to first flight:
https://www.nasaspaceflight.com/2021/09/japan-h3-engine-certification-first-flight/
I believe there's no thread about this maiden flight yet. The development of the rocket itself is mostly wrapped up and launch processing perations have been started, even if there are non-standard operations (not the least finishing the LE-9 certification) being performed - these shouldn't be included in the "H3 development thread" in my opinion.

So opening up with the S1-S2 stacking just announced today:

Second stage has been stacked on the first in the VAB (rocket's Vertical Assembly Building) It is equipped with an actionable moving floor for easy access to various points.

Any launch campaign news?
Or status of ALOS-3?

This is very likely a place holder for NET January 2022, it’s possibly using one of the launch databases I help to maintain:

SFN Japan’s H3 rocket further delayed by engine woes, January 24
First launch delayed to Japan Fiscal Year 2022 = April 2022 through March 2023.

[Masashi] Okada[, JAXA’s H3 project manager,] said a series of nine combustion tests convinced JAXA that it could stick with the LE-9’s current combustion chamber design for H3’s first test flight — carrying Japan’s Advanced Land Observing Satellite-3 (ALOS-3) — by sacrificing some performance. For H3’s second test flight, carrying ALOS-4, Okada said JAXA and MHI would switch to a 3D-printed combustion chamber they think will solve the problem for good.

Iwao Igarashi, MHI: found good solution to turbine vibration problems in engine for H3, proved it was effective. First H3 launch now projected this fiscal year (ends March 31); will announce date after static-fire tests in November. [Sep 13]

The @JAXA_en ALOS-3 optical Earth observation satellite, payload for the 1st flight of the H3 rocket, arrives at Tanegashima by ship today:

Carrim Engineering's "INNOVATOR" carrying "DAICHI-3 (ALOS-3)" has already entered the port. I wonder if it will be taken down in the afternoon.

Japans H3 rocket is going to do a static fire shortly. It will be one more step down before it’s first launch. They will need it to get the Martian Moons eXploration mission to Mars. The mission will do a sample return from Phobos and do a close flyby of Deimos.
