Japanese Space Program

"ispace, a global lunar exploration company, announced today that it was able to successfully establish a stable attitude for its HAKUTO-R Mission 1 lunar lander, as well as confirm stable power supply in orbit. It was further confirmed that there were no deficiencies in the lander’s core systems, and that initial critical operational conditions were achieved."

wonder what caused the problem with the second engine?

They use spark ignition for Engine.
i don't know how they kickstart the Turbopumps before the Propellants are ignited, probable by helium pressure from propellant tanks.

Thanks Michel Van, I suppose we will only know when they release the details of the investigation.
 
According lates news is JAXA in serious problems.
The Japan media have crucified JAXA and Mitsubishi Heavy Industries,
About the H-3 failure and choice to launch expensive Satellite.
what JAXA describe as electrical problem with the ignition system.

Since the Japanese culture NOT tolerate failure, the H-3 program is in danger.
The easiest way to prevent failure is simply cancellation the program,
Let's hope the Japanese politician are not so stupid...
 
Sooo ...SPLAT!

Not a good week for private space thingies.
 
Excuse my snarkiness above. I hope Japan will continue to press the envelope. If we do not learn to leave this rock, we will die on it.

An imperative of nature.
 
according Scott Manley

Hakuto-R lander had issue to determine its high over surface
and run out of Fuel and hit hard the Moon
They used several method to determine distance,
But flight computer not used installed the Radar altimeter for that !

who to hell design that system ?

XRISM Mission Ready To Explore Universe’s Hottest Locales
Japan’s XRISM (X-ray Imaging and Spectroscopy Mission, pronounced “crism”) observatory, expected to launch Aug. 25 (Aug. 26 Japan local time), will provide an unprecedented view into some of the hottest places in the universe. And it will do so using an instrument that’s actually colder than the frostiest cosmic location now known.

Launch Schedule of the second H3 Launch Vehicle (H3TF2)
December 28, 2023 (JST)

Japan Aerospace Exploration Agency

 The Japan Aerospace Exploration Agency (JAXA) hereby announces the launch schedule of the second H3 Launch Vehicle (H3TF2: Test Flight No.2） as follows.
 The H3TF2 will carry the Vehicle Evaluation Payload-4 (VEP-4) to conduct the flight demonstration. In addition, we will capitalize on the excess launch capability of the H3TF2 by providing launch and orbit insertion opportunities for two small secondary payloads (piggyback payloads), CE-SAT-IE and TIRSAT.

Launch date: February 15, 2024
Launch Window: 9:22:55 (JST) through 13:06:34 (JST)
 The time is the 24-hour clock
Reserved Launch Period: February 16 through March 31, 2024
Launch site: Yoshinobu Launch Complex at the JAXA Tanegashima Space Center

--------------------------------------------------------------------------------------------------------------


Launch window confirmed as 00:22:55-04:06:34 UTC, February 15.

Note that after deploying the hitchhiking payloads CE-SAT-IE & TIRSAT into a 675 km SSO, the 2nd stage de-orbits & only afterward does the dummy payload (named VEP-4 - Vehicle Evaluation Payload 4, 1st 3 were on H-II 1st launch (TF1) and the first 2 launches of H-IIA (TF1/2) respectively) got deployed while on the way down to test the payload separation mechanism.

Because of the difficulties with the H3 Japan delayed the launch of the MMX mission to 2026. New return date is 2031.

Japan to Delay Mars Moon Exploration by 2 Years to 2026

TOKYO (Jiji Press) — Committee on National Space Policy on Tuesday broadly approved the idea of delaying the planned launch of a Martian moon probe by two years to 2026.
japannews.yomiuri.co.jp japannews.yomiuri.co.jp
 
The Japanese space agency JAXA confirmed the two-year delay in the launch of the Martian Moons eXploration, or MMX, mission, blaming it in part on the H3 rocket that will launch the spacecraft.

Japanese Mars mission launch delayed to 2026

The launch of a Japanese mission to return samples from the Martian moon Phobos, previously scheduled for later this year, has slipped to 2026.

Japan makes history with tense, successful moon landing

Japan makes history with tense, successful moon landing Japan's SLIM “Moon Sniper” spacecraft made a successful lunar landing Friday, making the country just the fifth to robotically land on the moon.
spacenews.com spacenews.com

Congratulation, Japan is the 5th country to soft land on the moon.

Sadly, the solar panel is not working.
 
The Moon "race"
1-USSR : Luna 9, February 1966
2-USA: Surveyor 1 (1966 too)
3-PRC: Chang'e 3, 2013
4-India: Chandrayaan 3, 2023
5-Japan: SLIM, 2024.
 
"It was at this moment Japan moon lander knew - he had fucked up"

"Whatever can go wrong - will go wrong. In the worst possible way."

"The Moon is a harsh mistress."
 
Not looking good at all for SLIM, landing upside down on the surface of the Moon thereby potentially covering the solar panels and stopping SLIM from recharging the batteries. Though JAXA are saying that the mission to land on the Moon is still a success. I wonder if JAXA will design a successor lander and try again.
