Big up and good luck to Japan. The information obtained from the SLIM mission will pave the way for a men on the moon mission within a decade, hopefully.

Nice to hear and fingers crossed. More the fun now to look at the moon through my 天体望遠鏡.

confirming a lot of data has been obtained

Well done JAXA! Hopefully more will be learned about the moon, and its assembled bits of matter from Earth, Theia and elsewhere, and what is learned will be of benefit to us all.

A giant wireless charger?

"JAXA had hoped to shed light on the mystery of the moon's possible water resources -- key to building bases there one day as possible stopovers on the way to Mars." So now I know what the real objective is. By the time they get to that stage, don't you think climate change, war, and contagions would have decimated humans? Resources spent on these fantasy excursions could be more effectively used on practical solutions here on Earth.

Well done Japan!

This is a fascinating article with much more information than many of the pablum articles common in Japanese press. I hope that we get more information in the future from this probe. Thanks  JT

Go Jaxa.

Better to control expectations, as Govt. run enterprises never perform very well. Funny thing about ownership and accountability. Govt employees own nothing.

Serious new space technology happening in private sector globally, as Govt. just a big dumb buyer and user.

No mention that the lander flipped over, let's hope they are brave enough to release the rovers picture of the lander.

Employees of a private space firm own nothing as well. We can see how well their safety record ends up being.

Happening in the US. FTFY.

I really hope they can get this working, but hope even more that they nailed the landing to within 100 meters, as that was the major objective.

If they succeeded, this will be highly useful tech for future landings, both for JAXA and for the Artemis program.

What a ridiculous, unfounded generalization.

Hoping this works. Secretly many people are surely encouraged by this possibility.

If it is inside a crater, let us also hope that the rim's shadow does not cut out too much 'western' setting sunshine. Oh, and that the thin film solar panels are not coated in too much moon dust.

We are with you, so be super smart, Smart Lander for Investigating (the) Moon!!!

Face saving gestures but you do whatever you can to get the maximum amount of data possible.

Whatever the case everyone has made mistakes with their robot landings and have learned from them. JAXA has achieved quite a number of accomplishments already and will do some more.

If there is a power problem in this droid lander I have faith they can work it out.

Go JAXA!

So, if they can’t get it going are they going to do another mission to retrieve it? Or, are they going to spread their garbage to the moon.

-7 ( +2 / -9 )

Please give JAXA some face. They landed on the moon.

1 ( +4 / -3 )

They are teaming with India for the next moon lander. So maybe they already know they have weaknesses in that area and need Indian help.

-4 ( +0 / -4 )

Isn't lunar night (two weeks in length) about to cover the area where the lander is?

0 ( +2 / -2 )

AI (and me) we have of course a little less optimistic outlook: The temperature on the surface of the moon can vary drastically between lunar day and night time. During lunar daytime at the moon’s equator, the temperature can reach a blistering 250°F (120°C or 400 K), while at night, it can plummet to -208°F (-130°C or 140 K) In certain spots near the moon’s poles, temperatures can drop even further, reaching -424°F (-253°C or 20 K) Based on these temperature ranges, it is unlikely that small solar panel driven batteries would be able to withstand the extreme temperatures on the moon’s surface. However, I do not have information on the specific type of battery you are referring to. If you have more information on the battery’s specifications, I may be able to provide a more accurate answer.

Employees of a private space firm own nothing as well. We can see how well their safety record ends up being.

Odd someone on JT actually believes they know stock option packages of many employees in the rapidly expanding global private space industry.

Private non-public/listed companies do not disclose pay and stock packages to the public, so this person is clearly misguided and likely very envious.

TALENT goes where they have MORE $incentives and Greater Professional Discretion to pursue their space tech culture, serious budget and risk taking vs. CHEAP slow Govt. bureaucrat' trying to control their technology.

JAXA, NASA, etc. Govt. run Space Agencies strictly for those who wants steady paycheck, not cutting-edge professional work with $chance. Govt's big dumb buyer with ability to print$ with no talent to create serious tech, just like every other tech industry that sells to Govt.

Maybe they can find something lying around up there to salvage that the US left behind when they landed human beings up there more than a half century ago.

-5 ( +0 / -5 )

There has to be very little quality control if they couldn't plan for anything like this happening.

I agree it is odd you think you know what the options packages are and whether they have a precise value.

Govt's big dumb buyer with ability to print$ with no talent to create serious tech, just like every other tech industry that sells to Govt.

Some talent want the steady paycheck and reasonable working conditions. We've seen clearly the lack of intelligence at the head of many private companies.

touchdown.... the Japanese machine simply does not work.

Japan became the fifth country to achieve a soft lunar landing.

no evidence of any Japanese soft landing!

Japan should ask for Chinese help and technology..

-5 ( +0 / -5 )

Today we have images from the secondary rover showing that the touchdown was just 55m from the target. Impressive.

SLIM made a precise landing at 25.24889 East, 13.31549 South on the slope of Shioli crater, 55 meters from the target point, Shinichiro Sakai, SLIM team project manager at JAXA,

We also know that the lander used only 1 of 2 rockets for the landing. One of them failed.

Sakai revealed however that one of the two main thrusters likely failed during the final landing phase. This took place from an altitude of 50 meters to touchdown, resulting in unintended lateral motion above.

And because 1 thruster failed in the final stages, the lander ended up "on its nose". Here's an image showing this attitude: https://i0.wp.com/spacenews.com/wp-content/uploads/2024/01/20240125-4_01_LEV-2-JAXA-cr.jpg

Don't forget that this entire mission was supposed to last just a few days, so they are already getting valuable data, even with the thruster and landing problem.

The data during the landing shows that 2 obstacles were detected and avoided. Nice. That worked as designed.

LEV-1 and LEV2 have been working. These are the 2 "rovers" included in the payloads.

Nicely done JAXA and team members!

no evidence of any Japanese soft landing!

Lots and lots of evidence.
