cant be true ,they landed on an asteroid and returned back samples . few small rovers too i think.
May be because lunar gravity is much higher than asteroids?
Anyway, they still failed to land on moon and it was agreed between ISRO and JAXA that ISRO will land on the moon and that technology will be the basis Indo Japanese joint lunar sampling mission.

Strange ISRO able to make orbitor, lander and rover but Japan not able to make lander. I think Japan just send a mission to moon, if I m not wrong

JAXA moon lander didn’t account for massive lunar craters, when finding the landing spot. autonomous landing calculations went haywire from there.

Failed after trying for many years.

India was collaborating with moon landing with Russia but separated Chandrayaan-2 after Russian failure. That’s where Japanese and Indian cooperation begun.
Not sure if its the failures but in general our efforts are mostly going independent in the core side with partnership in payload type work? Japan's rockets give a feeling of unreliability and they do have quite a bit of failures for advanced component level supply chain....leading to believe more bureaucracy level issues playing role.

It was a technical glitch which they ignored caused them faliure it was altitude miscalculation
Possibly model anomalies and biases....overfitting and underfitting and both may be fatal. This stuff does involve some luck as the science behind it is not 100%....can happen to anyone and ofcourse there may have been other anamolies as long as its not bureaucracy related.

For the Vikram lander, did all the sensors finally work, as well as the 4 800N engines? The landing went off superbly, but it would be comforting to know that everything worked anyway. ISRO did say that even if all the sensors, and 2 of the engines fail, a landing is very likely. Still...

All of them worked flawlessly....the fact that it landed within 360m from the targeted landing site is proof of its excellence....it landed with less than 1m/s touchdown velocity
