It’s actually amazingly impressive! In contrast, in the past few years Israel, India and even Russia have had disappointing failures trying to land on the moon - not because they’re engineers aren’t as good, but because it’s just really freaking hard to get right and a lot of unexpected things can happen.
The Japanese team lost an engine nozzle and with it about 40% of their thrust as they were mid landing. Losing 1 out of 2 engines is the kind of critical malfunction that usually dooms a mission (like it did once for India); but regardless, their software was able to adjust on the fly, automatically switch into a different flight mode, and still put the lander exactly where they wanted it.
This is a remarkable success where so many talented others have failed. In a couple of weeks, the sun will be shining from the right direction to hit their solar panels and their mission should continue!
