The lander had two engines. One partially failed because the bell feel off, creating an asymmetry in the thrust. Their software mostly compensated for it in the horizontal and fully in the vertical. Vertically it exceeded requirements. But the horizontal movement resulted in a tumble.

This is actually excellent engineered recovery during fault/failure modes. It is a success given the mechanical failure of the engine's bell.

FYI, apparently in one of the images the lander took shows the bell on the surface during its approach.

They still did a better job than Isn'treal.

The success was that the software was flexible enough to react to a hardware failure that changed many parameters (a broken nozzle) and land the craft somehow anyway. This should be standard but it isn't.

Japan, successfully crashing perfectly good flying machines since WWII...

What actually happened:

confirmed that the SLIM landed upside down. It's clear from the tweeted photo that it was a "soft landing" since the craft looks fully intact with very little damage.

Article calls this a crash. Fucking garbage journalism. A crash is where it hits hard and gets badly damaged.
