SLIM
SLIM (Smart Lander for Investigating Moon) demonstrated precise pinpoint landing technology, touching down within 55 metres of its target — far exceeding the original 100 m goal. The lander came to rest inverted due to a main engine failure during descent, causing power issues, but still transmitted scientific data.
