Per Wikipedia's [Curiosity (rover)](https://en.m.wikipedia.org/wiki/Curiosity_(rover)), it landed nine years ago today at 6 August 2012, 05:17:57 UTC.

This is yet another testament to NASA spacecraft reliability.

Since landing, has anything actually broke or failed yet? 

The wheels are looking a bit ragged, but that can be thought of as normal wear-and-tear for this "model".
