On Sol 3658 (yestersol), the Mars Curiosity had a checkup look at its wheels using the arm-mounted MAHLI camera. Those wheels have seen better days, but they're holding up and have many more kilometers of driving left in them.
Fun fact: See the holes in the second image? Those leave marks in the sand and are used to determine distance. They also spell out "JPL" in Morse Code:
.--- J
.--. P

火星に行ったCuriosityの車輪のどアップ＠＠！
あ、穴がＴＴ。なかなか過酷らしい･･･
規則性のある穴は、わざとで、印を残し、距離を測る･･･らしい。モールス信号。。。ほほー
