Wheel Condition Check
Curiosity Rover used its Hand Lens Imager (MAHLI) around 4 pm (local time) during mission Sol 1355, May 29, 2016 to acquire a set of images of its wheels. These were periodic checks to allow the rover's engineers to assess the accumulated wear and tear to its 6 aluminum wheels.
The MAHLI camera is located on the end of the rover's 2-meter long robotic arm. Images of the wheels are acquired by extending the arm away from the rover and then lowering it close to the ground.
I have corrected the rotation of the image and enhanced the colours a little.
For scale the rovers wheel diameter is 50 centimeters or about 20 inches, width is 40 centimeters, or 16 inches The distant base of the Gale crater rim mountains, seen at the top of this image were ~30 kilometers (~19 miles) from the rover's location in May 2016.
Got me wondering how it's looking now.
A little rough (Sol 4634, August 19, 2025)
Damn she's still perservering on some rough looking wheels💪
Thanks for looking it up and sharing the image🫡 +1
They may be a little rougher these days, but the rover is still roving :)
The tread depth is just fine. Got another million miles on those babies!
