Saw up to 95% slip on some of the drive segments due to the 15-20 degree tilt and the sandy terrain. Sol 339 - Another 25 meter attempt. This one was cut short at the start when the right rear wheel ingested a potato-sized rock. The rock apparently jammed between the inner part of the wheel and the drive mechanism, causing the drive current to exceed the preset current limit, resulting in a safe motor stall. We will run this motor in the other direction on sol 340 in an attempt to dislodge the rock.
