Sol 466 (May 16, 2005): Results from the sol 465 drive were good
(some
wheel cleats are clean and the rover is making forward progress), so
the
team commanded a drive that, if there were no slippage, would roll 4
meters (13 feet), consisting of ten 40-centimeter (16 inch) steps.
Opportunity gained an additional 2.7 centimeters (1.1 inch).
