In addition to the landers, it is possible to see the tracks made by the Lunokhod lunar rover! The Soviet Lunokhod lunar rover predates the first successful Mars Rover by some 30 years. (Note: Very cool old-style artists' drawings of the Soviet craft at the Wikipedia links above.)"
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
