So I'm watching Race to Mars tonight on the Science Channel and a commercial for Tank on the Moon is shown that deals with the Russian moon rover. The what?! OK, I admit it... I had not known about the Russian Lunokhod program before. Apparently back in the late 60's the Russian not only developed the first lunar rover decades before NASA, with their Mars rover, but actually put it on the moon. Either I did know this tidbit and forgot about it or I somehow missed it over the years.
