NatCapVidMo Day 17: Lunokhod-1

40 years ago today, Lunokhod 1 landed on the surface of the Moon and began taking pictures. It was only expected to last 3 months, but wound up staying operational for 11 months, and even today, though it hasn't transmitted any electronic signals back to earth since 1971, its reflector is still being used by by earth-based astronomers. Well done, little lunar robot! Maybe someday soon we'll come back up there to thank you for all your good work in person.
