Back before dubstup and chillwave there was a decade called "the nineteen seventies" which capped off a delicious space race between the US and Russia. Also, other things happened. While America was busy shipping humans up to the moon
, Russia managed to get two robots up there, the Lunokhod 1 (pictured, in a photo apparently taken in 1904) and Lunokhod 2. They were lost a few years later, but have recently been rediscovered by the Lunar Reconnaissance Orbiter, and the Lunokhod 1 has been put back in use for one of its original purposes: laser ranging. A team from UC San Diego managed to get a lock on the bot and bounced 2,000 photons off the rover's laser retroreflector on their first try. They'll be using Lunokhod 1 and some Apollo-planted retroreflectors to test Earth-Moon distance at millimeter precision to test Einstein's theory of gravity.
