A Soviet rover on the lunar surface, the Lunokhod 2, has been found on the Moon this week by NASA. The Lunokhod 2 was lost 37 years ago and nobody hoped to find it.
      
      The missing Lunokhod 2 was found on images scanned by Phil Stooke from the University of Western Ontario. He saw a black spot near a small crater. South from the object there was 35-kilometre trek left by the rover, what makes it possible to trace the rover's activities.
      
      The rover was sent to the Moon in 1973, and spent there four months. It measured the magnetic field, driving back and forth over the same route to improve the data. It also made pictures of the Moon’s surroundings and sent thousands of them to the Earth. One day the Lunokhod 2 drove into a small crater, and accidentally covered its heat radiator with soil as it struggled to get out again. That ultimately caused it to overheat and stop working.
