Space

In the winter of 1971, the Soviet Union explored the surface of the Moon with the lunar vehicle Lunokhod 1, the first roving remote-controlled robot to land on another celestial body. Remote control technology is also used in space travel, for instance, the Soviet Lunokhod vehicles were remote-controlled from the ground. Many space exploration rovers can be remotely controlled, though vast distance to a vehicle results in a long time delay between transmission and receipt of a command.
