The first Lunar rover show
NASA wanted you to feel that you were part of the mission.
Apollo 15 was the first mission to be equipped with a Lunar rover. The rover was basically a stripped down army jeep. On the jeep a camera was attached that could be controlled from Houston. They were trying to give the viewer the feeling of being a third astronaut on the moon. These are not my words but those of NASA (Video part 2). Totally bizarre if you think about it today, but you grandparents fell for it.
