      I’m not a radio engineer, but my understanding is you’re just bouncing signals off the moon itself, there isn’t a device that echos the signal back or anything. There are mirrors on the moon to reflect lasers back though.

        They left a couple retro reflectors on the moon during the moon landings so we can bounce lasers off them to accurately measure the distance to the moon.

        I think that’s what they meant, cuz a ping to a radio device wouldn’t prove much, just that you are getting signals from up there. A laser would prove definitively.

      Couldn’t such device be delivered without people, like a remotely controlled rover? How does that prove that people made an actual landing on the Moon?

        Because there’s like 6 of em, and we know exactly which mission launched each one.
