6 times to the moon and nobody thought to bring a flashlight or a radio to send a beacon back to Earth to prove to one and all for all time we made it. But the Russians sent up Sputnik and the only thing it did was beep Just to prove they did it. Is nasa a fraud or just full of extremely incompetent people?
Your assumption is incorrect. NASA did take all kinds of beacons to the Moon.
- Radio transmitters were used during the missions, for transmitting voice, telemetry and video.
- Each mission left an instrument package named ALSEP. These included radio transmitters, and they ran until 1977 when their RTGs ran out of power.
- Laser reflectors were placed, these can be pinged from Earth
- An optical beacon would be of limited value as it'd take a lot of power to make that visible on Earth
