The Chinese put a satellite in the L2 (Lagrange point #2) back in Oct - Nov 2018. That satellite is communicating with the lander on the far side of the moon. Note: the far side of the moon receives as much sunlight as the near side of the moon.

You use your mind to figure out how a problem can be solved and you got it right. No wonder you are here on this site and not a sheeple believing whatever the theists wants.???

You have guessed correctly. They put a satellite into orbit around the moon, and it relays signals back to mother Earth.

From the NYT article:
"To overcome the challenge of communicating from the moon’s far side, China had previously launched a satellite called Queqiao, or Magpie Bridge. It now orbits beyond the moon to act as a relay for transmissions to and from the mission control center on the northwestern outskirts of Beijing."
