It was just announced that China has successfully put a probe on the moon. The Chinese mission, called Chang'e-4 has successfully achieved the first "soft" landing of a craft on the far side of the moon, and has deployed a robotic rover. Chang'e, named for the Chinese moon goddess, has sent back pictures thanks to a communication relay satellite, Queqiao, which was previously launched into a halo orbit back in May.
The communications system being used is actually quite fascinating. The far side of the Moon is pretty much the only place in the solar system where you can't directly talk with Earth, ever, because it's always facing directly away and blocked by the Moon itself. The Moon turns too slowly to have a geostationary (actually LUNAstationary) orbit, so you can't just park a satellite overhead, and a constellation of comsats for one mission is too difficult and expensive. So the Chinese looked to Harrison Schmitt's suggestion and put a single comsat in a lazy orbit around the Lagrange-2 point. Schmitt, the last man on the Moon and the only actual scientist to go there, lobbied vehemently to have Apollo 17 land on the far side, and the audacious L2 proposal was considered very bold. But it is working perfectly!
