When the astronauts discovered the Moon was NOT cheese they packed up their bags and went home.
A little cow told me that.
But, seriously, folks, there are some good arguments for setting up an observatory on the far side of the Moon, that I am sure everybody here can understand.
Hint: Less RFI and less light pollution.
The downside is all the data collected would have to be relayed around the moon to be transmitted back to Earth either from a satellite or from a stationary high gain antenna on the other side.
