What is a potential strategic advantage for a future human outpost established on the far side?

Establishing a listening post free from the radio noise originating from Earth.

One compelling justification for sending human explorers to establish a sustained presence on the far side involves minimizing electromagnetic interference. Since the bulk of the Moon shields this region from direct radio transmission from Earth, it also blocks the constant radio noise and signals generated by human civilization on our home planet. Future explorers could utilize this unique radio quiet environment to establish a specialized listening post, allowing for unparalleled sensitivity in observing deep space phenomena without terrestrial contamination, a capability impossible to achieve on the near side.
