Moon-base Concepts
I find it rather strange that after all those voyages to the moon during the 1960's we are still wallowing around in earth orbit and lacking a moon base. After all, the trip to the moon involves only a few days and doesn't place any extraordinary demands on human physical tolerance as long-duration spaceflights would. Neither do the voyagers experience the psychological stress of having to observe the Earth slowly receding into the foreboding darkening distance.
Instead, astronauts arrive within a few days and our home, our planet Earth, is always comfortingly visible in the moon's sky. There is also the ease of communication. Unlike other distant planets, such as Venus or Mars, communication with home-base takes just a matter of seconds, and not many minutes of delay between transmisions.

At Mars’ closest approach — about 35 million miles away — the delay is about four minutes. When the planets are at their greatest distance — about 250 million miles away — the delay is around 24 minutes. This means that astronauts would need to wait between four and 24 minutes for their messages to reach mission control, and another four to 24 minutes to receive a response.

That's a whopping forty-eight minutes for a transmission and a response. Not very conducive to conversation.

However, nearness to Earth does nor eliminate the challenge of living on a moon that has no atmosphere and offers absolutely no protection from the deadly radiation relentlessly showering down on its surface from both our the sun and from interstellar space.
So moon-base designers must take this hazard into serious consideration in order to provide the necessary shielding to safeguard human health.
