The lunar base is a base for settlers on the moon. It is designed for 2-4 astronauts. It has its own two small nuclear power plants and one solar power plant with many photovoltaic panels. An important part is a large telescope. Satellites orbit the base that look like Star Wars Tie fighters. Communication is provided by the receiver and transmitter. On a lunar base are spherical underground reservoirs of oxygen and energy. Only the overpressure chamber is visible from the underground foundation. I suppose there would be many such small bases on the Moon.
