Here is the answer for your question:
Man-made satellites are important and impressive pieces of technology, but they do have some down sides. Satellites are very costly, hard to maintain, and not always reliable. These disadvantages have to be weighed against the many benefits from satellites. They take photographs of various things on Earth and in space, in visible light or in other areas of the electromagnetic spectrum, and send and receive a variety of signals for televisions, cell phones and GPS devices.
Disadvantages:
Costs are Prohibitive
Satellites are expensive.
Signal Reception can be Spotty
satellites is their somewhat unreliable signal.
Propagation Delay is a Problem
Propagation delay is the term used to describe the length of time it takes for the satellite to communicate with Earth.
There are No Repair Shops in Space
Satellites used to be impossible to maintain or repair in any way

ADVANTAGES AND DISADVANTAGES OF ARTIFICIAL MOON
Across history, human development has relied upon the infinite resources available on earth. But the moon may actually be a treasure trove of rare resources vital to earth’s future. And now, nations are looking upwards to a potential lunar gold rush.
Geological surveys show that the moon contains three crucial elements:
Water – vital for supporting life and agriculture beyond earth and it can be converted into rocket fuel;
Helium3 – a rare element sought for future developments in the energy sector like nuclear fusion.
Probable effects of moon mining include weather, aging, agriculture and aquatic life. The moon has a mass of 73q tons. Some calculations show that if one metric ton was removed entirely from the moon each day, it would take 220 million years to deplete 1% of the moon’s mass. This wouldn’t be enough to cause a change of orbit or effect the gravitation that causes tides.
The biggest concerns are environmental damage and the ethical consequences of moon-mining. Considerations include impact on future generations, importance of the moon’s role in human culture, stakeholders in lunar heritage as well as the visual impact from earth.
The National Aeronautics and Space Administration (NASA) also stress that there is no sure way of knowing what will work and what won’t. “Until we get there and fight it out, we’ll just have to wait and see.”
