We need to use the Moon for all kinds of industries, Water, for rocket fuel, and oxygen to breath. The lunar soil, for mining Thorium, for Nuclear electrical power, materials to build lunar colony structures out of, and of course telescopes, to see what is out in space.

Put telescopes on the far side of the Moon

Plans to return to the Moon are getting serious. Last month, US President Donald Trump declared that the next time US astronauts blast off, they will be headed to our rocky satellite. In September, the European Space Agency made its strongest call yet for the installation of a permanent, human-inhabited village at the lunar southern pole.

 From article, (Plans to return to the Moon are getting serious. Last month, US President Donald Trump declared that the next time US astronauts blast off, they will be headed to our rocky satellite. In September, the European Space Agency made its strongest call yet for the installation of a permanent, human-inhabited village at the lunar southern pole. China’s National Space Administration is pursuing a human outpost there, among other lunar projects, and private entrepreneurs are enthusiastic about mining minerals on the Moon and making rocket fuel for further space exploration.

But these initiatives are more technical and economic than scientific. Unless we start planning now, they will lack an exceptional asset — a lunar radio telescope. This would be uniquely poised to answer one of humanity’s most profound questions: what are our cosmic origins?

A radio array able to capture these data would probably use millions of simple radio antennas deployed over an area a hundred kilometres across on the Moon’s far side, operated by humans and robots. Infrared telescopes of unprecedented scale could be built in cold craters near the lunar south pole, in permanent shadow where temperatures as low as 30 kelvin have been measured. With no atmosphere to absorb radiation and block signals, Moon-based scopes could yield fantastic images of exoplanets and the oldest galaxies in the Universe. Using the Hubble Space Telescope and the International Space Station, launcher included, as guides, I estimate that all these telescopes would cost no more than 5% of other planned lunar operations.)
