OREANDA-NEWS The head of the American company SpaceX, Ilon Musk, said that the construction of a city on Mars could be the most expensive project in the history of mankind. In his opinion, this will require from 100 billion dollars to 10 trillion dollars.

The exploration of Mars is still one of the main goals of mankind. The head of the well-known American company SpaceX, Ilon Musk, also notes that sooner or later he will succeed not only in realizing a manned mission to Mars, but also in constructing a whole city there. Certain difficulties may arise with this, but they, according to Musk, are more concerned with the financial side of the issue. According to experts, the construction of the Martian city will require at least $100 billion.

These calculations are based on the assumption that maintaining the city will require a lot of cargo from the Earth.
