The head of SpaceX Elon Musk said what is necessary to create a colony on Mars. About this, he wrote on his Twitter account.

According to the calculations of the entrepreneur, it will take about a thousand Starship ships to build a settlement on the planet capable of functioning independently. To do this, you will need to send at least a million tons of resources and equipment.

Since Earth and Mars come close enough for flights every two years, the delivery of goods will take about 20 years, Musk explained.
He added that each launch will cost SpaceX about two million dollars.

In late September, SpaceX showed reporters a fully assembled starship, which is designed for flights to Mars and other interplanetary missions. According to Musk, the first launch to an altitude of about 20 kilometers will take place in 1-2 months. Earlier, SpaceX successfully tested a prototype Starship: the star hopper rose to a height of 150 meters and made a vertical landing after less than a minute of flight.
