Mankind must explore space and settle on other planets.
This was stated by Elon Musk, the owner of the "SpaceX", "Tesla" companies, as well as the "X" social network.
"Humanity should have a base on the Moon and cities on Mars!" he wrote on his social network page.
Elon Musk reminded that it has been 50 years since the last landing on the moon and added that this cannot be considered our highest achievement as a civilization.
