Don't be over the moon yet! Buying a piece of lunar landscape still a distant dream

Signed by 104 countries, the treaty became the basis of international space law. According to the treaty, "Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means."
However, the outer space treaty states that governments "shall bear international responsibility for national activities in outer space, including the Moon and other celestial bodies, whether such activities are carried on by governmental agencies or by non-governmental entities."

The deed is "officially registered and recorded by The Lunar Registry at New York City and legally certified on 25 June 2018."
It is signed by "Jean Sebastian Belanger, Registrar on behalf of the Lunar Republic Socielty."
