Not joking, there is a treaty developed (not signed) to give rights to land on planets to first come, first serve. Some folks are taking this space travel very serious besides Elon. Quoting the website: http://www.spacesettlement.org
The first settlement on the Moon should be able to claim up to 600,000 square miles. Getting to Mars will cost much more and Mars itself is larger than the Moon. Therefore the first Martian settlement should be able to claim up to 3,600,000 square miles, roughly the size of the United States. That would be worth $600 billion at $260 an acre, or $1.15 trillion at $500 an acre. Even at only $100 per acre it would be 230 billion dollars.
Gee, if that kind of money is to be made, no wonder why all those companies are desperately trying to get there. Even I jumped on the bandwagon and signed up with NASA for a ‘boarding pass’ on 4 December, the first flight of testing of the Orion spacecraft destine for a Mars trip in 2030’s sometime.

I am guessing Elon will beat that 2030’s target date with his space mission; I am sure I can beat Elon’s target date if I can get started on the Bmeupteleport.com project.
