Didn't the USA put their flag on the moon? Does this mean the USA owns the moon? Given the strict laws around border / territorial waters, I doubt the UN would recognize any National claim on the Moon and Mars (or any other celestial body for that matter).
It's much more likely that Mars will be claimed by a Corporation (preferably not the Terran Hansiatic League).
