Who Owns the Moon?
Within the next ten years, the U. S., China, Israel, and a crowd of private companies plan to set up camp on the moon. So if and when they plant a flag, does that give them property rights?
A NASA working group hosted a discussion this week to ask: Who owns the moon? The answer, of course, is no use. The Outer Space Treaty, the international signed by more than 100 countries, states that the moon and other celestial bodies (天体) are the province of all mankind. No doubt that would annoy all of the people throughout the ages, like monks from the Middle Ages, who have tried to claim the moon was theirs.
But ownership is different from property rights. People who rent apartments, for example, don’t own where they live, but they still hold rights. So with all of the upcoming missions (派遣团) to visit the moon and beyond, space industry thought leaders are seriously asking themselves how to deal with a potential land rush.
“ This is a very relevant discussion right now. We’ve got this wave of new lunar missions from around the world,” said William Marshall, a scientist in the small-spacecraft office at NASA, but who spoke this week at an event hosted by NASA’s Co Lab, a collaborative(协力完成的) public-private working group. He was speaking from his personal interest and not on behalf of the agency.
To be sure, the United States aims to send astronauts back to the moon by as early as 2015, in a mission that would include a long-term settlement. China and Israel, among others, are also working on lunar projects. And for the first time, several private groups are building spacecraft to land on the moon in an attempt to win millions of dollars in the Google Lunar X Prize. Some participants say that they plan to gain some property rights in the mission.
