What if the US made a base on the Moon in the future (probably far future at this rate), and it was considered to be US Territory there (not a state).

If it were a territory, and once everything is said and done, could they secede from the Union, and devise their own system of government?? Or would the Constitution not allow this at all?

I am meaning to ask this since it's likely that this would eventually happen on earth again (though I'm not hoping it will)

I know this is kind of outlandish but had to ask

If they made one, it would be a military base first, and under their control. There is nothing in the constitution that does not allow a state to secede beyond military might of the federal government

Read Outer Space Treaty

It discusses the UN's treaty on outer space exploration, and shows that it will never be US territory unless they break away from the UN, which will have far reaching consequences, I'm sure.

This really isn't an astronomy question - you'll probably get more informed answers if you post this in the Government area. But I won't let that stop me from putting in my two cents!

Your question really has two parts:

1. Can the US set up a territory on the moon? I think the answer is no, based on treaties that have been signed that state no country can own the moon or any other extra-terrestrial place.

2. But if a territory somehow was setup, could it later secede? Assuming a "friendly" secession, I would imagine all it would take is a passage of a legislation by the US Congress and President. Consider the history around the movement to make Puerto Rico independent - I'm not an expert on this but I believe it has come up for vote on several occasions, though never passed. If this was an "unfriendly" secession, I would think that the Feds would send in the National Guard and/or Army (just as the North did when the South tried its hand at secession in 1861).

Good point ebaines, consider it moved.

I don't see violating a UN treaty or agreement as any real issue for the US, many in the US arer seeing the UN as a unneeded evil or at best an ineffective money pit. Those nations that wish to ignore them face a stern letter unless there is a total agreement.
