We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

So I guess this is the US government admitting we don't own the moon ๐
That's already the case due to a treaty.
Treaties are made to be broken.
I'm more interested in where the "border" is in this case. At what altitude are you no longer considered to be in US airspace?
There's not really any definite border. FAA controlled airspace generally ends at flight level 600 (around 60,000 feet, although flight levels are defined by air pressure not distance from the ground, so the actual altitude can vary). Above that will be uncontrolled airspace, though that doesn't necessarily mean the US won't claim sovereignty there.
The Outer Space treaty, generally considered the first step in establishing space law, stipulates that "outer space" is for the benefit of all mankind and not subject to sovereignty claims by any country. However there isn't a legal definition of where outer space begins. The Karman line (100km) is a common practical definition. However the US has flown spacecraft (notably the shuttle) below 80km above Canada, without asking for permission first.
Practically speaking, there are as yet not enough craft flying at these kinds of altitudes for real legislation to be necessary. The spacefaring countries mostly work it out between them on a case by case basis.
I just want to see the news report about Canada shooting down an unidentified craft at 80km.
