Since the GPS satellites are so far up and the Moon has one side always facing earth could the GPS system work for locations on the Moon?

Well, the Arizona meteor crater is about 50,000 years old. It is a crater about 1.2 km in diameter and was formed by an impactor about 50 meters in diameter. I don't know which impact occurred 40,000 years ago.

But we don't really know if a similar impact occurred in the ocean or in a polar area during the last 50,000 years That being so we could reasonably expect a similar impact in the next 10,000 years. That's really a guess on my part. But to be on the safe side, I think I'll add a 2nd floor to my house as protection from an impact.

\\ I wonder if it will be sufficient protection from this https://en.wikipedia.org/wiki/Meteor_Cra...

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
