It’s worth nothing. The cost of getting it would far outweigh the value of the materials.
Put it another way you know exactly where $500 is buried in Antartica. Would you go get it?
seems like it could be incredibly useful some day.
Scale that up/ There’s a billion dollars buried in Antarctica. You have the gps coordinates. All you gotta do is go get it...
I would not go to Antarctica for a single $500 dollar buried gem. But if there were billions of these gems it might at some point be cost effective to get some kind of enterprise going to efficiently find and extract them.
Of course, this presumes a plan to make it cost effective at scale would be conceived and competently implemented...and NASA is a government agency....
The value is not having to ship construction material into orbit in the first place.
