No one should! But then why does holier-than-though America think they can do what ever they want with it?
NASA sent 2 spacecrafts crashing and slamming into the moon in the hope of finding water molecules. Nothing much came of it.
What if Russia, China, Nth Korea or India wanted to do simiar things to the moon or worse, actually blow parts of it up in order to research? Would the US and NASA stop them? Who has the right to draw the line?
I'm sure they are doing all their analysis on it but why also waste millions on doing something like this when their economy is in recession?
