"What are they hunting for?"
Hopefully a place to put a MOON HOTEL, or at least a few mining camps for rare earths and things with high value, high enough to justify going to the MOON to get them.
And of course, an "interplanetary space port" hub. "Moon" becomes the new LAX [let's say].
It's my understanding that there's a LOT of Titanium on the moon. You could build long distance space ships with this. And structures. And if it's Titanium OXIDE, processing it would release OXYGEN.
But as for using 'Artemis' in the name, I think the answer is very simple: Artemis is kinda like Rosie the Riveter for Ancient Greece. And so it's (probably) just a symbol of putting the first WOMAN on the moon. Or it could mean more, maybe 'bold exploration' or similar.
[on a side note, according to Wikipedia, the Temple of Artemis at Ephesus was one of the 7 wonders of the ancient world]
