The courses are being offered online--it's a shame grad classes are too expensive to just take for fun! Looks like $6,800 or so to take one of the two they're offering next semester, or about $12,700 for both. The Masters degree would end up costing you about $58.7k plus $1,000/semester in fees. It's a hard sell for something that still looks relatively far in the future, but I suppose if space mining is truly is your dream career, it's great that this program exists.
