And that is all it is. There has been billons of dollars spent on the ISS to house a few astronauts in low earth orbit. Think moon rocks. The total weight of all the moon rocks is less the 100 lbs. The idea we will mine comets or asteroids or some other planet or moon is so far away ...
I beg to differ:
During the six Apollo landing missions, 2,415 samples weighing 380.96 kilograms (839.87 lb) were collected.
