Look, no one said building a large harvester to roam around the Moon and sift through hundreds of tons of regolith to retrieve small amounts of helium-3 would be easy. And that’s to say nothing of the enormous challenge of processing and then launching any of this material from the lunar surface before finally landing it safely on Earth.
If we’re being completely honest, doing all of this commercially is a pretty darn difficult row to hoe. Many commercial space experts dismiss it out of hand. So that’s why it’s gratifying to see that a company that is proposing to do this, Interlune, is taking some modest steps toward this goal.
Moreover, recent changes in the tides of space policy may also put some wind in the sails of Interlune and its considerable ambitions.
