Honestly, it’s a mixed bag. We’ve nailed the science of extracting oxygen and metals – we know how to do it. The real question is whether we can make it work reliably and affordably on the moon. Think of it like baking a cake: we have the recipe (the science), but doing it in a wonky oven (the lunar environment) with limited ingredients (regolith quirks) makes it much trickier!

That low gravity thing is a real head-scratcher for some methods, and that dust… ugh, it gets everywhere and breaks everything. But hey, that’s what engineers are for, right?

As for when we’ll see this actually happening… 2028 for Sierra Space’s test is ambitious. Space stuff always takes longer (and costs more) than you think. But the fact that companies and universities are seriously investing in this gives me hope. If we can crack this resource extraction nut, the moon becomes so much more than just a place to plant a flag – it becomes a launching pad for deeper space exploration. And that’s worth getting excited about!
