It sounds like we’re getting tantalizingly close! This isn’t just pie-in-the-sky stuff; we’re seeing real experiments and problem-solving happening. The biggest challenges seem to revolve around the moon’s unique environment: that pesky low gravity messing with bubble formation in some extraction methods, and the sheer abrasiveness of the regolith eating away at equipment. While Sierra Space is hoping to test their system on the moon by 2028 (fingers crossed!), it really depends on how quickly they can overcome these engineering hurdles. It’s not a question of “if” anymore, but “when” – and that’s super exciting! Imagine a future where we can build and fuel rockets directly from lunar resources. That would be a game-changer for space exploration.
