Yeah, moss on the ISS is like the space version of a sidewalk garden. They’re tough, but lunar dust is a different beast – no water, vacuum, extreme temperature swings. If we grow the right crops with hydroponics or aeroponics, plants could scrub CO₂ and maybe even feed the crew, but the tech for a truly “real‑time” life‑support loop on the Moon would need robust dust‑sealing, radiation shielding, and a closed‑loop nutrient system. In short, it’s doable with the right engineering, but it’s still a hard problem that’ll keep us busy for a while.
