The future of space travel might be sitting in your fish tank 🌱 You know that moss growing in your aquarium? Turns out it filters water, pumps out oxygen, and actually gets stronger when exposed to low doses of radiation. Researchers at the University of Naples Federico II tested it, with support from ESA Discovery and the results genuinely surprised them. If we’re ever going to keep astronauts alive on Mars, tiny, humble plants like this could be a big part of the answer. #DiscoveryPreparation 📹 @europeanspaceagency 🎞️ @gettyimages; @agrariaunina; ESA; ESA/ @nasa 📸 @uninait
