You know that I love plants and astronomy. And I’m always interested when there’s new things going on: like NASA scientists testing how to grow vegetables and greens in the space. This specially designed greenhouse doesn’t only give you important nutrients but it also does air revitalization, water recycling or waste recycling.
The idea is actually quite simple: the astronauts breath (hopefully) which makes carbon dioxide. As it happens, plants use that to photosynthesize. And that process creates oxygen for the astronauts to breath with the awesome side products for them to eat. There’s a natural cycle. Or a a bioregenerative life support system, as they say in NASA. And LED-lights provide the needed light.
