if we can recycle on earth why can't we recycle in space? astronauts need to recycle as much as they can if they want to survive on mars. so wouldn't it be cool if you could take some of the materials the astronauts aren't using and recycle them to build 3-d printed habitats where astronauts can live and work? pretty cool right? we want your help
to make this dream a reality. help us turn this... into this... and we'll turn your idea...
how can 3d printing help humans,into this. think you can solve this challenge? show nasa centennial challenges you've got what it takes and help us take the next giant leap in space recycling.
