Even though we haven't been to Mars yet, humans are thinking about how we would live there
Space agencies like NASA are thinking about how we could build homes on another planet with different supplies and very very far from Earth.
- Could we blow them up like an beach ball?
- Could we use a 3D printer?
- Could we build them with supplies there (like the picture shows)?
NASA also does experiments where people pretend to live and work on Mars. This way they learn what humans need to feel at home.
