- Space junk is a big problem for astronauts. But there is plenty of litter and junk on earth too, especially floating around in our oceans. Think of a special robot you could invent to clean up the floating junk that is hurting our fish, whales, seals and other sea animals?
- The technology used on the space junk robot was inspired by the special sticky parts of a gecko’s foot. Think about your favorite animal and what they are really good at. Sense of smell? Running fast? What kind of new technology could be inspired by your animal’s special abilities?
