Astronauts, Clean Up Your Outer Space!

1.  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?
2. 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?
