Gavin is an eight-year-old astronaut with a red suit and a special gravity power. Alongside Denny, Bark and Cloud, he takes young explorers from Earth to Mercury and beyond. Children can follow the adventures, while parents, carers and educators can explore the science notes and try the activities together.
