Val, aka Astronaut Girl, is just your typical eight-year-old scientist. She has her own laboratory and conducts experiments with her crew--her cat and baby brother. She loves science and knows everything about outer space. That's why she's surprised to learn that her new neighbor Wallace would rather talk about a fake space show than about real missions. But when Astronaut Girl, Wallace, and the Astro crew get lost on their own lunar adventure, they must all work together to find their way back home.
