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 neighbour 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.

Can Astronaut Girl save the day with a little help from science? Find out as she and her space crew blast off on new adventures in this chapter book series! When Val's teacher gives her class a science assignment to build terrariums, Val can't wait to get started! She's picked Wallace and her two friends, Ling and Abby, to join her group, and she expects to be in charge...after all, she is Astronaut Girl! But Val soon discovers it's impossible for them to agree on anything. And things don't get much better when the group and the Astro Crew zoom off to Mars for an outer-space adventure. Can the group finally put their heads together in order to save themselves from a giant sandstorm, or will they be stranded on Mars forever? Exciting, easy-to-read books are the stepping stone a young reader needs to bridge the gap between being a beginner and being fluent.
