Meet NASA inventor Anthony Longman! He's here to introduce readers to the expandable space habitat, an expanding home for astronauts to live in while exploring space. Alongside of Anthony, readers will learn about how he and his team are designing the habitat using tensegrity. They'll also be introduced to such space concepts as orbits, lunar cycles, asteroids, radiation, and more. Students will learn about the process of technological design and the importance of space exploration. The Inventor Challenge at the back of the book encourages readers to create their own inventions.
