註釋Meet NASA inventor Marco Pavone! He's here to introduce readers to leaping lowgravity rovers. Alongside Marco, readers will learn about the need for jumping rovers and the importance of studying small solar system bodies like asteroids and comets. They'll explore such concepts as gravity and internal actuation to understand how the rovers are designed to jump and move. The Inventor Challenge at the back of the book encourages readers to create their own inventions.
