Meet NASA inventor Robert Youngquist! He's here to introduce readers to solarsurfing space probes. Alongside Robert, readers will learn about heatresistant coating used on solar probes. They'll explore technology and concepts that Robert and his team draw on when designing the probes, including conduction, convection, radiation, solar energy, active thermal control, and solar white. The Inventor Challenge at the back of the book encourages readers to create their own inventions.
