Description One of the main advantages of drones is that they can be used in situations that are too dangerous for humans. Space is probably the most dangerous environment where men and women work, so it's only natural to use drones for space exploration. This far-out volume looks at the different kinds of drones used to explore other planets over the years, as well as new technology being developed for the future. This high-interest STEM topic is presented with age-appropriate text and supported by full-color photographs, sidebars and graphic organizers.
