Robots in space

Robots don't need to breathe, eat, or sleep. This makes them perfectly suited for work in the vacuum of space. Rovers on Mars have given humanity a wealth of knowledge about this planet, and machines that repair shuttles and other equipment are invaluable to astronauts. In this exciting STEM exploration, readers learn about space robots. Intriguing sidebars explore the ways science fiction has influenced the creation of real robots, and informative fact boxes and accessible main text discuss robots of the past, present, and future. Full-color photographs and a list of critical-thinking questions keep readers engaged as they learn.
