What is that research and testing laboratory orbiting in outer space? It’s the International Space Station (ISS)! With the help of vibrant images and factual, elementary-level STEM text translated into North American Spanish, this nonfiction astronomy title for children examines the history of the ISS, its construction, how it operates, and what it is used for. It also explores what life on board is like for the crew. A space science feature spotlights common types of ISS experiments. Captions, on-page definitions, and an index support readers in grade 2 and up.
