Journey from the deepest trenches in the oceans to the farthest humans have ventured into space and learn what it takes to explore the extremes. You might just be surprised by how similar the domains of ASTRONAUTS and AQUANAUTS really are.

Space and the ocean. If you don't think they go together, think again! Both deep-sea and space explorers have to worry about pressure, temperature, climate, and most importantly, how to survive in a remote and hostile environment. Join us on an amazing journey as we go up in space with astronauts and dive deep down in the ocean with aquanauts to explore the far-off places of our planet and the solar system.

With a strong tie into STEM topics--such as making connections, making comparisons, and recognizing patterns across content areas--readers will discover the amazing science and incredible innovations that allow humans (and sometimes only machines) to survive in these harsh environments.
