Astronauts [EPUB ebook] 
A Space Discovery Guide

Supporto

Did you know that astronauts work on Earth and in space to study places beyond our planet’s atmosphere? But there’s a lot more to space travel than just research. With no gravity, a wild schedule that includes sixteen sunrises and sixteen sunsets every twenty-four hours, and no fresh food, it can be a challenge to stay healthy in orbit. Public and private space agencies are working to solve these problems as humans travel farther and more frequently into the depths of space. Learn more about the daily lives of astronauts and how they live, work, and prepare for the future in space.
