Traveling more than 17,000 miles per hour in constant orbit around Earth, astronauts live and work aboard the International Space Station (ISS). Despite the hostile environment of space, the ISS has suitable living conditions for its workers. Astronauts breathe clean air, eat shrimp cocktail, exercise daily, take baths, and take out the trash—in zero gravity, of course. Floating around the ISS, the astronauts have important jobs, conducting experiments and doing research projects. Author Henry M. Holden explores the base camp to the universe from its design and construction to the amazing astronauts who work there.
