Living in space can be a dangerous business. Microgravity, vacuum, extreme hot and cold temperatures, lack of air and micro-meteorite impacts are just some of the problems that astronauts face as they struggle to survive outside the Earth's atmosphere.

In this topic, students learn about the perils of space, how to combat them, how to live in space with the help of spacecraft and how to deal with the new problems created by long-term life in space, on the International Space Station or on a trip of Mars.
