Space is full of potentially dangerous radiation. Here on Earth, our atmosphere and magnetic field protect us from the worst of it.
Astronauts on a deep-space mission would need other forms of protection. In collaboration with National Chemistry Week, this Reactions video is all about chemistry in space.
