NSN Short | Cosmic Ray Danger - NOVA Vodcast | PBS

What this episode covers

Cosmic rays are inescapable in space. They can rip right through an astronaut, damaging DNA and possibly causing cancer and memory loss over the long-term. But recent research shows that antioxidants, found in certain berries and fruit, may decrease the effects of this type of radiation. For more, watch "Can We Make It To Mars?" on pbs.org/nova.
