The Dangers of Space Radiation

Sending men to the Moon and bringing them back safely is held to be the greatest technical achievement of the 20th Century.

Ellen Stofan CC BY 2.0“NASA’s focus now is on sending humans beyond low-Earth orbit to Mars… We are trying to develop the technologies to get there, it is actually a huge technological challenge. There are a couple of really big issues. For one thing – Radiation. Once you get outside the Earth’s magnetic field we are going to be exposing the astronauts to not just radiation coming from the Sun, but also to cosmic radiation. That's a higher dose than we think humans right now should really get.”

“Radiation surely must be the biggest showstopper preventing mankind’s exploration of the Universe.”

Clive Dyer has worked in space and radiation research for more than 40 years, authoring more than 200 publications in the field

In a significant speech delivered in Washington on 26 March 2002 NASA administrator Sean O'Keefe told his audience of aerospace professionals that NASA faced two key technical obstacles in the exploration of space, the most significant being:

The hazardous radiation environment for humans travelling beyond Earth.

Figure 2"How do we shield astronauts from radiation on longer missions? ... How do we supply spacecraft with energy needed for these far-reaching journeys?

These are questions that we can answer and will answer. And these are the questions whose answers no doubt will reap untold benefits right here on Earth."
