Radiation for Dummies

Meet Helga and Zohar, the dummies destined for a pioneering lunar flyby to help protect space travelers from cosmic rays and energetic solar storms.

Do Astronauts Need Sunscreen? (video)

Space is full of potentially dangerous radiation. Here on Earth, our atmosphere and magnetic field protect us from the worst of it.

Planning a trip to Mars? You'll want to remember your anti-radiation pills.

Scientists at The Australian National University (ANU) have designed a new nano material that can reflect or transmit light on demand with temperature control, opening the door to technology that protects astronauts in space from harmful radiation.

NASA Studies Simulated Radiation

In each life a little rain must fall, but in space, one of the biggest risks to astronauts' health is radiation "rain".

Will astronauts traveling to Mars remember much of it? That's the question concerning University of California, Irvine scientists probing a phenomenon called "space brain."

Members of the successful Apollo space program are experiencing higher rates of cardiovascular problems that are thought to be caused by their exposure to deep space radiation, according to a Florida State University researcher.

Analysis of data from the MATROSHKA experiment, the first comprehensive measurements of long-term exposure of astronauts to cosmic radiation, has now been completed.

Two donuts of seething radiation that surround Earth, called the Van Allen radiation belts, have been found to contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth.

Humans have long dreamed of traveling to Mars, hopscotching across the solar system and fanning out into the cosmos beyond.

Astronauts floating weightlessly in the International Space Station may appear carefree, but years of research have shown that microgravity causes changes to the human body.

As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation - which would bombard astronauts on deep space missions to places like Mars - could accelerate the onset of Alzheimer's disease.

When Curiosity enters the Martian atmosphere on August 6th, setting in motion "the seven minutes of terror" that people around the world have anticipated since launch a year ago, the intrepid rover will actually be performing the mission's second daredevil stunt.

With the impending solar maximum expected to bring heightened rates of flares and coronal mass ejections (CMEs), putting at risk an ever-increasing human presence in space, Oh et al. designed and assessed a prediction system to keep astronauts safe from these solar storms.
