... ''' - 2000.53.82 '''Number of Pages''' - 7 Abstract The problem of defining a plan for protecting sophisticated electronic systems in severe space radiation environments is difficult and complex. It is important ... the environ- ment threatens the system and the alternative costs of the comprehensive application of protection measures, which may actually be unnecessary or excessive in many areas. Finally, a balance needs ...

Sunglasses that protect against UV light are essential for astronauts and protect against visible light, which can also damage the eye. Astronauts should never look directly at ... -sensitive area in the eye, the retina. In space there is no atmosphere to help protect us from some of the damaging effects of the Sun's energy. When astronauts spacewalk, however, they put on reflective visors to protect the eyes when they are working in direct sunlight. ---- Answer provided by Dr. Jonathan B ...

No, the spacesuit provides all the protection an astronaut needs. It protects from the extreme heat and cold of space and provides protection from the radiation in space. It provides the necessary cooling ...

... less focused it will be by the time it gets to the human. Active radiation protection takes the form of electromagnetic shielding, electrostatic shielding and chemical radioprotection. Electromagnetic shielding and electrostatic shielding use generated energy fields to deflect or reroute the radiation around the protected area or spacecraft. However these fields do not prevent GCR exposure. Chemical radioprotection uses specialized ...
