From Radiation to Isolation: 5 Big Risks for Mars Astronauts (Videos)

Even astronauts who live on the International Space Station, which sits inside Earth’s protective magnetic field, are exposed to 10 times the radiation they would if they were back on Earth, NASA officials said in a statement and series of videos from the agency’s Human Research Program.

Anyone who traveled through deep space would be at much greater risk from radiation exposure. Outside of Earth’s protective shield, radiation can increase cancer risk and damage a person’s central nervous system (which would cause altered cognitive function, reduced motor function and behavioral changes), NASA’s Human Research Program said. Other dangers of being exposed to such high radiation include nausea, vomiting, anorexia, fatigue, cataracts, cardiac disease and circulatory disease. …….https://www.space.com/42918-big-space-risks-mars-astronauts-videos.html

Space travel enthusiasts show their ignorance of ecology and the dangers of Plutonium 238

I do not have time at the moment to really think about this one, –  But –  a couple of  lovely sentences just leaped out at me:

Plutonium-238 is very special for the fact that it’s a material that poses virtually no danger to anyone unless you do something insane 

we have to put our illogical fears aside 

That’s from this absolute hymn to Plutonium 238  – Forbes 13 Dec 18 – NASA Doesn’t Have Enough Nuclear Fuel For Its Deep Space Missions
