Explorarea spatiala serveste exclusiv intereselor "stiintei", asta se vede cu ochiul liber ... problema lor este acum sa descopere cum anume pot trece (in viata), prin centurile Van Allen.

Se pare ca nu, altfel nu ai ridica probleme aiurea.
"Humans have been affected by Belt particles,
though not as severly as some people might believe. Space Shuttle and Space Station astronauts inside their crafts receive about 2? mRems of additional dosage each time they pass through the SAA. Over the course of a week, this adds up to 7 x 30 = 210 mRems which is just below the dosage you get at ground-level in a single year (about 350mRem). Apollo astronauts, however, were forced to traverse the most intense regions of the Belts in their journey to the Moon. Fortunately,
the travel time was only about 30 minutes so their exposures were not much more than the total dose received by Space Shuttle astronauts (TBD).
This fact counters some modern speculations that the moonlandings were a hoax because astronauts would have instantly died as they made the travel through the belts. They may have experienced minor radiation poisoning if they had been in their spacesuits on a spacewalk, but no spacewalk was ever scheduled for these very reasons.
The shielding provided by the Apollo space capsule walls was more than enough to shield the astronauts from all but the most energetic, and rare, particles. Still, the astronauts reported seeing 'shooting stars' (TBD?). These were caused by very energetic particles streaking through the fluid in the eye and leaving behind a luminous, but fleeting, trail of light. Similar streaks have ben reported by astronauts in the Space Shuttle and other near-earth missions during solar storms. It is not known what the long-term consequences of these kinds of brief exposures are upon astronauts, but prospective travelers to Mars will no doubt see many more of them!"
