Sting Posted April 19, 2007 Report Share Posted April 19, 2007 http://news.bbc.co.uk/2/hi/science/nature/6567709.stm British scientists are planning to see whether a Star Trek-style deflector shield could be built to protect astronauts from radiation. They argue that magnetic shields could be deployed around spacecraft and on the surfaces of planets to deflect harmful energised particles. Quote We must all fear evil men.

De1Rekt0n Posted April 19, 2007 Report Share Posted April 19, 2007 (edited) Ovo je odlicna tema da malo porazgovaramo o Van Alenovim poljima i da li covek stvarno moze da ih prezivi, aludiram na putovanje na mesec za koji neki smatraju da je pravljeno u Holivudu. Onda ide i vecito pitanje kako Rusi koji su imali 5x vise vremena u svemiru nisu uspeli da posalju coveka izvan orbite a ne do meseca? http://en.wikipedia.org/wiki/Van_Allen_radiation_belt Edited April 19, 2007 by De1 Quote Link to comment Share on other sites More sharing options...
dzontra.volta Posted April 19, 2007 Report Share Posted April 19, 2007 James Van Allen himself, now deceased (August 9, 2006), dismissed these ideas. In practice, Apollo astronauts who traveled to the moon spent very little time in the belts and would have received a harmless dose [6]. Nevertheless NASA said that they deliberately timed Apollo launches, and used lunar transfer orbits that only skirted the edge of the belt over the equator to minimize the radiation. Astronauts who visited the moon would probably have a slightly higher risk of cancer during their lifetimes. Quote Link to comment Share on other sites More sharing options...
