the lives of astronauts returning to earth by 510 or 15 years that the change that the actual queen chandni. civil yaml that a problem here if we wanted to tackle the problem of high energy cosmic rays mechanically we were unfortunately need 3 to 4 metres of absorbent material such as water this is of course absolutely out of the question it would be far too heavy for use in a spaceship but it's that i mean that that's so that's without it. this space radiation superconducting shield or s r 2 s. project maybe halfway towards finding a workable solution to the problem. it's idea in itself a simple a force field generated around the spacecraft deflects the rate is similar to the earth's magnetic shield but it's as simple as the idea is putting it into practice is highly complex it requires an extremely powerful yet lightweight super conducting magnets that work efficiently at temperatures of just above absolute 0. at cern the european organization for nuclear research you to rossi and his team may have found the ideal material magnesium dipole ride. called the said miller superconductivity is
