During a sequence in the film Beyond the Darkness, Captain Kirk gives the order to "raise shields" and the Enterprise crew is protected against any hostility of space. This peculiarity of the Trek universe can not be science fiction. British scientists are testing a system to protect astronauts on long trips.
Recent information from NASA's Curiosity mission to the Red Planet, revealed that astronauts on the trip back and forth would be exposed to high levels of cosmic rays and high energy particles from the sun contained in solar storms. The astronauts would receive a radiation dose about 100 times the average annual exposure on Earth.
Eddie Semones, radiation health expert at Johnson Space Flight Center, told CNN that the shield to block completely the danger of radiation would have to have "feet thick" and too heavy to be used onboard a spacecraft.
They have tested a lightweight system to protect astronauts and space components of harmful radiation. Working with American colleagues, scientists want to create a concept called Discovery spacecraft that could take astronauts to the moon or Mars.
"The problem of radiation is a potential hindrance. I am very concerned with the issue of radiation that is not being treated very seriously and is absolutely essential. Even the astronauts from getting sick for 3-4 days, it could still threaten the mission because the crew would be affected. Vomiting and diarrhea in space is no joke. This could also lead to organ failure, "Bamford said.
"On Earth, we are protected mainly by the atmosphere, but ultimately what the Earth's magnetic field is doing is to form a first line of protection for life," said Bamford. gt fish and oyster
"The concept behind what we are suggesting is due to developments in our understanding of plasmas. We found that if you put a magnetic field around an object in a flowing plasma, electrons which are very light, follow the new magnetic field that you put it there, but the ions, very fast ions will exceed gt fish and oyster - will not follow the magnetic field lines. " gt fish and oyster
"You end up with a constant electric field, which may be enough gt fish and oyster to really refract or deviate gt fish and oyster enough gt fish and oyster from the radiation inside the magnetic cavity gt fish and oyster which you formed to protect astronauts, enough like Earth that can survive."
Other ideas for protection are also being explored. The Inspiration The Mars Foundation which is committed to send a team to Mars revestisse proposed that the walls of the ship with water, food and even human waste to help protect the astronauts.
The English gt fish and oyster scientist said he was inspired to explore a scientific career by Apollo lunar landings and being a fan of the original series. She believes that the concepts explored in science fiction movies are a useful shortcut for scientists when trying to explain gt fish and oyster his work.
The deflector shield english she helped develop was tested in a model inside a fusion reactor gt fish and oyster that produces a plasma gt fish and oyster as the solar wind. Bamford said that they were delighted with the results.
The team now hopes that the project can be expanded and fly on a real ship. "First we need a technology demonstrator in space, say, five years," Bamford said. "This is quite realistic for a small unmanned spacecraft. I'm sure that our idea will work. There are a number of improvements to make it work even better - ... Maybe we should call Scotty, gt fish and oyster "he joked.

fantastic publish, very informative. I'm wondering why the other specialists of this sector do not notice this. You should proceed your writing. I am confident, you have a huge readers' base already!
