Can A Mega-Magnetic Field Protect Astronauts From Radiation?
A bunch of people really, really want to go to the Red Planet on the proposed one-way Mars One trip; more than 1,000 applicants are being considered in Round 2 selections. They will face, however, more radiation during their journey that could put them at higher risk of cancers down the road. While the solution could be to add more shielding to a spacecraft, that’s both heavy and expensive.
Enter the alternative: a magnetic field. A group calling itself the EU Project Space Radiation Superconductive Shield says their technology will “solve the issue of radiation protection in three years” and is seeking academic collaborations to make that happen. Here’s how it will work:
“The SR2S superconducting shield will provide an intense magnetic field, 3,000 times stronger than the Earth’s magnetic field and will be confined around the space craft,” a press release states.
“The magnetic fields will extend to about 10 metres in diameter and ionizing particles will be deflected away. Only the most energetic particles will penetrate the superconducting shield, but these will contribute the least to the absorbed radiation dose as their flux is negligible. This will address the issue of suitability of people for space travel as it will open up eligibility for space travel regardless of gender.”
