Magnetic Shield For Spacefarers

Future astronauts could benefit from a magnetic "umbrella" that deflects harmful space radiation around their crew capsule, scientists say.
The super-fast charged particles that stream away from the Sun pose a significant threat to any long-duration mission, such as to the Moon or Mars.
But the research team says a spaceship equipped with a magnetic field generator could protect its occupants.
Lab tests are reported in the journal Plasma Physics and Controlled Fusion.
The approach mimics the protective field that envelops the Earth, known as the magnetosphere.
