Mitigation of the Spacecraft Radiation Environment via Magnetic Shielding by an Array of Dispersed Superconducting Magnets (NCC958PF04305)
Principal Investigator
Research Area:
Radiation health

Spacecraft are self-contained biospheres that must be designed to protect astronauts from harmful aspects of the interplanetary environment. Radiation encountered in deep space poses a significant threat to the health of astronauts and the success of future NASA missions beyond low-Earth orbit. Isotropic galactic cosmic rays (GCRs) and intermittent solar particle events (SPEs) threaten to cause acute radiation sickness and exceed NASA's permissible exposure limits for cancer risk for explorers in near-term space operations. Thus, effective methods of mitigating this radiation risk are high priorities for long-duration space flight. This experiment proposed to design a magnetic shielding architecture capable of reducing the amount of radiation by a factor of four to alleviate many biological uncertainties associated with this risk in the astronaut habitat. Through computational modeling, the spectra of harmful radiation was investigated and lead to the design of a “swarm-bot” type magnetic field configuration that deflected incoming radiation, thus forming a “safe-region” within the astronaut habitat. The novel method proposed here will work in concert with many aspects of existing superconductor technology. This system operates in parallel with the existing NASA Orion spacecraft infrastructure and in a continuous mode but without the need for continuous power.
