The Advanced Radiation Protection project element assesses and matures disruptive technologies that show the potential to improve our capability to protect astronauts from the harmful effects of space radiation during deep space missions.
The Advanced Radiation Protection element assesses and matures disruptive technologies that show the potential to improve our capability to protect astronauts from the harmful effects of space radiation during deep space missions. The Thick GCR Shielding activity focuses on validating an optimal shield thickness for Galactic Cosmic Ray (GCR) mitigation and quantifying the uncertainty associated with space radiation transport calculations used in astronaut risk estimation. Thick target charged particle beam measurements and transport code benchmarks will be used to validate an optimal shield thickness and quantify transport uncertainty for a variety of spacecraft materials. A probabilistic propagation of uncertainty in particle fluence from thick shield transport results to astronaut exposure (effective dose and risk) in space vehicles will also be performed. The results of this effort will enable the design of minimal mass exploration vehicles for which astronaut radiation risk is as low as reasonably achievable.

By the time it’s fully awake in about 20 months, the team at NASA’s Goddard Space Flight Center in Greenbelt, Md., charged with researching and tracking solar activity, will have at their disposal a […]
