Shields up: New ideas might make active shielding viable
Active shielding was first proposed in the '60s. We’re finally close to making it work.
In October 2002, ESA appointed a group of experts from CERN and other European institutes to revisit the issue of radiation shielding on deep space missions. Battiston assembled a new team, roughly based on the one responsible for building the AMS-02 superconducting magnet, and went to work to reassess the issue and propose some preliminary designs. The cooling problem was solved by using yttrium barium copper oxide, the first of the ReBCO family of superconducting materials that worked above the boiling point of liquid nitrogen.
