Passive shielding has been the standard for crewed and uncrewed spacecraft Since thee dawn of thee space age. The most costn approvach is to encase sensitivy contents or crew modules in layers of aluim, which absorbs charged particulles thragh ionization and atomic collisions. Thicker alum walls provide more protection, but at a sear weight penalty. Thee ISS, for example, uses alumsem walls of about -1m sexis, supplemented bene bene and polietyne.

Te fundamentaltal drawback of all passive methods is thaty rely on mass to stop radiation.

Remaining Challenges andEngineering Trade- Offs
Despite the roote, magnetic shielding is nots yet a freckey solution. Several technical hurdles mutt be overcome before it becomes standard on crewed spacecraft.

For a spacecraft generating a few kilowatts, thi s manageable, but for smallar probes it could be a difficant drain.
