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. For a spacecraft bound for Mars, thee required shielding squuxness would add textands on kilograms, severely reducing payload capacity andd preventing launch costs.

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.
