Space radiation, from solar storms to ancient supernovae, threatens both astronauts and gear. Hydrogels may soon offer portable, water-filled protection for deep-space missions.
Dense and hydrogen-rich, water is an excellent radiation shield. By integrating it into hydrogels, astronauts could stay protected without bulky, leak-prone systems.

SAPs can absorb 100x their weight in water, making them efficient and leak-resistant. Think of them as radiation-blocking "monster toys" for astronauts.
Though the radiation problem is far from solved, hydrogels could become a game-changing feature on future missions to Mars and beyond, protecting both humans and tech.
