Radiation Barrier
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.
Water Shield
Dense and hydrogen-rich, water is an excellent radiation shield. By integrating it into hydrogels, astronauts could stay protected without bulky, leak-prone systems.

Flashing Eyes
Astronauts report eerie flashes caused by radiation particles interacting with the fluids in their eyes and brains. Hydrogels could minimize this unsettling exposure.

Martian Problem
Mars-bound astronauts could receive career-limit radiation doses in one mission. Hydrogels may become a critical tool for long-term survival in deep space.

Absorbing Innovation
SAPs can absorb 100x their weight in water, making them efficient and leak-resistant. Think of them as radiation-blocking "monster toys" for astronauts.
Future Shielding
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.
