The Problem with Radiation in Space
When astronauts travel in space, they face a big danger: radiation. In space, there’s no atmosphere to protect them from harmful radiation from the sun and cosmic rays. This radiation can cause serious health problems, so scientists need to find ways to keep astronauts safe.
Current Radiation Protection
Right now, spacesuits and spacecraft use heavy materials to block radiation, but these materials can be uncomfortable and bulky. A new idea from the scientists at Ghett University is 3D-printed Hydrogels. Hydrogels are soft, flexible materials made mostly of water and polymers.
How 3D-Printed Hydrogels Works
Hydrogels work by absorbing radiation by trapping it inside the water, which stops it from reaching astronauts or equipment. 3D-printed hydrogels can also be shaped to fit the needs of space missions, due to their lightness and flexibility, making them easy to use.
Better Spacesuits
Hydrogels could make spacesuits lighter and more comfortable while still providing the necessary protection from radiation. This would be a major improvement over the bulky suits astronauts wear now, providing them with more freedom and comfort without sacrificing safety.
Protecting Spacecrafts
Hydrogels could also be used in a spacecraft to protect astronauts and sensitive equipment from radiation. By adding hydrogel shielding, spacecraft could become safer for long journeys, like missions to Mars, ensuring radiation doesn’t interfere with the mission or the crew’s health.
