I made a sleep mask/cosmic ray shield. The sleep mask helps ISS crew stay asleep by keeping out light. The cosmic ray shield helps ISS crews’ eyes stay safe by blocking fast fast FAST protons (cosmic rays)!
I saw pictures of ISS crew wearing sleep masks. They block light so crew can sleep. I learned that ISS crew saw flashes when their eyes were open or closed. Charles Duke wore the ALFMED and found that the flashes are cosmic rays. Sheila Thibeault said hydrogen is a good shielding for blocking cosmic rays. ABS plastic has lots of hydrogen. So I made a sleep mask that has lots of ABS in the front. My design helps ISS crew stay asleep and keeps their eyes safe from cosmic rays.
