Giant Moon Blanket Could Protect Astronauts


Solar flares and powerful cosmic rays can shred DNA and increase cancer risks for future astronauts who might make long-term stays on future moon missions.
As NASA considers this issue in its plans for a return the moon by 2020, a team of college students has proposed a solution: giant blankets.
Engineering students at North Carolina State University (NCSU) designed a "lunar texshield," a layered blanket made of lightweight polymer material. The outer surface of the shield is a flexible array of solar cells that generate electricity. Underneath, a layer of radiation shielding deflects or absorbs incoming particles, to better protect astronauts in lunar outposts.
The students entered their design in a NASA-sponsored aerospace engineering competition for college students that will begin in June.
