Mission to Mars May Warp Astronauts Brains" by Nsikan Akpan One day, space explorers might stroll along the red rocks of Mars. But radiation exposure during the trip may wipe away their memories of home. A new report says that cosmic rays can change the physical architecture of the mind’s nerves, harming the brain regions that govern memory. Cosmic rays, comprised of high-speed atomic particles, blanket the Milky Way galaxy. The radiation constantly bombards our planet, but the Earth’s magnetic field and its atmosphere save us from the most dangerous rays. People who venture into deep space aren’t so lucky, as cosmic rays can easily penetrate a spaceship’s metallic hull or a space helmet. So before NASA sends anyone into deep space, they want to figure out the possible long-term ramifications of exposure to cosmic radiation. One item of concern is radiation-induced memory loss, says cancer researcher Charles Limoli of the University of California Irvine, who led the report published May 1 in Science Advances. Cancer radiotherapy can impair human memory and spawn dementia, which is what drew Limoli’s team to the research. “Upon penetrating the body, these charged particles leave tracks of damage on the same scale as neurons,” Limoli said. “So we reasoned that [cosmic] irradiation might elicit long lasting structural changes in neurons that would lead to cognitive impairment.” © NewsHour Productions LLC.

The correct response is:

"Unlike the first excerpt, the goal of the author of the second excerpt is to offer a solution to a significant issue."

The first excerpt focuses on the potential risks associated with cosmic radiation and its impact on memory for astronauts traveling to Mars, highlighting the need for further research. In contrast, the second excerpt discusses the sensory experiences of astronauts in space and how NASA addresses food preferences, indicating a solution-oriented approach to improve astronauts' quality of life while in orbit.
