Sneaky dust raises new questions about the future of human exploration of Mars”: Astronauts' brains are half made of Martian dust. "Minor particles of Martian dust can penetrate deep into the lungs, enter the bloodstream and potentially reach the brain. The particles were detected using the PIXL instrument aboard the Persistence rover. He analyzed dust that settled on samples of materials, including those used to make space suits. Particles were only 100-200 times the size. thickness of a human hair. On Earth, ultrafine particles are able to penetrate from the nasal cavity into the brain via the olfactory nerve. In addition, particles smaller than 2.5 micrometers can reach deep into the lungs and enter the bloodstream. However, the direct effect of Martian dust on the human body has not yet been studied."
