Mars Rover Finds Ultrafine Dust on Spacesuit Materials That Can Reach the Lungs and Bloodstream

Summary

NASA's Perseverance Mars rover measured fine and ultrafine Martian dust particles clinging to samples of spacesuit materials carried aboard the rover, over 1,645 Martian days. Some of the particles are small enough to penetrate the lungs and enter the bloodstream. The findings are published in the Proceedings of the National Academy of Sciences. According to the reporting, the results could inform spacesuit and habitat design, dust-removal procedures and crew health standards for future NASA missions to Mars.
