Mars dust could pose a health risk to humans

A new study has revealed that Mars dust could be dangerous for people exploring the red planet. The Guardian reports that the study reveals a number of health risks and discusses the personal protective equipment that astronauts may need.

During the Apollo missions to the Moon, astronauts were exposed to lunar dust. The dust clung to spacesuits and seeped into the landing gear, causing coughing, watery eyes, and throat irritation. Studies have shown that prolonged exposure can lead to chronic health problems.

Mars dust, while not as sharp and abrasive as lunar dust, also sticks to everything. Its tiny particles, about 4% the thickness of a human hair, can penetrate deep into the lungs and enter the bloodstream. The dust contains toxic substances such as silica, gypsum, and various metals.

“A Mars mission is deprived of the opportunity to return to Earth and receive treatment quickly,” the researchers note in the journal GeoHealth. The 40-minute communication delay limits the effectiveness of remote medical assistance from Earth. Therefore, scientists emphasize the importance of reducing exposure to dust, which requires air filters, self-cleaning spacesuits, and electrostatic repulsion equipment.
