Mars has life-supporting molecules but its dust is lethal—Know why
What's the story
A recent study has revealed that the presence of toxic dust on Mars could complicate future manned missions to the planet.
The research highlights potential health risks associated with Martian dust and suggests necessary personal protective equipment for astronauts.
This finding is particularly significant as it draws parallels with the Apollo Moon missions, where astronauts experienced health issues due to lunar dust exposure.
The research comes days after a NASA rover detected largest organic compounds ever on the Red Planet.
Health risks
Martian dust: A potential health hazard
During the Apollo missions, astronauts were exposed to lunar dust which stuck to their spacesuits and entered the lunar landers.
The exposure caused symptoms like coughing, runny eyes, and irritated throats. Prolonged exposure had chronic health effects.
Although Martian dust isn't as sharp or abrasive as lunar dust, it has a similar tendency to stick to surfaces.
Dust composition
Martian dust particles can penetrate into lungs and enter bloodstream
The fine particles of Martian dust, about 4% the width of a human hair, can penetrate deep into lungs and enter bloodstream.
The dust contains toxic substances like silica, gypsum, and various metals.
As the researchers wrote in GeoHealth journal, "A mission to Mars does not have the luxury of rapid return to Earth for treatment."
Communication delay
Challenges in remote medical support
The study also notes that a 40-minute communication delay between Mars and Earth could restrict the effectiveness of remote medical support from Earth.
This highlights the need for astronauts to be properly prepared for the health risks posed by Martian dust exposure.
The researchers stress on limiting exposure to dust as a critical step in preparing for manned missions to Mars.
