Toxic dust on Mars would present serious hazard for astronauts
By Jack Guy, CNN
Published Mar 27, 2025
"Substances such as silica, gypsum, perchlorates and nanophase iron oxides contained in Martian dust could have life-threatening effects on members of a potential Mars mission, according to a study published in the journal GeoHealth last month.
"'The biggest danger is the risk to astronauts’ lungs. Since the dust is so fine, it is expected to remain in astronauts’ lungs and some of it will be absorbed into the bloodstream,' study co-author Justin Wang, a medical student at the Keck School of Medicine of the University of Southern California (USC), told CNN on Wednesday.
"'Astronauts are already at risk for pulmonary fibrosis due to the radiation exposure in spaceflight, and many of the hazards including silica and iron oxides can cause pulmonary disease that could be superimposed.'
"Wang also highlighted concerns that perchlorates – chemical compounds that have been detected at toxic levels in Martian soil – could cause thyroid dysfunction and aplastic anemia – a condition in which the body stops producing enough blood cells."

"None of the current space craft intended to ferry human beings back and forth to Mars are realistic fellow citizens.
And the problem is gravity.
Just imagine, because of the lack of gravity the occupants of the ISS must exercise for hours a day just to survive for a few months, and still return to Earth unable to walk.
A true interplanetary craft must create artificial gravity, and the only way we know to do that is via centrifugal force.
But the spaceships we see in movies, where there is some part that spins around another, are also unrealistic and unnecessary.
Unrealistic because such a craft would be unacceptably subject to mechanical failure, and unnecessary because all we need do is spin the entire ship.
However such a ship must be built in space, as the most simple and efficient shape is a wheel and could not be launched from Earth.
Think of it as a space station from a 1950s movie, tilted to the side with a rocket/ion engine in the center. The wheel would spin to create gravity as the engines propelled it towards its destination.
Primitive interplanetary travel can and must be accomplished now my friends.
But thus far we are pursuing a path destined for certain failure."

No.
Bigots stay here.
The last thing that the universe needs is racism, sexism, homophobia, climate change denial, flat planet, anti-vax, nuclear bomb apologia, slavery, etc, spreading out beyond Earth uncontrollably.
It's somehow "unstoppable" - now -; why make it worse?
@Anonomouse1981 Um, my point was that it would be a one-way mission that ends in...
