A number of well being issues each recognized and unknown await these foolhardy explorers who (God forbid) may try and breathe the mud of Mars. That’s a crude abstract of the findings of a brand new examine by researchers from the College of Colorado Boulder.
The examine, printed within the journal GeoHealth, is the primary to take a complete have a look at the chemical elements that make up Martian mud, and their potential impacts on human well being. It was undertaken by a staff from the worlds of medication, geology and aerospace engineering.
Lengthy-term publicity to Martian mud might result in persistent respiratory issues, thyroid illness and extra, in response to the findings.
“This isn’t essentially the most harmful half about going to Mars,” stated Justin Wang, lead writer of the examine and a pupil within the Keck Faculty of Drugs on the College of Southern California in Los Angeles. “However mud is a solvable downside, and it’s value placing within the effort to develop Mars-focused applied sciences for stopping these well being issues within the first place.”
Wang, a CU Boulder alumnus, famous that Apollo period astronauts skilled runny eyes and irritated throats after inhaling mud from the moon. Apollo 17’s Harrison Schmitt likened the signs to hay fever.
However scientists know so much much less concerning the potential harms of Martian mud. To start to reply that query, Wang and his colleagues drew on knowledge from rovers on Mars and even Martian meteorites to raised perceive what makes up the planet’s mud. The group found a “laundry checklist” of chemical compounds that may very well be harmful for folks—at the least when inhaled in massive portions and over lengthy durations of time.
They embrace minerals wealthy in silicates and iron oxides, metals like beryllium and arsenic and a very nasty class of compounds referred to as perchlorates.
In lots of circumstances, these elements are current in solely hint quantities in Mars mud. However the first human explorers on Mars could spend round a 12 months and a half on the floor, growing their publicity, stated examine co-author Brian Hynek.
“You’re going to get mud in your spacesuits, and also you’re going to need to take care of common mud storms,” stated Hynek, a geologist on the Laboratory for Atmospheric and Area Physics (LASP) at CU Boulder. “We actually must characterize this mud in order that we all know what the hazards are.”
Into the bloodstream
One factor is obvious, he added: Mars is a dusty place.
A lot of the planet is roofed in a thick layer of mud wealthy in tiny particles of iron, which provides the planet its well-known purple colour. Swirling mud storms are frequent and, in some circumstances, can engulf your complete globe.
“We expect there may very well be 10 meters of mud sitting on prime of the larger volcanoes,” stated Hynek, a professor within the Division of Geological Sciences. “Should you tried to land a spacecraft there, you’re going to only sink into the mud.”
Wang discovered his personal option to Martian mud via a singular educational path. He began medical faculty after incomes bachelor’s levels from CU Boulder in astronomy and molecular, mobile and developmental biology, adopted by a grasp’s diploma in aerospace engineering sciences. He at present serves within the Navy via its Well being Professions Scholarship Program.
He famous that the most important downside with Martian mud comes right down to its measurement. Estimates recommend that the common measurement of mud grains on Mars could also be as little as 3 micrometers throughout, or roughly one-ten-thousandth of an inch.
“That’s smaller than what the mucus in our lungs can expel,” Wang stated. “So after we inhale Martian mud, a number of it might stay in our lungs and be absorbed into our blood stream.”
An oz. of prevention
Within the present examine, Wang and a number of other of his fellow medical college students at USC scoured analysis papers to unearth the potential toxicological results of the elements in Martian mud.
A few of what they discovered resembled frequent well being issues on Earth. Mud on Mars, for instance, accommodates massive quantities of the compound silica, which is plentiful in minerals on our personal planet. Individuals who inhale a number of silica, equivalent to glass blowers, can develop a situation referred to as silicosis. Their lung tissue turns into scarred, making it onerous to breath—signs much like the “black lung” illness that coal miners typically contract. Presently, there isn’t any treatment for silicosis.
In different circumstances, the potential well being penalties are a lot much less well-known.
Martian mud carries massive portions of extremely oxidizing compounds referred to as perchlorates, that are made up of 1 chlorine and a number of oxygen atoms. Perchlorates are uncommon on Earth, however some proof means that they will intervene with human thyroid operate, resulting in extreme anemia. Even inhaling a number of milligrams of perchlorates in Martian mud may very well be harmful for astronauts.
Wang famous that the very best time to organize for the well being dangers of Martian mud is earlier than people ever make it to the planet. Iodine dietary supplements, for instance, would enhance astronauts’ thyroid operate, doubtlessly counteracting the toll of perchlorates—though taking an excessive amount of iodine can even, paradoxically, result in thyroid illness. Filters particularly designed to display out Martian mud might additionally assist to maintain the air in dwelling areas clear.
“Prevention is essential. We inform everybody to go see their major care supplier to test your ldl cholesterol earlier than it offers you a coronary heart assault,” Wang stated. “The most effective factor we are able to do on Mars is make sure that the astronauts aren’t uncovered to mud within the first place.”
Co-authors of the present examine embrace USC medical college students Jeremy Rosenbaum, Ajay Prasad and Robert Raad; Esther Putnam, former graduate pupil in aerospace engineering sciences at CU Boulder now at SpaceX; Andrea Harrington on the NASA Johnson Area Middle; and Haig Aintablian, director of the Area Drugs Program on the College of California, Los Angeles, additionally affiliated with SpaceX.
