Kinda getting the idea we’re not meant to leave this little blue marble.

When they return from Mars get Fauci to clean their boots.

Doesn’t sound any worse than Gary Indiana in the 70’s.

Just pick up some cheap Covid era masks at Harbor Freight to wear when they go outside for the fresh air.

"Martian particles have remained sharp and irregular, making them perfect for penetrating sensitive tissues."

I can see sharp, angular and irregular particles on the moon, but Mars has very high winds that must kick up the dust and erode the particles. Of course, the Mars atmospheric density is low and perhaps it doesn't have the power to kick up dust. Mr. Grok confirms that:

Wind Erosion and Aeolian Processes: Mars has an active aeolian (wind-driven) environment, with frequent dust storms, wind gusts, and sand movement. These processes cause particles to collide, abrade, and erode each other. When dust or sand grains are transported by wind, they undergo mechanical weathering—think of it like sandpaper grinding down sharp edges. Over time, this can smooth out angular particles, making them more rounded.

Martian Dust Characteristics: Martian dust is primarily composed of fine particles, often basaltic in origin, with sizes ranging from a few micrometers to tens of micrometers. Freshly formed dust (e.g., from volcanic activity, impacts, or frost weathering) tends to be angular and sharp due to its crystalline structure or fracturing processes. However, as these particles are swept up in wind events, repeated collisions and abrasion can chip away at sharp edges, reducing angularity.

Factors Influencing Rounding:
Particle Size: Smaller dust particles are more likely to be carried in suspension during storms, leading to frequent collisions that promote rounding. Larger grains (like sand) may saltate (bounce along the surface), which also causes abrasion but at a different rate.

Wind Intensity: Stronger winds, common during global dust storms, increase particle interactions, accelerating the smoothing process.

Composition: Martian dust often contains minerals like olivine, pyroxene, or iron oxides. Softer or less durable minerals may round faster than harder ones.

Time Scale: Significant rounding requires long periods. While Mars’ thin atmosphere (about 1% of Earth’s pressure) means slower erosion compared to Earth, the planet’s long history of aeolian activity (billions of years) provides ample time for particle modification.

excursion suits, vehicles and structures will all be positive atmosphere so it should be manageable, no?

Well that's something I'm not going to worry about.

It can’t be any worse than places like LA where every morning about two hundred thousand leaf blowers are fired up and proceed to blow everything that ever touched the ground into the surrounding atmosphere. Smog was replaced with fine particles of toxic dust, such as dog poop, insecticides, urine, vomit, and other cooties emanating from humans, rodents, little hoggers etc.

Dust can be in no matter how much filtering you use...........

I remember my first day in L.A. in the Marines headed for 29 Palms MCB.

I got on the bus headed for Palm Springs And sat up front a was talking to the driver.

I looked out and said it sure is a foggy day today! He laughed and said that’s not fog, that’s SMOG!!!!.........

We need to find an Earth-sized planet orbiting a Sun-sized star, not in a binary star system, and with a Moon-sized moon orbiting the planet to produce Earth-like tides in Earth-like oceans, and that has an Earth-like axis tilt to give seasons. And the planet needs an Earth-like core generating a Earth-like magnetic field as a cosmic ray shield as well as Earthlike plate tectonics. And don’t forget an Earth-like N2-O2 atmosphere with traces of CO2 and the inert gases.

Oh, yeah, the Earth-sized planet should not already have extraterrestrial inhabitants.

Sounds like hog dust in confinement buildings.
We all survived that

He should at least stay in the mammal class or worst case, the chordata phylum....
