Wind on Mars exists.
Fri You can see pictures of it taken by the Perseverance Rover, and it looks like there’s an ocean of fine black sand that could sink a ship. But there’s no swimming on Mars because there’s no water on the planet’s surface, it’s all frozen underground.
The thin martian air is something to avoid: it would make humans feel endlessly weak. It’s just a gentle breeze, but it’s too cold for comfort. Then there’s something called a Diurnal Cycle of irritating winds that come and go, at regular intervals.
The low atmospheric density means that it’s really winter on Mars every day of the year, even though Mars has four seasons twice as long as ours. And the days and nights would be longer than ours, but you wouldn’t notice because forty minutes either way is not that much.
The daily dust storms on Mars would drive you insane. But the slower speed of sound would make everything seem muffled and distant. You couldn’t just say “how’s your day going here on Mars?” You’d have to shout it out — and so laid-back conversation would land up being stressful and demanding.
Finally, if we died on Mars our bodies would not decompose. There is no known bacteria to break dead bodies down on Mars so, instead, they would mummify over time. Goodbye would be an endless cycle of hellos.
