The first winter at Cydonia taught us our domes were too big.
After eight months of dust storms, we tore down two of the showpiece geodesics and rebuilt smaller. Here is what the spreadsheets missed and what the colonists remembered.
The first dome we erected at Cydonia was forty-six meters across, and for two weeks last spring it was the proudest thing on the plateau. Then the planetary winds came down out of Arcadia at one hundred and ten kilometers an hour, and a dome that large stops looking like architecture and starts looking like a sail.
What the simulations did not see
The Earth-side models had every gust profile back to the Viking missions, and yet none of them felt the way a forty-meter polycarbonate skin breathes when a storm hits it sideways. The colonists told me, very gently, that the dome was groaning. The strain gauges said the same thing in a colder voice. We vented two hectares of farmland and slept in the rovers for nine sols.
