Back in ‘99, I was 18, workin’ for my uncle on a porch project. He handed me the mixer and said, “Just follow the recipe.” I did. Or so I thought.
I got the water-to-cement ratio all wrong. Too much water, not enough sand. When the slab dried, it looked like a cracked eggshell. My uncle didn’t yell. He just said, “Now you know why we measure twice.”
That cracked slab? I kept a piece of it. Turned it into a paperweight. Every time I look at it, I remember: imperfection ain’t failure. It’s a lesson.
Now, when I think about buildin’ domes on Mars, I see that same spirit. We’ll pour concrete in low gravity, mix regolith with binder, and maybe we’ll crack a few times. But that’s where the magic happens. That’s where we learn to adapt, to improvise, to make beauty out of mistakes.
So here’s to the first pour. To the cracked slab. To the lessons that stick with you. And to the colony we’re buildin’—one imperfect, beautiful pour at a time.
