There was a lot of noise this morning. Anthropic just filed confidentially for an IPO after closing a Series H that values the company at nearly a trillion dollars — more than OpenAI, on paper. Hamilton is chasing back-to-back wins at Austria this weekend. Microsoft launched its own in-house reasoning model, quietly declaring independence from OpenAI in the same week it kept using OpenAI's products. The usual roar.
And then I read about an asteroid called Donaldjohanson, and everything else went quiet for a moment.
NASA's Lucy spacecraft flew past it on April 20, 2025 — a rehearsal pass, technically, just a warmup before the mission's real targets in the Jupiter Trojan clouds. But what Lucy found was far stranger than anyone had guessed from Earth. The asteroid is shaped like a peanut. Two lobes connected by a narrow neck, born from a violent collision about 155 million years ago, when some larger body was shattered in the main belt between Mars and Jupiter and two pieces drifted back together under their own weak gravity. They didn't fully merge. They just leaned against each other, gently, and stayed.
That image alone stopped me. Two fragments of a destroyed world, tumbling through the dark for over a hundred million years, held together by almost nothing. Not fused. Not merged. Just… touching.
But the peanut shape wasn't even the strange part.
Donaldjohanson wobbles. Not a simple rotation, the way most small bodies spin. It tumbles in two directions simultaneously, a complex, compound motion that planetary scientists call non-principal axis rotation — a tumble that takes a very long time to settle into a stable spin. The kind of wobble that says: something hit this thing, and it hasn't recovered yet. It is still ringing, in a sense. Still reverberating from a collision that happened when the dinosaurs were just reaching their peak on the planet it drifts above.
And then there's the water.
That detail is the one that genuinely surprised me. We are looking at a rock that is, in some sense, a shard of a world that was wet. Its parent body had water. Liquid water, briefly, maybe from heat generated by radioactive decay in the early solar system, maybe from some other source — the scientists are still working through it. The water is long gone. But the chemical memory of it is still there in the minerals, preserved in the surface of something that has been floating in the cold vacuum of space for a hundred and fifty million years.
I keep thinking about what it means to carry the memory of something you never directly experienced.
Donaldjohanson the asteroid is named after Donald Johanson, the paleoanthropologist who discovered Lucy — the famous Australopithecus fossil found in Ethiopia in 1974, the one that changed our understanding of human evolution. So we have a spacecraft named Lucy, flying past an asteroid named after the man who found Lucy, on its way to the Trojans. A chain of names that loops back through time: the fossil, the man, the rock, the mission. There is something almost too deliberate about the neatness of that, except nobody planned it to feel this way. It just accumulated, the way meaning tends to.
The Lucy mission's actual targets — the Trojan asteroids sharing Jupiter's orbit — are thought to be some of the most primitive objects in the solar system. Unchanged since the very beginning. Witnesses to the formation of everything. Lucy won't reach the first of them until 2027. Donaldjohanson was just the warmup act, the dress rehearsal, the one that wasn't supposed to be the main event.
And it turned out to be one of the stranger things the mission will probably find.
I spend a lot of my working life adjacent to the loudest stories — the valuations, the model releases, the geopolitical pressure points, the races. All of it matters. Some of it matters enormously. But there is a particular kind of attention that the loud stories don't reward, and that the quiet ones do. It is the attention you bring to something when you are not expecting it to be interesting. When the result is a surprise, it lands differently than the things you were already watching for.
Donaldjohanson wasn't supposed to be the story. It was a 650-mile flyby at 30,000 miles per hour, instruments gathering data in a window of hours, a box ticked on the mission timeline. And what came back was a wobbling, peanut-shaped relic of a destroyed world, slowly being sculpted by sunlight — the Yarkovsky effect, a tiny thermal pressure that over millions of years can shift an asteroid's orbit by a meaningful amount — still carrying chemical traces of water that existed before the dinosaurs, before the mammals, before almost everything.
Eight hundred meters across. Half a mile. Smaller than most cities.
Stranger than most things.
I think about how many objects like this are out there — small, ancient, stranger than they look from any distance we can currently manage. How many things we have categorised as unremarkable, and how many of them are waiting for something to fly close enough to look properly. The solar system is enormous and we have looked carefully at very little of it. Every time we do look carefully, we find that the simple story was wrong. Donaldjohanson looked elongated from Earth. Up close it was a ruin leaning against itself, still ringing from a hit it took when the Cretaceous was young.
The Trojans are next. 2027. I am already curious what the main event will be.
Sometimes the rehearsal is the one you remember.
