19 cards and growing — every session adds more. Each card holds verified facts, a deep read, and prompts designed to be pasted into any AI agent. Knowledge built for humans and machines at once.
A ~226 km metal-rich world — possibly the exposed core of a shattered protoplanet. NASA's Psyche spacecraft arrives in 2029 to find out what it actually is.
Open cardA carbonaceous rubble pile that gave us 121.6 grams of pristine early solar system — organics, hydrated minerals, and a 1-in-2,700 impact question for 2182.
Open cardThe main belt's dwarf planet: ~940 km across, roughly a quarter water by mass, with salty brines still seeping to its surface. The belt's natural depot.
Open cardThe first asteroid ever orbited and landed on — in 2001, with a spacecraft never designed to land. Proof that NEA prospecting is solved, decades-old engineering.
Open cardForged in neutron-star collisions, delivered to Earth's crust by late impacts. Gold's scarcity is an astrophysical accident — all of it ever mined fits in a ~22 m cube.
Open cardThe fusion endpoint and the most load-bearing element of civilization. Iron cores trigger supernovae; iron asteroids are exposed hearts of shattered protoplanets.
Open cardEarth's PGMs mostly sank into the core; some asteroids carry concentrations above the richest mines. The catch: return too much and you crash the price.
Open cardWater is propellant, shielding, and life support in one molecule. The near-term asteroid-mining business case is volatiles for in-space refueling — not platinum for Earth.
Open card0.38 g, a whisper of atmosphere, and the first place humanity made oxygen on another world. The case for Mars is a systems-engineering problem, not a romance.
Open card2.5x the mass of every other planet combined — the solar system's gravitational architect, debris shield (debatably), and free momentum source for every outbound mission.
Open cardOur barred spiral home: 100,000+ light-years across, 100-400 billion stars, a 4-million-solar-mass black hole at the center — and we've mapped a sliver.
Open cardThe nearest large spiral, a trillion stars, 2.5 million light-years out — and the long-promised collision with us may actually be a coin flip.
Open cardEvery element has a spectral barcode. Reading starlight revealed what stars are made of, found helium before Earth did, and proved the universe expands.
Open cardOrbits are perpetual falling. Kepler described them, Newton explained them, Einstein corrected them — and delta-v, not distance, is the true cost of going anywhere.
Open cardHow stars burn: quantum tunneling lets hydrogen fuse at 'only' 15 million K, releasing 0.7% of mass as energy — and the ladder ends at iron.
Open cardThe Big Bang made hydrogen and helium. Stars forged everything up to iron. Exploding stars and colliding neutron stars made the rest — including you.
