Launch vehicle
Falcon Heavy
Three Falcon 9 cores bolted into one vehicle: two side boosters that separate, flip and fly home in formation, around a reinforced center core. Twenty-seven Merlins at liftoff make it the most powerful operational rocket of its decade — able to throw real mass at the Moon, Mars and Pluto.

Payload capacity, solved by the engine
Ideal staged-Δv model (rocket equation, Rust) against standard surface-to-destination budgets that include typical gravity/drag/steering losses. First-order — not a flight manifest.
