🛸 Rocket Anatomy

Spin a real Falcon 9 or Starship. Pull it apart to see how the stages come together, and tap any glowing part to find out what it does, with real sourced numbers behind it.

Falcon 9, by the numbers

How tall
69.8 m

About as tall as a 20-storey apartment block, standing on its tail.

How wide
3.7 m

Just wide enough that two cars could park side by side inside it.

How heavy
549,000 kg

That is heavier than 400 cars — and almost all of it is fuel, not rocket.

How hard it pushes
7,600 kN

Enough push to lift 775 elephants straight off the ground.

How much it can carry
22,800 kg

A school bus full of satellites — but only if the rocket does not come back.

To a high orbit
8,300 kg

Higher orbits are much harder, so the rocket can carry far less up there.

What it drinks
LOX + RP-1

Very cold air-juice and very clean lamp oil. One burns, one makes it burn.

The second stage swaps to Merlin Vacuum (MVac): 934 kN of push at 348 s of efficiency, through a nozzle 165:1 wider than the nine engines below it.
