The rocket builds itself in public

Aerodynamic fairing. The part everyone screenshots. Houses recovery and payload.

Drogue + main parachute deployment so the vehicle comes back in more than one piece.

Pressurized compartment for the mission payload. Currently reserved for a very brave action figure.

Live downlink of altitude, velocity, and vehicle health to Mission Control.

Responsible for navigation and flight control. Runs the guidance loop and aborts.

Power distribution, sensor harness, and the nervous system tying every module together.

Propellant tanks, plumbing, valves, and pressurization. Holds the go-juice.

Liquid bipropellant engine. The loud, expensive, slightly terrifying heart of the vehicle.

Reinforced static-fire and launch stand. Holds the vehicle, absorbs thrust, and keeps the garage floor mostly intact.

Ground station: laptops, antennas, and the big red button no human is allowed to press.
