Falcon 9


What is Falcon 9?

Falcon 9 is a reusable, two-stage rocket designed and
manufactured by SpaceX for the reliable and safe transport
of people and payloads into Earth orbit and beyond. Falcon
9 is the world’s first orbital class reusable rocket.
Reusability allows SpaceX to refly the most expensive parts
of the rocket, which in turn drives down the cost of space
access.

Engines
Merlin
Sea Level
Merlin is a family of rocket engines developed by SpaceX for use on its Falcon 1, Falcon 9 and Falcon Heavy launch vehicles. Merlin engines use a rocket grade kerosene (RP-1) and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for recovery and reuse.

Vaccum
Merlin Vacuum features a larger exhaust section and a significantly larger expansion nozzle to maximize the engine’s efficiency in the vacuum of space. Its combustion chamber is regeneratively cooled, while the expansion nozzle is radiatively cooled. At full power, the Merlin Vacuum engine operates with the greatest efficiency ever for an American-made hydrocarbon rocket engine.
