PAYLOAD
Falcon 9 delivers payloads to space aboard the Dragon spacecraft or inside a composite fairing.
DRAGON SPACECRAFT
Dragon carries cargo in the spacecraft’s pressurized capsule and unpressurized trunk, which can also accommodate secondary payloads. In the future, Dragon will carry astronauts in the pressurized capsule as well.

COMPOSITE FAIRING
The payload fairing is for the delivery of satellites to destinations in low Earth orbit (LEO), geosynchronous transfer orbit (GTO) and beyond.

INTERSTAGE
The interstage is a composite structure that connects the first and second stages and holds the release and separation system. Falcon 9 uses an all-pneumatic stage separation system for low-shock, highly reliable separation that can be tested on the ground, unlike pyrotechnic systems used on most launch vehicles.
FIRST STAGE
Falcon 9’s first stage incorporates nine Merlin engines and aluminum-lithium alloy tanks containing liquid oxygen and rocket-grade kerosene (RP-1) propellant. After ignition, a hold-before-release system ensures that all engines are verified for full-thrust performance before the rocket is released for flight. Then, with thrust greater than five 747s at full power, the Merlin engines launch the rocket to space. Unlike airplanes, a rocket's thrust actually increases with altitude; Falcon 9 generates more than 1.7 million pounds of thrust at sea level but gets up to over 1.8 million pounds of thrust in the vacuum of space. The first stage engines are gradually throttled near the end of first-stage flight to limit launch vehicle acceleration as the rocket’s mass decreases with the burning of fuel.
