SpaceX’s Falcon 9 is the primary orbital class rocket able to reflight. It is a two-stage, reusable rocket which might transport each astronauts and payloads into Earth’s orbit and past. It can ship payloads to Lower Earth Orbit(LEO), Geostationary Transfer Orbit(GTO) and even to Mars. The rocket has executed a complete of 256 launches.
Falcon 9 is 70 metres in size and has a diameter of three.7 metres. It is able to delivering a payload of 4020 kg to Mars. The rocket can transport payloads weighing 22,800 kg to LEO and 8300 kg to GTO.
The rocket is powered by Merlin engines. The engines use rocket grade kerosene (RP-1) and liquid oxygen as rocket propellants.
The two-stages of Falcon 9 rocket are merely known as first stage and second stage. The first stage and second stage are linked by means of a construction known as the interstage.

Falcon 9 first stage
Falcon 9’s first stage is powered by 9 Merlin engines. The rocket propellants specifically rocket grade kerosene (RP-1) and liquid oxygen are saved in aluminum-lithium alloy tanks inside the primary stage. The propellants assist it generate greater than 1.7 million kilos of thrust at sea stage.
The first stage is absolutely reusable, thereby lowering huge prices of area exploration. The reusability is feasible because of the primary stage’s touchdown legs. The 4 touchdown legs are manufactured from carbon fiber with aluminum honeycomb.
Falcon 9 second stage
The second stage is powered by a single Merlin Vacuum Engine. This stage is chargeable for the protected supply of payload which can include astronauts.
This stage comes into motion after the primary stage separates from the rocket. Remarkably, the engine on this stage might be restarted a number of instances to position a number of payloads into completely different orbits.
