Definition:
Falcon 9 is the world's first orbital class reusable rocket, created and manufactured by SpaceX. It is a reusable, two-stage rocket capable of transporting both people and payloads into Earth's orbit and beyond. Reusability allows to reuse the most expensive parts of the rocket, which diminishes the cost of space access. The standard parameters of the rocket are:
Height - 70 m / 229.6 ft
Diameter - 3.7 m / 12 ft
Mass - 549,054 kg / 1,207,920 lb
The engine used in production of Falcon 9 is the Merlin, which uses 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.
Falcon 9 has already been used in numerous missions or tests (Crew-1 Mission, Crew-2 Mission, Crew-3 Mission, DART Mission) and is planned to be launched in the next ones (for example Polaris Dawn in the last quarter of 2022).
Sample Sentence(s):
"This rocket is the Falcon 9 that successfully reached orbit after 9 minutes and 38 seconds on its maiden test flight." "It was suggested to be launched with a Falcon 9 rocket."
