RP-2 is a type of rocket propellant used primarily in space exploration. It is a refined version of kerosene, specifically designed to provide high performance and efficiency for rocket engines. This fuel is commonly used in combination with liquid oxygen, creating a powerful thrust that helps launch spacecraft into orbit. The use of RP-2 is crucial for various space missions, including those conducted by organizations like NASA and private companies such as SpaceX. Its reliability and effectiveness make it a preferred choice for many launch vehicles, ensuring that they can carry satellites and astronauts safely into space.
