Does SpaceX have an engine that can be reused or do they just reuse the entire rocket?
SpaceX has developed a reusable rocket system called the Falcon 9. The Falcon 9 is designed to be able to land back on Earth after it has launched a payload into orbit. This allows SpaceX to reuse the rocket for multiple launches, which significantly reduces the cost of access to space.
The Falcon 9's first stage is powered by nine Merlin engines. These engines are designed to be reusable. After the first stage has separated from the second stage, it uses its engines to perform a controlled landing on a drone ship in the ocean. The engines are then refurbished and reused on future launches.
The Falcon 9's second stage is not designed to be reused. It is powered by a single Merlin vacuum engine, which is optimized for use in the vacuum of space. After the second stage has delivered its payload to orbit, it is discarded.
In summary, SpaceX does have an engine that can be reused. The Merlin engines used on the Falcon 9's first stage are designed to be reusable and are refurbished and reused on future launches. The Falcon 9's second stage, however, is not designed to be reused and is discarded after it has delivered its payload to orbit.
