  1. To become the payload
  2. To be reused on later flights ✔
  3. To stay permanently in orbit

Why: A recoverable booster returns after helping launch the upper stage. Reusing major hardware can reduce the amount built fresh for each mission.

Huh, didn't know that: Some boosters land on shore, while others land on ocean platforms.

The dad joke
The booster came back because it believed in second launches.

    Reusability allows SpaceX to refly the most expensive parts of the rocket, which in turn drives down the cost of space access.
