Some missions feature first-stage boosters landing while the second stage is still climbing, showing controlled returns that align with ongoing orbital insertion.

Starship’s upper-stage engines ignite before full separation (hot staging), placing exhaust near the booster and signaling a unique separation technique.

Falcon 9 uses propellant itself to assist steering, leveraging high-pressure kerosene for thrust-vector control instead of an auxiliary hydraulic system.

Crewed boosters have been reused for subsequent missions, including uncrewed cargo flights, indicating crew-rated hardware is not limited to a single mission.

Starship’s Super Heavy booster aims for ground-based tower catches rather than leg landings, with multiple recoveries demonstrated across flights.

SpaceX recovers and reuses fairing halves, with previously flown halves employed on hundreds of missions by early 2025.

SpaceX continues to redefine recovery and reuse by rethinking onboard system use, propulsion management, and stage separation across multiple rocket designs.

Beyond returning boosters, the company applies onboard hardware innovations and reusability concepts across various missions to optimize performance.

During stage separation, compressed gas or pneumatics push the stages apart, enabling functional checks of hardware before flight.
