Starship Booster Catch System Record
The public Flight 5 record supports a phase-level explanation of the Super Heavy catch. It does not support invention of proprietary details.
After hot staging, the booster performed a boostback burn and coasted toward the return corridor. Before a catch could be attempted, vehicle and pad criteria had to pass. Super Heavy then performed its landing burn and entered the launch and catch tower interface, where the arms received the booster through its catch hardware.
System boundary
| System | Publicly supportable function |
|---|---|
| Booster guidance and propulsion | Return the vehicle through boostback, coast, and landing burn |
| Navigation and sensing | Support the commanded return and tower approach |
| Flight and ground decision logic | Permit a catch attempt only when required criteria pass |
| Tower and arms | Receive and support the returning booster |
| Catch interface | Transfer load between booster and tower hardware |
| Alternate outcome | Avoid representing an unspecified fallback path as known |
| Postflight work | Inspect vehicle and ground system before any reuse conclusion |
The purpose can be explained at a high level. Removing landing hardware from the returning booster can shift hardware and recovery functions to the ground system. A successful catch can also place the booster at the launch site.
Public copy should not claim a specific payload gain, turnaround time, landing-leg mass, abort trajectory, arm-closing algorithm, tolerance, or structural load without a source.
One catch is an engineering milestone. Reliability requires repeated attempts across conditions, inspection evidence, anomalies, maintenance, and operational use.
