The Falcon 9 experienced a failure during a routine procedure known as the "deorbit burn," where its second-stage engine failed to properly re-light. This malfunction occurred after the rocket had successfully boosted two astronauts to the International Space Station for NASA.
Understanding the Falcon 9 Malfunction
The failure of the Falcon 9 was specifically attributed to a problem with its second stage, which is the rocket body responsible for carrying the crew further into space after the initial launch phase.
Details of the Incident
- Component Affected: The second stage of the Falcon 9 rocket (often referred to as the rocket body).
- Type of Failure: The engine on this second stage failed to properly re-light.
- Affected Maneuver: This re-ignition failure occurred during a crucial maneuver known as the "deorbit burn."
- Purpose of Deorbit Burn: This burn is a standard and necessary procedure designed to discard the booster safely into the ocean after it has completed its mission in space. It's essential for preventing space debris and ensuring safety.
This malfunction led to the grounding of SpaceX's Falcon 9 rocket fleet by the US FAA while the incident was investigated.
Summary of the Falcon 9 Failure
| Aspect | Detail |
|---|---|
| Component Affected | Second Stage (Rocket Body) |
| Type of Failure | Engine Re-ignition Failure |
| Maneuver Affected | "Deorbit Burn" |
| Purpose of Maneuver | Routine procedure to discard booster safely |
| Immediate Consequence | US FAA grounded Falcon 9 fleet |
Importance of Deorbit Burns
Deorbit burns are critical for responsible space operations. They ensure that spent rocket stages do not remain in orbit as hazardous space debris, which could pose a risk to operational satellites, future space missions, and the International Space Station itself. A successful deorbit burn allows for a controlled re-entry and impact in designated, unpopulated ocean areas, minimizing risks on Earth.
