| Recurring |
unknown |
The articles do not mention any specific software failure incident happening again at one_organization or multiple_organization. Therefore, the information related to the recurrence of a similar incident within the same organization or across multiple organizations is unknown in this context. |
| Phase (Design/Operation) |
unknown |
(a) The software failure incident related to the design phase: The incident of the 38 Starlink communications satellites failing after being launched into low orbit was not directly attributed to a software failure in the design phase. Instead, the failure was caused by a space storm that disrupted the satellites' orbit-raising maneuvers due to disturbances in Earth's upper atmosphere [135207].
(b) The software failure incident related to the operation phase: The incident of the 38 Starlink communications satellites failing after launch was not directly attributed to a software failure in the operation phase. The failure was due to the space storm causing significant drag in Earth's upper atmosphere, preventing the satellites from reaching orbit and leading to their reentry and burning up in the atmosphere [135207]. |
| Boundary (Internal/External) |
outside_system |
The software failure incident related to the SpaceX Starlink communications satellites can be categorized as an outside_system failure. The incident was caused by a space storm originating from the sun, which affected the satellites' ability to perform their orbit-raising maneuvers, leading to their failure and eventual reentry into Earth's atmosphere [135207]. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident in this case was not directly attributed to non-human actions. The failure was caused by a space storm affecting Earth's upper atmosphere, which led to significant drag on the satellites and prevented them from reaching orbit, ultimately causing them to fall back to Earth [135207].
(b) The software failure incident was not directly caused by human actions. However, the researchers highlighted the need for better space weather alerts and forecasting systems to prevent similar incidents in the future. They emphasized the importance of addressing gaps in space physics that could impact prediction accuracy and space traffic coordination in a crowded space environment [135207]. |
| Dimension (Hardware/Software) |
unknown |
(a) The software failure incident in the article was not directly attributed to hardware issues. Instead, it was caused by a space storm affecting the satellites' ability to reach orbit due to disturbances in Earth's upper atmosphere [135207].
(b) The software failure incident was primarily due to the impact of space weather on the satellites, causing significant drag and preventing them from completing their orbit-raising maneuvers, ultimately leading to their failure and burning up upon reentry into Earth's atmosphere [135207]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
The software failure incident related to the SpaceX Starlink communications satellites was non-malicious. The incident was caused by a space storm that affected the satellites' ability to perform their orbit-raising maneuvers, leading to their failure and eventual reentry into Earth's atmosphere [135207]. |
| Intent (Poor/Accidental Decisions) |
unknown |
Unknown |
| Capability (Incompetence/Accidental) |
unknown |
The articles do not mention any software failure incident related to development incompetence or accidental factors. |
| Duration |
temporary |
The software failure incident related to the SpaceX Starlink communications satellites was temporary. The incident was caused by a space storm that created a disturbance in Earth's upper atmosphere, leading to significant drag that prevented the satellites from beginning their orbit-raising maneuvers. As a result, the satellites fell towards Earth and burned up upon reentry into the atmosphere [135207]. |
| Behaviour |
crash, omission, timing, other |
(a) crash: The software failure incident in the article resulted in a crash as 38 of the Starlink communications satellites failed to reach orbit and instead fell towards Earth, burning up as they reentered the atmosphere [135207].
(b) omission: The software failure incident can also be categorized as an omission, as the satellites omitted to perform their intended function of reaching orbit due to the disturbance in Earth's upper atmosphere causing significant drag, preventing them from starting their orbit-raising maneuvers [135207].
(c) timing: The timing of the software failure incident could be considered a factor as well. The disturbance in Earth's upper atmosphere caused by the space storm made it impossible for the satellites to begin their orbit-raising maneuvers at the correct time, leading to their failure to reach orbit [135207].
(d) value: The software failure incident did not directly involve a failure in the system performing its intended functions incorrectly (value).
(e) byzantine: The software failure incident did not exhibit characteristics of a byzantine failure, which involves inconsistent responses and interactions.
(f) other: The other behavior exhibited by the software failure incident was a result of space weather conditions affecting the satellites' trajectory and performance, leading to their failure to reach orbit as intended [135207]. |
