| Recurring |
unknown |
(a) The article does not mention any previous incidents of a similar nature happening again within NASA or with its products and services. Therefore, there is no information available to suggest that this software failure incident has happened again at NASA or with its products and services [83887].
(b) The article does not provide any information about similar incidents happening at other organizations or with their products and services. Hence, there is no indication that this software failure incident has occurred again at multiple organizations or with their products and services [83887]. |
| Phase (Design/Operation) |
design, unknown |
(a) The software failure incident related to the design phase is evident in the article as it mentions an issue with the International Space Station's electrical power system stemming from a main bus switching unit (MBSU) that sends electrical power to two of eight power channels. This issue could be attributed to a design flaw in the MBSU or the power distribution system [83887].
(b) The software failure incident related to the operation phase is not explicitly mentioned in the article. Therefore, it is unknown if the failure was due to contributing factors introduced by the operation or misuse of the system. |
| Boundary (Internal/External) |
within_system |
(a) The software failure incident related to the International Space Station's electrical power system appears to be within the system. NASA mentioned an issue with the main bus switching unit (MBSU) that sends electrical power to two of eight power channels within the ISS [83887]. Flight controllers are working on rerouting power through the remaining channels, indicating that the failure is being addressed internally within the system. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident in this case is not related to non-human actions. The issue with the International Space Station's electrical power system was specifically mentioned to stem from a main bus switching unit (MBSU) that sends electrical power to two of eight power channels. This indicates a hardware-related issue rather than a non-human software failure incident [83887].
(b) The software failure incident is not attributed to human actions in the provided article. NASA is currently investigating the issue with the power system, and there is no mention of any human error or intentional actions contributing to the failure [83887]. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident in this case is related to hardware. The article mentions an issue with the International Space Station's electrical power system, specifically stemming from a main bus switching unit (MBSU) that sends electrical power to two of eight power channels [83887]. NASA is working on rerouting power through the remaining channels to address the hardware-related issue. |
| Objective (Malicious/Non-malicious) |
non-malicious |
The software failure incident mentioned in Article 83887 is non-malicious. The issue with the International Space Station's electrical power system was attributed to a main bus switching unit (MBSU) malfunction, which affected the power channels. NASA mentioned that flight controllers are working on rerouting power through the remaining channels to address the problem. There is no indication in the article that the failure was due to malicious intent; rather, it appears to be a technical issue that NASA is actively troubleshooting and working to resolve [83887]. |
| Intent (Poor/Accidental Decisions) |
unknown |
The articles do not mention any software failure incident related to poor decisions or accidental decisions. Therefore, the intent of the software failure incident in the provided articles is unknown. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The articles do not mention any software failure incident related to development incompetence.
(b) The software failure incident mentioned in the article is related to an accidental issue with the International Space Station's electrical power system. NASA reported that the issue stemmed from a main bus switching unit (MBSU) that sends electrical power to two of eight power channels, affecting the operation of station systems. Flight controllers are working on rerouting power through the remaining channels to address the accidental power problem [83887]. |
| Duration |
temporary |
The software failure incident related to the International Space Station's electrical power system issue mentioned in Article 83887 can be categorized as a temporary failure. NASA mentioned that flight controllers are working on rerouting power through the six remaining channels to address the issue with the main bus switching unit (MBSU) that sends electrical power to two of eight power channels. This indicates that the failure is temporary and efforts are being made to resolve it, rather than it being a permanent failure [83887]. |
| Behaviour |
other |
(a) crash: The software failure incident in the International Space Station article is not described as a crash where the system loses state and does not perform any of its intended functions. The issue mentioned is related to the electrical power system and the main bus switching unit (MBSU) causing a power problem, but there is no indication of a complete system crash [83887].
(b) omission: The software failure incident is not described as an omission where the system omits to perform its intended functions at an instance(s). The issue mentioned is related to a power problem with the electrical power system and the main bus switching unit (MBSU), which is affecting the power channels on the International Space Station [83887].
(c) timing: The software failure incident is not described as a timing issue where the system performs its intended functions correctly but too late or too early. The focus of the incident is on the power problem and the rerouting of power through different channels to maintain station operations [83887].
(d) value: The software failure incident is not described as a value issue where the system performs its intended functions incorrectly. The issue mentioned is related to the power distribution system on the International Space Station, specifically the main bus switching unit (MBSU) causing a power problem [83887].
(e) byzantine: The software failure incident is not described as a byzantine failure where the system behaves erroneously with inconsistent responses and interactions. The incident is centered around the power issue and the efforts to reroute power through alternative channels to ensure station operations continue without immediate concerns for the crew or the station [83887].
(f) other: The behavior of the software failure incident in the International Space Station article is related to a power problem caused by the main bus switching unit (MBSU) affecting the electrical power system. The incident does not fit into the categories of crash, omission, timing, value, or byzantine failures. The focus is on troubleshooting the power issue and its potential impact on upcoming missions [83887]. |
