Scene Context: Upon exiting the shelter, the crew sees that the thermal insulation foil on the outer sector has darkened, wrinkled, and blistered in places.
Essence of the Phenomenon: Kapton and related polymer films are actually used in spacecraft multi-layer insulation (MLI). Radiation, ultraviolet light, surface charging, and extreme thermal cycling can gradually degrade polymers and their optical properties.
Scientific Basis: Multi-layer insulation is a standard part of passive thermal control in spacecraft. These films must both reflect thermal radiation and survive the space environment without losing their essential properties over long missions.
Current Limitations: A single flare does not necessarily turn functional thermal insulation into "charred parchment" instantly. In the scene, this image should be interpreted as a visually amplified consequence of a severe solar event for a ship that has been without atmospheric protection for an extended period, rather than the guaranteed standard outcome of every X20.
