    "body_text": "The authors classify satellites, rocket bodies and debris against three brightness thresholds tied to different levels of astronomical interference. For objects brighter than magnitude 7, they estimate a 15% chance that one crosses a ten-second exposure covering a ten-degree-square field, while the chance that at least one object is visible to an unaided observer under dark skies reaches 59% across nighttime hours. Satellites dominate bright observations among objects launched during the constellation era. Extrapolating operators' stated million-spacecraft plans, the paper warns that nearly every several-second, several-degree image could be contaminated for hours each night. The projection depends on launch plans and modeled scaling, not a completed constellation count.",
