    "body_text": "Hubble’s CCDs act as long-running radiation dosimeters in low Earth orbit. Empirical functions can correct more than 99.5 percent of the image-quality effect, but the most accurate fits require physically implausible parameters; realistic parameter choices fit worse. The mismatch highlights how local radiation environments complicate forecasts of spacecraft degradation and useful life.",
