This article estimates the likelihood of orbital debris (OD) penetration of wire harnesses aboard the Joint Polar Satellite System (JPSS) using computer hydrocode modeling techniques, combined with an understanding of the orbital debris distribution predicted by NASA’s Orbital Debris Model (ORDEM 3.0), and an estimate of redundancy of critical wires in typical 6, 18, and 36 strand cables. Based on the unacceptable risk levels associated with these initial results, the article describes an improved protective blanket design that reduced OD penetration risk to acceptable program levels.
