Robust Mission-Lifetime Screening of ALD-Protected Bio-Based PLA under Uncertain Low-Earth-Orbit Atomic-Oxygen Exposure: Reproducibility Package
Abstract
Executable reproducibility package for the study “Robust Mission-Lifetime Screening of ALD-Protected Bio-Based PLA under Uncertain Low-Earth-Orbit Atomic-Oxygen Exposure”. The archive contains the source-derived data tables, Python analysis code, generated numerical outputs, publication figures, regression tests, pinned software environment, provenance information, and checksums required to reproduce the computational results. The workflow includes the NASA chemical-model implementation for polymer atomic-oxygen erosion, PLA erosion-yield scale corroboration, external validation against later MISSE-9/10/12 ram-facing flight measurements, closed-form mission-severity and architecture decision boundaries, and deterministic framing-sensitivity analyses. No manuscript, journal submission files, LaTeX source, cover letter, title page, or supplementary manuscript text are included. The 750-cycle ALD condition reported by Vieira et al. is treated as experimentally tested but quantitatively bracketed for the reduced-order decision analysis; no graphical-only protection-factor value is digitized and presented as raw data. Running the supplied end-to-end pipeline regenerates all derived outputs and figures and executes the regression-test suite.
