Design Blueprint: A Cryopump Freezer for Acquiring Martian Carbon Dioxide for Propellant Production Sized from Compression and Frost Bounds

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24152077): This paper presents the sizing of a surface system for Mars, designed around a single operating principle and computed from published material properties of its working environment. The headline results are: carbon dioxide capture of 80 kg/day; refrigeration load of 694.444 W; cryocooler power of 5,787.037 W. The total mass is 82.8 kg including a twenty percent margin over the component subtotal. Every figure was produced by the accompanying computation script from stated assumptions about density, strength, thermal properties and composition; no figure is asserted without its derivation. Weak Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
