In Situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio

Chemie Ingenieur Technik, EarlyView.
The rocket propellant methane can be produced on Mars by in situ resource utilization. The H2/CO2 ratio is decisive, and excess H2 is favored for providing sufficient propellant purity. The operation mode—with or without recycling of unreacted reactants—depends on the resource availability of the selected landing site. Abstract For return missions from

Poly(Imide‐Siloxane) Copolymer Materials for Lunar Dust Mitigation: Synthesis and Characterization of Surface Properties

Macromolecular Symposia, EarlyView.
ABSTRACT Dust poses a significant threat to any equipment operating on the Moon, particularly for long‐term explorations. The development of efficient dust mitigation solutions is therefore critical for the success of lunar missions. In this work, fully aromatic and fluorinated polyimide (PI) and poly(imide‐dimethylsiloxane) (PIDMS) copolymers are ...
