Discoveries during an investigation of the solid oxide electrolysis cells for the Mars Oxygen ISRU Experiment As humankind expands its footprint in the solar system, it is increasingly important to make use of Earth independent resources to make these missions economically feasible and sustainable. In-Situ Resource Utilization (ISRU), the science of using resources at a destination to support exploration missions, unlocks potential destinations by significantly reducing the amount of resources that need to be launched from Earth. Carbon dioxide is an example of an in-situ resource that comprises nearly 96% of the Martian atmosphere and can be used as a source of oxygen for propellant and life support systems. The Mars Oxygen ISRU Experiment (MOXIE) is a payload being developed for NASA’s upcoming Mars 2020 rover. MOXIE will produce oxygen at a rate of 10 grams per hour from the Martian atmosphere using solid oxide electrolysis (SOXE). MOXIE is a 0.5% scale of an oxygen processing plant that might enable a human expedition to Mars in the 2030’s through the production of the oxygen needed for the propellant of a Mars Ascent Vehicle (MAV). MOXIE draws energy from the Mars 2020 rover’s radioisotope thermoelectric generator (RTG) to power the MOXIE scroll compressor, heaters, control electronics, and SOXE cells to create oxygen and carbon monoxide molecules from the CO2 electrolysis reaction.

Body surface reconstruction consists in obtaining a digital, three-dimensional, representation of a body surface patch, from which quantitative information can be extracted. Optical methods are typically used for this purpose, thanks to their high spatial and temporal resolution, which allow obtaining accurate and time-resolved measurements. One of the several application fields of such technologies is high precision radiation therapy, where body surface reconstruction provides a non-invasive solution for patient monitoring before and during treatment. In this application, optical tracking systems typically support the positioning of the patients before every treatment fraction and provide respiratory motion monitoring. The aim of this work is to test the feasibility of using the DIC camera system, combined with a dedicated software package, to fulfill the above-mentioned tasks. Results concerning geometric accuracy and temporal performances of the system will be presented.
