Job Description:
This individual will need to be able to immediately work on a variety of projects within our group. Approximately 0.20 FTE per project but able to handle shifting priorities amongst the five projects below:
•S.A.M. (Spacecraft Atmospheric Monitor): Design, characterize and prepare the hydrogen carrier gas system of S.A.M. that will be demonstrated on the International Space Station. Determine lifetime characteristics of the metal hydride tank, including its behavior in various temperature conditions. Design and build a hydrogen fill station to prepare the metal hydride component for flight and document an optimal filling procedure. Assist the team in developing, building and using a station intended for bonding microvalve chips that are necessary for the MEMS-GC.
•MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment): Develop dynamic performance models of MOXIE for the Mars 2020 rover. Create and maintain a physics-based model that simulates operation on Mars and guides the design of the instrument’s run control sequence in the flight software. Design control system algorithms for the Solid Oxide Electrolysis (SOXE) process and MOXIE system pressure control. Test flight hardware gas compositional optical sensors and pressure transducers to evaluate measurement capability and establish communication protocols.
•ELF (Enceladus Life Finder) Strategic R&TD: Improve design of the Quadrupole Ion Trap Mass Spectrometer with potential to analyze ice grains from Saturn’s moon, Enceladus. Develop the trap geometry and material design in order to optimize the detection of fatty acids that may indicate the presence of life. Design and test the collision gas system that will aid the soft ionization in the Mass Spectrometer. Design the system that will deliver fluorinated calibration gas. Determine the best transfer line dimensions into the ion trap and operation parameters for the Mindrum microvalve based on quality of the mass spectra.
•In-Situ Resource Utilization Technology Project (AES-funded): Gather technical info on various In-Situ Resource Utilization (ISRU) and Environmental Monitoring sensor technologies throughout various NASA flight and research projects. Design a carbon dioxide and carbon monoxide separation system intended for a Solid Oxide Electrolysis Oxygen production plant on Mars.
•Water Monitoring Project (AES-funded): Set up operation of Total Organic Carbon Analysis (TOCA) commercial and Small Business Innovation Research (SBIR) instruments intended for environmental monitoring. Will design enhanced water analysis “front-ends” for our MS-based sensors.
