Description Dragonfly Student Guest Investigator - Dragonfly Mass Spectrometer (DraMS) Support Science Database Background: Titan, the largest moon of Saturn, supports organic synthesis in its atmosphere, and is believed to host a deep, potentially habitable ocean under its icy surface. The Dragonfly mission will include the Dragonfly Mass Spectrometer (DraMS) instrument which will analyze and determine the chemical composition of samples that are drilled from the surface of Titan, specifically targeting organic molecules. At its core, DraMS is an ion trap mass spectrometer that measures ions (charged molecules) based on their molecular mass, which is related to the chemical structure. Solid samples are delivered to the inlets of DraMS by the sampling system, and the molecules in the solids can be probed in one of two ways: (1) Laser desorption mode (LDMS), in which heavy molecules are “zapped” with an ultraviolet laser to create ions that are sent into the ion trap, and (2) Gas chromatography mode (GCMS), in which samples are gradually heated to ~600°C (>~1100°F) in an oven, and the gases that are released at different temperatures are sent through gas chromatography columns that separate them out by size and type before an electron beam converts them into ions for measurement in the mass spectrometer. These two modes allow DraMS to probe different aspects of the sample composition. Consistent gathering and archiving the scientific data related to DraMS development will provide essential resources for the analysis of Titan’s samples. The scientific data may include data from commercial mass spectrometers, data from the DraMS prototype, engineering, and flight models, and potential from other science instruments related to DraMS. More information on the Dragonfly mission and instruments can be found in the videos at Dragonfly - Gallery Applications are due by June 9, 2025; selections will be made in August, 2025. Description: To create this consistent archive of DraMS-related scientific data, we seek a student who will help design a sample catalog that allows the Dragonfly science team to efficiently search data in the archive and to develop a data processing pipeline to get the data from laboratory systems into the archive. The archive we used is called XINA, and is an integrated online data management platform developed at NASA GSFC, hosted on Amazon Web Services, that archives and allows search and visualization of mass spectrometry datasets. Specifically, the student will work with DraMS software engineers and scientists to gather the LDMS and GCMS data and develop code to store this data on XINA. In this project, the guest investigator will: Receive training in order to understand the basics of LDMS and GCMS data and metadata Work with the DraMS science team to Identify and gather DraMS-related data collected over multiple years from various commercial laboratory instruments and flight-like instruments at NASA GSFC and in partner laboratories in France Work with the DraMS science and software teams to ensure the XINA archive, user interfaces, and collected metadata support the required functionality Develop Python scripts to convert the LDMS and GCMS data into the proper format to be uploaded to to XINA web interface Work closely with the XINA team to create datasets, including appropriate metadata, for each specific laboratory instrument and upload the data in the proper format Create documentation about data processing and data archiving pipeline Depending on progress and team availability, in the second year the student would gather and add the data from the laboratory instruments at our partner institutions in France (e.g., LATMOS). This may require international travel. This project will primarily be completed in laboratories at NASA GSFC but in close collaboration with French GCMS colleagues residing at several institutions (Laboratory for Atmospheres, Observations, and Space, or LATMOS, and Process and Materials Engineering Laboratory, or. LPGM). Outcome: This project will enable the Dragonfly science team to easily get online access to DraMS-related research data that was collected over the last ~7 years and will continue to be collected throughout the mission. Both LDMS and GCMS measurements from various laboratory commercial instruments, flight-like instruments, and the DraMS engineering and flight models will be collected. This archive will aid the scientists in their analysis, interpretation, and comparison of future DraMS results and will help prepare for surface operations on Titan.
