Brief Bio


Dr. Samuel Teinturier is a planetary scientist, physicist and research engineer employed by GESTAR/USRA at NASA GSFC in the Planetary Environments Laboratory (Code 699). His research interest involves designing and using gas chromatography-mass spectrometry experiments on Earth and analyzing data from science payloads onboard spacecrafts in order to identify organic material in space. Dr. Teinturier has a strong background in engineering, computer data analysis and experimental setup.

Current Projects


Sample Analysis at Mars (SAM) Science Team Member

Mars

Dr. Teinturier is a member of the Mars Science Laboratory Science Team since the landing of the Curiosity rover on Mars (2009). He is a member of the SAM team (PI: P. Mahaffy). He contributes to the analysis of the SAM data using complex, multi-disciplinary treatments and experimental set-ups with about 40 scientists and engineers from the SAM team. He is an expert in understanding the SAM instrument and developing, testing and analyzing all the experiments and data from the instrument.
Dr. Teinturier is also a member of the Tactical Operations Team on MSL and acts as a PDL (Payload Downlink Lead) and PUL (Payload Uplink Lead) for SAM onboard Curiosity on Mars.


Sample Analysis at Mars (SAM) Testbed Lead at Goddard

Astrobiology

The SAM testbed is a duplicate of the instrument currently operating on the Mars Science Lab (MSL) rover Curiosity in Gale Crater, Mars. It is run inside a Mars chamber at GSFC which replicates the thermal and atmospheric conditions found on Mars. Dr. Teinturier leads the development, testing, and validation of experimental procedures using SAM testbed before use on Mars. This experiment is a key element of the SAM mission: to test under the same conditions each experiment which will be run on Mars; and to be able to understand the science data from Mars, with the analysis of Mars Analog Samples for instance.


Dragonfly Mass Spectrometer (DraMS) Gas Chromatographic Deputy PDL

Astrobiology

Dr. Teinturier is the Deputy PDL (Product Design Lead) for the GC (Gas Chromatographic) on DraMS (Dragonfly Mass Spectrometer) instrument onboard the Dragonfly mission to Titan.
