Resumen: We report on thermodiffusion experiments conducted on the International Space Station ISS during fall 2016. These
experiments are part of the DCMIX (Diffusion and thermodiffusion Coefficients Measurements in ternary Mixtures) project,
which aims at establishing a reliable data base of non-isothermal transport coefficients for selected ternary liquid mixtures.
The third campaign, DCMIX3, focuses on aqueous systems with water/ethanol/triethylene glycol as an example, where
sign changes of the Soret coefficient have already been reported for certain binary subsystems. Investigations have been
carried out with the SODI (Selectable Optical Diagnostics Instrument) instrument, a Mach-Zehnder interferometer set up
inside the Microgravity Science Glovebox in the Destiny Module of the ISS. Concentration changes within the liquids have
been monitored in response to an external temperature gradient using phase-stepping interferometry. The complete data
set has been made available in spring 2017. Due to additionally available measurement time, it was possible to collect a
complete data set at 30 ◦C and an almost complete data set at 25 ◦C, which significantly exceeds the originally envisaged
measurements at a single temperature only. All samples could be measured successfully. The SODI instrument and the
DCMIX experiments have proven reliable and robust, allowing to extract meaningful data even in case of unforeseen
laser instabilities. First assessments of the data quality have revealed six out of 31 runs with some problems in image
contrast and/or phase step stability that will require more sophisticated algorithms. This publication documents all relevant
parameters of the conducted experiments and also events that might have an influence on the final results. The compiled
information is intended to serve as a starting point for all following data evaluations.
