Narrative: This EVA intended to serve two experiments: GeoMars and Track and Trace. While the first one meant that the EVA was to obtain specific samples on pre-defined waypoints, the later one implied that two EVA crew members were equipped with special EVA suits. G. Grömer wore a space suit that was set to measure forward contamination by three special patches prepared with micro-spherules, while N. Frischauf wore the sterilised silver-plated cover above the analogue space suit. On it were 8 biological sample collectors that were added on in the airlock only, to collect samples throughout the whole GeoMars EVA to quantify backward contamination. Having learned from the first track & trace EVA we fixed the bio-sample collectors with additional tapes, to not loose anyone. This strategy worked and so when the EVA had finished we still had all the collectors on, Track and Trace was therefore from this perspective a major success, as was GeoMars itself, since we were able to obtain 7 samples, including one 55 cm deep drill.
