After the day off, we started the new week with some house-keeping activities to clean and tidy up the whole hab. We drew straws (should say toothpicks) to decide who had to clean the bathroom, even if we would have had a volunteer. This seemed to be necessary after about one week of our mission! Especially since the dust of the Martian desert had spread everywhere inside. Also our scientific equipment as well as our personal things had been spreading everywhere throughout the whole hab.

About noon we started the suit-up procedure down in the EVA preparation room. The EVA team consisting of Dave Scott (EVA leader), Simone Kosol and Elia Husiatynski, could leave the airlock after the 30 min period of prebreathing at 11:54 h. After a last check of the greenhab parameters, disposal of waste and deploying of another one of the UV-dosimeters the EVA-team was ready for the plan of today: to find and collect further soil samples from salt containing areas for the search for halophilic microorganisms, to scout for other suitable places for the next drilling EVA for Mark's gas samples and to collect further environmental water samples to test the water contamination measurement system of Mark. All these aims had been achieved during this long ATV EVA over 66 km. The crew came back into the airlock at 16:45h. In between the water tank was checked by someone from Hanksville and we got more oil for the generator which still needs a lot more that it should. Our evening meeting took place at 6:30 right before dinner preparation.
