This EVA had four crew members and was approximately 8km total.

The crew proceeded to location 161 on the ATV's (#1, 3, 4, 5). On the site, a the most interesting locations were selected to run the experiment "EVA communication study". 2 runs were accomplished, first Lucie and Duarte with Tiffany and Louise as observers and then the roles inverted. No more runs were possible to accomplish today due to the unavailability of sand sample containers for 2 more runs. The crew returned back to the habitat topped off the ATV tanks and applied rain protections. The static water tank was then filled and the engineering completed.
