  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.Timeline1317 Enter Airlock1322 Airlock open1336 Leaving hab for 1611345 Arrive 1611410 Started experiment1540 Began return trip1544 Stop to re-attack gear which was getting loose1600 Reached Hab1618 Refuelling ATV/Engineering check1627 Airlock sealed1632 EVA end airlock re-pressurized Issues:1) Lucie dropped ear piece in beginning of experiment runs2) 2 experiment runs could not be accomplished3) Gear was getting loose on the ATV during the way back the way backAdditional Notes:NONE
