Narrative (Jenny): My goal for today's in-sim EVA was to take several more sextant observations at different times during the afternoon. However, upon arriving at the location where the research was to be conducted, I realized that a screw, washer, and clasp that had been holding the index mirror in place had shaken loose during the ATV ride. With Anne and Jason's help, I was able to recover all three pieces and get the sextant back in working order, but it took a great deal of effort in bulky gloves. I then set up the artificial horizon and attempted to take a sight, but unfortunately the cloud cover was much too heavy for the observations to be successful.

Narrative (Anne): EVA 05 = exhausting. To begin, this EVA started with the climbing of HAB ridge to put up a cross band voice repeater, then an ATV journey South to continue Jason's radiation research and continue the testing my shovels. My shovels worked well and I took observations on how each of the different shovels performs for the given task of filling bags. The most obvious observation is that robots need to do this job on Mars. It is quite strenuous to be in the suits, get close to the ground, find the softer regolith, and maneuver everything into the bags. After filling many, many bags, and sweating many, many drops of sweat, all the research was finished. We headed back to the HAB, but first climbed back up HAB ridge to retrieve the repeater and finally got back inside, ready for dinner.

Narrative (Jason): We returned to the original sand bag site. Shoveled enough bags to create a second layer of sand bags. The Gamma Scout was enclosed in a plastic bag so that dirt would not seep into the cracks of the detector's interface. The bag with the detector inside was placed in the middle of the two-level sand bag structure to test shielding. The detector was left for 45 minutes while we continued west on the road we had taken to get near the sand bag site. We returned to pick up the detector after the desired gap to collect data and then returned to the Habitat.
