Summary: Our ground truthing reconnaissance was planned to explore the “Goblins” near Lith Canyon. However, we had some difficulty finding our GPS waypoints goals and spent a little more time than planned looking for checkpoints. The planned EVA route was to reach the “Goblins” by way of Cow Dung Road passing Pooh’s Corner and all the way to Lith Canyon Rd 1106. We reached the end of Lith Canyon Rd 1106, took photo and video documentation and began our return to the Hab. Additionally, data was collected for Dr. Kobrick’s EVA for a metrics study on human performance physiology and exploration metrics. We set up checkpoints on this EVA at the following locations: Cowboy Corner, Tank Wash, Intersection to Brahe Hwy 1572, intersection to the Quarry Rd, and the intersection to the Lith Canyon 1106.
On the return trip to the Hab, we collected samples of Gypsum between the intersection to the Brahe Hwy 1572 on the Pooh’s Corner and Tank Wash. We will consult with our crew scientist and mission support team to analyze the sample in the science lab. Once the rovers were parked, we walked around the Hab to get more photos before heading back into the airlock.
