We reported our SOC and hours, then lined up to make movement. After a short trip north along Cow Dung Road, we dismounted the rovers and moved east on foot to confirm the location of Marble Ritual. Once complete, we marked Marble Ritual with a high-visibility VS-17 signal panel for EVA #2, and then moved within 1m to begin core sample collection. We extracted and stored a core sample and took a location marking. We then moved back to the rovers, and returned southward to the HAB.

EVA #2
Author: Nathan Hadland
Purpose of EVA: Terrain familiarization and sample collection
Start time: 1500 hrs
End time: 1545 hrs
Narrative: EVA #2 initiated a 5-minute decompression at 1500 hours, and moved out to Curiosity and Spirit. After reporting SOC and hours, we progressed north along Cow Dung Road. We dismounted the rovers and moved east on foot to the VS-17 signal panel placed by EVA #1. We then moved slightly farther eastward to the ridge with minimal snow cover for sample collection. We collected 3 samples at different stratifications on the ridge and recorded GPS locations. After sample collection, we returned to the rovers and proceeded back to the Hab and successfully pressurized in the air lock.
