Narrative: The Crew Geologist Helen, with the support of the Executive Officer Cesare, set up a soil wetting experiment: after selecting an appropriate clay-rich area, she mounted a shaft to hold the probe of an ASD Visual and Near-Infrared (VNIR) spectrometer. First, the crew took a spectrum of the dry soil. After wetting the soil with 1 liter of water, Helen took initial spectra 2 minutes apart, then 3 minutes apart, 5 minutes apart, and 10 minutes apart, over the course of 2 hours, to measure the evolution of the spectra during the drying process. The EVA ended when the battery of the field laptop ceased working.
