We started our Valentine's Day with a morning yoga session led by Commander Melissa. After some breakfast and a bit of free time to work on e-mail and projects, we launched into our science training. John gave us a presentation on biology and André and Melissa talked about geology. We then took the show to the field, where we were taught the basics about field biology and geology.

Our out-of-sim EVA was concluded as the temperature started to drop outside. We returned to the Hab and talked about the various samples that each of us had collected. Ryan then put on an EVA suit and headed outside to plant a Canadian flag up on flag hill.

Tonight we'll be doing some more science briefings, followed by a movie.
