Today was dedicated to the (successful) completion of testing the stability of our fixed flight computer watchdog system. We did long-ish-term stability tests in the morning and a bunch of shorter tests in the afternoon to look at flight computer memory usage when writing various amounts of data to disk. In the end, we're confident we have a system we can fly, and if any problems arise we have the tools to deal with them in flight.
I mostly did a whole lot of nothing. When we returned to McMurdo we were treated to the base's Christmas dinner -- a movable feast of roast meats (beef wellington and prime rib), seared duck breast, and baked lobster tails along with various sides as well as an impressive array of house-made desserts (pecan pie, buche de noel, fudge, etc) as well as the ubiquitous Frosty Boy softserve, tinted a season-appropriate green.
I didn't get any pictures of the food, though, since I don't usually take my camera to meals and I forgot to do so even on this special occasion. You'll have to make do with pictures of people in the high bay.
