16 Jan
The day was greeted with snow and fairly strong winds. It was interesting to see how the structure basically "shed" the accumuation as the day progressed. We finished the final sensor placements. There is a certain amount of calibration required once the sensors are in place, so that was also accomplished. The connection back to Johnson Space Center was also utilized during a good part of the day. As far as the structure, we demonstrated the use of the “regolith bags”. Some concepts for providing radiation protection on the lunar surface includes using local resources (lunar soil) placed into containers and placed over the lunar habitat. Here at McMurdo we incorporated the same concept using the local resource (snow) on exterior bags that are attached to the Hab. The day was completed with our overnight stay using sleeping bags provided by Byrd Field Center.
