Today has been a bit slow of a day. After yesterday's issues with the ATVs, outside help was due to arrive at some point in the day. A small break in sim, but now our science collection will be far more sample sites available. Unfortunately, this lead to a cancellation of all EVAs planned for the day (more geology sample collection). This left us with plenty of time to analyze EVA 4's samples and continue to improve the reliability of the radio system. Tomorrow, we return to our regularly scheduled sample collections and begin the areohashing scouting.
