>Btw, how many days worth of rations and water do we have?
For just Stanley? Right now, a few weeks of food, and, so long as there's a water source that isn't too brackish for the filter (like the Landing Site's nearby pond), a full 10-liter container of potable water.

>Also, why can't Allie charge while active?
The pitiful charging rate and short cable length of her travel case's solar panel, mainly. A proper power source will allow Allie to charge on a more enviable timeframe, up to her full seven days' charge.
