New Antarctic Research Station

The winning design is modular and mobile. While the translation to a lunar / Martian base is loose, the experience of building and implementing this station in the Antarctic might prove invaluable to nations gearing up to construct lunar facilities.

To consider:

What challenges might you face building a base on the Moon?
What would you build your base out of? Why?
What facilities / functionality would you want? (ie. greenhouse, exercise, geology lab, astronomy, etc)
