  1. If martians sent spacecraft to these same latitudes and longitudes on Earth, what would they find? Would they find life or an advanced civilization?
  2. If you were a martian, why would you explore the Earth? Does Earth have resources you might need? What would you want to know about the Earth? Where would you land first?
