If you were a Martian, and had five chances to land a spacecraft on Earth, WHAT FIVE LOCATIONS WOULD YOU PICK TO LAND IN SUCH A WAY AS TO LEARN AS MUCH ABOUT THE PLANET AS POSSIBLE? Imagine that you have mapping spacecraft that provide high quality photographs of the surface, but that you know no more about Earth than we do about Mars.
I will give it some thought and offer my suggestions, but I haven't had time to think that far ahead.
