04. Will we have a global positioning system (GPS) for navigation in space? What else would we have? How will we know where we are going in space? (A K2S Question)

From The Space Library

Looking down at the Earth is like getting a lesson in geography in the most amazing classroom you can imagine. It is a little disappointing at first to realize that there are no big capital letters over each country to tell us their names, and I wished that I had paid more attention in geography class. Soon though, I got better and better at looking at the Earth and understanding where I was. Different places on the Earth have different textures and colors, and after a while I could differentiate between the craggy sharp edges of South America and the smooth high mountains of Africa. It felt wonderful to realize that the whole Earth was my very own neighborhood!
