I don't know! I cannot seem to figure out why we have not been back to the moon. If we could do it back then why are we not doing it now? Or why are we not try to go elsewhere? Sattlites are good, but nothing is better than going there in person. Why worry about a space station that orbits the earth when you could build something much bigger on the moon? I know the moon is farther away, but they did back in the day. My phone is stronger then their computers back then.
