SpaceX has recently announced that in the year 2018 it plans to send a couple (identity kept secret for now) for a casual trip around the Moon. A step ahead of the popular Virgin Galactic, which is looking to send people into space for leisure, SpaceX's plans open doors to a whole new industry of space tourism and that too much earlier than any of us had expected.

But before we go ga-ga over SpaceX's pioneering and ambitious plans, here is an info graphic about the very humble Moon that will play a big role in getting the couple back to Earth but is not being given enough credit.
