I think one day, some one will have a conversation like this:

Person A (A): 'hi how are you doing
Person B (B): 'not much, where are you ?'
A: 'I am in the moon, just want to say hi'

This  is can be possible because recently NASA  have a plan to build a colony at the south pole of the Moon around 2020, and it will host for several first wave are the scientists. And moreover together with British National Space Centre , Nasa want to deploy  some kind mobile phone network that allow people to make a phone calls and text messages to Earth. Hmm...  I know it kind a weird thing, but if you want people to stay on the moon, you have to provide this kind of thing right? next to adult channel (joke inside)

This plan is call Moonlite, ands start to build on 2012.

Can you imagine that you will play a moon lander game on your 'moon mobile phone' really at the surface on the moon. just like I say, it's awesome
