The ideas of moonbases and lunar colonization have been with us for a long time, but might realized sometime in the 21st century---maybe "Moonbase 2100"---but they will probably be robotic since low gravity is NOT a healthy environment for humans (see Wikipedia: Weightlessness: Human health effects)---and who'd want to live on the Moon for more than a lunar month = 29.530588861 days (J2000).
