将太空人送返月球的竞赛已经展开，这次不仅为插上国旗，而是为了殖民，人类要如何做到？而又所为何事？私营企业及各国政府太空计划正争相制造火箭及机械，以运送人类登月，但不再单为到此一游，而是为了定居。部份人希望开采月球土壤以换取无穷财富，包括可以为地球电网供电数世纪的天然资源。其他人则想一试，有朝一日可以用于火星建立殖民地的科技与技术。不过，月球是个充满敌意的世界，宇宙射线、月震及流星都对人类生存造成持续威胁。本节目会了解现今科学家及工程师，将如何通过殖民月球，去踏出人类巨大的下一步。

Return to the Moon

The race is on to return astronauts to the Moon. This time, not to just plant a flag, but to colonize. How would we accomplish this? And why would we do it? Private companies and government space programs are vying to create the rockets and machines to get us there. Not just to visit. To stay. Some want to mine the lunar soil for untold riches, including a natural resource that could power Earth’s electrical grids for centuries.

Others want to try out technologies and techniques that could someday be used to create a colony on Mars. But the Moon is a hostile world. Cosmic rays, moonquakes and meteors are a constant threat to survival. Discover how today’s scientists and engineers are about to take the next giant leap for mankind by colonizing the Moon.
