'We could be living on the moon by 2022': Nasa claims a 'cheap' 10 billion lunar base will be ready for humans in just six years

It is widely regarded as one of the greatest human achievements ever made, but putting a man on the moon was no cheap undertaking. The Apollo missions to send just 12 men onto the dusty lunar surface cost 25 billion ( 17 billion) – estimated to be worth around 170 billion ( 120 billion) in modern monetary value. But it appears we may be able to send humans back to our rocky satellite and set up a permanent base where they could live for just a fraction of the cost. The cost of building a base on the moon could be a fraction of what has been previously expected. Scientists say it may be possible to build a permanent base (illustrated) housing 10 people within the next five to seven years for around 10 billion.
