Firm will 'fly to the moon by 2020'
On the 40th anniversary of the final manned mission to the Moon, Nasa's Apollo 17 mission, a private US company says it intends to fly to the moon by 2020.
The company, Golden Spike - backed by former Nasa employees - plans to use existing rockets to reach the lunar surface, and is selling tickets for $1.4bn (£871m) per pair.
