It was forty years ago this month that Apollo 17 took astronauts to the Moon for the last time. Since then, the satellite has only been visited periodically by unmanned probes, but that may change inside the next ten years. On Thursday, the day before the anniversary of Apollo 17’s launch, a new company called Golden Spike announced at the National Press Club that it would be sending commercial exploration missions to the Moon within a decade with a ticket price of US$750 million.
