So yesterday Space-X demonstrated reusability in the Falcon 9 Booster. They are hoping for 10 at this stage, so...2 down.
With periodic major referbishment they hope for 100 shots per Booster.
USA, Space-X Falcon 9 (2010-2017)
USA, Space-X Falcon 9 Heavy (First flight late 2017)
The current Space-X Boosters.
Hopefully the Heavy will fly by the end of the year and in 2018 that Moon flyby could maybe happen.
Space-X does tend to fall behind schedule
but hey, it's only Rocket Science!
On the exciting side: Elon is already driving down launch costs among his competitors.
