http://www.spacex.com/falcon-heavy It can now take 63.8 tons to LEO at an extremely low cost. Think of the possibilities. You could place some great spaces stations with this. You could land on the moon and come back and more. For comparison. the SLS which will be coming out next year does 70 tons to LEO. Then once it does its test flight. No one will be able to use it at all until 2021 or 2022. It cost a fortune to launch the SLS. Billions of tax payer dollars went into developing it while nothing but the cost of just getting some technical advice went into the Falcon Heavy.
