SpaceX going all in to launch unmanned BFR to Mars by 2022

All SpaceX rocket development decisions are to accelerate the earliest completion of the SpaceX BFR.

SpaceX will no longer divert resources to make the Falcon 9 second stage reusable. The second stage modification for a mini-BFR will enable low-cost testing of the BFR upper stage.

SpaceX will shift all development resources towards the BFR by the end of 2019. SpaceX is currently spending on the crewed Dragon.
