Basically the answer to all of those is SpaceX's next gen BFR rocket. It is scaled up significantly which makes second stage reuse practical. The challenge with a rocket the size of the Falcon 9 is that added significant fixed mass to the second stage (heat shielding, parachutes, etc.) will significantly Affect payload mass / performance. By going to a much larger class of rocket, those concessions for re-use become a smaller fraction of the total stage 2 mass. |
