  •  They all use powered descent. (1+ / 0-)

    The first stage after separation spins around and uses remaining fuel to slow down enough to begin descending vertically, then lands on the pad.  Don't need too much additional heat shielding for that.  The second stage begins to slow down by using a forward heat-shield, then when it slows down enough, spins around and begins powered descent.  Ditto the Dragon.  In an emergency, they might still have parachutes - and if catastrophic failure occurs, they're over the ocean.
