Just to be clear, it is not their goal to reuse rockets that are soft-landed in the ocean. This particular attempt was to prove that they could make the rocket slow to zero meters/sec at the surface of the ocean, with it upright. Which they did. Their next attempt will be to target a smaller radius, to prove their aiming accuracy. Finally, after a couple more ocean landings (with possible recovery for analysis purposes), they will attempt to land on dry ground. To do this, they need to prove they can set down within a 1-mile radius. But they believe they should have the same precision of a helicopter. After this, they are aiming for same-day reusability.
