The second stage will burn up upon re-entry into the earth’s atmosphere.

Stage 1 has touched down on the drone ship in the Atlantic.

Essentially, this means the spacecraft is travelling exactly as it should, or, according to the Federal Aviation Administration: “if all vehicle aerodynamic parameters are exactly as expected, if all vehicle internal and external systems perform exactly as planned, and there are no external perturbing influences (e.g. winds) other than atmospheric drag.”
