SpaceX launched a Japanese TV satellite from Cape Canaveral to geostationary orbit last night and also landed the first stage on a floating sea platform. This was a more difficult feat than its previous landing. The GEO orbit trajectory required a more energetic launch that meant the first stage was going faster and higher when it separated from the upper stage and had less fuel margin as well for slowing down. It was all done in the dark as well. But the booster stuck the landing right on the center of the X on the ship.
Here is a video for the SpaceX webcast from shortly before liftoff, through the landing, and to the shutdown of the upper stage when it reached orbit:
Here is a segment showing only the scenes from the landing:
