Saw the 1st stage doing some RCS maneuvers right after separation, but they cut the camera away from that shot pretty quick so I couldn't see exactly what. They're not supposed to be trying to "land" this one, but I bet they're getting aero data in support of the F9-R.

All in all, looks like a good launch. Can't wait to hear about the second burn, which was last flight's sticking point.

Here, look at the left frame at about 3:30. It looks like RCS maneuvers, some guy on reddit claims he saw a relight from his backyard but its not visible in the official video.

A bit better. Yeah, that stage was working pretty hard on something. Hard to say but it may have been turning around, like the F9R would for its first retro burn. Some extra practice wouldn't hurt.

They turned it around to see when it falls apart if not re-lit but falling down the right way (engines first).

Possibly just insuring it lands in designated area, so it does not land on anything important and they do not have to search for it.
