Successful launch....ASDS landing, second stage separation, nose cone deployment....Don't know if it can be called an anomaly, but it sure looked like the water suppression system on the pad was lagging behind the launch count. From previous launch memories, it appeared to come up to full spray a few seconds later than usual.

Just checked Ax-2 launch and I don't see difference, looks nominal.

Would agree, the Ax-2 launch looked similar to today's CRS-28. However, here's a screenshot from yesterday's Starlink 6-4 launch at T-02. Here the water jets are already spraying fully on the horizontal versus just after liftoff. Surprised, but there must be some tolerance for this variation. Would also note that Ax-2 and CRS-28 were both launched from 39A, whereas Starlink 6-4 was launched from SLC-40. Pad design differences could be a contributing factor.

I noticed that too and was thinking, is the water jet making any difference at all?
