TWO SATELLITE LAUNCHES FROM JULY 25TH:

Falcon 9 launches 10 Iridium satellites. The launch occurs about 21 minutes into the video; booster engine cutoff (BECO) and the boost back burn to return the booster to a successful relanding on a downrange barge occurs at about 25 minutes. Then skip forward to see the 10 Iridium satellites released. The commentary is quite good if you want to watch throughout.

Ariane 5 launches four Galileo satellites. Again, the liftoff occurs about 21 minutes into the video. Unfortunately if you want to listen in, you should be fluent in French.

Both videos are quite long - well over an hour each - so you'll probably want to skip back and forth to catch the interesting parts.
