I've certainly lost count of how many first stage landings SpaceX has made. But, since the first time they accomplished it, they've landing all(except those that just ran out of gas because the launched satellites so far out in orbit).
Anyways, I was watching this, and kind of found the whole excerpt about the Argentina satellite - a large phased arrayed radar. I couldn't help notice all the facilities and the ground satellite dishes to communicate with it. This is all in Argentina alone, much less other countries. It just shows how far science and technology is around the world. View around 11:20 for the video about the Argentina space program and this satellite.
