I have never understood why there was ever sat connections on the barge to begin with. The barge will ALWAYS have the support ship since it cannot get out to sea by itself. So why not just use a cheap omni or large angle sector antennas (90 or 120 degree) that point towards the support ship, and have the support ship do all the more delicate sat up/down links. Can anyone explain why they would not want to do it this way? Any drawbacks? This is one of the things I never quite understood...
And all of this to save 12 engine-seconds, or about 1.3 more seconds of first stage boost.
The new grid fins are 4*5 feet with claw like features, new metal and 100% reusable!! They are being placed in service within the next few flights, should be super cool to watch:)

But every time I see the video cut out and then suddenly see the booster sitting on the deck makes be chuckle that the conspiracy theorists are going ballistic right then.
42801/2017-038A: 212 x 65512 km x 24.06 deg.42802/2017-038B: 210 x 65641 km x 23.91 deg.
Perigee looks low enough. The first stage should decay quickly.

Does SES-10 still hold the equivalent mass record for GTO-1800 re-usable performance? Was this a burn to depletion campaign? Given what was said by Elon, was this the most difficult (speed, distance) S1 recovery attempt or does SES-9 still hold the record for that?
When is footage of the landing likely to be available?
Surprising are they not suitable for any more than one reuse?
I'd like to see them put Stage 1 telemetry on the left side of the screen and Stage 2 telemetry on the right. During first stage flight they would be identical, then diverge after first stage separation.
The first FH launch could have a lot going on. 2 RTLS feeds, 1 ASDS and the US. That would be footage and telemetry porn.

I'd disagree with that. You can build a buoy with your uplink antenna on it, and run a cable back to the ASDS. Get your antenna far enough from the rocket that it doesn't lose signal. It's certainly within the means of SpaceX, just not worth the expense or the recovery team's labor deploying and retrieving it all the time.

Or, forget the cable, some radio that uses a "not so directional" antenna.Also, RP1 + LOX produces ionized gas - is this true?
