It's kind of hard to keep track of two launches at once, but...

<blockquote class="twitter-tweet" data-lang="en"><p lang="en" dir="ltr">Static fire test of Falcon 9 at Vandenberg AFB complete—launch of 10 <a href="https://twitter.com/IridiumComm">@IridiumComm</a> NEXT satellites slated for Sunday, June 25.</p>&mdash; SpaceX (@SpaceX) <a href="https://twitter.com/SpaceX/status/877291820962594816">June 20, 2017</a></blockquote>

I've added both launches to the OP, so look there for date and time details.

Launch day bump!

Brief overview on this one: This is Bulgariasat-1, which is the first satellite Bulgaria has ever put into space (they can only afford it because of SpaceX's costs). This booster is the second one that has been flown previously (it was originally flown in January on the Iridium 1-10 mission on the west coast). This is a GTO mission, so the landing will be on the drone ship out in the ocean. If they can recover it, it will be the second one that's been landed twice.

I may be on the way back from a meeting and miss this one live, but we'll see how things go.

Launch pushed back an hour. Now 3:10pm EDT.

Elon doing a little selling.

If they keep a live feed from the booster during reentry, it could be worth the price of admission.

Getting closer.

Seems like we got the webcast "B" team today.

The bump in time means I get to watch it. :)

Webcast is live.

Disappointed no technical cast today. Enjoyed listening in on operations during previous launches.

Huh - that's odd. Any word why no technical today?

Yeah, I kind of agree. Doesn't seem like they put much effort into this one.

Nope, haven't seen any explanations. Wonder if the "A" team is at Vandy?

They're always in Hawthorne regardless of launch location, so who knows?

That's a good point. D'Oh!

Definitely a different format though, and no explanation that I've seen as to why. The only real difference is the expected next launch being 2 days away, then 6 days. Not sure if cadence is playing a part here, since all the commentators are usually technical staff. Maybe they're all just too busy this time around.
