Very interesting this core does not have 21-1 or 21-2 painted on it...
This core originally didn't have even "21" painted on it. They started doing that with booster B1029.

Could someone post the URL character string for the technical webcast? I can't figure out how to find it, and our work security is such that I can't see the video links posted earlier.

Much appreciated!

Former intern at KSC gives some very interesting details about 1021:

I've been waiting so long for this! I interned at LC-39A while the refurb was going on and boy did B1021 give us trouble! I'm so happy to finally see my baby fly!

Edit: since people are asking for more info, I'll give a couple fun problems we ran into.

- Trying to upgrade parts from block 2 to block 3, failing to install them three times, then giving up and trying (and succeeding with) a method from block 1
- Trying to remove parts that weren't originally intended to be removable
- Discovering parts on the booster that theoretically didn't exist before it launched

So, 1021 was a Block 2 booster that's been upgraded to Block 3, if this person is correct. More details in the thread.

I wonder if the time to retrofit from B2->B3 is included in the four months "refurbishment" time or not.  I imagine it might be hard to separate those two in some cases.

Can anyone offer a suggestion for the least laggy streaming site? I've tried SpaceX, Youtube, Ustream with varying results.

Let's review the actual discussion:
Ayup. It is about reuse. I guess my brainfart was caused by some people insisting it is about fairing reuse or roomba or whatever and I kneejerked.
Be successful.  Then tell the haters to (BLEEP) off. - deruch
...and if you have failure, tell it anyway.

SpaceX these days = Youtube. Ustream doesn't have a stream of this launch as far as I know.

And in all honesty, if you can't stream Youtube well, your ISP is at fault - potentially doing it on purpose.

I'd say Youtube just because you can select a quality as low as 240p.

Thanks, but I've got a 120 Mbps home connection from a good provider. I've just noticed lag before comparing the various streams. I'll just watch the Technical Webcast on Youtube then, perhaps with the Hosted one on a different system, at very low volume.

Different streams will seem ahead or behind based purely on when you loaded and a bit of luck. If you don't like your luck just reload the page. just load two pages and reload them randomly and you will see that sometimes this one is ahead and sometimes the other.

Sorry, I was too excited thinking that I had something new to offer  ::) I looked through the thread, but not the forum. My bad.

The trick is to set the Youtube playback speed to 1.25x. It will automatically reset to 1x after it has caught up to the minimum delay on a live stream.

The look reminds me a little bit of Shuttle, which always looked a little dingy.  (That sounds disparaging, but it really isn't.  I always loved the Shuttle and that part was unique to it).  I was thinking they would clean it more, and I thought that picture of the Orbcomm2 booster looked cleaner.  But I think it looks great!  The latest picture on the Update thread is just spectacular.

You can really tell when you look at the the interstage flush against the new S2, and the legs.

At the risk of heresy, perhaps Block 5 should introduce a new paint scheme. White isn't the easiest color to keep looking clean.

The 39A HIF pictured today:

Forground booster is defiantly for NROL-76 (gridfins, etc for LZ-1 landing). The one behind todays flight booster though looks like a landed core that's been stripped down (No dance-floor/engines. With the top of the LOX tank visible of the right). The boosters used for CRS-9 is the only one (publicly) unaccounted for cape-side. Interesting though that it is fully cleaned, and even with the leg locking pin wiring still in place.

Not the Immersat-35E booster, as it is still at McGregor, it should depart there after this evenings launch.

Awesome banner image from SpaceX.com of today's flight booster along with two others being prepped for future flights.

Are you sure there are two more stages?  I'm not sure there's one in the back, and the other image on the update thread is showing the payload on the far side of the center aisle.

But at any rate, we see that they can start lining up a new stage before the next one is launched, so a pad delay does not affect (to some extend) the schedule of the next launch.

White paint isn't a fashion choice, not primarily anyways. Thermal control for when out in the (hot) sun.

Big long white thing, 'SpaceX' written along it ;)

What's interesting about that one is that the intertank has been removed and you can see the upper tank dome.
