Next launch targeting June 14 from Cape Canaveral 45 minute launch window opens at 10:32am ET, 2:32pm UTC

45 minute window is interesting.  I don't think that allows enough time to unload and reload propellent but it does give them some leeway on when propellent loading starts.  Plus how ever long they can allow propellent to warm post loading but I think that is a pretty short time.

45 minutes may be enough to chase away a boat!

I thought this was scheduled for late June? It's now June 14th?

Did we just see a schedule slip to the left, rather than the right? If so, that's the first time I've ever seen that, from anyone. 8)

Another sign of how amateurish SpaceX is. Schedule slips left and right!

Just to put it in perspective, it was scheduled for Q4-15, then 03-16, then 04-16, then 03-05-2016, then 16-06-16, and finally 14-06-16. So, yeah, two days of advancement totally make up for eight months of schedule slips.

What's your point? Schedule slips to the right are common (even for non-SpaceX launches), but changes to the left are virtually unheard of.

Because SpaceX managed to do something faster, somehow they're amateurs. Oh they don't have a lot of fat in their schedules. They don't accept putting some padding in just in case.
I my opinion it just shows how serious they are about fulfilling their manifest.

Yes. The Boeing 702SP electric propulsion commsats are designed for a dual manifest capability. F9 launched another pair last year.

both birds look impressive...  SWEET that we have a date pulled in. That's not amateurish it's awesome. Even 2 days is something.

Officially moved up to June 14.

Obviously the end times are near when launch Windows move left on a schedule.

Great to see this!

Wondered if anyone has thoughts on why the move.

Possibilities:
1. Range availability?  (SFN shows a Delta 4 launch on 6/9 and an Atlas 5 launch on 6/24)
2. Did the customer just call them up and say, "How about moving our launch up a couple of days?"  :)
3. As they were preparing for the launch they just happened to find themselves with a couple of free days with nothing to do so they decided to move up the launch?   :D
4. Next SX launch at SLC 40 appears to be CRS-9 on 7/16.  Does this move result in just enough time to slide in another launch before CRS-9?  (Starhawk92's schedule shows AMOS-6 and JCSAT-16 set for August but didn't hear anything about them wanting to move up).   ;D

Probably other possibilities as well.

Would be especially interesting to hear thoughts from anyone "in the know" about how this decision might have been made but glad for all thoughts.

Thanks!

The comm sat processing is usually 30days. If they would interleave a launch, we should have seen the bird arrive at the Cape already. Unless CRS-9 is delayed in which case the bird might be arriving this week.

Valid as of two weeks ago Monday, is that shipping reviews and packing in the shipping containers has been completed for both AMOS-6 and JCSAT-16 and there mobile GSE. I have found no public indication yet that the satellites have arrived at CCAFS for processing at either offline or online processing facilities on and off of base.

Slightly OT question. Can you stacked 3 Boeing 702 SP birds together for launch?

Something that happens a lot even to native speakers.
And I think his English is a LOT better than our Portugese.

But this is not a grammar issue, it's a semantic one, so the native language is less relevant. I am also not a native speaker but it was extremely clear it was a "nerd" joke.

I'm excited that we are almost at the static fire and we are 8 days out for the next launch and that the last booster is just getting hauled off to the hanger.

It's a nice little flow they are establishing.  With ASDS landings it looks like it will be hard to get much better than a 17 day cycle without adding another ASDS.
1) 4-5 days to get on station
2) ? days to catch the rocket (depending on launch scrubs)
3) 4-5 days return to port
4) 2-3 days unload rocket
5) ? days to resupply and service
5) Repeat

Steps 4 and 5 are where I expect to see schedule improvement... Can't do much about how fast they can travel out and back, but they are already showing improvement at unload time I think?
