Is there a chance they're waiting for the first vehicle to arrive before rigging the umbilicals on the erector? Obviously everything is supposed to be measured and modeled, but with Murphy and all....  If the vehicle were actually on the erector as the plumbing was fitted then there couldn't be a need for time-consuming rework after a failed fit-check....

What about running lines up the erector to the point before they drape over to the vehicle.

?? Am I missing something here?

Seems reasonable. But assuming they have the tanks, piping, pre-attachment riggings, etc. all ready to go, how long could it possibly take to finish this out? A week? I don't see this as an issue with over a month out from possible launch. For all we know, they're doing final installs as I write.

But I have another question. Do we have confirmation that fairing, 1st stage, 2nd stage and payload are all now at VAFB being integrated? Just curious.

longer and then there is testing with commodities before connecting to the vehicle.

Good point, forgot about commodities testing.

also to sound like a grouch, don't like how they refer to VAFB as vandy.

I've always liked the original name, Sudden Ranch.

Double connotation. :)

Off topic but "Vandy" is a common nickname for Vandenberg AFB used by USAF personnel stationed there. Less common but also heard are "Vandyland" and "Planet Vandenberg". Source: I was one of those USAF guys stationed there for some years.

Doesn't look like the erector has the umbilicals on it.

I never liked Fanny May either.

It's Fannie May, and their chocolates are wonderful.

They don't refer to it as Vandy. That's only in the names of the JPEG.

yes they do in many other places

Sounds like something they picked up from the Air Force side.  When I was enlisted we had nick names for everything.

I was in the USAF and we didn't refer to it as such.  But enough on this subject.
Then why did you bring it up in the first place? Now we have a number of post polluting this thread, including this one.  :D

And to continue on this: the launch team for IRAS (delta 166 in early 1983) referred to Vandenberg as 'Vandy' as well. That team included people from contractors, NASA, JPL, USAF, etc.
This has been a long on-going tradition. Why it bothers you is beyond me.

A little over a month away from proposed launch date. We should be hearing an update soon on integration of the launch vehicle and the overall pad condition.

If the date isn't announced by the AF then I don't take it seriously.

After looking for a Launch Schedule on the Vandy ( ;) ) website, I found out that;
"Information on upcoming Vandenberg launches is available by calling the Straight Talk Line at 805-606-VAND (8263).  Launch day and time is released three to five days in advance and is available on the hotline during that timeframe.   Beyond that, only the month and year of the next planned launch will be posted."
I called the number & it just says that "Base operations are currently normal." I assume that if the launch date is still on the 5th the message will change on Sep 1, 2 or 3.

Nope, the NET is September 5th

Visited SpaceX's factory. They're still aiming for NET Sept 5th. I'm guessing they'll also conduct a hot fire at SLC-4 sometime in the week or so leading up to launch.

Quick question: How often are the launch opportunities for CASSIOPE (300 x 1500 km, 80 inclination orbit with a period of approximately 103 minutes) from VAFB?

Depends if they are trying to phase the orbit with something, or attempting a sun synchronous orbit.

If being phased with something (Like ISS missions), it can vary.
If sun synchronous, once a day.
Otherwise, unless constrained by the sun angle there are no constraints.

I don't think the listed orbit is sun synchronous so they mostly likely they only have range constraints.

4 weeks away from the proposed launch date. This is about the time we find out how serious they were about 9/5/2013.

We should start seeing roll-outs if they're going to launch in a month.

Which they're not, so we won't, IMO.  ;)

But meanwhile, maybe someone can start a new thread in which we offer guesses as to launch date. I'm still with Jim at NET Nov.
