any movement of material(s) from the delayed SpaceX flight being transferred to Cygnus?
 
I for one would be very interested in the inner working of NASA in shipments to the ISS.

Unlikely.  As this is a test flight for Orbital, NASA will probably do them the same courtesy as they did SpaceX and classify all cargo carried on the test flight as "non-critical" supplies.  Cargo on regular CRS delivery flights is classified as critical, however.  Thus any specific special hardware or cargo items (but not generic consumables like food and clothes) already scheduled for a ride in a CRS Dragon will already have the critical classification, making them unsuitable as cargo for this Cygnus test flight.

So will the "late load" capability be used for perishable items (fruit, vegies, etc.), or maybe some non-critical ISS item that will take this flight of opportunity ?

Unlikely IMO. The demo flight doesn't assume that the material will actually be delivered - there are acceptance gates to get through first -  and the timing is also uncertain due to all the approach and abort demonstrations that need to be done.
When I say "Jump!", you say "To which orbital inclination?"

How late in the flow is late-load for Cygnus? I imagine access must be harder than for Dragon because Cygnus is buttoned up inside the fairing.

Given that the launch date for ORB-D hasn't move a lot over the last few months, and that there are no more major orbit changes for the ISS over the next month or so, can someone help to calculate the approximate in-plane launch time on Sept. 14? (remember that all Antares/Cygnus launches go for the descending node)

(from the update thread)
12/08/13..............Orbital/Cygnus CRS-1 launch
12/11/13..............Orbital/Cygnus CRS-1 berthing (Harmony nadir)

Seems a tad aggressive... Lets hope they do not have to spend cycles digesting the 9/15/13 demo launch data, and can pull it off in less than three months! Though from previous Orbital posts it appears all the hardware for the next few flights is already on site.

What was Orbital's original prediction after the first flight for the demo?

For a new vehicle, 3 Antares launches in 2013 would be a nice flight rate. Have any new space companies achieved that rate?

We clearly need a ORB-1 Thread. I'll sort that out in the morning, per:

Launch date latest for CRS-3/SpX-3 - now 2014, with ORB-1 going in December.

Article by Pete Harding (with the meat) and the dates covered by yours truly.

That's UTC so the launch time is 12:08 pm EDT on Sept. 15. Prepare for your cameras and cars for the trip to Wallops!  :D

We clearly need a ORB-1 Thread.

And ORB-1 Party Thread. A name suggestion in the hopes that it will make it in December:

With Cygnus ORB-D now to depart Earth 2 days later than planned & Atlas V/AEHF-3 flying a week earlier, the two launches are now less than 16 hours apart. Anyone here willing to try the ultimate NSF geek mission of catching both launches at once?  ;)

(shouldn't be too difficult to drive from Wallops to DC/Hampton Roads area and catch a flight to Orlando that evening.....  ::))

Maybe it's even worthy to try to catch all 5 US launches over the next 3 weeks, although that obviously requires loads of free holiday, bucks, buck rogers, prayers that all 5 goes on time and a transcon flight.  ;D

Actually, it is possible to drive it in that time frame...
