yes thanks for the pix all, the DSP-23  apparently landed within 2 miles of its desired orbit, which is exceptional .  (and the DSP-23 was  needed since a past launch didnt "exactly" put one where it needed to be. Thanks to some great handling by NGC folks, it was still "usable") Pardon the mealy mouthed words, but I am trying to be as PC as possible.  :)

Does anyone know what longitude this will be placed at?

There are at least 30 large upper stage debris still being tracked following this launch.
There are said to have been released after the stage reached its temporary parking orbit (220km x 1575km).
A similar unplanned debris release happened during the previous Delta 4 launch in November 2006 when about 60 large debris were released  from the upper stage at an altitude of about 850 km.

Has anyone any idea on what could be the reason for this non nominal debris release?

"large" means a debris larger than 10cm.

Which part of the upper stage could be involved: engine, tanks , interfaces?

More interesting is which part can shed parts (twice) and not lead to a failed mission.

If you watch the movies (available on Spaceflightnow) you see some shedding from the RL10 nozzle.  My understanding is that these are strips of material from a reinforcing ring required for ascent, but not engine burn.

Can you please provide the link for the video?

Are you sure the scene you mentionned was shot after entering parking orbit  when the unplanned release occurred?

They don't appear to be on Spaceflightnow any more.  Ecliptic Enterprises provided the camera, and has a couple of movies on their web site.  Try this one, and look about 14 minutes into the video, on the right side of the nozzle, up through SECO1.  This was not after parking orbit, but close to entering the park orbit.

All of the Delta IV launches on that site show the same phenomenon of foil or tape-like debris coming off the second stage nozzle. Some of that looks like it satisfies the "over 10 cm" size requirement. I think they all do that.

It was an earlier launch - you can see the same thing, since it affects all Delta 4 vehicles.

I can see some parts ejected from the nozzle (specially during the Aug 28, 2003 launch at 5mn 48s into the flight when a kind of ring is ejected.). However no debris are tracked for this flight.

I still think that it might be something else for the Nov 2006 and Nov 2007 launches. It is reported that a "commission" is working on it...

Other than the two heavy flights, I thought the other cape Delta IV flights where to GTO not GSO, meaning any debris should have been in short lived orbits. Since the first heavy flight was a demo flight maybe the AF was looking more closely at the flight than the other GTO flights?
