Will kick this off by starting the list of known SpX-1 payloads (will update as more info becomes available).

Internal cargo:

Up:
-Student Spaceflight Experiments Program (SSEP) Mission 2 to ISS (via NanoRacks) - includes reflight of failed payloads from SSEP Mission 1. More info here and here.

Down:
-Urine Monitoring System (UMS) - launched on STS-135 but has encountered issues on-orbit. Will be returned to Eath for refurbishment and future re-launch.


External (trunk) cargo:

Up:
-None

Down:
-None

Thanks Chris and Pete. Great way to start off the CRS SpX-1 coverage.

I like the grouping of cargo items into the 'Up' and 'Down' categories, Pete. Reminds me of the shuttle manifests during ISS crew rotation flights! :)
Space launches attended:
Antares/Cygnus ORB-D1 Wallops Island, VA Sept 2013 | STS-123 KSC, FL March 2008 | SpaceShipOne Mojave, CA June 2004

Just a clarification in case anyone's wondering - naturally, trunk cargo listed under "down" will be items for disposal in the atmosphere, not return to base.

Try linking directly to anik's June 12 update rather than the first message in the thread.

We will know that Dragon CRS flights are "routine" when anik includes them twenty months in the future like ATV-5.  As it is, it is good to see "Dragon SpX-1" on his authoritative list.

Edit: Direct link to anik's June 21 update which has no changes to the CRS-1, as stated below

I see anik has a new schedule up as of yesterday & there are no changes in the dates for CRS-1. Do we have anything else official?

anik's latest update (June 25) indicates another slip to an October 5 launch. 

Now only 8 days margin before a conflict with the Soyuz TMA-06M launch.  ISTM that the discussion of NET launch dates are no longer relvant. Given the busy schedule at the ISS, both VVs and astronaut tasks, slips cannot be day by day.  Launches have to fit into the flow pattern, and the supplies are needed, although perhaps not critically.

Is there any clue as to the reason(s) for these recent delays?

FWIW, SpX-1 is far enough ahead that it's as likely to be a re-schedule than it is a slip.  ISS is a busy place for visiting vehicles and we know that two US crew are needed to berth the Dragon. All these requirements can shift the launch date around.  IMHO, it'll become a 'slip' only when we're within a month or less of the NET date.

FWIW, CRS specifies a series of narrowing delivery windows in days as a function of months before launch (by "mutual agreement"):
* ATP through L-13: 90 days
* L-13 through L-4: 30 days
* L-4 through L-2: 14 days
* L-2 through L-1: 4 days
* L-1 through Launch: 1 days

Can you interpret for us what this means?
Does it constrain launch to happen within 139 (=90+30+14+4+1) days from ATP?
What happens if they don't?
What happens if they have a launch scrub after L-1?

That mention of delivery windows was primarily in response to the discussion of a slip above.  I don't think "constrain" is quite the right word; presumably a delay outside those windows would be considered a slip.  I don't know of any penalties, other than maybe some relationship payment milestones, and of course there may be an impact to other activities and schedules.

The more it slippes, the less chance have thrid F9 to actually launch in 2012. It is not even about influence of previous launch on next. Thrid launch can and will slip to right on its own.
