New Dragon per NASA mission, but they are looking to sell used Dragon's to other customers. Have tested them when they've come back and they work fine.

I believe they also mentioned possibly re-using them for NASA missions.

Let's stick to updates, folks.

SpaceX are ready for the second operational mission.

Late load ops started - 24 hours prior to launch. L-8 hours for the last cargo.

(Lists the events for the ride uphill, but you all know that stuff )

Quick mission to berth, less than 24 hours.

Can go as low as 200x200nms if they have an engine issue.

Grapple bars in the trunk as the first unpressed cargo.

At this point in the briefing, Shotwell also stated that the grapple bars-to-trunk payload interface was designed and built by SpaceX, as well as the grapple bar "bundlers", which will stay on the ISS after Dragon departs.

Grapple fixtures are 273 kg.

Each or combined?
Does that include the hardware that will be left in the trunk?

Lots of images of the hot fire test were just uploaded. Here are a few.

Falcon 9 and Dragon rolled out from the hangar, looking pretty on the pad! Launch targeted tomorrow morning at 10:10AM ET / 7:10AM PT. Watch LIVE at www.spacex.com/webcast.

It sounded like she meant the 273 kg was the combined mass of the HRSGFs.

She also said packaging hardware in the trunk an extra 100kg.

All is "Go" for Friday Morning's Launch
Thu, 28 Feb 2013 10:51:00 PM UTC+0100

"We're about to launch and we're happy to be here," said Mike Suffredini, NASA program manager for International Space Station at Johnson Space Center, as he kicked off the Falcon 9 prelaunch press conference. "Quite a bit of work has been done by the SpaceX and ISS teams to get here. We've spent a few weeks getting the station ready."

Joel Tumbiolo, launch weather officer, 45th Weather Squadron at Cape Canaveral Air Force Station, reported that the weather still remains 80 percent favorable for the 10:10 a.m. EST liftoff. The only concern would be a slight chance of wind or cloud violations.

"Very excited to be back here. We're a launch company and we love to launch," said Gwynne Shotwell, president of SpaceX. "We're prepared to fly."

Tomorrow's launch coverage starts at 8:30 a.m. on NASA TV, www.nasa.gov/ntv and the NASA blog www.nasa.gov/spacex.

The mission is the second of 12 SpaceX flights contracted by NASA to resupply the International Space Station. It will mark the third trip by a Dragon capsule to the orbiting laboratory, following a demonstration flight in May 2012 and the first resupply mission in October 2012.

We tried to figure it out from the information in the video above your post.

Edit: starting at 29:40

Per Shotwell's comments (her "doing math in public" statement):
1050kg total up-mass (stated)
Would suggest:
677kg pressurized (published)
273kg HRSGFs (stated)
100kg support for HRSGF (stated/implied)

There appears to be some question as to whether the 273kg figure is inclusive, or whether there is an additional ~100kg for the hardware to attach the HRSGFs to the ISS (which Shotwell also suggested, altho hard to tell). If Shotwell's 1050kg total is correct, 273kg is inclusive.

Speculation beyond that is probably best discussed in the SpaceX Falcon 9/Dragon CRS SpX-2 MISSION GENERAL DISCUSSION thread.

Don't think these three photos from today have been posted yet.

And I think the Falcon 9 is now being rotated to the vertical position (from the video cams at http://countdown.ksc.nasa.gov/elv/).

Huge launch day article by William Graham.

I've got to set up the launch day thread (and there's no point opening it until the morning) so posting it here:

http://www.nasaspaceflight.com/2013/03/spacex-milestone-falcon9-launch-dragon-crs2/

Seriously, that's a lot of info, so get it retweeted and shared etc. No excuses.

Launch day thread is now on. Locked as a placeholder until the updates start arriving:

If 1050 is correct, 273 is *exclusive* of the attach h/w since 677+273+100 = 1050
