How about this, SpaceX launches regardless. Can launch those two payloads and work on Cots 2 goals etc. Do as many Cots 2 or 3 that can be done. Cots 3 cannot be accomplished without berthing, that is the goal. SpaceX is being wise to wait for the crew, no use wasting a spacecraft on an incomplete mission.

So, the software upgrade might be an issue. I always assumed they could upload it. But they stated that it was a critical issue.That relates to Service Module (SM) vers. 8.05, and is not related to the Dragon berthing.You are right. According to this article (is it yours?) there's the need to do the X2_R10 and X2_R11 upgrade to the ISS software, and only then the SSRMS MSS 7.1 upgrade to be able to berth the Dragon. Did I got it right?Since this was part of Expedition 29, I understand that none of this has been performed. If the ISS has to do with a reduced crew until Soyuz TMA-03M docks, I think they will have little time to do the upgrade. Specially, in such a critical time were there's the risk of having to leave the station on remote control.Yup, that is my article, and you are correct.

Delay is a consequence of the recent Soyuz failure and the time it will take to get it flying again, and rotate ISS crews. #WSBWEven odds this is Gwynne pawning off SpaceX delays on NASA. Groan. It's no different than any other government contractor, space or not.

SpaceX is being wise to wait for the crew, no use wasting a spacecraft on an incomplete mission.I disagree, SpaceX has alot of bugs to work out and prob will find more after another launch. So the only way to get "experience" is to get some launches done.Experience is the best promotion.
So to sum this up we have 3 different potential delay mechanisms at work:1) ISS software delays2) Soyuz failure moving everything to the right3) SpaceX own development delaysDid I get that right?
Among the SpaceX delays, on an Orbital thread Antares mentioned that SpaceX had failed at some mission simulation, and would have to come back in December. I have seen no other mention of this.
That would set back COTS-2/3 quite a bit, assuming they aren't already postponed by by NASA's SSRMS software issues.Any confirmation out there or further information?

I don't consider contractors talking about each other to be credible without second-sourcing it. The amount of false noise that has come out of ATK in the last 5 years about Ares alternatives is pathetic.
We are scheduled for JT4 in November. We don't know what happened with SpaceX's JT4, I believe they had to stop it and will be back in December.

We don't know what happened with SpaceX's JT4, I believe they had to stop it and will be back in December.So it is not definitive, he admits it is speculation.(Joint Test 4) JT4 is not really a software test. It is a procedures test that involves running software but also includes ISS on orbit crew participation, basically a “dry run” for the rendezvous and berthing to iron out communications and any procedural problems. The testing was scheduled for early Sept as per the Aug 2 NASA briefing http://www.nasa.gov/pdf/580728main_5%20-%20Suffredini%20NAC%20August%202%202011_508.pdf after Progress 44. NASA could have halted the test and rescheduled it tentatively in Dec after the crisis caused by Progress 44 is over. This movement to the right for SpaceX also means the JT4 for Orbital which also includes ISS on orbit crew participation which was scheduled for Nov will probably move to Jan.Orbital’s statement was only that SpaceX for some reason in late Aug/early Sept was not able to complete JT4. Duh! ISS crew schedules would have been swept clear of all lower priority tasks. A dry run is definitely a lower priority task for ISS right now. They could have attempted it anyways but ran into some sort of difficulty which may or may not have been a SpaceX responsibility. With crew time in short supply a difficulty with executing the test, which under normal circumstances could possibly have been corrected so the test could complete, would cause a test termination under the new circumstances.If NASA has really scheduled this “dry run” JT4 until after a full crew compliment is onboard ISS then the COTS 2/3 probably will move into late Dec at the earliest, most likely Jan.
I assume this "dry run" would have been performed with the actual ISS crew that will be performing the actual rendezvous and berthing operations. Even without the Progress issue, those guys wouldn't have been on orbit yet, would they ? I thought this was a test using ground simulators. At least that was my initial impression after reading the Orbital thread.
Didn't know SpaceX had lots of bugs to work out. Where does this come from or is this purely speculative like so much other stuff here? Bugs implies problems with things not working as they're designed, not ongoing development and testing which I'm sure SpaceX is still undertaking.

All complex systems contain bugs, and that includes mature systems that have been through a lot of testing and in use for years (ref the recent Soyuz launcher failure after decades of operation).cheers, Martin
Do you think SpaceX updates the public on testing etc on a consistent enough basis? If you check their site, the last post was made in early August. Surely given the situation with the Russian Progress vehicle and production halt, you'd hope that SpaceX would have a view on how it affects them, and would thus update the public?It just seems like companies like Virgin and SpaceX tend go quiet for months at a time (from a publicity standpoint) then resurface in the news with a seemingly random update.
{snip}Given the frustration of the space industry that the public have grown callous to space-flight, surely every effort should be made by companies like SpaceX to re-popularise space-flight through relentless PR?
