Cool!
We of course have to wait for SpaceX to say anything (like they did with the 15 second firing, with the youtube video).
Edit: No usual word it was the the test we're waiting for, so we will have to wait a little longer for the big milestone.

Three minutes, is that the normal full duration of the test?

That should be close to fuel depletion of the stage. Are you wondering if this was shorter or longer than normal?

Yes, I was wondering if this was the normal firing duration that it was supposed to be. Hoping all went well!

Yes. The F9v1.1 first stage usually burns just short of 3 minutes (depending on margin for boostback/landing), and F9 FT should be very similar.

Question: What is the latest into the processing flow for this mission that SpaceX can go before they finalize the incident report from CRS-7? The more milestones they pass in the workflow (full duration static fire, for example) the more I wonder how they got this far without already having a finished incident report.
It's not possible that the report has been finalized but not released publicly is it? Could SpaceX wait as long as the Launch Readiness Review to finalize everything?
I'm just trying to get a feel for when to expect the report in relation to the RTF NET launch date. Thanks.

I might be wrong here but, basically, isn't it the case that basically SpaceX can launch whenever they've got a slot on the range basically at the customer's risk so long as they satisfy range safety that the vehicle isn't a hazard to life? I'm thinking that NASA will want to see the SpX-CRS7 failure report before they use another Dragon for their cargo but it is basically up to the commercial customers if they want to risk using Falcon-9 FT.

SpaceX President Shotwell Oct 27 at CASBAA convention: Current target is early Dec for Falcon 9 v1.2 Full Thrust upgrade w/ Orbcomm sats.
Additionally, would I be right in saying that this means SpaceX views early December 2015 is the 'NLT' for this mission rather than the 'NET'?

No, that would be ridiculous.

No. Beyond what's already been stated, it's probably a bad idea to set NLTs for a return-to-flight mission
and a substantially upgraded version of the rocket. There'squite a bit of risk and additional stress that make it worthwhile for SpaceX to be extremely cautious, and NLTs can cause "go fever."

What other tests would they run that sounded like a hot fire?

If it was 3 minutes, it could have been a full-duration test on a subset (even one) of the nine engines. Speculation: In case they swapped out some component or engine after the 15-second test, and didn't want to remove the engine to the vertical single-engine test stand for a long run.

Many reasons for not concluding results of a test here. Sometimes you need to understand the results differently than expected, sometimes you might spot an opportunity for improvement. Just lots of things.
This is the time you look closely at things. And also examine past runs and flight history to tell the story of the propulsion system from how it operates alone.

Not sure. Remember, SpaceX isn't providing a running commentary on McGregor testing (they never have), so we're all using locals hearing rumbles, which we then go ask about and check.
Locals hear the rumble for the three minutes this time, but apparently it wasn't the test we're all waiting for as the milestone in RTF.
Because we were expecting the full duration test, a lot of people (myself included) assumed that "should" be (never said it "was") the test in question. When we check we usually get a thumbs up and eventually SpaceX give an official thumbs up (after checking the data....like the Static Fires at the Cape). None of it happened with this one, so it wasn't the test in question.
But it shouldn't be long now.

As a_langwich said, I was just answering the question with one possible explanation. It would have been more clear if I had quoted the question. I have no inside information on what is happening.

Discussion in that post suggests it was a single engine, 3 minute test and not the first stage static fire we are waiting for.

True could have been a stage 2 test. Reports indicate could be heard from very far away.
