I assume that Imam Khomeini Space Center is the site formerly known as Semnan.

I suppose that it is a specific area of Semnan, but I'am not sure about this.

Report: Iran successfully launches satellite-carrying rocket.

Until now there is no reference to a satellite only to "a satellite-carrying rocket."

IKSLC opens with test launching of Simorgh satellite carrier into space.

Still no reference to a satellite on this launch.

If I have understood correctly, it was the second suborbital Simorgh launch.

The published launch time (09:30 UTC) is close to the published launch time (09:33 UTC) of Simorgh rocket on April 19, 2016. If it was the second Simorgh launch then why Iran said that "the launch signals official inauguration of Imam Khomeini Space Center"? I think that it means that the first launch was a failure.

Or the launch in April 2016 was not Simorgh.

Any ideas on the cause of the red colored plume coming out of the interstage section right at liftoff?   Wouldn't that typically indicate N204?  But coming from the interstage?  I've never seen that on Soyuz or Proton.

My guess is that N2O4 is a pressurizing gas for the S1/S2,  & excess is being vented as the Simorgh's systems start flight?

Iran claims the launch as being successful.

http://www.presstv.ir/Detail/2017/07/27/529852/Iran-successfully-tests-Simorgh-satellite-carrier

Videos attached. I've corrected the aspect ratio of the second video.

This report says the vehicle did not put a satellite into orbit. Bing translation.

"Shahrabi said in this regard: Although the launch yesterday, did not put a satellite in orbit but in the distant future a system of 40 to 160 to satellite remote sensing, telecommunications and positioning in the circuit."

According to news reports today, Pentagon Officials have declared this a catastrophic failure; nothing achieved orbit, so no TLEs were published by 18SPCS.

Judging by the speed at which it jumped off the pas it must have had a pretty high t/w, might just indicate dummy or unfueled upper stages.

I know I'm slightly out of subject, but Ed Kyle can you indicate us why you do not count this launch attempt as an orbital attempt in spacelaunchreport?

Now we know this was, with a high degree of certainty, a failure. But the iranian government clearly indicated it was an orbital launch.
I would probably treat it like the rocket lab first shot, don't you think?

Insufficient information.  I disagree with the assertion that "the Iranian government clearly indicated ..."  See up-thread discussion about how it was called an "orbital capable" launch vehicle, but no mention of a specific payload, etc, or even that it was a real orbital attempt.  I'll add it later if better information is provided one day.  Too much disinformation from both inside and outside Iran right now.  If it was an orbital attempt, it failed as claimed by U.S. sources.  If not, it may or may not have been a suborbital test failure.

 - Ed Kyle

Very valid reason indeed.
My own view on the matter (not that it should weight for something) is that it was the Sharif orbital remote sensing satellite, presented earlier in the year with Amirkabir and Nahid sats. Knowing this was a failure, state has declared it was a success for the public but didn't mention the sat as it was destroyed.
We probably won't know more before a few months when they will speak about the next launch attempt.

Iran has never release footage of a failed orbital launch so far. This is a strong hint, that this launch was not a failure. Therefore IMHO this was a successful suborbital launch. Note, that in translations from Farsi, there was often a mixup between "space" and "orbital".

Given the fact iran released pictures and video of this launch it is probable that this was in fact a suborbital launch. Also cant help but notice the remarkable design similarities this rocket has with NK's Unha-2 rocket.

That shows the second stage being integrated horizontally, but the other image shows the first stage being lifted vertically, with presumably the second stage being integrated vertically.

Because if what they were reporting about *this* event wasn't accurate, I wouldn't have sourced it.  I have already contacted the author with corrections to a misstatement made by their source that was used in 3 or 4 related articles.  They will publish a correction.  It seems pretty foolish to dismiss the report out of hand simply because it came from the most widely trusted newsource in the country... you're letting politics spoil your objectivity.

Iran's July 2017 Simorgh failed due to a problem with the 2nd stage, which failed after 20s of powered flight (of planned 300s).
