Apparently this satellite is known under the name of  NSSC (National System of Satellite Communications)

Indeed, unexpected.

That will be 20th item in SpaceX launch manifest between now and end of 2014. Best of luck to Turkmens but I wouldn't hold my breath for an actual launch in stated time.

Agreed, R7. Although to win a contract off a Chinese launch (which must be cheap) is very unexpected, for any one!

Probably has at least something to do with this:

RIP ITAR-free: Thales decision to launch Turkmen telecom sat on SpaceX Falcon 9 & not Chinese vehicle signals end of ITAR-free line, for now

So it's the Chinese being burnt by ITAR again: changes in the ITAR parts list means that some of the parts used on the satellite are no longer ITAR-free.

Interestingly the launch contract has a clause that requires SpaceX to demonstrate GTO launch capability with the F9 v1.1 by the end of 2013, or else Thales Alenia Space can terminate the contract and send this satellite to Arianespace/ILS/Sea Launch. Time is now rather tight since the launch SES-8 is now NET October......  ::)

This is interesting.  I thought I read somewhere where SpaceX stated that they couldn't take more orders as their manifest was full for the next couple of years.  Apparently this was incorrect.

Is there any theoretical possibility that something that pre-existed on the manifest could share a ride with the TurkmenistanSat? NSPO/Taiwan payload is probably quite small, it was previously listed to use Falcon-1e.

Given that it is going to GTO and weighs 4.5 tonnes..... probably none.  ;)

How come an European built sattelite for Turkmenistan falls under US ITAR?
Does it contain any American hardware?

Is there anyone here who believes that this satellite will launch on or before Q4 2014 ends?

I think it's doubtfull, but we really don't know what the operational tempo of the Falcon 9 is going to be once the kinks are worked out.

True, they're pretty much stockpiling M1D's now from what I've heard. With those being produced at a good clip, they just need to make the stages fast enough.

You can get an estimate of tempo (for a launch site) by looking at the Falcon 9 User's Guide in Section 5.4 http://www.spacex.com/Falcon9UsersGuide_2009.pdf
in which it states payloads can arrive three weeks in advance of flight and is required to be present by two weeks before flight for integration and test.  Taking more than 3 weeks seems to be an "additional charge" service. The diagram of the building in that document indicates it can deal with one rocket at a time.

This implies a tempo (presuming one payload at a time) of possibly as short as around 3 weeks, or 17 flights/year.

And there are two launch sites, though they may not be interchangeable for particular payloads.

Ground facilities seem unlikely to be the bottleneck, unless there are a lot of problems testing full up tests on the pad.

I suspect production of flight hardware may be the initial bottleneck....

commerical spacecraft take 4-10 weeks to prepare for launch and that doesn't include the two weeks with Spacex

Jim,

Didn't you mention that the integration will happen within the SpaceX facility ? If that takes 4-10 weeks, how can the spacecraft arrive only 2 weeks before the scheduled launch ?

Maybe they mean the spacecraft has to be onsite and ready for integration with the LV 2 weeks before the launch date.
