The next Falcon 9 launch is SES-8, SpaceX's first launch of a large geostationary communications satellite. SES-8 is currently scheduled for NET (no earlier than) October 23. That's only 3 weeks and 2 days out, though it may slip a bit.

SES-8 info

http://www.orbital.c...ications/SES-8/

SES-8, a hybrid Ku- and Ka-band spacecraft, is the sixth STAR™ satellite ordered by SES WORLD SKIES. The satellite is based on Orbital’s Enhanced STAR 2.4 bus, and will carry 24 active Ku-band transponders of 36 or 54 Mhz capacity switchable among 33 channels and two beams. Certain channels in each beam are cross-strapped to multiple frequency bands, enabling flexibility for new services. In the addition, the spacecraft features a Ka-band payload. The spacecraft will generate approximately five kilowatts of payload power and will feature two 2.5 x 2.7 meter super elliptical deployable reflectors and a 1.45 meter fixed, nadir antenna.

Performance:

Repeater: 24 active transponders with one group of 18-for-15 and one group of 12-for-9 TWTAs
TWTA Power: 120 W RF
Antennas: Two 2.5 x 2.7 m single shell super-elliptical deployable reflectors and one 1.45 m single shell fixed reflector

Stabilization: 3-axis stabilized
Launch Mass: 3,200 kg (7,055 lb.)
Mission Life: 15 years

question for you doc

will the shutdown of your governement have any effect on the launch of this mission ?

and of further mission for SPACEX and or other launch providers ?

 

 

SES: We'll wait for SpaceX details on non-reignition of Falcon 9 upper stage before shipping SES-8. Anyway Cape closed w/ govt shutdown...

Dunno. Pete de Selding is doing a Space News story on the ramifications for NASA etc. so he's probably going to be the best source short term. I can tell you that Sierra Nevada is locked out of NASA Dryden and therefore Dream Chaser's hangar.

Here is part of de Selding's SES-8 atticle-

The shutdown of the U.S. government has rendered moot the date of SES-8’s launch from Cape Canaveral Air Force Station, Fla. Feltes said no new launches are moving forward during the shutdown. SES-8’s manufacturer, Orbital Sciences Corp. of Dulles, Va., is weighing whether to send the satellite to Florida aboard a truck once SES has authorized its shipment to the spaceport.

There's apparently more to this.

It could be that shutdown will effect NASA projects like commercial crew (thus the Dream Chaser lockout) but the SpaceX commercial missions are NOT for NASA - they deal directly with the US Air Force who occupies and runs the range. The funding rules are different for the military since it is constitutionally mandated.

I say this because there are comments from.involved boat ties that the SES-8 spacecraft could ship to the Cape soon.

Very much developing.

Well, this is interesting.

Contrary to implications in the Space News report the SES-8 satellite HAS BEEN SHIPPED from Orbital Sciences to SpaceX's LC-40 pad. This shipping could only occur if SES gave the go-ahead, which implies confidence in a launch date from the range.

Checking the statements by the 45th Space Wing and Patrick AFB they are closing only a few services (commissary, library and donated goods center for airmen), only limiting hours at others. They plan to stay in business as much as possible.

It's in the news now as well that SES gave a green light to have SES-8 shipped to the Cape on October 2nd!

 

 

PARIS — Satellite fleet operator SES has authorized the shipment of its SES-8 satellite to Florida to prepare for the first fully commercial launch of a SpaceX Falcon 9 rocket despite the ongoing concerns of insurance officials that the Falcon 9 v1.1’s Sept. 29 demonstration flight did not meet the stated objectives.

Yup, and the F9 for Thaicom-6 is getting ready to ship. No lack of space - SpaceX has taken over a Delta II hangar.

F9-08 (Thaicom-6) first stage has left the building and is headed to McGregor for engine tests.

Hmm, that might be watchable for me... DST change comming up should push this to before midnight for me :)

 

Also, DocM. Could you please tell more about that Delta II hangar? Is it close to their launch complex? Will they ship approved stages there or also payloads? Etc :)

SpaceX took over Hangar AO at KSC in 2011 and put almost $8 million in refitting and upgrading it. Most recently it was used for the Delta II, but it's also where the Voyagers were prepped.

AO is large enough to process 2 Falcon 9's simultaneously, so with their main hangar at Launch Complex 40 (LC-40) they can now process 3 vehicles at a time. This is necessary in order to increase their launch rate.

In addition to Hangar AO and LC-40 they are also bidding for a long term lease of the giant pad at LC-39A and access to the Vehicle Assembly Building, both previously used for the Saturn V and Space Shuttle. This is adjacent to LC-39B, the Space Launch System pad.

LC-39A would be used for Falcon 9, Falcon Heavy, Falcon 9 / DragonRider (crew) and a future methane fueled SuperHeavy class launcher. Imagine a rocket more powerful than Saturn V with a half mile long blue flame.

They are also close to announcing a new private spaceport and large factory in Brownsville Texas at Boca Chica beach.

Sweet, didn't know about that hanger before. Tnx :)

 

Did know about the Pad 39A & Brownsville developments. To bad that the shutdown is now going to even further drag that GAO ruling on BO's protest :( About Brownsville, I had hoped SpaceX would have made it final already... but I guess they are waiting for the final version of the EIS by the FAA before announcing. Do they own enough plots of land yet to develop all desired structures?
