Thales Alenia Space to build Koreasat-7 and Koreasat-5A satellites
Quote
Cannes, May 12th, 2014 – Thales Alenia Space announced today that it has signed a contract with the Korean satellite service operator KT Sat, subsidiary of KT Corporation, to build two telecommunications satellites, Koreasat-7 and Koreasat-5A, winning the contract against an international field of competitors. The two satellites will provide Internet access, multimedia, broadcasting and fixed communications services.

As program prime contractor, Thales Alenia Space is in charge of the design, production, testing and On Ground Delivery (OGD) of the satellites. It will also take charge of the launch campaigns, the launch and early operations phase (LEOP)  and in-orbit tests (IOT).

Built on the Upgraded Spacebus 4000B2 platform from Thales Alenia Space, Koreasat-7 will be fitted with Ku-band transponders and Ka-band transponders. Koreasat-5A will carry Ku-band transponders. Koreasat-7's coverage zone encompasses Korea, the Philippines, Indonesia and India, while Koreasat-5A will cover Korea, Japan, Indochina and the Middle East. Each satellite will weigh about 3,500 kg at launch and will offer payload power of about 7 kW. Koreasat-7 will be positioned at 116° East and Koreasat-5A at 113° East.

"I would like to express my warm thanks to KT Sat for choosing us to build these two new telecommunications satellites," said Jean-Loïc Galle, President and CEO of Thales Alenia Space. "KT Sat is a long-standing customer, for whom we already built the Koreasat-5 and Koreasat-6 satellites. Through this new contract, we are delighted to support the development of large-scale space programs in South Korea, and in Asia in general."

Koreasat 5A and 7 telecom satellites to include the largest 3D printed spacecraft parts ever made in Europe
Quote
Cannes, October 12, 2015 – The Koreasat 5A and Koreasat 7 telecommunications satellites currently under construction by Thales Alenia Space will include the largest spacecraft parts ever made in Europe using a 3D printing technique called the “powder bed additive manufacturing process”. Measuring some 45cm by 40cm by 21cm, these telemetry and command antenna supports are made of aluminum. The parts for the two satellites are identical and were made in the same batch by the same machine.

Thales Alenia Space uses the Concept Laser Xline 1000R 3D printer, the largest laser beam melting machine in Europe,  belonging to Poly-Shape, a French company and partner of Thales Alenia Space.

These two parts, featuring an innovative bio-design, have just passed their vibration acceptance tests, demonstrating perfectly reproducible dynamic behavior. Using 3D printing technology on this type of part offers a number of advantages, including 22% weight savings, a decrease in the production schedule of around one or two months, about 30% cost savings, and higher performance.

An antenna support of this type is already in orbit since April 2015 on the TurkmenAlem satellite also built by Thales Alenia Space.

My guess is this is now August after CRS-12. There was some slip since February of getting 39A active and then the NROLl two week slip. That should be enough to push this a month given a 2 week launch cadence.

There is an outside chance that this is the first flight back at SLC-40 if 40 is operational by the end of August.

[SpaceNews] South Korea’s KT Sat wins Mongolian customer for Koreasat-5A

KT Sat announced June 14 that DDish TV, Mongolia’s sole direct-to-home television broadcaster, signed a multi-transponder lease for Koreasat-5A, a Ku-band satellite from Thales Alenia Space expected to launch on a SpaceX Falcon 9 rocket by year’s end.

The manifest indicates that there are plenty of launch slots in late summer into fall. So is this payload gated at the moment?  Maybe that's part of how the X-37B got an August launch?

1. Plenty of launch slots?  Only if you think SpaceX is ready to fly 3+ times a month indefinitely.  They have enough payloads on the manifest for 5 flights every 2 months, which would get them to around 24 flights for the year.
2. X-37B could have gotten an August launch slot a long time ago and we've never really gotten a firm date for Koreasat 5A.

That's more a consequence of us just not knowing exactly what the lineup will be more than any indication of payload readiness.  I don't think we can make any reliable deductions yet.
Shouldn't reality posts be in "Advanced concepts"?  --Nomadd

I found an image of Koreasat-5A on the KT Sat web site and attached it to the top post in the thread.  It is a bit higher resolution than they normally release  :)  The original png file from their site was 46MB, I saved it as a slightly compressed jpg to get the size down a little.  If you want to get the original it's at https://www.ktsat.net/newsroom/press-kit/.

10 days (Sept. 29) to SpaceX Falcon 9 (SES-11) Static Fire...at 39A. Oct. 2 launch, then all hands on deck to prep 39A TEL for Falcon Heavy.

You know I dare not call 40 until I see it on a schedule :)

Is there anything more definitive about Koreasat 5A being SLC-40?

Edit: Answer: Increasingly likely to be LC39A per link in following post

SpaceX sets Oct. 7 & 9 launch dates for next two Falcon 9 flights from East and West Coasts. Koreasat 5A in late Oct. confirmed from pad 39A

It's based on this e-mail that I completely missed earlier :)

>SpaceX Opens Media Accreditation for Koreasat-5A Mission


HAWTHORNE, Calif. – Sep. 26, 2017. Media accreditation is now open for SpaceX's Koreasat-5A mission from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. The launch is targeted for no earlier than late October.

A SpaceX Falcon 9 will deliver Koreasat-5A, a commercial communications satellite for KT SAT, to a geostationary transfer orbit (GTO).


More details on the mission and pre-launch media activities will be made available on a date closer to launch. <>

Maybe they also put it to LC-39A because "Koreasat" - easier to get Korean delegates on site when you don't need to get them Air Force clearances and stuff...

Huh? Why would there be a special problem for South Koreans? The Republic of China (aka Taiwan) representatives had no obvious problem to get into Vandenberg AFB for the launch of FORMOSAT-5.

Or did you mistake the home of Samsung for the home of kjulat?

You want to be inspired by things. You want to wake up in the morning and think the future is going to be great. That's what being a spacefaring civilization is all about. It's about believing in the future and believing the future will be better than the past. And I can't think of anything more exciting than being out there among the stars.

No.

There has been general issues (basically, slower processing) as referenced by, if I recall right, SES. Basically it is harder to get foreigners cleared for LC-40 as it resides in Air Force base.

But I guess in this case the main driver is just "LC-40 not yet ready" and any potential shorter accreditation timelines are just a side benefit.

Not true.  In fact, it's harder to get foreign media accredited for 39A missions that aren't NASA flights... so much so that SpaceX has outright told foreign media for some 39A missions that foreign media aren't allowed.

I was not referring to press, I was referring to the staff of the party that is paying for the launch and handling the payload.

Online Chris Bergin

Per L2, this mission is "Range Approved" by the Eastern Range for 39A, with a launch window opening at 15:34 Eastern, running through to 17:58 on October 30.

The Static Fire has been placed in the schedule for October 26.

Will create an update only thread today.
