Successful launch on June 4, 2018 at 12:45am EDT (0445 UTC) on Falcon 9 (reused booster 1040.2) from SLC-40, early in the 0029-0429L launch window.  Booster was expended.

   L2 SpaceX Section




SES-12 is a very large all-electric satellite with 19kw of electric power combining both Ku band widebeam transponders for DTH broadcasting and Ku/Ka band spot beams for HTS broadband applications.  It has a a total of 68 Ku band and 8 Ka band transponders.  The HTS payload will use 70 Ku band and 11 Ka band spot beams to provide 14GHz of capacity that can be configured with a Digital Transparent Processor (DTP), which provides increased flexibility as well as increased anti-jamming capability.

I've seen several masses given for SES-12, the most recent being 5400kg.  That's huge for a sat with all electric propulsion.

Launching May 24, 2018 at 12:29am EDT (0429 UTC) on Falcon 9 (reused booster, maybe 1040.2?) from SLC-40.  Booster will be expended.

This article by Chris Gebhardt says it is B1040.2.

https://www.nasaspaceflight.com/2018/04/spacexs-may-manifest-takes-shape-block-5-debut/

"One day after Iridium NEXT-6/GRACE-FO’s launch, SpaceX will be back in action in Florida with the Static Fire of core B1040.2."

"This time, the core will loft the SES-12 communications satellite for the SES corporation of Luxembourg to service the Middle East and Asia-Pacific region."

"Following a successful Static Fire, core B1040.2 and its second stage will be mated with its payload and prepared for launch on NET 24 May 2018 in a 58 minute window extending from 00:29-01:27 EDT (04:29-05:27 UTC) from SLC-40 at the Cape Canaveral Air Force Station."

[Spaceflight Now] New target dates set for next two Falcon 9 launches
Quote
On that mission, which an SES official said is currently scheduled for no earlier than May 31, SpaceX will haul the Airbus-built SES 12 communications satellite toward a perch in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.

Let's see what happens here because the Range is supposed to be closed from 29 May - 8 June for scheduled down period maintenance.

https://www.nasaspaceflight.com/2018/04/spacexs-may-manifest-takes-shape-block-5-debut/

"The Eastern Range in Florida will close on 29 May for a scheduled 11 day period of maintenance and upkeep.  These planned Range down periods are communicated well in advanced to all Range customers and are vital to ensuring reliable Range functionality.

The Range will reopen on 9 June for normal launch operations."

Venting observed. Via SFN, not me. All my pals have clocked off and gone home! ;D

Bill's working overtime:

@cbs_spacenews

F9/SES: We're standing by for a presumed Falcon 9 first stage hot fire test at the Cape Canaveral Air Force Station; the vehicle is perched atop pad 40, loaded with propellant and venting as usual in the later stages of a countdown

Offline Chris Bergin

Done!

Via Bill:
F9/SES: Hot fire test conducted at 9:30pm EDT; we'll now wait for an update from SpaceX to let us know when they'll be targeting launch for the SES-12 communications satellite (believed to be no earlier than 4:29am on 5/31)

Now for the SpaceX tweet, as per usual, that we need to confirm a good test via the Quick Look Review.

SpaceX:

Static fire test of Falcon 9 complete—targeting May 31 launch of SES-12 from Pad 40 in Florida.

M1465 SES-12 Launch Hazard Areas based on NOTAMs.

Location of Area B (orange) for booster splashdown/fairing landing is now unusually northern compared to other GTO missions.
