I'm with Gongora here. 5400kg vs 5300kg for SES-10, so I would be surprised if SpaceX didn't at least attempt an ASDS recovery.

Link below says 5200 kg, so looks like ASDS for sure.http://forum.nasaspaceflight.com/index.php?topic=43728.msg1725004#msg1725004
Thanks to all for the replies... My thinking though... is S1#1031 is an almost year old block ?3? stage...yes?SO... while putting Ti fins on it and trying to burn it down on an ASDS try makes some sense...It's just as likely to be surplus and headed for scrap as the Block 5's start crowding the barns...I guess we will find out soon enough...

The satellite was already there, and the press release just is late, or...2. SpaceX+SES have gotten much faster at integration than the SpaceX payload guide suggests, or...3. October 2 isn't realistic.Anyone have any idea which?
[Spaceflight Now] Launch operators expect minimal delays from Hurricane IrmaQuoteSES officials said the SES 11/EchoStar 105 satellite weathered the storm without damage inside a SpaceX-owned clean room in a hangar near pad 40. If ground crews can resume work on the satellite within a few days, the payload could still be ready for liftoff in early October.

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
There's a distinct possibility that SES required an expendable full performance launch for this launch.I'd say its 50/50 between ASDS recovery and expendable for full performance.

Re-posting some information re: time-proximate launches, originally from the TDRS-M thread.Thank you again to Jim.***48 hours or less to re-configure the Eastern range.Launches on October 5 and 7, both from KSC/Canaveral, are possible.Re: TDRSS use/possible conflict of use as part of launch ops.Atlas V and Delta IV use TDRSS; Falcon 9 does not.Quote from: Jim on 07/25/2017 09:40 pmQuote from: zubenelgenubi on 07/25/2017 09:11 pmNSF experts, please correct if I'm wrong:1. Currently, it takes approximately 3 days to reconfigure the launch range between Canaveral/KSC launches. Correct?2. Some, but not all United States launches use TDRSS during launch. Atlas V/Delta IV: yes; Falcon 9: no?***3. Launching TDRS-M from Canaveral on 8/10, followed by NROL-42 from Vandenberg, both on Atlas V's, is eminently do-able, yes?4. Launching NROL-42 on Atlas V, from Vandenberg on 8/14, followed by launching Dragon, on Falcon 9, from KSC later on the same day--also possible? No interference between the launch assets?5.

Since it's only a few days until flight, have we gotten any definitive word on whether SES-11 is going to be an ASDS recovery or full expendable?
Quote from: obi-wan on 10/04/2017 02:20 amSince it's only a few days until flight, have we gotten any definitive word on whether SES-11 is going to be an ASDS recovery or full expendable?It should be ASDS based on the mass (5200kg), and the FCC permit we think corresponds to this flight has ASDS landing. It's a similar mass to SES-10.

And FWIW, per Musk's 48 hours, the current schedule actually points to sub-36 hour back-to-back landings if schedules hold. Weather for the rest of the week at KSC is looking rainy and somewhat stormy, so upper level winds may be a bit rowdy. We'll see.
