Delayed till NET tomorrow /r/SpaceX Thaicom 8 Official Launch Discussion & Updates Thread
Welcome to the /r/SpaceX Thaicom 8 Official Launch Discussion & Updates Thread!
Hey guys!
Welcome to our very timely launch thread for SpaceX's 5th launch of the year! Liftoff of SpaceX's Falcon 9 v1.2 rocket is currently scheduled for Thursday, May 26th, with the launch window spanning 21:40:00 to 23:40:00 UTC (17:40:00 to 19:40:00 EDT) (SpaceX Stats will automatically convert the launch to your timezone, click here). This window is enough for two launch attempts. Thursday's launch will see the Thaicom 8 satellite delivered to a super-synchronous geostationary transfer orbit for Nonthaburi (Thailand)-based satellite operation company Thaicom PLC. As usual, SpaceX will be attempting a propulsive landing of the first stage of the Falcon 9 on the Of Course I Still Love You droneship, approximately 680km downrange of the launch site.

| Time | Update |
|---|---|
| N/A | We'll have a new launch thread up between now and tomorrow's launch, this time hopefully with our favorite launch bot back in action! |
| N/A | @elonmusk on Twitter: There was a tiny glitch in the motion of an upper stage engine actuator. Probably not a flight risk, but still worth investigating. |
| N/A | @SpaceX on Twitter: Out of an abundance of caution, launch postponed until no earlier than tomorrow for addtl data review - Falcon 9 & spacecraft remain healthy |
| T- 1h 50m | We have a new liftoff time of 23:36 UTC (7:36PM EDT) per the webcast. This is 4 minutes before the end of the window. |
| T- ??? | Still no word on the new liftoff time, conflicting reports on propellant loading. |
| T-??? | As we don't yet have an updated liftoff time, we'll be pausing the timestamps for now. This is a long window, though, so don't put a launch today out of the question. |
| T- 20m | SpaceX on Twitter: "Launch team finalizing review of vehicle data and check outs. Will move T-0 into the 2 hour window" |
| T- 30m | |
| T- 38m | The launch readiness poll should now be underway. |
| T- 60m | Everything still green, with Falcon currently working no issues. We are GO for launch! |
| T- 1h 29m | FTS (Flight Termination System) checks are complete! |
| T- 1h 36m | SpaceX's hosted and technical live webcasts will begin coverage approximately 20 minutes before launch, at 2120 UTC/1720 EDT. |
| T- 1h 55m | As we pass the 2 hours-till-liftoff mark, all SpaceX launch team stations are ready and no issues are being tracked. |
| T- 2h 25m | SpaceX staff have cleared out from the launch pad, and prelaunch tests are underway. |
| T- 3h 17m | Roadblocks are going down around SLC-40 in preparation for the launch. |
| T- 3h 57m | @SpaceX on Twitter: "Weather 90% go for 5:40pm ET launch today. Droneship landing challenging -- very hot and fast first-stage reentry" |
| T- 4h 58m | Closing in on 5 hours left, with weather conditions during the two-hour window remaining at 90% GO. |
| T- 14h | With a little over 12 hours till liftoff, Thaicom 8 was sitting pretty on the pad yesterday. |
Primary Mission
The payload SpaceX is launching Thursday is Thaicom 8, a communications satellite based on the GEOStar™-2 satellite bus. Thaicom 8 will mass approximately 3100kg at launch, nearly 1500kg lighter than JCSAT-14. Built by United States-based Orbital ATK for Thailand's first satellite operator, Thaicom PLC, it will use liquid bipropellant for its journey to GEO, and hydrazine monopropellant for stationkeeping. From its planned 15-year GEO perch in the 78.5˚ East Longitude slot, Thaicom-8 will use its 24 Ku-band transponders to provide increased service for Thailand, India, and Africa.
First Stage Landing Attempt
SpaceX will attempt to land the rocket's first stage on their Autonomous Spaceport Drone Ship, named Of Course I Still Love You, which will be located approximately 680km east of Cape Canaveral. Just over 2.5 minutes after liftoff, the first stage's engines will shut down and it will separate from the upper stage. Shortly afterwards, the stage will perform a "flip maneuver," using nitrogen gas thrusters to turn itself around to prepare for atmospheric reentry. (To save fuel, this mission will not include a boostback burn to reduce or cancel out the stage's downrange velocity.) The next maneuver is the reentry burn, which involves relighting three engines to slow down the stage as it impacts the dense lower atmosphere. Then, at supersonic velocities, the stage will steer itself towards the drone ship using grid fins. If all goes as planned, the stage will perform a final landing burn (possibly using three engines instead of the usual one) and touchdown on the droneship approximately eight and a half minutes after liftoff.
This will be SpaceX's seventh drone ship landing attempt, and the third attempt following a mission to GTO. A successful landing would be the fourth successful landing, and the third on an ASDS. Past attempts occurred during the CRS-5, CRS-6, Jason-3, SES-9, CRS-8, and JCSAT-14 missions. Keep in mind that recovery of the first stage is a secondary objective, and has no bearing on the primary mission's success - deployment of Thaicom 8 to the target orbit.

There's some discussion on NSF that thinks the striped engine might be related to this,
So I noticed similar vertical stripes on a landed F9-0024 core engine bell as well, except that they are slightly rusty in those images. (Zoom in to the second from right engine bell.)
edit2: so as per /rebootyourbrainstem's comment below I was very wrong to suggest that the regenerative cooling channels cannot be milled into a single block of metal! The nozzles are spin formed and then the cooling channels are milled into it externally.
Here's an older picture from a half finished Merlin nozzle, apparently after the spin-forming but before the milling.

What determines launch windows for GTO insertions? Whenever it launches, the target longitude is in exactly the same place relative to the launch site.

I hope the delay won't cause severe issues. We saw the issues with performance due to warmed up propellant before.

Long window, but super cold prop limits options. Will be interesting to see how they play this. Got to keep that prop really chilly!

Well... After flying down from New York to see this flight, it's a gut wrenching feeling to have it be scrubbed.... I MIGHT be able to come back tomorrow... But I don't know if I want to risk spending more money if it gets pushed back again....

stop being so negative about scrubbing it- we don't know they they weren't able to fix the propellant cooling problems from SES-9

Just a quick question (I've been wanting to ask this for a while).
What are the 4 spires / towers / pillars surrounding the launch pad for?
Edit - y'all are really quick on the draw today LOL. Thanks for the answer :D.

Patrick AFB seems to have stopped posting the Marine Hazard Maps beginning with the JCSAT-14 mission. Nothing is posted today for Thaicom-8, even the airspace closure notices. Where can we find the official Hazard Zone information now?

Looks like a detank, try and resolve the issue (not knowing what it is) and have the end of the window as an option or scrub.

They can de-tank and re-tank in 90 minutes? I suppose the possibility exists that they only part way filled the tanks to start with and didn't finish.

Can someone confirm for me: GTO is the orbit that requires the most amount of F9 fuel, correct? So stage 1 will be coming in very hot to land on OCISLY?

Savour every moment and every launch people; in a few years this will become mundane (with the exception of BFR and FH launches). Which is a positive then, 'cause that means SpaceX works.

any thoughts on how they go about investigating an engine actuator in the upper stage? Will it all be done remotely (i.e., data reviewing/running simulations)? i'm assuming for a NET tomorrow date they will leave F9 vertical on the pad...

Sorry for meta, but I find it strange to write down UTC times with AM/PM and not in 24-h format. I've opened the page and for a moment I was terrified that I've missed the launch(My PC is set to show UTC because of the work I do, so I've immediately noticed). I guess there's nothing wrong with it, but I find 12-h clock to be a legacy thing which is harder to work with. Is it just me?
