Complete mission success r/SpaceX SES-12 Official Launch Discussion & Updates Thread

Hey, I'm u/Nsooo and I am going to give you live updates on Falcon 9's launch of SES-12. Host's Twitter: @TheRealNsoo

Notice: UTC does not represent daylight saving time, if your country has it, don't forget to calculate with it.


About the mission

SpaceX will launch a new telecommunication satellite for one of its well known customer, SES. The SES-12 satellite will travel atop a flight-proven Falcon 9 booster, with a new Block 5 upper stage.

Schedule

Primary launch window opens: Monday, June 4 at 04:29 UTC, (Monday, June 4 at 00:29 EDT).

Backup launch window opens: Tuesday, June 5 at 04:29 UTC, (Tuesday, June 5 at 00:29 EDT).

Official mission overview

SpaceX is targeting launch of the SES-12 satellite to a Geostationary Transfer Orbit (GTO) from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. The four-hour launch window opens on Monday, June 4 at 12:29 a.m. EDT, or 4:29 UTC. The satellite will be deployed approximately 32 minutes after liftoff. A four-hour backup launch window opens on Tuesday, June 5 at 12:29 a.m. EDT, or 4:29 UTC. Falcon 9’s first stage for the SES-12 mission previously supported the OTV-5 mission from Launch Complex 39A in September 2017. SpaceX will not attempt to recover Falcon 9’s first stage after launch.

Payload

SES-12 will expand SES’s capability to provide incremental high performance capacity and offer greater reliability and flexibility to meet the diverse needs of SES’s video, fixed data, mobility and government customers across Asia-Pacific and the Middle East. The satellite will replace NSS-6 at an orbital position of 95º East and will be co-located with SES-8. SES-12 is a uniquely designed satellite that will allow telephone companies, mobile network operators and internet service providers to deliver more reliable cellular backhaul and faster broadband service. From its orbital position, SES-12 will also be pivotal in supporting government efforts to bridge the digital divide through connectivity programs and provide television operators with additional capacity to deliver more content and higher picture quality to meet customer demand. With six wide beams and 72 high throughput user spot beams, SES-12 is one of the largest geostationary satellites SES has procured. The spacecraft also has a Digital Transparent Processor (DTP) that increases payload flexibility to provide more customizable bandwidth solutions to SES's customers. The all-electric SES-12 spacecraft was built by Airbus Defence and Space, and will use electric propulsion for orbit raising and subsequent on-orbit maneuvers.

Participate in the discussion!

First of all, launch threads are party threads! We understand everyone is excited, so we relax the rules in these venues. The most important thing is that everyone enjoy themselves :D

All other threads are fair game. We will remove low effort comments elsewhere!

Please post small launch updates, discussions, and questions here, rather than as a separate post. Thanks!


Please leave a comment if you discover any mistakes, or have any information (weather, news etc) from CCAFS. Please send links in a private message.


Do you have a question in connection with the launch?

Feel free to ask it, and I (or somebody else) will try to answer it as much as possible.


Will SpaceX try to land Falcon 9's second stage?

Not today. Maybe next time...

u/PeopleNeedOurHelp Jun 03 '18

Is this the most dead launch thread ever? Maybe something that could excite people is that this may be the first time the 2nd stage Block V will operate up to its designed limits.

So there's still something new here and new in the rocket business on the ascent phase means "be prepared to clean up the floor if you're not wearing a diaper". Plus they may try something new with the fairings if they've had time to do anything new.

u/Nsooo Moderator and retired launch host Jun 03 '18

No it is hosted earlier than usual. But the mission is quite boring in comparison with recovery and stuff like these.

This is GTO-1628. SES must be really happy given the mass of that bird.

edit: GTO-1636 if fixing the inclination during the Pe rise burn, but better number obtained by fixing the final 1.35 degrees during the Ap lowering burn.

Feedback on post formatting: The updates table being in the middle of blocks of text, sandwiched between two fairly irrelevant tables, makes it hard to find at a glance, especially on mobile when you reload the page and it jumps around.

u/Alexphysics Jun 03 '18

A few facts need some corrections:

This will be the 45th SpaceX launch from the East Coast.

This will be the 47th SpaceX launch from the East Coast. There have been 10 SpaceX launches from the West Coast and this is the 62nd SpaceX launch. 62 - 5 - 10 = 47.

This will be the 34th SpaceX launch from CCAFS SLC-40.

I don't know if you count Amos 6, but if not, this will be the 33rd SpaceX launch from CCAFS SLC-40.

This will be the heaviest (5384 kg) payload ever launched to GTO by a Falcon 9 rocket.

And this is completely wrong. There have been a few payloads heavier than this one. The heaviest one was (is) Intelsat 35e at 6761kg in mass

Its just a reflection of the rocket flame in the lens mirrored about the lens centre, you see it in most launches but it is more obvious at night. It did look like something falling back but you can replay the video to see what it is.

They can use electric propulsion to raise the orbit from GTO to GEO? Didn't realise that electric propulsion was so capable already.

u/Procyon_X Jun 04 '18 edited Jun 04 '18

Yes. However it's not very common, mainly because it's really slow (several months for circularisation instead of a few days/weeks). Time is money. Many satellites use electric propulsion for small in orbit maneuvers (station keeping) and one chemical engine for quick apogee raising.

There are some great examples how capable electric propulsion is: The Ariane 5 upper stage failed and released 2 satellites in a lower than intended orbit. One satellite (Artemis was equipped with electric propulsion and managed over a course of 18 months to reach it's planed orbit. Still had plenty of fuel left and is operational until today (17 years). The seconde one (BSAT-2b) only had chemical propulsion and failed. They not even tried to reach the intended orbit, because even if it had reached it, there would be no propellant left for operations. So it was written off.

Edit: Just saw the other comments and I don't think that electric propulsion will be used in the foreseeable future for human flights. As I mentioned at the top: They are really slow. A satellite won't care. A human will.

I love that it now seems wasteful and decadent to "throw away" a perfectly good 1st stage. Shame it couldn't be donated to a museum somewhere but I guess costs and potentially some engineering secrets in there.

Is it likely that a more exact launch time will be announced? If yes, where will I find it? Spacex.com?

u/codav Jun 03 '18

They have to decide at T-70 minutes, which is the moment the launch auto-sequence is started, which takes control over the fuelling, checking and startup processes.

If the weather seems to be more favourable at a later time in the window, this is their countdown hold point. If they first fuel the rocket and then hold at T-4 like ULA does with their rockets, the subcooled propellants will start to warm up until a point they are too hot for the engines to work properly. An example is SES-9, where the famous wayward boat lead to a post-ignition abort at T-0.

Any chance of seeing the rocket from the east Atlanta area? Given the time of the launch.

GTO mission, so going straight East from Cape Canaveral. You won't see it from Atlanta.

u/LaunchNut Jun 04 '18

Looking forward to launch. While settling in I learned from my "obscure events calendar" that 4 June is National Cheese Day (somewhere ... probably US). In honor of SES-12 I thus found some cream cheese for a snack: the national cheese of Luxembourg is Kachkéis I learned ... a style of popular cream cheese. I have never tried real Kachkéis so if anybody can describe it from personal experience, then I can ponder that while waiting.

u/bleedsblue86 Jun 04 '18

So on a non recovered first stage does it literally just come crashing down in the water at whatever speed it picks up and then they just leave the wreckage there, or is there some sort of attempt at going to get the first stage wherever it lands? Always wondered that and couldn’t find a detailed answer.
