SES-9 Technical Webcast

SpaceX’s Falcon 9 rocket will deliver SES-9, a commercial communications satellite for SES, to a Geostationary Transfer Orbit (GTO). SES is a world-leading satellite operator that provides satellite-enabled communications services to broadcasters, Internet service providers, mobile and fixed network operators, and business and governmental organizations worldwide using its fleet of more than 50 geostationary satellites. SpaceX is targeting an evening launch of SES-9 from Space Launch Complex 40 at Cape Canaveral Air Force Station, Fla. The approximately 90-minute launch window opens on March 4 at 11:35 pm UTC. The satellite will be deployed approximately 31 minutes after liftoff.

I'm glad spaceX also postes a technical webcast. Can't really stand all the screaming and stupid comments...

"We used to look up at the sky and wonder at our place in the stars. Now we just look down, and worry about our place in the dirt.

We must reach far beyond our own lifespans. We must think not as individuals but as a species.

We're not meant to save the world. We're meant to leave it. This world's a treasure, but it's been telling us to leave for a while now." ーinterstellar, 2014

What a great display of high performance rocketry. Well done Spacex!!

[gojeda]

I am speculating here, but based on the feed off the recovery barge - I get the feeling they didn't stick the stage 1 landing. It didn't look anywhere near the center of landing platform to me.

[JanitorIsBack]

much better than listening you those other people

[MazonDel]

Congrats SpaceX on another successful launch!

[connorharkness]

woo, after many attempts, finally a successful launch of the mission. good job +spaceX and I look forward to seeing more launches from you guys

[BigHappysPlace]

as it is nice listening to them. they tend to repeat WAY to much or just ramble on. i am glad they did it this way. much better.

Шокирующе подробно и ужасающе интересно. Нам в СССР никогда так подробно не показывали. Я сидел с калькулятором и непрерывно вычислял скорость полета в км/сек и сравнивал с высотой. Многое в моих представлениях о взлете ракеты поменялось. Оказывается во многом происходит совсем не так, как я думал

What's going on with the fire licking out sideways between the first stage nozzles from about 10:45 ? Is that just unburnt exhaust recirculating around the nozzles as the airflow patterns change, or was there some kind of fuel leak?

[mikigm]

Could you publish a video of Dragon processing, mating with Falcon and rollout? Not a short one, but a bit more detailed one. I've never seen that part, and I bet it is as interesting as the launch itself. :-) Thanks

Satellite in orbit, pays the bills. Great deployment again SpaceX. Try, try again on 1st stage!

[GregoryGHarding]

anyone else have issues loading this stream? the full webcast worked fine but technical refused to play for me

[nerx]

Waiting for any news about landing of 1 stage.

[deancavander]

I assumed the barge landing of the 1st stage was not successful. I think the rocket tumbled down and disabled the video camera aboard the drone ship hence the colored bars when I was watching. We'll see on incoming broadcasts of the landing. I hope it was successful but if it was a success, they should have shown it during the live launching.

[tojhto]

where the sound from while 2nd stage's engine is showing. do they have also mic onboard?

[CmdrGendoIkari]

*Elon* this is my question; Does the barge platform communicate its motions in real time to the 1st stage guidance computer?

I'm starting to think that if you guys haven't tried to do something along those lines, that is probably the thing to do. The 1st stage needs to be able to anticipate the rocking motions of the platform just before touch down, or else landing on it may always be hit and miss. I think if the platform could just tell the rocket exactly what is happening with its motions, then the rocket could calculate the exact frequency and amplitude of the ocean waves at that moment in order to adjust it's landing trajectory. Maybe this is already a part of the system, but couldn't find anything specific about it last time you guys tried this barge landing routine.

[Merilix]

Well done!

What will happen to the 2nd stage now?
Another piece of space junk or will it burn in the atmosphere?

[KingOfSuccess-vj]

The first stage landing was not successful! 😕

[vicplichota]

An accelerometer readout would be way cool...
