Arianespace will use an Ariane 5 ECA rocket, designated VA228, to launch the Intelsat 29e communications satellite. Intelsat 29e is the first Intelsat Epic high throughput satellite, hosting a next-generation all-digital payload that can be reconfigured in orbit and is resilient to interference and jamming. Intelsat 29e offers coverage spanning North and South America, the Gulf of Mexico, the Caribbean Sea, and the North Atlantic aeronautical route connecting North America and Europe.
The launch will begin in 4 hours.

>nice powerful rocket
>beautiful tropical scenery
>showing the world how GTO is fucking done
But I agree Vega launches are more "exciting" since it's a very recent and modern rocket.
>blowing up every time they try their shitty landings
>every time it's a different excuse
They're just amateurish. Why do you think Ariane beats them? Besides that ground landing was only possible because they were sending a very light payload (2000kg) into an earth-grazing orbit. Not exactly impressive when Ariane sends 5 times that mass into fucking GTO.
This. Rosetta was 3000kg and we sent it to Jupiter and back around a fucking comet.
F9 is a nice rocket though, but people over-inflate their performance because muh Elon.
why do you think its way harder to do a bigget payload? its just a bigger tube with more gas its the same concept doing the same thing meanwhile spacex is actually trying new things that will push the industry forward
The funny thing is that the reason Intelsat picked Arianne for this EpicNG launch (and certainly the next ones) is because there is no other rocket capable of lifting these sats. The only other option would be a Detla 4 heavy, which costs ... twice the price.
And they are not naive enough to wait for the spacex rocket that's perpetually 6 months away from maiden launch.
Fireworks technology is for entertainment.
Real space travel uses field propulsion.
Totally boring, the craft just disappears.
Erm, not really. It's not just about having more fuel. Ariane 5 really is a more advanced rocket.
>3 stages vs. 2 for F9
>Vulcain II engine has an ISP of 434.2s vs. 311s for the Merlin (SpaceX fans like to say the Merlin as "the highest thrust-to-weight ratio ever" but has never been a figure of merit of rocket engines for two basic reasons: 1. the quasi-totality of a rocket's mass lies in the fuel and 2. just look at srb's for thrust-to-weight ratio above several thousands since it's just a nozzle basically. ISP has always been the actual figure of merit of a engine, along with it thrust of course)
>novel vibration reduction techniques for the srb's that even got JPL interested
You know you can't directly compare the Vulcain and Merlin ISP because they use completely different propellants right? Vulcain uses hydrolox so it's always going to have better ISP.
Comparing the isps of the two engines on their own isn't really a good comparison. The Vulcain II's superior isp isn't because it's a more advanced engine. It's because ESA went with a LOX/LH fuel mix for Araine-5 and a LOX/LH engine will almost always have a better isp than a LOX/Kerosene engine.
Yes. You can't put LH2 in a merlin or KErosene in a Vulcain II. That was my point. That's exactly why you shouldn't compare them based solely on isp. A LOX/LH2 fuel mixture will always provide a better isp than LOX/RP-1. The Vulcain II's isp advantage is due to the fuel mixture not being "more advanced".
private space flight is so boring
>mfw nations will never be united behind the common goal of space exploration anymore and nobody watches rocket launches anymore
They went with Kerosene because they felt that the loss in isp could be made up elsewhere. LH2 provides superior isp but at the cost of heavier tanks and plumbing due to LH2 being cyrogenic.
