Ariane 6 exists so that European countries can get independent access to space between now and 2030s. The launch cost is almost 2x the cost of Falcon 9. Both platforms can lift 22t to LEO. 6-10 years from now Ariane Next/SALTO will aims replicate Falcon 9 efficiency and the design will be very similar: reusable, RP-1/LOX, Prometheus engine is similar reusable open cycle engine as Merlin with lots of 3D printed parts.

> “The launch cost is almost 2x the cost of Falcon 9.” This actually seems quite reasonable considering the Ariane 6 is a non-reusable, low-volume design.

It’s after subsidies [1]. Actual costs are 4 to 6x Falcon 9, and that’s comparing actual costs today for Falcon 9 to projected costs in the future for Ariane 6.

Earlier quoted context omitted.

Ariane is one generation behind SpaceX, but that still puts them on second place. All while being independent from the whims of one single individual, ensuring independent launch capabilities for national security reasons.

> Ariane is one generation behind SpaceX, but that still puts them on second place. The first doesn't imply the second. Ariane 6 is behind: * ULA's Vulcan * SpaceX's F9/FH * SpaceX's Starship (who knows when it'll start launching payloads) * Blue Origin's New Glenn (supposed to be launched in September) in terms of raw performance as well as $/kg. There are also a number of other rockets like RocketLab's Neutron and…

And that’s before we start counting in China and, soon, possibly, India.

Ariana 6 might be the stupidest civil aerospace project in the world after Boeing’s Starliner.

Arguably at most third place, since partly reusable New Glenn (Blue Origin) is already planned to launch in a few months, currently September. Though lower stage reuse might only happen later.

Even though this is not impressive compared to SpaceX, it is still essential that we have multiple actors building rockets. The competition makes sure that SpaceX needs to push the boundaries. Our future as a multi-planetary species is not dependent on a single actor. I'm hoping for some space race. It would be great if the United States would transfer a part of MIC funding to space exploration.

I don't think it is that impressive anymore. We've been building rockets for decades. Making them return to Earth is peanuts compared to building a self driving car. You can even make a simulation that is 99% accurate without much effort. Also, rocket science is just Newtonian physics. Of course, building a rocket requires a shit-ton of resources, so if anything is impressive then it's the management of those resourc…

Spoken like a true software engineer ;)

China is... weird.

Most of the rockets they launch are small hypergolic rockets (Long March 2-4) with clear ICBM heritage. Which are multiple generations "behind" Ariane 6.

They do have some more modern cryogenic rockets, but they can't seem to scale those operationally. Presumably it'll happen eventually. But who knows when that'll be.

> 6-10 years from now Ariane Next/SALTO will aims replicate Falcon 9 efficiency and the design will be very similar: And by then, SpaceX will be 10 years ahead of them with a next-gen platform. Not a great sounding story.

For any European? Thats fantastic. Let that ego maniac and putin's admirer chase latest and shiniest, we all will learn from his success and failures.

We (US vs Europe) are not racing nor competing in this in any way, we just need to put out payload up there too. We desperately need our own skillset though, with Trump or similar breed potentially at power across the pond US will become more hostile towards Europe and let russia roll over Ukraine and maybe further, absolutely no doubt there.

Are the Europeans wworried that "between now and 2030s" the US will cut off their access to space? I understand things can go wrong and it's good to have a backup plan in the long term... But that's not that many years out. You can go without access for a few years .. It seems like a tiny risk

Not really, but European countries launch military payloads and other strategic stuff like Galileo satellites and communication satellites.

All are friends with NATO, but that does not exclude spying and all kinds of shenanigans. US spies non-Five Eye countries mercilessly. They get caught sometimes. Like the systematic wiretapping trough Danish cables from 2012-2014.

> it is still essential that we have multiple actors building rockets. The competition Twice the cost and at a small fraction of the frequency is competition in the way a rubber duck competes with a battle ship. Ariana 6 isn’t meaningful competition. ArianeSpace’s sole value is in its potential of becoming competition if one day sensibly managed.

Yeah this is ESA's see-we-have-domestic-launch-capability pointless SLS tier project basically, my tax dollars at work.

I'm really puzzled at the lack of investment into any kind of reusable launch vehicle that could even come close to competing with SpaceX. Launching on this expensive relic of the past makes zero sense unless your payload is a military spysat.

> So because an incumbent exists ESA should give up No. But they should learn their lesson and try to run instead of plodding along at a glacial pace. Oh but wait, they're govt funded with no success incentives other than some sort of vague sense of pride for a job well done. My money is on they're not going to come out ahead in the race.

I would rather work for the government than working to make someone so rich even more rich. To each their own.

That is fine. Government should still be reasonably efficient. Not as efficient as possible by any means possible, with the ethical problems megacorporations have. But reasonably efficient.

So it's worth keeping an eye on things and making comparisons. I at least, don't say any dollar more than SpaceX spent by Ariane is bad. But if they spend multiple billions more... maybe we could build some trains or something for that money.
