Some older news. Copied accros from the Ariane 5 ME Updates thread:

http://www.astrium.eads.net/en/press_centre/astrium-wins-contracts-to-design-ariane-6-and-continue-development-of-ariane-5.html

Quote
The European Space Agency (ESA) has awarded Astrium, Europe’s leading space technology company, €108 million worth of prime contractor agreements covering the development of the Ariane 6 and Ariane 5 ME launchers. The contracts follow on from the decisions reached at the ESA Ministerial Council meeting in Naples on 20-21 November 2012.

Slightly less older development news.

http://www.cnes.fr/web/CNES-en/10705-gp-europe-sets-its-sights-on-ariane-6.php

Quote
Ariane 5 is hamstrung by the need to find 2 satellites ready to launch every 2 to 3 months and compatible with its lift performance,” notes Joseph Berenbach. “On the other hand, Ariane 6 will launch a single satellite at a time, so it will be much more flexible and responsive: customers will no longer have to wait to launch their spacecraft.

Some more older news, from a French source, but it contains the first views of the proposed launch zone for Ariane 6:

http://www.usinenouvelle.com/article/ariane-6-implique-la-construction-d-un-nouveau-pas-de-tir-a-kourou.N188375

Translation mine:
Quote
On Wednesday, December 19, 2012, in the combined ESA/CNES facility, in the 12th arrondissement of Paris, Michel Eymard, CNES Director of Launchers presented a model of the future Ariane 6. (Note: see image below)Performed in 3D-printing, it represents the"PPH" configuration of the rocket, with three solid boosters on the lower stage (first stage), a similar solid booster above the lower stage, and a cryogenic upper stage.

The favorite configuration of CNES for the future Ariane was already known before the Ministerial Conference in Naples. However, the future launch area of the launcher was never previously revealed. Christian Canart, CNES project manager for the Guyana ground facilities, presented the future site plan and an artist impression.

"It's included in the $ 4 billion?" the concerned ESA minister Geneviève Fioraso immediately asked. The answer from CNES President Yannick d'Escatha was immediate: 'Yes, it's included'.

Like Vega, the small European launcher, Ariane 6 final assembly is performed directly on the pad. In contrast, Ariane 5 was assembled in a building, then received it's payload and fairing in another building, before being transferred to the launchpad.

The map below shows the area of the Guiana Space Centre, which would be dedicated to Ariane 6. In the BICI (Lower Composite Integration Facility), the solid boosters for the lower two stages are integrated, before being stored in the BSE. ZL means launch area. The cryogenic upper stage and payload-composite are assembled directly on the pad. Two launch areas (ZL1 and ZL2) may be considered for parallel launch processing.

Everything will be located north of the Ariane 5 launch area.

Production units for the solid booster propellants are extensions of existing units which are also located inside the Guiana Space Center.

So, they'll have a mobile integration tower, that will also enclose a fixed service tower (for H2, auxiliary gases, etc.). They did stated that they would integrate the lower three solids on a separate building. So I'm assuming it will have some sort of mobile bed? Or will the service tower and bed be integrated like the Atlas V's MLP?
BTW, I still don't see how will they scale down performance. Unless they can do a PPH with a single solid at the base.

Normally, when little "wings" are added, is usually to keep aerodynamic stability at separation. For a famous example, the Saturn V needed them to keep the first stage from deviating enough to guarantee the safe escape of the Apollo in case of an abort. Without those wing, if the avionics section failed, the rocket could tumble more than the time needed to eject the capsule in a safe attitude. I.e. before the rocket would break down by aerodynamic forces. Thus, I would speculate that those are there to keep the expended rockets from contacting their neighbors during separation.

The recent ESA update on Ariane 6 also includes a short term timeline of what is to happen in this year:

http://www.esa.int/Our_Activities/Launchers/Launch_vehicles/Ariane_6

Quote
Ariane 6 elements

The Ariane 6 is a three-stages configuration (called PPH) powered by solid propulsion for the lower composite (first two stages) and with a cryogenic liquid oxygen and hydrogen for the upper stage.

For the lower composite, several options are being considered in terms of number, loading and arrangement of motors.

For the upper stage, Ariane 6, similarly to Ariane 5 ME Adapted, will use cryogenic propulsion for the upper stage based on the Vinci engine. It will be restartable and have direct deorbiting features.

Ariane 6 work logic

The preparatory work has begun, with a first phase of trade-offs between different PPH concepts that will lead to the selection of one Ariane 6 concept by the second quarter of 2013. Analysis will begin on the selected concept during the feasibility stage, planned for completion in mid-2013.

Some of the Ariane 6 concepts under investigation

This will be followed by the preliminary definition phase which aims to show the overarching objective of the Ariane 6 launch system can be met: reduced exploitation costs.

The complete development of the Ariane 6 launch system will be proposed at the 2014 Council at ministerial level.

Little late update:

http://www.spacenews.com/article/launch-report/35469with-ariane-6-launch-site-selected-cnes-aims-to-freeze-design-of-the-new#.UaL3EpFrOHN

Quote
PARIS — The French space agency, CNES, expects to freeze the final design of the new-generation Ariane 6 launcher by July, a milestone that will trigger work on a new launch pad in French Guiana whose location has already been decided, according to CNES officials.

The rocket and the launch installation are being designed to operate Ariane 6 at least eight times per year, with a mission goal of 12 flights annually to keep production and operations costs within the targeted 70 million euros ($91 million) per launch.

At somewhere between eight and 12 flights per year, including three or four European government missions, Ariane 6 would no longer need the annual price supports that the current heavy-lift Ariane 5 still requires despite a decade-long run without a failure.

The 20-nation European Space Agency (ESA) pays about 100 million euros per year to the Arianespace commercial launch consortium to permit the Evry, France-based company to avoid financial losses.

The 70 million euro target for Ariane 6 is viewed as an all-in cost that would include about 14 million euros per launch in ground operations and also would include the sales and marketing charges incurred by Arianespace.

Taking advantage of work done years ago on what was then a quarry, CNES officials have selected a site to the north of the Ariane 5’s launch site for Ariane 6, an area called Roche Nicole. Quarry construction left a large pit, now filled with water, that will be used for the Ariane 6 flame trench.

CNES officials say that because of the quarry work, done to support launches of the now-retired Ariane 4 rocket, the flame trench is now the equivalent of 70 percent complete even though no work has begun on it.

Europe Urged To Halt Work on ‘Dead End' Ariane 6 Design

Europe’s Air & Space Academy says the French and European space agencies are moving in the wrong direction on the future Ariane 6 rocket and should delay development in favor of a redesign that provides more growth potential.

The academy is urging the agencies to stop work on the Ariane 6 they approved in November with a view to beginning full development in 2014. The academy-favored rocket would use liquid propulsion instead of solid, and would face four more years of preparatory work before moving to full development in 2018.

In the meantime, the academy says, Europe should focus on an upgraded heavy-lift Ariane 5 that would fly for a decade before both it and the Europeanized version of Russia’s medium-lift Soyuz rocket are replaced by the all-liquid Ariane 6 in 2027. This rocket, called Ariane 5 ME, has been in design for several years. Continued work on it was approved, alongside Ariane 6, at the November meeting of European Space Agency (ESA) governments.

Discussing this news article should be done in the Ariane 6 DISCUSSION thread. Thank you.

Here is the ESA response to the recent call for a pause in Ariane 6 development:

http://www.spacenews.com/article/launch-report/35678ignoring-call-for-strategic-pause-esa-intends-to-stay-the-course-on

Quote
Ignoring Call for Strategic Pause, ESA Intends To Stay the Course on Ariane 6

The European Space Agency (ESA) has no intention of changing course for its future Ariane 6 rocket despite pointed criticism of the selected design by former ESA and European industry launch-vehicle experts, ESA Launch Vehicle Director Antonio Fabrizi said June 7.

Fabrizi said the current design, using two solid-fueled stages topped by a cryogenic upper stage, received the specific endorsement of ESA’s governments last November and cannot simply be set aside. He said the vehicle’s final design — both a single-block first stage and a multiblock cluster are being discussed — will be settled by early July.

SPACEFLIGHT Magazine VOLUME 183 NUMBER 5396, 25 JUNE-1 JULY 2013
Critical Ariane design decision looms
Quote
ESA committee considers configuration options for successful launcher’s sixth incarnation, set to be revealed at end of June
The shape of Europe’s next launcher will be revealed as soon as end-June, with the selection of the configuration of the Ariane 6 rocket.
The European Space Agency’s industrial policy committee is choosing between a variety of solid-fuel stage arrangements, in a bid to replace the Ariane 5 heavy lifter with a less-expensive and more flexible – but equally reliable – alternative for flight from the early 2020s.
Speaking at the Paris air show, ESA director general Jean-Jacques Dordain said the move to solid fuel – rather than the liquid hydrogen and oxygen liquid motors that power Ariane 5 – represents a 10-year technology selection process.
Ariane 6, approved for development by ESA member state space and industry ministers in a five-year budget deal set in November 2012, is a bid to maintain Europe’s leading position in 
launches of big telecommunications satellites and other heavy payloads with a modular rocket system that allows components to be built in advance, stored and assembled as needed. Today,
each Ariane 5 must be tailormade for a specific payload.
Separately, Alain Charmeau, chief executive of Ariane 5 and 6 prime contractor Astrium Space Transportation, says his key challenge is to reorganise the European space industry to develop
and deliver Ariane 6 to a target launch price of about €75 million ($100 million) – that is, to be organised to work backwards from a market-competitive price rather than set a launch price
based largely on the cost of manufacturing and development.
NASA, said Charmeau, is the inspiration for this bold bid to reconfigure the European industry.
By setting objectives rather than specifications, NASA is starting to benefit from private sector innovation. SpaceX and its Falcon 9 rocket is the most visible example.                                     
Cutting costs, adds Charmeau, is going to mean delivering vehicles with fewer people working in the supply chain. “This is the challenge,” he says.
Meanwhile, Ariane 5 is being upgraded to add about a fifth to its payload capacity – to 12t. ESA’s industrial policy committee will next week sign contracts to see that work through to 2017, when the so-called Midlife Extension variant is due to fly, says Dordain.
He hopes ESA member states – particularly France and Switzerland, who lead development of Ariane 5 and its payload fairing – will approve “a fairly small amount of money”, about €30 million, to engineer a slightly enlarged fairing volume, to accommodate electric propulsion units for satellites inside. These represent a significant advance in satellite control, and reduce the mass of fuel that must be launched to orbit.

Not a new version but an older version. This is one of the notional versions that were presented shortly before the november 2012 ESA ministerial conference.

Ok, but what size are the boosters? To my knowledge it has always been 3xP135 - 1xP135 - US. Or the version with strap-ons.

This however must be something different, maybe P100 which is planned for Vega evolution?

CNES had apparently done away with the 'clustered' set of 3 P135's in the first stage. The P135's are now more conventionally positioned 'in a row'.

Are the three boosters in the first stage "row" linked together, or does the middle one have a different fuel layout to burn longer?

First stage has 3 Solids. Second stage 1 Solid. Third stage lox. (I hope they manage to keep all solids as equal as possible).

Are the three boosters in the first stage "row" linked together, or does the middle one have a different fuel layout to burn longer?
First stage has 3 Solids. Second stage 1 Solid. Third stage lox. (I hope they manage to keep all solids as equal as possible).
All three first stage motors burn out at the same time and are foreseen to be separated in one piece.

Astrium awarded three new contracts by ESA for Ariane 6 and Ariane 5 ME launchers

http://www.astrium.eads.net/en/press_centre/astrium-awarded-three-new-contracts-by-esa-for-ariane-6-and-ariane-5-me.html

Quote
- €106 million contract for continued development of the Ariane 5 ME

- €278 million contract for continued development of elements common to the Ariane 5 ME and Ariane 6 launchers

- €30 million contract to kick off preliminary studies for Ariane 6 in 2013

Quote
The third contract is for the start of development studies for the Ariane 6 launcher, based on the concept selected in July.
Quote
Astrium will now press ahead with definition and feasibility studies on the future Ariane 6 European launcher. These studies aim to define the chosen concept and architecture of the Ariane 6 launcher and to specify its main characteristics prior to the start of its industrial development, in 2014.
Quote
The Ariane 6 and Ariane 5 ME launchers will both feature the same liquid-propulsion system in their upper stages, specifically the Vinci® engine, and largely the same fairing.

http://www.esa.int/Our_Activities/Launchers/Ariane_6_moves_to_next_stage_of_development

Quote
In early July (2013), seven months after ESA’s Ministerial Council decision (2012), the concept for the Ariane 6 vehicle was selected.

On 1 October the Preliminary Requirements Review of the launch system began. The management plans and the preliminary specifications together with the technical and programmatic files of the concept were submitted for review.

The review was concluded by the board on 6 November. The review involved European experts from Arianespace, Italy’s ASI space agency, France’s CNES space agency, the DLR German Aerospace Center and ESA. European customers also participated and contributed to the consolidation of the Mission Requirement Document, which will drive the development.

The next step for the Ariane 6 project is the completion of a first Design Analysis Cycle, which is planned for the end of February, and which includes trade-offs for several subsystems. A second Design Analysis Cycle will start in March. The results of the second loop will feed the next ESA review: the System Requirements Review, planned for October–November 2014.

New pic.

Other info from the CNEStweetup. A6 could evolve into a 4t or 8t launcher, depending on the market. The 8t version would be doable with 5 solid motors in the first stage.

Germany’s Budget Straitjacket Complicates Europe's Ariane Funding Outlook

http://www.spacenews.com/article/launch-report/40655germany%E2%80%99s-budget-straitjacket-complicates-europes-ariane-funding-outlook

Quote
Germany has informed the European Space Agency that German spending on launch vehicles will remain flat for the next decade, a decision that complicates the agency’s already difficult attempt to secure funding and design consensus for a new-generation Ariane rocket. Because of Germany’s weight in any realistic rocket-funding scenario in Europe, the German decision means the 20-nation ESA will be limited to an annual launcher budget of around 850 million euros ($1.2 billion) per year between 2015 and 2024.

I think we should also link this: http://www.safran-group.com/site-safran-en/press-media/media-section/article/safran-airbus-group-launcher?14008

Quote
What do Airbus Group and Safran recommend for Europe’s future Ariane 6 launcher?

We’re ready to propose to the European Space Agency (ESA) two versions of this launcher, called Ariane 6.1 and 6.2. Each of these versions will comprise a solid-propellant first stage, with two P145 boosters, and a new central stage derived from the current stage and using the Vulcain 2 cryogenic engine developed by Snecma, at optimized cost. The difference between the two versions is in the upper stage: Ariane 6.1 will be based on the Vinci engine (also developed by Snecma), as on the Ariane 5 ME (Midlife Evolution), while the Ariane 6.2 upper stage would be powered by an Aestus engine (developed by Airbus Defence and Space, formerly Astrium), as on the Ariane 5ES*.

Ariane 6.1 would be able to boost up to 8.5 metric tons into geostationary transfer orbit (GTO), making it possible to launch two satellites that weigh up to four metric tons and use electric propulsion – reflecting a major market trend over the past two years. Ariane 6.2 would be intended mainly for smaller satellites, especially those launched by governments.
We believe that this configuration would reduce the development efforts needed for Ariane 6, while still meeting the cost and performance objectives stipulated by ESA. Furthermore, it would provide the modularity requested by customers, and would also offer synergies with the entire family of European launchers, including Vega.

One industry official conceded that the new version’s commercial variant, to carry up to 8,500 kilograms into geostationary transfer orbit for telecommunications satellites, would cost around 100 million euros per launch instead of the 70 million euros that ESA and CNES had sought in their design.

Ariane 6 (Updated article)

Quote
Ariane 6 objectives and main missions

The overarching aim of Ariane 6 is to provide guaranteed access to space for Europe at a competitive price without requiring public sector support for exploitation.

Different concepts have been examined for Ariane 6 such as single- and dual-payloads, solid or cryogenic propulsion for the main stage, and the number of stages (three or more), all to cover a wide range of missions:

- GEO, either directly or through intermediate orbits, in particular GTO and LEO,
- Polar/SSO,
- MEO or MTO,
- other.

The targeted payload performance of Ariane 6 is 4.5 t for polar/Sun-synchronous orbit missions at 800 km altitude and 3–10 t, with two main segments (3.5-5 t and 6–6.5 t) in GTO-equivalent.

The exploitation cost of the Ariane 6 launch system is its key driver. The first flight is targeted for 2020.
 
Ariane 6 concepts

Configurations that maximise commonalities between the rockets’ stages, and flexibility for adapting to an evolving commercial market, are considered more likely to lead to a competitive launch service price.

Ariane 6 is a modular three-stage launcher (solid–cryogenic–cryogenic) with two configurations using: four boosters (A64) or two boosters (A62).

This is based on:

- A main stage containing liquid oxygen and hydrogen based on the Vulcain engine of Ariane 5 ECA and ME;
- Two or four P120 solid rocket boosters, which will be common with Vega-C (an evolution of the current Vega launcher);
- A cryogenic upper stage (LOX/LH2) propelled by a Vinci engine, based on the A5ME upper stage, with limited adaptations.

Ariane 6 in its A62 or A64 configuration is deemed the best possible long-term solution to maintain competences in Europe and deliver launch services against competitive costs.

Ariane 6 will have reignition capability and will be capable of performing a direct deorbiting and controlled reentry of the upper stage.

Flexibility is a design characteristic for A64 and A62. In essence it is the same launcher, responding to different market needs by varying the number of boosters in the configuration.

The A62, with two P120 solid boosters, will be used mainly in single-launch configurations, while the A64 – with four P120 solids – will enable double launch of medium-class satellites up to 4.5–5 t, mainly for commercial market needs.

The main characteristics of the Ariane 6 concept are:

- The total length of the vehicle is around 63 m,
- The loading of the cryogenic main stage is about 149 tonnes of propellants,
- The external diameter of the cryogenic main stage is about 4.6 m.

http://www.spacenews.com/article/launch-report/42472to-win-over-germany-esa-maps-out-how-ariane-6-would-save-everyone-money

Quote from: Peter B. de Selding
The European Space Agency is proposing to inject 8 billion euros ($10 billion) into Europe’s launch sector over 10 years starting in 2015, including some 4.3 billion euros on a new Ariane 6 rocket, on the basis of a contract arrangement with industry in which ESA guarantees five government missions per year and, in return, industry fends for itself on the wider commercial market.

I'll write an article, but:

N° 30–2015: ARIANE 6 AND VEGA C BEGIN DEVELOPMENT

12 August 2015

Today, ESA signed contracts for the development of the Ariane 6 new‑generation launcher, its launch base and the Vega C evolution of the current ESA small launcher.

The contracts, signed at ESA’s Paris Head Office with Airbus Safran Launchers (ASL), France’s CNES space agency and ELV, respectively, cover all development work on Ariane 6 and its launch base for a maiden flight in 2020, and on Vega C for its 2018 debut.

“These contracts will allow the development of a family of European launchers, highly competitive in the world market and ensuring autonomous access to space at fully competitive prices for ESA’s Member States,” said Jan Woerner, Director General of ESA.

“They are an important change of governance in the European launcher sector, with industry being the design authority and taking full responsibility in the development and exploitation of the launchers, and committing to deliver them to ESA and the European institutional actors at specified competitive prices.”

ESA is overseeing procurement and the architecture of the overall launch systems, while industry is developing the rockets, with ASL as prime contractor and design authority for Ariane 6, and ELV for Vega C.

ASL and ELV are working closely together on the P120C solid-propellant motor that will form Vega C’s first stage and Ariane’s strap-on boosters.

Ariane’s modular approach will offer either two boosters (Ariane 62) or four boosters (Ariane 64), depending on the required performance.

The site of the launch pad for Ariane 6 at Europe’s Spaceport in Kourou, French Guiana has been chosen, and prime contractor CNES is already excavating the site. The new complex will also include facilities for preparing the launcher.

The three contracts follow the decision taken at the ESA Council meeting at Ministerial level held in Luxemburg in December 2014 to maintain Europe’s leadership in the fast-changing commercial launch service market while responding to the needs of European institutional missions.

 “With the signing of these contracts we are on track on building a new family of launchers featuring common building blocks, in line with the decisions and schedule set at the Ministerial Meeting in 2014,” said Gaele Winters, ESA’s Director of Launchers

The contracts were signed by Gaele Winters, ESA’s Director of Launchers; Jean-Yves Le Gall, President of CNES; Alain Charmeau, CEO/President of ASL; and Pierluigi Pirrelli, CEO of ELV.

The contract amounts are: €2400 million for Ariane 6 (ASL), €600 million for the launch base (CNES) and €395 million for Vega C (ELV).

About the European Space Agency

The European Space Agency (ESA) provides Europe’s gateway to space.

ESA is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe's space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.

ESA has 20 Member States: Austria, Belgium, the Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom, of whom 18 are Member States of the EU. Two other Member States of the EU, Hungary and Estonia, have signed Accession Agreements to the ESA Convention and will soon become new ESA Member States.

ESA has established formal cooperation with seven Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement.

ESA is also working with the EU on implementing the Galileo and Copernicus programmes.

By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country.

ESA develops the launchers, spacecraft and ground facilities needed to keep Europe at the forefront of global space activities.

Today, it develops and launches satellites for Earth observation, navigation, telecommunications and astronomy, sends probes to the far reaches of the Solar System and cooperates in the human exploration of space.

Picture of Vega C and Ariane 6 under the same link.

Looks like Vega C will get a new 2nd stage in addition to a new 1st stage. Plus a huge fairing.

Ariane 6's boosters look fatter than in earlier renderings. Probably larger diameter and shorter.

Concur: good story.
Another minor nit: the first image of the article is of the older, all-solid, version of Ariane 6. This PPH configuration is now no longer applicable, so it might be a good idea to replace that image.

Artist's view of the two configurations of Ariane 6

Artist's view of the two configurations of Ariane 6 using two boosters (A62) or four boosters (A64).

ESA and European industry are currently developing a new-generation launcher: Ariane 6. This follows the decision taken at the ESA Council meeting at Ministerial level in December 2014, to maintain Europe’s leadership in the fast-changing commercial launch service market while responding to the needs of European institutional missions.

This move is associated with a change in the governance of the European launcher sector, based on a sharing of responsibility, cost and risk by ESA and industry.

The participating states are: Austria, Belgium, France, Germany, Ireland, Italy, Netherlands, Norway, Romania, Spain, Sweden and Switzerland.

PBDeS: "Airbus Safran Launchers Ariane 6 chief Patrick Bonguet: Ariane 6 will lift 2X the mass & 2X the volume of SpaceX Falcon 9 at < 2X the price."

https://twitter.com/pbdes/status/717705991714902016

Also: http://spacenews.com/ariane-6-rocket-designers-say-theyll-match-or-beat-todays-spacex-prices-on-per-kilogram-basis/

Seems like a tall order, or how do they get these numbers? Payload to GTO for Ariane 6 is 5 or 11 tons (62 and 64, respectively). I get double the mass (11 vs 6) and volume, but <2 the price? Even if it's on a per kg basis, 90 M$/11 tons is 8000 $/kg, whereas 60 M$/6 tons is 10000 $/kg.

(Edit: sorry if that is not news enough for the update thread, feel free to move)

Patrick said twice payload for less than twice price (per launch) which is cheaper per kg which your calculations confirm for F9 V1.1.

The F9 FT is likely to match or better the $8000/kg. More importantly it can do it on single payload with wider payload mass range as F9R can fly lighter satellites for same $/kg.

10.5 tonnes is ~twice Falcons 9's 5.3 (don't know where you are getting 6 from).  The 10.5 tonne Ariane 6 is supposed to cost ~€90m or on current prices just over $100m, which is less than twice the current ~$60m of Falcon 9.  So the claim is perfectly correct, the question is the delivery.

Keep in mind that the advertised Falcon 9 GTO payload is not a direct comparison to the Ariane 6 GTO payload, since Ariane 6 specifies GEO -1,500 m/s ish versus Falcon 9's GEO - 1,800 m/s ish.  Subtract a tonne or so from Falcon 9 payload to directly compare.  There's even a chance that Airbus Safran is talking about the advertised Falcon Heavy GTO payload, which is 6.4 tonnes.

The dream is moving to reality. That was the message from European Space Agency boss, Jan Woerner, on Wednesday as he discussed the Ariane 6 rocket.

The director general was touring the Airbus Safran Launchers facilities at Les Mureaux, France, where much of the future vehicle will be integrated.

Reporters were shown the progress being made towards a 2020 maiden flight.

SpaceX recently estimated pricing and if both estimates turn out to be correct:

FalconArian 62Falcon HeavyAriane 64
Prize| $62M| $86.2M| $90M| $103.5M
GTO| 8'300kg| 5'000kg| 22'200kg| 10'500kg

... what's the advantage of this new rocket, except when SpaceX is fully booked? As someone with no deeper understanding, it looks ridiculous.

Actually the Falcon Heavy price tag is related to a 8000kg GTO launch and the Falcon 9 one for a 5500 kg one.

GTO orbit are also slightly better from Kourou than from KSC.

But still, your question remains.

2 satellites will be launched on Ariane 64, so with this pricing Ariane 6 would be much cheaper than today's Falcon 9 spaceX with twice more performance. The big question mark is to anticipate prices from SpaceX in 2020. Ariane 62 Will only replace Euro Soyuz for institutional missions from ESA/EU at a similar price tag

Ariane 6 is taking shape

18 May 2016

The engine that will power the upper stage of Europe’s next-generation launcher completed its first test last week, demonstrating that Ariane 6 is forging ahead for a 2020 debut.

The DLR German Aerospace Center test facility in Lampoldshausen, Germany allows firings under near-realistic space conditions. The Vinci engine ran for 500 seconds, powered by super-cold liquid hydrogen and liquid oxygen and generating 18 tonnes of vacuum thrust.

Running until September, this test campaign is establishing Vinci’s characteristics and allowing engineers to build an accurate computer model.

As a restartable engine, Vinci will offer a wide range of payload combinations and pairing of different types of missions. Direct deorbiting or injection into graveyard orbits once its work is done will help to keep the space environment free of debris.

Just a few additonal info:
In the test mentioned above Vinci made a three-ignition test, i.e. it was re-ignited twice. The campaign in Lampoldshausen will also see the first tests with the new fixed nozzle for the Ariane 6 version of Vinci.

And this test was, of course, only the first one in the Ariane 6 program. Vinci has been tested already since 2005 at the ESA test stand P4.1 here in Lampoldshausen in the course of several programs (ESC-B upper stage, FLPP, Ariane 5ME upper stage).

Press release, 3 June 2016

New rocket test rig for safe Ariane 6 launches

The future European launcher Ariane 6 will debut in 2020. In order for it to bring all its payloads safely to their orbits, the engines for the new launcher must first be extensively tested. To test the upper stage of the new launcher, a new test rig
will be built at the German Aerospace Center (Deutsches Zentrum fuer Luft- und Raumfahrt; DLR) site in Lampoldshausen. The Chair of the DLR Executive Board, Pascale Ehrenfreund, and the Director General of the European Space Agency (ESA), Johann-Dietrich
Wörner, signed the contract for the development and construction of the P5.2 test rig for the Ariane launcher programme on 2 June at the International Aerospace Exhibition (ILA) in Berlin. All upper stages can be tested in this test rig – a capability
unique in Europe.

"The Ariane 6 is the future of European space transportation – and DLR is an indispensable partner. Before the first flight of Ariane 6, the upper stage of the new launcher will be put through its paces in Lampoldshausen. With this, DLR assumes responsibility
for the central task of making Ariane 6 as safe as its predecessors," said Ehrenfreund in Berlin. The upper stage of the Ariane 6 will be tested extensively on this new P5.2 test rig at the DLR site in Lampoldshausen. These include fuelling and defuelling
tests and hot running tests for the upper stage. The commissioning is scheduled to begin in 2018.

Commitment to Germany as an aerospace location 

The DLR Space Administration in Bonn lobbied for the new test bench to be built in Lampoldshausen. The German participation in the Ariane 6 programme will be controlled from this location. "Germany will have a 23 percent contribution in the new launcher,
making it the second largest partner after France. We want to participate effectively and contribute our expertise profitably within the European arena. The construction of this test facility in Germany is a clear sign and confirmation of the great
success of our commitment," explains Denis Regenbrecht, responsible for the Ariane 6 programme at the DLR Space Administration.

Extension of the test portfolio at the DLR Lampoldshausen site

The DLR Institute of Space Propulsion is technically responsible for the construction and subsequent operation of the test rig. At the Lampoldshausen site, DLR tests liquid rocket engines of different power classes on behalf of ESA and the European
space industry. "The P5.2 is a major expansion of our test portfolio," explains Stefan Schlechtriem, Head of the DLR Institute of Space Propulsion. "In addition to engines and their components, we will be able to use it to test complete upper stages
in future. This capability is unique in Europe."

Ariane 6 – Europe's future space transportation

The Ariane 6 development programme was approved at the ESA Council at Ministerial Level in December 2014 and signed by 12 member states. With its first launch set for 2020, this European launcher system currently in development is globally competitive
and will guarantee European access to space for ESA Member States. The total launch costs will be reduced by almost 50 percent compared to the Ariane 5. The major contractor for developing the Ariane 6 is the Franco-German company Airbus Safran Launchers
(ASL). Another significant German player in this development is the Augsburg-based company MT Aerospace.

Just as additional information to the press release above:
The bottom image shows the test stand P4.1 where the further above-mentioned Vinci campaign is currently ongoing.
Once the Vinci design is frozen the upper stage can be tested (together with Vinci) on the new test stand P5.2.

The new Airbus Safran launches website has a segment with details about Ariane 6.
A64 will have a takeoff weight of 860mT and can deliver at least 10,5mT to GTO {-12.
A62 will have a takeoff weight of 530mT; it can deliver 5mT to GTO and 7mT to SSO {?800km}
The Solid Rocket Motors are still named P120C.
The core stage is named Lower Liquid Propulsion Module, it will contain 150mT of LOx and LH2, it will be powered by the 1370kN Vulcan 2.1. It will have a burn time of 460 seconds.
The upper stage Upper Liquid Propulsion Module, will contain 30mT of LOx-LH2, powered by the 180kN Vince2 that is re-ignitable and will burn for 900 seconds.

(So the GLOW of both A64 and A62 have increased 30mT)

Nice find Oli that's the most detailed image of Ariane 64 I've seen so far.

Sorry for not paying attention and posting a massage that belongs in the discussion topic.
I've reposted the massage there. Please keep this a update only topic, continue discussions in the other topic.

Comparing the different liftoff masses and thrusts of both Ariane 5 and 6 and their similar specific impulses implies to me that Ariane 6 should have a better payload to LEO ratio, unless I'm very much mistaken. Perhaps as much as 25 metric tons for Ariane 6 versus 21 for Ariane 5. It's going to be interesting to see how eventually far off the mark I am ;)

Two more.

Note that getting rid of (expensive) common bulkheads has significantly increased the overall height of A6.

I like that Ariane family side-by-side. The 'rocket Lego' guy in me imagines a stretched A6 corestage and longer strap-on solids for an Ariane 6 derivative that can assemble basic manned lunar missions in pairs of launches...

...Or 8x stretched solids ;) But that is another story for another time... :)

We're not going to see that because there are no LEO payloads in that size class for Ariane 6 to launch.

Yes - pity they're not doing anymore ATVs for the I.S.S. :(

But a manned Lunar program could probably get their juices flowing - we've already seen mission architecture designs elsewhere for 35+plus ton LEO launchers being able to send up a spacecraft on one launcher and an Earth Departure Stage on another to do rendezvous and docking in LEO, then TLI. It's been speculated for Angara 5 and uprated Long March 5's. But that's worthy of a splinter thread to itself! We already know that Europe is interested in a 'Lunar Village' or more accurately, an Outpost.

Ariane 6 industrial organisation

In 2014, the decision of ESA Council at Ministerial level on the development of Ariane 6 was accompanied by a change in the governance of the European launcher sector, which is now based on a more balanced sharing of responsibility, cost and risk from design to exploitation by ESA and industry.

This gives industry considerably more responsibility in designing the new launcher, managing the industrial organisation, determining the needs of commercial customers and exploiting the product commercially. In turn, industry is required to contribute to the development costs and to increase its accountability in the commercial exploitation.   

The new governance approach will significantly contribute to delivering an Ariane 6 to the launch pad with the same launch capability but at 50% of the cost of the current Ariane 5.

The ESA Member States that contribute to ESA’s Launchers Programme are also involved in the manufacture of Ariane and Vega launchers. They benefit from their investment in the programme through contracts awarded to their space industry.

Most of those companies belong to each other. Background companies for 90% of that mix are only OHB, Airbus, Safran and Avio - read: the stakeholders you mention.

The only major outside subcontractors are Air Liquide (cryogenics - no surprise, they also deliver all cryogenic propellant for Arianespace launchers), RUAG (fairing - who else do you expect?) and GKN (turbines and Vulcain nozzle - has been on every single Ariane rocket for four decades).

It remains far too fragmented among many sites all over Europe each of them which can't be closed for local political reasons. By the way Indirect shareholding links among most of these companies do exist but it does not guarrantee competitve prices from subcontractors in e.g spain or Norway, as each company is in a kind of Monopoly for its specific component and protected by ESA Geographic return rules.

If you draw the same graph for Falcon or Proton, the picture would be much simpler... hence the lower prices ...

Ariane 6 on track

Quote
After a programme review completed in September, ESA is now in a position to proceed with the full development of its Ariane 6 and Vega C launch vehicles.

Today, the riders to the contracts awarded in August 2015 were signed at ESA headquarters in Paris, France. This confirms the timely continuation of the preparation of Europe’s Ariane 6 and its launch complex.

Quote
The overall value of the contracts is €3 billion. The contract amounts are: €2.4 billion for ASL and €600 million for CNES.

They cover the final full-scale development of Ariane 6 and its launch complex.

News about testing Vinci for Ariane 6 in the current DLR magazine
http://www.dlr.de/dlr/en/Portaldata/1/Resources/documents/dlr_magazin_152/DLR_Magazine_151-152_GB.pdf


LAUNCH INTO SPACE WITH A
DOWN-TO-EARTH ATTITUDE

Report on engine test for future space launch vehicle Ariane 6
By Manuela Braun

The first barriers will be set up at 10:45. The Talstrasse, which passes directly below the test
facilities at the DLR site in Lampoldshausen, is now closed to traffic at a distance of about
300 metres. And the traffic light is red at approximately 50 metres from the P4.1 test stand,
built and operated by DLR on behalf of the European Space Agency (ESA). A warning sign
dangling on the chain that stretches across the access road to the test stand reads ‘Danger
zone’ in bright red uppercase letters. “When the chain is locked: Life-threatening danger!
Major DLR test underway!” Today, liquid oxygen at a temperature of minus 183 degrees
Celsius and liquid hydrogen at minus 253 degrees Celsius will flow through feed lines, a Vinci
engine will be ignited twice in a vacuum, followed by a two-hour simulated propulsion-free
flight. In doing so, the vibrations that occur in the feed line filled with liquid oxygen will be
dampened as effectively as possible with a newly developed system. All this happens under
the space conditions that the Ariane 6 launch vehicle would endure during a flight – yet it
takes place close to the ground. The P4.1 test stand is the only one in Europe that can maintain
a stable vacuum during a test in which the engine and nozzle can operate as if at an
altitude above 70 kilometres.

Choreography of a test

“The test stand has been cleared.” Bernhard Linseisen puts down the telephone receiver. He is
responsible for ensuring that the strict safety barriers around the test stand are met during the
engine test, and ensures contact between the test director and the safety centre. Only those
who have permission from the test director and express clearance from the safety centre can
remain in the restricted area. Manuel Müller nods and reaches for his ballpoint pen. One more
item checked off the long list of around 1500 that must be completed during today’s test.
Müller is responsible for this chronology today and will therefore be test director Stefan Grunwald’s
right hand. This evening, at approximately 19:00, the last note will be added to the thick
pile of paper and the last item checked off. An engine test follows an elaborate choreography
with many participants who are each responsible for their respective fields. The chronology
ensures that no detail is forgotten and everything falls into place.

Waiting for clearance

The atmosphere in the control room is still relaxed. Since 10:00 this
morning, the engine has been covered with a special protective heat
shield, all equipment and tools from the vacuum chamber in the test
stand have been dismantled, and the heavy door of the vacuum
chamber has been closed. One of the screens in the control room
seems to show nothing – the camera is pointed at a black nozzle in a
pitch-black chamber. Only during the hot run will this screen show
something – the orange-coloured glow of the engine nozzle. While
the last preparations are underway, Grunwald is sitting next door in
the meeting room. Together with his team, he is discussing the last
measured values and the deviations from these values during the final
rehearsal with the client, the company Airbus Safran Launchers (ASL).
Green light for the planned test run will only be given if both parties
– DLR as the test stand operator and ASL as the contracting entity –
agree on the framework conditions for today’s test.

Increase from test run to test run

At 11:30, the time has come: Grunwald attaches the clearance document
to the white board in the control room. “Green light for test
M5R-12” and the signatures of the test director and client are on the
paper. The twelfth test run since April 2016 – and number 108 in
total with a Vinci engine – can begin. After the decision made at the
ESA Council meeting at ministerial level in December 2014 to develop
the Ariane 6 launcher, the previously tested Vinci engines and nozzles
were also changed. Instead of an extendable nozzle, for example, a
shorter, more compact one is now being developed and thoroughly
tested. At the DLR site in Lampoldshausen, the tried and tested P4.1
high-altitude test stand was therefore modified and adapted to the
new development targets. While a hot run without a nozzle was
carried out in the first test in order to keep the risk low, the final
configuration has meanwhile edged a bit closer with each test. Today,
several newly developed components are in the test stand, such as
the engine, the nozzle, liquid-oxygen feed line and valve, as well as a
vibration damping system.
The ‘Go’ is given. Oxygen and hydrogen are now flowing through the
test stand feed lines – it will take between two-and-a-half and three
hours until the test stand and engine have cooled down enough for
the test conditions to be reached. “LH2?” – “Tank pressure control is
running.” “What is the gas composition in the vacuum chamber?”
There is less and less background noise in the control room. Only brief
questions and answers are exchanged. Everyone is now sitting in
position as a specialist for their area and looking at the graphics and
measured values displayed on the screen. At the beginning of the
test, many things are still set manually – important in this case are the
boundary values, and the experience and instinct of the scientist.
Later, the computer will increasingly take over. Approximately 150
sequences with countless lines of code will then ensure that the
processes in the test stand are automatically and precisely executed
– and that the test is stopped if the measured values require it.

Ignite, cool, fly

The engine will run for 600 seconds after the first ignition. Shortly
before that, four steam generators will be ignited that – after a large,
three-metre-diameter flap has connected the vacuum chamber and
high-altitude system – will produce an air pressure of only a few millibars,
almost like a vacuum, in the facility for the duration of the test.
A short 120-second period follows in which the engine is purged and
cooled again before re-igniting for 60 seconds. Then, there is a twohour
‘free flight’, a so-called coast phase in which the upper stage of
the Ariane 6 rocket ‘flies’ without propulsion. The test on P4.1 should
then end with a final cooling of the engine. Approximately 900
sensors installed in the engine and test stand record pressure, temperature
and acceleration levels throughout the test. On this test day,
however, not everything will go as planned.
13:00. “Now it’s getting cold.” Today, Ralf Hupertz is the Supervisor
of the test team. He looks at two screens crammed with data, measured
values and graphics. “Now there is liquid in the lines.” “13:30,
then the next safety barrier,” Grunwald says. Linseisen informs his
colleagues in the safety centre. From this moment, the radius of the
secured zone is drawn even wider than before. The control room is
now cut off from the outside world – only voice communications with
the safety centre and fire brigade remain. It gets even quieter in the
control room. Hardly any words are exchanged across the room.
Rather, everyone is wearing headphones with radio communication.
Separated only by a thin wall, in the control room next door, sits the
team responsible for the steam generator system, which will develop
the necessary vacuum conditions just before engine ignition. The
telephone between test director Stefan Grunwald and ‘chronicler’
Manuel Müller is off the hook. During the hot phase of the test, no
telephone ringing should disturb people’s concentration or the
procedure.

System against damaging vibrations

Before the test run is initiated, the system that is used to induce a
simulated vibration onto the oxygen column within the feed line is
checked once more. In the worst case, such so-called Pogo oscillations
could occur in the resonant frequency range of the rocket. “This
could destroy the entire rocket,” says supervisor Hupertz. Even the
great Saturn V rocket, which later flew the Apollo astronauts to the
Moon, had engine failures due to these vibrations during an
unmanned test flight. The Pogo Suppression Device (PSD), which
should dampen the artificially induced vibrations in the engine above
the LOX turbopump, could later ensure that the Ariane 6 will not
have problems with this.

Delayed start-up

It is just minutes after 14:00. The 20-minute warning is heard from
loudspeakers across the entire site. But it will not be 20 minutes – the
hot run will not start for 25 minutes. The cooling criteria are only
reached after a few additional minutes. On the following day, in the
team session with the client, these deviations will be discussed in
order to set different, optimised conditions for the next test, if necessary.
The cameras now only send images from an abandoned test
stand to the screens. The only people in the immediate vicinity of the
test stand, with the engine ready for ignition, are sitting in the
protected control room. The exchange of questions and answers
starts once again. “Pressure in the vacuum chamber?” “32 millibars”
“Mass spectrometer, close valves for the hot run!” “Closed.”
The steam generators are started. On the screen, the test stand is
cloaked in more and more clouds. A muffled rumbling sound can be
heard from outside. Just a few seconds until the large vacuum control
valve is opened – and the engine can ignite. The countdown clock
over the screens jumps to zero, the engine is running in the vacuum
chamber, and the camera image changes colour – from black to
bright red. “No alarms so far.” The nozzle glows in the hot run for 10
minutes. “OK, engine cut-off,” Grunwald calls. On the screen, the
nozzle slowly darkens again.

Dealing with the unexpected

Just two minutes pass between the first and second ignitions. The
atmosphere in the control room remains tense. “Now the second
ignition ...” Grunwald’s voice is hesitant. If it takes place at all.
The planned second ignition does not happen. All eyes turn to
the measured values. No one can intervene now. Two minutes
pass – the hissing of the steam generators from outside fades and
the white cloud around the test stand slowly dissipates. Even
though the second ignition has failed, the test continues with the
planned free-flight phase and a re-cooling of the engine. It will
take about one and a half hours before the next phase starts
again at the consoles. Meanwhile, in the next room a discussion
about why the planned ignition did not take place is going on. “It
could be, for example, that the parameters for the test sequence
could not be realised for technical reasons,” Grunwald says. “The
analysis of the measured values will show this.”
At 16:35, the next 20-minute warning echoes from the loudspeakers.
Again, the test stand and engine will be cooled and the
steam generators will generate a vacuum. Today’s test will end as
soon as the Vinci engine is ready for a third ignition. Shortly
before the steam generators are supposed to start, a message
from the neighbouring control room comes through the headphones:
“We have a problem with the tank pressurisation.” The
options are clear: The steam generator team could leave the
control room once again and fix the problem on site. But that
would prolong the current coast phase. And it is not certain that
the steam generators will run. The test director nods briefly and
decides with the client: The free-flight phase will be simulated as
planned – should the steam generator not run, this would not be
decisive for the desired measurement data. Finally, the last warning
– the one-minute warning – inundates the site. And the hissing of the
steam generators starts again. “Well, it is working as planned after
all,” murmurs Ralf Hupertz.

Measurement data for the future

Felix Löhr, who is responsible for running of the automatic sequences,
looks at his screen. “LH2 is already cold.” In the chronology, Manuel
Müller is almost on the last page, checking off items, one by one.
“LOX has met two of three cooling criteria.” When the liquid oxygen
has also reached the prescribed temperature, Stefan Grunwald looks
up. “OK, then the test ends here.” The noise of the steam generators
subsides. At 17:18, the main test run is complete. All that remains is
the decommissioning of the individual test stand systems as well as
the reconditioning of the engine, which will take another 1.5 hours.
Thousands of measurement values will be analysed and evaluated on
the following day. ‘After the test’ is immediately ‘before the test’
because each result flows into the next test run. A new Vinci engine
is expected to be installed in the test stand in December 2016 – one
that will be very similar to the engine that the Ariane 6 will launch
with in 2020. The changes that come from the tested development
engine will be based mainly on one thing: today’s results from the
DLR P4.1 test stand.

Expander-cycle Technology Integrated Demonstrator

Development of the Expander-cycle Technology Integrated Demonstrator (ETID) began mid-2013. It is a major constituent of the Future Launchers Preparatory Programme (FLPP) and prepares competitive evolutions of upper stage propulsion for Ariane 6 and Vega by assembling technologies that pave the way for the next generation of cryogenic upper stage engines in Europe.

Airbus Safran Launchers and French aerospace lab Onera sign an agreement to work jointly on Lox-Methane propulsion and reusable launchers:

With the recent relaunch of a falcon 9, I'd say it's better late than never. However Ariane 6 might now be obsolete before it has even flown.

Ariane 6's first flight is planned for 2020! But we're already building the plant where we'll assemble the launcher's main stage!

There's a time lapse video with the tweet but seems to be just groundworks at this point.
