The core and upper stages of the first Ariane-6 rocket are now on the way to French Guiana

After almost a decade of development and delays of more than four years, the core and upper stages of Europe’s Ariane-6 rocket are now on board ship and on the way to French Guiana for that rocket’s inaugural launch.

The Canopée ship left the port of Le Havre, in France, carrying the core and upper stages of the Ariane 6 launcher which will be used on the inaugural flight. Arrival at the port of Pariacabo in Kourou, French Guiana, from where it will be transferred to Europe’s Spaceport, is scheduled for the end of February.

Once in French Guiana, the two stages will be assembled vertically and once on the launchpad, will then have attached two solid-fueled strap-on boosters. The launch window is presently from June 15th to July 31st.

ESA admits Ariane-6 will not fly until the summer of 2024

The European Space Agency today announced that the first launch of its new Ariane-6 rocket will not take place in the first quarter of 2024 and is now targeting a summer launch instead.

At a Nov. 30 briefing, ESA Director General Josef Aschbacher announced a launch period for the inaugural Ariane 6 flight of June 15 through July 31. A more precise launch date will be provided after qualification reviews in the spring of 2024. The announcement comes after a Nov. 23 long-duration test firing of a model of the core stage of the Ariane 6. That test, conducted on the launch pad at Kourou, French Guiana, was intended to simulate a full burn by the core stage.

The delay is not significant by itself, but in the large scheme of things it continues for another few months Europe’s lack of any large rockets to launch any payloads. The original plan when the Ariane-6 project was announced in the mid-2010s was for it to begin flights in 2020 with a several year overlap as the Ariane-5 was retired around 2023. As planned, the last launch of Ariane-5 occurred this summer, but Ariane-6 is now four years behind schedule.

At the moment the rocket has one more major test required, an upper stage static fire test scheduled for December. That test must go well for this new schedule to go forward, which will include a second Ariane-6 launch in 2024 followed by “as many flights as possible” in 2025. ESA hopes to do 9 to 10 Ariane-6 launches per year, most to fulfill the contract of 18 launches with Amazon to put some of its Kuiper satellite constellation into orbit.

Ariane-6’s core stage completes full 7 minute engine test

Engineers yesterday successfully completed a two-hour dress rehearsal countdown and fueling of an Ariane-6 first stage followed by a full seven minute engine burn, simulating what that stage would do during a launch.

The test took place on Ariane-6’s launchpad in French Guiana.

The November 23 test sequence was run the same way as the previous ones, with a launch sequence and final countdown representative of a launch, including removal of the mobile gantry and filling the launcher’s upper and core stage tanks with liquid hydrogen (-253° Celsius) and liquid oxygen (-183° Celsius). The test ended with the ignition of the core stage Vulcain 2.1 engine, followed by more than 7 minutes of stabilized operation covering the entire core stage flight phase. All functional aspects of Ariane 6’s core stage during the flight phase were tested.

According to the European Space Agency, only one more engine test of the Ariane-6’s upper stage remains before the spring launch can be attempted, and that engine test is planned for next month in Germany.

With the retirement of the Ariane-5 rocket in July, Europe has had no large rocket to launch payloads. Originally Ariane-6’s first launches were supposed to be in parallel with Ariane-5’s last launches, but its development is four years behind schedule.

Three European nations sign deal with Arianegroup for use of Ariane-6

In a separate deal outside of the European Space Agency, Germany, France, and Italy have signed a deal with the private rocket company Arianegroup to use its still unlaunched Ariane-6, assuming the company can reduce costs.

The agreement will provide €340 million ($365 million) of financing a year for Arianespace’s Ariane 6 rocket in exchange for a commitment to an 11% cut in costs. The rocket will also be awarded at least four missions from public institutions a year, while the lighter Vega C launcher will get at least three.

Essentially the deal is intended to keep Ariane-6 afloat, as its high cost has made it difficult to attract customers. At the same time, the contract demands those costs be reduced, and adds pressure to that demand by noting that future and additional launches will be awarded on a purely competitive bidding process. It appears these three countries will open bidding not only to the new rocket startups being developed in Europe, but American rocket companies as well.

Update on the status of Vulcan, Ariane-6, and New Glenn

Link here. This excellent article is focused on whether these three new rockets, none of which has yet completed its first test flight, will be able to meet their launch contract obligations with Amazon, which needs to launch at least 1,600 satellites of its Kuiper broadband constellation by July 2026 to meet its FCC license requirements. Those requirements also obligate Amazon to have the full constellation of about 3,200 satellites in orbit by July 2029.

The launch contracts to these three untried rockets was the largest such contract ever issued, involving 83 launches and billions of dollars.

To sum up where things stand in terms of the first test launch of each rocket:

ESA successfully test fires upper stage engines of new Ariane-6 rocket

Despite delays in test firing the first stage engines on ESA’s new Ariane-6 rocket, it has successfully tested fired the rocket’s upper stage engines in Germany.

The test of the full upper stage – including the new Vinci engine and a smaller Auxiliary Power Unit (APU) – took place on a purpose-built test bench at German Aerospace Center DLR’s engine test centre in Lampoldshausen, Germany.

Vinci, the upper stage engine of Ariane 6 fed by liquid hydrogen and oxygen, can be stopped and restarted multiple times – to place satellites into different orbits and then de-orbit the upper stage, so it is not left behind as hazardous debris in space. The APU makes it possible for Vinci to restart in space, by maintaining adequate pressure in the fuel tanks and preventing bubbles in the fuel lines. The APU uses small amounts of liquid hydrogen and oxygen from the main tanks – replacing a system which relied on large quantities of tanked helium.

A last hot-fire test is scheduled before final qualification of the Ariane 6 upper stage, with the aim of testing its operation for different types of missions, as well as in degraded conditions.

Meanwhile, the next attempt to do the same with the first stage in French Guiana is scheduled to take place on September 5th.

ESA: Ariane-6’s launch systems tests “progressing well”

According to a press release today from the European Space Agency (ESA), tests of the launch systems for its new Ariane-6 rocket are “progressing well”, though this particular test program was unable to finish its launch countdown rehearsal on July 18th with an actual static fire engine test of the rocket’s first stage engine.

The launch simulation included the removal of the mobile gantry, the chill-down of ground and launcher fluidic systems, the filling of the upper and core stage tanks with liquid hydrogen (–253°C) and liquid oxygen (–183°C), and at the end of the test, the successful completion of a launch chronology up to the ignition of the Vulcain 2.1 engine thrust chamber by the ground system.

During the 26-hour exercise, the teams successfully tested many degraded and contingency modes, demonstrating that the launcher and the launch base fit correctly. Operational procedures, lower and upper stages, avionics, software, launch base and control bench worked correctly together, and the performance of the full launch system was measured with excellent results.

The last part of the test – a short ignition of the Vulcain 2.1 engine – had to be postponed to the next test session as time ran out. The teams are now working towards continuing the exercise, in preparation for a long duration hot firing test later this summer. [emphasis mine]

The highlighted words imply a certain leisureliness on ESA’s part, an impression that might be wrong but it is the impression this language gives out. One wonders why the launch countdown could not have been completed to that static fire engine burst. “Time running out” seems a very lame reason, especially since ESA no longer has the Ariane-5 rocket and the Ariane-6 to replace it is years behind schedule.

Europe successfully tests rocket engine to be used in its first reusable rocket

The European Space Agency (ESA) on June 22, 2023 successfully completed a 12-second static fire test of the Prometheus rocket engine it plans to use in its first reusable rocket.

The engine, like SpaceX’s Raptor-2 engine for Starship/Superheavy, uses methane as its fuel. The plan is to use it in a future rocket to replace or upgrade the Ariane-6 rocket, still being developed, with the ability to vertically land and reuse the first stage. The plan after this first round of static fire tests is complete is to begin to do short vertical hop tests next year, similar to the Grasshopper tests SpaceX did as it developed the Falcon 9.

However, the following quote from the article indicates their are some limitations to the engine:

According to CNES, the new engine will be reusable up to five times and can deliver variable thrusts of up to 100 tonnes.

SpaceX builds its Merlin and Raptor engines with the goal of many more reuses than this. Possibly this number is simply a conservative estimate that will change once the engine is operational. If all goes as planned, ESA hopes to have this new reusable rocket flying by 2026, at the earliest.

Ariane-6 engineering test rocket at launchpad for engine tests

Ariane-6 test version at launchpad
Click for original image.

An engineering test version of ArianeGroup’s Ariane-6 rocket has arrived at the launchpad in French Guiana, where it will undergo a series of static fire engine and fueling tests.

As seen in this image [to the right] taken on 22 June 2023, the doors of this mobile gantry have been opened and the structure rolled back on rails. The operation, which takes about half an hour, was a trial run in preparation for a series test firings of the Vulcain 2.1 engine. These test firings will be conducted on the launch pad as part of ongoing preparations for the first-ever flight of Ariane 6. Removing the gantry for the first time – and then returning it – also helped validate the Ariane 6 ground infrastructure.

The Ariane 6 rocket visible here is not intended for flight. It is being used to check assembly procedures, electrical and fuel connections, telemetry, etc. Flight models, including the rocket that will make Ariane 6’s inaugural flight, are being built in Europe and integrated by prime contractor Ariane Group. After shipping to French Guiana, Ariane 6 core and upper stages are assembled horizontally, before being transferred to the launch pad and lifted upright inside the gantry, where the solid-fuel boosters and payload are attached. The horizontal assembly method cuts the time and cost of a launch campaign, and is a first for an Ariane rocket.

With only one Ariane-5 rocket launch left on its manifest, the European Space Agency desperately needs to get Ariane-6 off the ground and operational. It was originally supposed to make its first launch in 2020, thus overlapping the final launches of Ariane-5 by several years. At this moment it appears there will be a gap between when one rocket retires and the other begins flying.

Ariane-6’s first launch now likely delayed again, until 2024

According to officials from the German company OHB, which makes parts of Europe’s new Ariane-6 rocket, its first launch will not take place before the end of this year, as presently scheduled by Arianespace, the commercial arm of the European Space Agency (ESA).

In a May 10 earnings call, executives with German aerospace company OHB predicted that the rocket will make its long-delayed debut within the first several months of 2024, the strongest indication yet by those involved with the rocket’s development that it will not be ready for launch before the end of this year.

“It’s not yet launched, but we hope that it will launch in the early part of next year,” said Marco Fuchs, chief executive of OHB, of Ariane 6 during a presentation about the company’s first quarter financial results. A subsidiary of OHB, MT Aerospace, produces tanks and structures for the rocket. Later in the call, he estimated the rocket was no more than a year away from that inaugural flight. “I am getting more and more confident we will see the first launch of Ariane 6 early next year,” he said. “I think we are within a year of the first launch and that is psychologically very important.”

These delays seriously impact many projects of ESA and other European companies. Ariane-6 was originally supposed to launch by 2020, overlapping the retirement of its Ariane-5 rocket by several years. Ariane-5 now has only one launch left, presently scheduled for June. Once that flies, Europe will have no large rocket available until Ariane-6 begins operations. This situation is worsened for Europe in that its other smaller rocket, the Vega-C, failed on its last launch and has not yet resumed operations.

It is not surprising therefore that many European projects have been shifting their launch contracts away from Ariane-6 to SpaceX and others. It is also not surprising that there is now an increasing move in Europe to develop new competing private rocket companies, rather than relying on a government-owned entity like Arianespace.

Viasat drops launch contract with Ariane-6

With SpaceX’s Falcon Heavy having just completed the first of three launches for Viasat’s new geosynchronous constellation of communication satellites, the satellite company has announced that it is cancelling its launch contract with Ariane-6 for the third launch.

The decision means the launch contract is up for grabs for the third ViaSat 3 internet satellite, the last of a three-satellite constellation Viasat is deploying to provide global broadband connectivity from space.

Viasat announced in 2018 it selected SpaceX, United Launch Alliance, and Arianespace to each launch one ViaSat 3 satellite, awarding launch contracts to three industry leaders.

The ULA launch, on its Atlas-5 rocket, is still scheduled for either late this year or early next.

The development of Ariane-6 however is years behind schedule. Furthermore, Arianespace has given priority on Ariane-6 to all of the ESA launches that formerly were going to be launched on Russian Soyuz rockets, further delaying Viasat’s launch.

For Viasat, the delays have become unacceptable, and it has now opened that third launch to bidding. Though both ULA’s Vulcan and Blue Origin’s New Glenn rockets could do the job, neither is operational either. It appears SpaceX’s Falcon Heavy is the only rocket available and is therefore almost certain to get the contract, a conclusion further confirmed by the timing of this announcement, just prior to that successful Falcon Heavy launch.

ESA delays first Ariane-6 launch to late in 2023

The European Space Agency has once again delayed the first Ariane-6 launch, shifting it to the fourth quarter of 2023.

Even so, officials warned that this is merely “a planned date,” and that static fire tests of both the first stage and second stage must first be completed before the launch can go forward.

Ariane-6 was initially supposed to begin launching in 2020, putting it three years behind schedule. Furthermore, it has struggled to obtain customers, as it is entirely expendable and thus expensive and not competitive with SpaceX’s Falcon 9.

Since Ariane-6 is delayed and the Ariane-5 rocket’s has only a few launches left before retirement, ESA officials also noted that it has now been forced to buy two launches from SpaceX.

The launches include the Euclid space telescope and the Hera probe, a follow-up mission to NASA’s DART spacecraft which last month succeeded in altering the path of a moonlet in the first test of a future planetary defence system. “The member states have decided that Euclid and Hera are proposed to be launched on Falcon 9,” ESA Director General Josef Aschbacher told reporters after a meeting of the 22-nation agency’s ministerial council.

The launches will take place in 2023 and 2024 respectively.

The irony is that ESA is probably going to save a lot of money launching with the Falcon 9, rather than its own Ariane-6. In fact, I would not be surprised if the total SpaceX price for both launches equals one Ariane-6 launch. Furthermore, SpaceX gets this business because its own American competitors, ULA and Blue Origin, have also failed to get their new rockets flying on time.

Ariane-6 mock-up installed at launchpad for tests

The European Space Agency yesterday announced that it has installed an Ariane-6 full scale mock-up at its launchpad in French Guiana in preparation for tank and launch procedure tests.

The Ariane 6 combined tests model is highly representative of the flight model. It consists of the core stage and the upper stage, which make up the central core, as well as three pylons shaped like the rocket’s solid boosters and a fully representative but inert mockup of the fourth booster.

The Ariane 6 combined tests model central core was precisely mated in the purpose-built launcher assembly building, where this task is carried out horizontally. Automated guidance vehicles then brought the assembled core to the launch and, working with the crane at the mobile gantry, raised it to its vertical position.

The date of the actual first launch has not been announced, though ESA has officially admitted that it will not occur this year as hoped.

ArianeGroup chosen by Europe to develop reusable rockets

The new colonial movement: The European Commission, which makes the major decisions for the European Space Agency, has chosen the European commercial company ArianeGroup to run two programs designed to produce that continent’s first reusable rocket.

From the press release [pdf]:

The SALTO project will facilitate the first flight tests of the Themis reusable stage demonstrator in Kiruna, Sweden. The ENLIGHTEN project will speed up the development and introduction of reusable engine technologies.

The main goal of SALTO will be to develop the kind of vertical landing technology that SpaceX now does routinely. ENLIGHTEN in turn will develop rocket engines using either methane or hydrogen as the fuel. The total budget allocated for both is just under 50 million euros, which seems quite small. The press release also made no mention of a schedule for accomplishing these tasks.

Ariane-6 rocket delayed again

Capitalism in space: The first launch of ArianeGroup’s new rocket, Ariane-6, has been delayed again, and will not launch this year as planned.

The new delay appears mostly related to getting the rocket’s ground systems up and running.

The rocket, being built for the European Space Agency’s commercial division, Arianespace, had originally been scheduled for launch in 2020. Initially the rocket struggled to find customers, because it is not reusable and is thus more expensive. That changed in the past few months with the Ukraine War eliminating Russian rockets as a competitor combined with a new gigantic launch contract from Amazon to launch a large number of its Kuiper satellites using Ariane-6.

ESA selects Ariane-6’s first payloads

The European Space Agency (ESA), ArianeGroup, and Arianespace today announced the payloads that will fly on the first launch of its new Ariane-6 rocket.

The payloads are a variety of cubesats and science experiments, none heavier than 175 pounds with a total payload weight less than one ton. These secondary payloads will either be deployed from or kept attached to a dummy mass that will simulate a large primary satellite payload.

The press release makes no mention of a launch date, as has been the pattern in the last few Ariane-6 press releases. The last release to mention a launch date was in October 2020, which then predicted a launch in the second quarter of ’22. That this date is no longer being mentioned suggests the date has been pushed back, though for how long remains a mystery.

Ariane-6 finally wins more launch contracts

Arianespace today announced a new slew of launch contracts, including two for its mostly Italian-built Vega rocket family and four for its Ariane family of rockets.

The latter launch contract is significant as those four launches, putting eight more Galileo GPS-type satellites in orbit for the European Union over the next three years, will all be launched by Arianespace’s new Ariane-6 rocket, built and owned by the commercial company ArianeGroup.

The significance is twofold. First, Ariane-6 has struggled to get launch customers because its launch cost is far higher than SpaceX’s, to a point that the low number of contracts weren’t paying for the cost of development. This new contract overcomes that difficulty by adding four more launches.

Second, the nature of all of Ariane-6’s contracts underscore the difficulties it is having. Before the arrival of SpaceX’s mostly reusable and very inexpensive Falcon 9 rocket, Arianespace held 50% of the market share for commercial launch contracts, using its Ariane-5 rocket. Those customers have mostly vanished, however, switching to SpaceX. Ariane-6 was conceived — by the government-run European Space Agency — as a newer cheaper rocket that would recapture some of that market. All of its launch contracts, both old and new, demonstrate that it is failing to do so, however. Its only customers so far are coming from European government entities, who are required to use Ariane-6 as part of their partnership in the European Union and the European Space Agency. No private concern, inside or outside Europe, seems interested in using Ariane-6. It just costs too much.

For Europe to compete in the new commercial launch market it needs to build better rockets. And to do this it needs to release its rocket industry from the control of government.

ArianeGroup ships the 1st Ariane-6 core and upper stages to French Guiana

Capitalism in space: ArianeGroup today announced that the first completed stages for its new Ariane-6 rocket have been shipped to French Guiana for testing.

The Ariane 6 core stage and upper stage intended for the combined tests on the launch pad in French Guiana have left the ArianeGroup sites in Les Mureaux and Bremen and begun their journey to Europe’s Spaceport. These stages will be integrated by ArianeGroup in the Launcher Assembly Building (BAL) to create the central core for the Ariane 6 combined tests model.

The press release provided no information on the schedule for the tests or the first launch. An earlier release had targeted the second quarter of ’22 for the inaugural launch, but based on today’s press release I would suspect that scheduled is very tentative.

This press release marks another major change in how Europe will launch rockets. No longer is the government-run Arianespace in charge. Instead, the commercial partnership of Airbus and Safran, dubbed ArianeGroup, is running things. In exchange for building this new rocket this partnership demanded a greater share of the profits and full control, something the European Space Agency (ESA) had denied them under Arianespace. This new arrangement was devised in the hope it would give this private partnership a direct interest in making a profit, thus cutting costs and encouraging innovation.

However, because ESA is still very very closely involved in every step, it is uncertain whether this arrangement will achieve its goals. Moreover, there are indications that ArianeGroup itself is somewhat risk adverse. For example, in designing Ariane-6 both decided to forego re-usability. Their rocket is thus more expensive than SpaceX, and has had trouble garnering launch contracts.

Ariane 6 inaugural launch date appears to be delayed again

It appears that officials at the European Space Agency (ESA) have begun preparing the public for a further delay in the first launch of its new Ariane 6 rocket, from the second quarter of 2022, as announced in October 2020, to the third quarter of 2022, at the earliest.

Josef Aschbacher, director general of the European Space Agency, at the Paris Air Forum [described the creation of] “a small group” … to make an independent assessment of the schedule for the final development phase of the Ariane 6 rocket. The goal of this task force will be to ensure that Europe does everything it needs to do launch on time.

…In referring to an “on time” launch, Aschbacher said he meant next year, before the European Space Agency’s Ministerial Council meeting that is typically held in October or November. This is a high-level meeting where representatives from each member nation of the space agency gather to set policy. The European Space Agency’s budget is provided, in varying amounts, by member nations. “This is a must,” Aschbacher said of launching before the 2022 meeting, “because we need good news, and good success, for our politicians to see that Europe performs, that Europe delivers, and therefore it is worth investing in space in the ministerial conference.”

It appears from these statements that the development of Ariane 6 is now faced with delays that might make a launch by the third quarter in ’22 difficult, and this new independent committee is being put together to try to forestall that possibility. What makes this even more significant for Ariane 6 is that it continues to have trouble winning contracts from the nations within ESA, as it remains far more expensive that SpaceX’s Falcon 9. If that first launch is delayed past that important fall ’22 high-level meeting, those politicians at that meeting might decide to consider serious new alternatives to it, or even more drastically decide to replace it entirely.

ESA funds ArianeGroup prototype vertical landing hopper

The European Space Agency (ESA) has now committed 33 million euros for ArianeGroup to develop a prototype vertical landing hopper dubbed Themis that would begin testing first stage landings by ’23.

ArianeGroup and its collaborators in Belgium, Switzerland, France and Sweden offer critical technical knowhow gained through the development of Europe’s next-generation engine – Prometheus – which will power Themis.

ESA’s Prometheus is a highly versatile engine capable of providing 1000 kN of variable thrust and is reignitable which makes it suitable for core, booster and upper stage application. An onboard computer handles engine management and monitoring in real time – a crucial feature for reusability.

ArianeGroup is the private consortium led by Airbus and Safran that is building Ariane 6. This deal suggests that ESA amd ArianeGroup has finally recognized that Ariane 6, built without reusability, is a lemon and is not attracting customers. This new contract starts the process of developing a reusable first stage.

They still might be too late. They will only begin testing the Themis prototype in ’23, with no clarity on when a full scale version will follow. Meanwhile, it is very likely that SpaceX’s fully reusable Starship/Super Heavy will be flying orbital missions by then, and likely charging far less than they presently do for their Falcon 9.

ESA maps out first launch schedule for new rockets

Capitalism in space? The European Space Agency (ESA) today laid out the development roadmap that will lead to the launch of two new rockets, the Vega-C being built by the Italian company Avio, and the Ariane 6 being built by ArianeGroup.

The Vega-C is a more powerful version of the Vega rocket, aimed at capturing the smaller satellite market. It maiden flight is now scheduled for June ’21.

The Ariane 6 is aimed at replacing the Ariane 5, Europe’s big workhorse rocket, but to do so at a lower cost. Its maiden flight is now set for the second quarter of ’22, a significant delay from the previously announced target date in ’21, which itself was a delay from the original late ’20 launch date.

Ariane 6 however has not succeeded in cutting costs enough to match its competitor SpaceX, and thus it continues to have trouble attracting customers, even among ESA’s partner nations that it is meant to serve. These issues have led to rumors that ESA is already looking to either significantly upgrade Ariane 6 (before it even flies), or replace it entirely wit a new re usable rocket.

ArianeGroup completes testing of all three Ariane 6 rocket engines

Capitalism in space: ArianeGroup, the joint private partnership that is building Europe’s new Ariane 6 rocket, has successfully completed all testing of the three different engines the rocket will use.

The first stage has a core engine with side strap-on solid rocket motors, while the upper stage has a different engine entirely. All three have now passed qualification tests, allowing full design and construction of the rocket itself.

COVID-19 and launchpad issues delay Ariane 6

The European Space Agency (ESA) confirmed today that the first launch of Arianespace’s Ariane 6 rocket will be delayed at least six months, to late 2021, due to lock downs related to the Wuhan flu panic, as well as construction issues at the rocket’s new launchpad.

“While we know that the maiden flight will not take place before the second semester of 2021, we cannot at this moment precisely quantify the delay, and we cannot provide an exact launch date,” Daniel Neuenschwander, ESA’s director of space transportation, said according to an ESA translation of remarks at a July 9 press event provided to SpaceNews. The French Association of Professional Journalists in Aeronautics, organized the event at ArianeGroup’s headquarters in Paris.

ESA hopes to have greater clarity on the delays in a few months, he said, according to the ESA translation.

It bodes bad for this rocket that they, at this time, have so little handle on the issues and the length of the delays.

ArianeGroup developing new rocket engine

Capitalism in space: The private company ArianeGroup has now gotten the okay from the European Space Agency (ESA) to begin full development of its new Prometheus rocket engine, intended to reduce costs 10x.

By applying a design-to-cost approach to manufacturing Prometheus, ESA aims to lower the cost of production by a factor of ten of the current main stage Ariane 5 Vulcain 2 engine. Features such as variable thrust, multiple ignitions, suitability for main and upper stage application, and minimised ground operations before and after flight also make Prometheus a highly flexible engine.

This Prometheus precursor runs on liquid oxygen–methane which brings high efficiency, allows standardisation and operational simplicity. Methane propellant is also widely available and easy to handle.

Essentially, ArianeGroup is going to try to build its own methane-powered rocket engine, having seen the success that SpaceX has so far had with its own Raptor methane engine. This also signals an increased recognition at ESA and ArianeGroup that their new Ariane-6 rocket, whose first launch is still about a year away, is not going to be competitive with SpaceX’s offerings, and needs to be upgraded or replaced.

First Ariane 6 launch likely delayed to 2021

Because of delays caused by the Wuhan flu panic, the European Space Agency (ESA) and ArianeGroup now expect that the first launch of their new rocket, the Ariane 6, will likely be delayed from late in 2020 to 2021.

The loss of the flight’s payload is also a problem.

Finally, megaconstellation startup OneWeb had booked 30 small broadband satellites on the Ariane 6 maiden flight, but filed for Chapter 11 bankruptcy protection in March, putting the mission in question. Luinaud said if Arianespace can’t find another customer for the Ariane 6 maiden flight this year, it may wait until 2021 to find a payload and avoid flying the rocket empty.

Overall Ariane 6 has been having trouble getting customers. Though it is less expensive that the Ariane 5, it it is entirely expendable and thus remains much more expensive than SpaceX’s Falcon 9. And with the Russians slashing the price of their Russia Proton rocket satellite companies have ample other options. It is for this reason I do not expect Ariane 6 to stick around long. ESA will be quickly forced to replace it with something less expensive and probably reusable.

Europe turns to private enterprise for future space transportation

Capitalism in space: The European Space Agency (ESA) has announced a permanently open call for private companies to develop “space transportation to space, in space, returning from space, or any combination of these.”

To be eligible, the economic operator should demonstrate that its space transportation service is a ‘complete offering’. This means that customers should not need to procure any additional essential service elements such as access to facilities, transport or logistics, to obtain the full service.

The economic operator should take full responsibility for the service project, including finding the funding and resources necessary to develop and deploy the service.

The new space transportation services should justify commercial viability, oriented toward private sector customers, without relying on a guaranteed European institutional demand during the operational phase and with a long-term vision of service provision. Preference will be given to such service projects that are conceived, developed and commercialised in the Participating States.

Though the announcement is filled with the typical hard-to-translate bureaucratic language typical of ESA’s projects, the intent here seems clear. The ESA no longer wishes to do any designing and developing of its rockets, as they have done from the beginning of the space age. This also means they are facing the reality that the Ariane 6 rocket, developed for them by the joint partnership of Airbus and Safran dubbed ArianeGroup, is going to be a financial failure, unable to compete against the lower cost SpaceX and Russian rockets now on the market.

Instead, they are now following what appears to be NASA’s path — the path I outlined in Capitalism in Space — to have ESA act merely as a customer, buying these services from competing private companies (not just ArianeGroup) who will develop the rockets themselves and (most important) own the rockets themselves.

If this is so, it is very good new for the future of space travel. It ups the competition, and it will allow for the development of European rockets able to provide this service at low cost.

The one wrench in the process is that this announcement also includes a bidding process for allowing these new private companies to get development money and technical assistance from ESA. That process appears to have some strings attached that might in the end prevent competing private companies to grow, independent of this governmental body. For example, the submission process allows “ESA to check compliance with Programme objectives and general eligibility. After a positive assessment, ESA will invite the economic operator to submit a full service proposal.” In other words, if you want ESA’s help, you will have to have ESA’s stamp of approval.

Still, this proposal does not require ESA’s help. The agency does appear to be willing to now entertain the use of any rocket system developed by any private operators within the participating ESA’s member nations of Germany, Italy, Norway, Portugal, Romania, Sweden and the United Kingdom.

Airbus to cut 2,362 jobs, citing weak space market

Capitalism in space: Airbus announced this week that it plans to cut 2,362 jobs, citing as the reason “lower performance in space” as well as postponed defense contracts.

This quote from the article is revealing:

Airbus Defence and Space is the third satellite manufacturer to announce layoffs in the past 12 months. Thales Alenia Space said in September it was cutting around 6% of its workforce, following Maxar’s February 2019 announcement that it would dismiss roughly 3% of its employees.

The article however also indicates that 2019 saw a big recovery in geosynchronous satellite orders.

Though not stated, I suspect that part of Airbus’s problem is related to Ariane 6, which it is building in a joint partnership with Safran dubbed ArianeGroup. While designed to be less expensive to build, the rocket is not reusable, and its launch price is simply not competitive. Thus, getting contract orders has been very difficult.

Note also that ArianeGroup announced in November 2018 that it going to cut 2,300 jobs by 2022. I wonder if some of these cuts overlap the newly announced cuts.

Either way, these trims might be a good thing as Airbus and ArianeGroup work to cut their costs. Or they could be a bad thing, indicating that both are having trouble making sales. Only time will tell.

Europe completes 1st rollout of Ariane 6 mobile launch gantry

The mobile launch gantry that Europe will use for its new Ariane 6 rocket successfully completed its first rollout tests last week.

This gantry is the equivalent of NASA’s VAB building. Within this gantry they will assemble Ariane 6 vertically, then roll the gantry back for launch.

Assembling a rocket vertically I think is more costly, but it also makes it possible for the rocket to launch payloads that must be installed in this manner. Thus, Ariane 6 will have this selling point over rockets like the Falcon 9 and Falcon Heavy, which are assembled horizontally.

ArianeGroup begins production of first 14 Ariane 6 rockets

Capitalism in space? ArianeGroup has announced it has begun production of the first fourteen Ariane 6 rockets, set for launch beginning in 2020.

Following the initial institutional and commercial launch orders for Ariane 6 obtained by Arianespace since the autumn of 2017, and the resolution of the ESA Council on April 17, 2019, related to the rocket’s exploitation framework, ArianeGroup is starting to build the first series-production batch of 14 Ariane 6 launchers.

These 14 launchers, scheduled to fly between 2021 and 2023, will be built in ArianeGroup plants in France and Germany, as well as in those of its European industrial partners in the 13 countries taking part in the Ariane 6 program.

The April 17 resolution essentially committed the ESA (European Space Agency) to subsidize ArianeGroup should Ariane 6 fail to obtain sufficient launch contracts for the company to make a profit.

Right now, that subsidization seems almost certain, based on the prices ArianeGroup is charging for Ariane 6 and the resulting dearth of sales contracts.

The launch rate announced above illustrates the rocket’s lack of interest. Fourteen launches in three years? SpaceX has been launching that many times in half a year. Granted, Ariane 6 is designed to launch two satellites to Falcon 9’s one, but even so this launch rate is low. And I expect in reality it will be lower than this. I expect them to fail to get launch customers, and will find they have a white elephant on their hands.
