Since last night four more launches globally

10:26 am

UPDATE: The Firefly launch was a failure. There was a problem during stage separation. See post above.

The worldwide pace of launches continues now relentlessly. Since my last launch post yesterday afternoon, there were four more launches across the global.

First, China launched a “group” of satellites for an “internet constellation,” its Long March 5B rocket lifting off from its coastal Wencheng spaceport. The rocket used a new upper stage which allowed its core stage to shut down sooner and thus not enter orbit to later crash uncontrolled (as earlier Long March 5B cores would do). Instead it fell back into the ocean after launch.

Next, SpaceX sent another 23 Starlink satellites into orbit, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida. The first stage, flying for the very first time, landed successfully on a drone ship in the Atlantic.

Third, Arianespace, the commercial division of the European Space Agency (ESA), used the Italian rocket company Avio’s Vega-C rocket to place an ESA Earth observation radar satellite dubbed Biomass into orbit, lifting off from French Guiana. This was Arianespace’s second launch in 2025. Though Arianespace managed the launch, it is being phased out. By next year all future launches of Vega-C will be sold and managed by Avio instead, cutting out this bureaucratic middle-man.

Fourth, the American rocket startup Firefly attempted to place a Lockheed Martin demo payload into orbit, its Alpha rocket lifting off from Vandenberg in California. The Lockheed Martin payload is part of a deal that could include as many as 25 launches over the next five years. This was Firefly’s first launch in 2025.

A scheduled launch by Russia of its Angara rocket on a classified military mission was apparently scrubbed, though no information at all has been released as to why the launch did not occur.

The leaders in the 2025 launch race:

50 SpaceX
23 China
5 Rocket Lab
5 Russia

SpaceX now leads the rest of the world in successful launches, 50 to 40.

Arianespace to launch Ariane-6 five times in 2025, with the first launch targeting February 26th

9:27 am

Arianespace now plans to launch the Ariane-6 rocket five times in 2025, with the first launch scheduled for February 26, 2025.

On 13 and 14 January, the Ariane 6 core stage stack and two solid-fuel boosters were successfully brought together on the ELA-4 launch pad. While this process was occurring, an Antonov transport plane touched down at Felix Eboué Airport carrying the rocket’s payload, the CSO-3 reconnaissance satellite.

This will be the first commercial payload launched by Ariane-6, a military reconnaissance satellite for France.

In addition, the Vega-C rocket is scheduled for six flights, though some of those flights might be arranged and controlled by the rocket’s Italian builder, Avio, not the European Space Agency’s commercial arm, Arianespace. Sometime in the next two years Arianespace’s responsibiilty for Vega-C is being phased out, so that Avio will own and sell all further launches.

ESA awards Avio three contracts worth $372 million for its Vega rockets

9:16 am

Capitalism in space: The European Space Agency (ESA) yesterday awarded the Italian rocket company Avio three different contracts worth $372 million to further develop its Vega family of rockets.

The first two contracts subsidize work on upgrading the Vega-C launch site at the French Guiana spaceport as well as developing the company’s planned new rocket, Vega-E.

The third contract is more significant, because it signals the coming end of Arianespace, ESA’s commercial arm. Instead of going through that government-run agency — as ESA has done for a quarter century — ESA simply bought a Vega-C launch from Avio directly, the first time it has obtained launch services directly from a European company. The contract is to place in orbit an ESA climate research satellite.

The end of Arianespace was further signaled today by the announcement that Arianespace’s chief executive since 2013, Stephane Israel, is stepping down. It was Israel who in 2015 discouraged ESA from making Ariane-6 reusable. It was Israel who for years poo-pooed competition and free enterprise, lobbying continuously that ESA should do its launches through Arianespace exclusively.

Now, more than a decade later, ESA has finally rejected Israel’s arguments, and is eliminating the middle-man Arianespace entirely, purchasing launch contracts directly from the rocket companies while having its member nations as well as itself encourage the development of many private rocket companies across Europe.

Europe’s Vega-C rocket returns to flight after being grounded for more than two years

3:47 pm

Europe’s Vega-C rocket, built by the Italian company Avio but presently still managed by the European Space Agency’s commercial arm Arianespace, today successfully completed its first launch in two years, lifting off from French Guiana carrying a European Earth observation satellite. As of posting the satellite had not yet been deployed.

The rocket was first grounded when its upper stage failed during a December 2022 launch. The investigation pinpointed the problem as the design of the stage’s engine nozzle. However, the first redesign also failed, requiring a second redesign.

This was the eighth launch worldwide in the past 48 hours, the most ever accomplished in such a short time. All told, five nations completed launches (United States 3, China 2, India 1, Russia 1, Europe 1) from eight different spaceports, with all three American launches completed by SpaceX.

Because this was only the third launch by Europe this year, the leader board for the 2024 launch race remains unchanged:

127 SpaceX
59 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 146 to 90, while SpaceX by itself leads the entire world, including American companies, 127 to 109.

Arianespace sets December 3, 2024 for the next Vega-C launch

9:17 am

Arianespace today announced that the next Vega-C launch is now scheduled for December 3, 2024, the first in more than two years since a launch failure in 2022.

The failure was caused by a design flaw in the rocket’s upper stage engine nozzle. In attempting to fix the problem, the first redesign failed as well during a static fire test in 2023. The second redesign has now passed all engine tests.

This launch — of a European Space Agency (ESA) radar satellite — is being managed by Arianespace, the commercial arm of ESA that is presently being phased out. Beginning late next year the rocket’s manufacturer, Avio, will regain complete control of its rocket and will be able to market it internationally, no longer required to deal with this unneeded government middleman. Expect the launch price to drop at that point to make Vega-C more competitive.

Avio completes testing of new redesigned nozzle for its Vega-C second stage

9:31 am

The Italian rocket company Avio yesterday successfully completed the second of two static fire engine tests of the newly redesigned nozzle for the second stage of its Vega-C rocket, paving the way for the company to resume launches after the nozzle design failed both during a launch in 2022 and then again during a static fire test in 2023 after its first redesign.

A launch date has tentatively been scheduled for November, but this date is not yet confirmed. For this and the next several launches in 2025, the rocket will still be managed by the European Space Agency’s (ESA) commercial arm, Arianespace. Beginning late next year however Avio will regain complete control of its rocket and will be able to market it internationally, no longer required to deal with this unneeded government middleman. The launch price will then certainly go down, making Vega-C more competitive.

Italian rocket company Avio outlines its future rocket plans

11:07 am

Link here. The plans include steady upgrades to its Vega-C rocket, including replacing the upper stage engine presently provided by a Ukrainian company with an engine built by Avio itself.

The bigger development will be a more powerful rocket, the Vega-E, to replace the Vega-C in 2027.

This version of the rocket will retain the first and second stages of the Vega C+ rocket and substitute the third and fourth stages for a single liquid fuel stage powered by the company’s new M10 methalox rocket engine.

The company is also hoping to begin test flights in 2026 of a Grasshopper-type small-scale demonstration rocket leading to the development of a reusable two-stage rocket that would eventually replace Vega-E.

ESA approves taking the Vega-C rocket away from Arianespace

9:12 am

The council that runs the European Space Agency (ESA) today approved a resolution that shifted ownership of the Vega-C rocket away from government-run Arianespace and giving it back to its builder, the Italian aerospace company Avio.

Arianespace and Avio have agreed that Arianespace will remain the launch service provider and operator for Vega and Vega-C launch services until Vega flight 29 (VV29), scheduled for the fourth quarter of 2025. For Vega-C launches following VV29, the customers who have already contracted with Arianespace will be offered the possibility to transfer their contracts to Avio as the new launch service provider and sole operator of Vega.

Arianespace will primarily focus with ArianeGroup on the Ariane 6 exploitation to best meet the customer needs.

The council also agreed with France’s plan to allow independent commercial rocket startups to launch from French Guiana. Control of that spaceport has also been taken from Arianespace and returned to its owner, the French space agency CNES.

Essentially, this decision ties Arianespace’s future to Ariane-6, which is likely to disappear once its present manifest of launches, mostly for Amazon’s Kuiper constellation, gets launched.

Avio completes static fire test of the upper stage of its grounded Vega-C rocket

9:03 am

The Italian company Avio yesterday completed a full static fire test of the solid-fueled upper stage of its grounded Vega-C rocket, proving that the second redesign of its nozzle now works.

The initial post-test review indicates that the new nozzle assembly performed as expected throughout the scheduled 94 seconds burning time of the test, simulating a nominal in-flight performance.

The Zefiro-40 is a 7.6 m tall rocket motor, loaded with over 36 tonnes of solid propellant. For this test the motor was installed on its horizontal test bench. Zefiro-40 is developed and manufactured by Avio in their Colleferro factory near Rome, Italy.

A second firing-test will be conducted after the summer to confirm the data collected today. Avio engineers will review the data from the first test to prepare for a second test in October that will then qualify the second stage Zefiro-40 solid rocket motor for a return-to-flight by end 2024 from Europe’s Spaceport in French Guiana.

The nozzle — originally built in the Ukraine — had failed during a launch in December 2022. Then Avio’s first redesign failed in a ground test in July 2023.

With this launch, the Vega-C is poised to resume operations by the end of the year. Those operations will be different however in one major respect. While previously the rocket was built by Avio but owned and controlled by the European Space Agency’s commercial arm, Arianespace, its ownership has been transferred back to Avio. Arianespace is now merely a “launch service provider” according to the press release. I suspect this means that Arianespace handles the launch in French Guiana, something that will also soon be taken from it because control of that spaceport is also being returned to the French space agency CNES.

A French rocket startup enters the competition

9:35 am

A new French rocket startup, Hyprspace, has assembled the engine and body of a first stage demonstrator, dubbed Terminator, to be used to test that new engine in preparation for the first suborbital test launch.

On 4 May 2024, the company shared the first glimpse of the Terminator demonstrator at its facility in Le Haillan, France. According to the update, teams had worked through double shifts over a three-week period to prepare the demonstrator for its test firing. The test will be conducted at a Direction générale de l’armement missile test facility in Gironde, France. HyPrSpace has not yet revealed when the test is expected to take place.

This engine will eventually be used in the company’s planned orbital Baguette-1 rocket for launching smallsats.

We now have at least five European rocket startups, three in Germany (Rocket Factory Augsburg, Isar, Hyimpulse), one in Spain (PLD), and one in France (Hyprspace). We also have Avio in Italy taking over ownership from Arianespace of its Vega family of rockets. That company is about to begin static fire testing a Vega-C upper stage, its engine nozzle completely redesigned following a launch failure. It hopes to resume flying by the end of the year.

ESA is taking the Vega rockets away from Arianespace and giving it to the company that builds it

9:47 am

Capitalism in space: The European Space Agency (ESA) is in the process of taking control of the Vega family of rockets away from its commercial arm, Arianespace, and returning that ownership to the Italian company, Avio, that builds those rockets.

In late 2023, ESA member states agreed to allow Avio to market and manage the launch of Vega C flights independent of Arianespace. When the deal was initially struck, 17 flights were contracted through Arianespace to be launched aboard Vega vehicles. While these missions are still managed by Arianespace, Avio is working with the launch provider to strike a deal that would allow the Italian rocket builder to assume the management of all Vega flights.

The article’s focus is on a new contract that ESA has just awarded to Vega through Arianespace. noting that this contract will likely be shifted to Avio before launch in 2025.

This decision continues the process of slowly killing off Arianespace. Instead of relying on this government entity to build and market its launch operations, ESA is instead going to become a customer only, relying on competing commercial rocket companies for its launch services. When Avio completes its takeover of Vega, Arianespace will only be responsible for the Ariane-6 rocket, which is built by ArianeGroup and essentially owns it as well. Expect that rocket to be shifted completely to ArianeGroup. At that point Arianespace will no longer have any reason for existing, and will be shut down.

ESA completes investigation of Vega-C rocket failure

5:10 pm

The European Space Agency (ESA) today released its completed investigation of December 2022 launch failure of its Vega-C rocket’s second stage.

One of the recommendations was to implement a (delta-)qualification of the nozzle with a new Carbon-Carbon throat insert material different from that previously used on the Zefiro40, the solid rocket booster of the Vega-C second stage. On 28 June 2023, a static firing test of the modified Zefiro40 engine took place at the test bench in Salto di Quirra in Italy. During the test the engine nozzle suffered significant damages.

ESA Director General Josef Aschbacher has set up an Independent Enquiry Commission chaired by the ESA Inspector General, Giovanni Colangelo, and composed of experts from CNES, ASI, ESA, Arianespace and academia to understand the cause of the test anomaly and propose recommendations.

The Independent Enquiry Commission concluded that in the current design of the nozzle, the combination of the geometry of the Carbon-Carbon throat insert and the different thermo-mechanical properties of the new material caused progressive damage of other adjacent nozzle parts and a progressive degradation eventually leading to the nozzle’s failure.

In other words, the changes implemented based on the initial investigation that was completed in March did not work. The nozzle needs to redesigned, and will also require at least two more static fire engine tests to be certified.

At the moment ESA officials are predicting that Vega-C will resume launches in the fourth quarter of next year, but do not put any money on that prediction.

ESA attributes Vega-C launch failure to faulty nozzle from the Ukraine

8:49 am

The European Space Agency (ESA) has concluded that the launch failure of the second stage of Arianespace’s Vega-C rocket on December 20, 2022 was caused by a faulty nozzle produced by a company in the Ukraine.

[T]he Commission confirmed that the cause was an unexpected thermo-mechanical over-erosion of the carbon-carbon (C-C) throat insert of the nozzle, procured by Avio in Ukraine. Additional investigations led to the conclusion that this was likely due to a flaw in the homogeneity of the material.

The anomaly also revealed that the criteria used to accept the C-C throat insert were not sufficient to demonstrate its flightworthiness. The Commission has therefore concluded that this specific C-C material can no longer be used for flight. No weakness in the design of Zefiro 40 has been revealed. Avio is implementing an immediate alternative solution for the Zefiro 40’s nozzle with another C-C material, manufactured by ArianeGroup, already in use for Vega’s Zefiro 23 and Zefiro 9 nozzles.

The press release goes to great length to reassure everyone that these Ukrainian nozzles are still flightworthy, that the fix is merely changing the material used in the nozzle’s throat insert.

South Korea officially cancels Russian launch contract, signs Vega-C instead

9:31 am

South Korea yesterday officially announced that it has canceled a Russian contract that was supposed to use an Angara rocket to launch a multi-purpose satellite last year and signed a deal with Arianespace to use the Vega-C rocket instead.

The cancellation appears directly because of the sanctions against Russia due to its invasion of the Ukraine. Picking the Vega-C as a replacement at this moment however seems a strange choice, considering its last launch was a failure and it has failed three times in the last eight launches. I suspect Arianespace gave South Korea an extremely good price.

Meanwhile, South Korean officials still seem willing to continue another Russian launch contract, using a Soyuz-2 rocket launching from Kazakhstan. According to the article, officials are right now merely negotiating a launch date.

Launch failure for Arianespace’s Vega-C rocket

8:58 am

The second launch of Arianespace’s Vega-C rocket, an upgrade from the Vega rocket that has launched previously, failed yesterday when a problem with the second stage occurred at 2 minutes 27 seconds into the flight.

Designated Vega Vehicle 22 (VV22), the rocket was the second Vega flight of the year and Arianespace’s fifth mission of 2022. VV22 was originally set to launch in November 2022, but a component in the upper composite in the payload fairing needed to be replaced. The launch failure occurred during stage 2 flight, with CEO Stephane Israel citing an “underpressure” indicated during that stage’s burn.

I have embedded video of the launch below, cued to T-30 seconds, just before launch. The rocket was carrying two Earth observation satellites built by Airbus.

The rocket itself has four stages, with the failure occurring when the second stage clearly did not maintain the rocket’s correct path. Though it appeared to be working, it was not providing enough power, so instead of continuing upward into space, the rocket fell back into the atmosphere.

France, Germany, and Italy agree on allowing competition from European rocket startups

9:02 am

Capitalism in space: France, Germany, and Italy yesterday signed an agreement [pdf] whereby they agreed to push European policy-makers to allow competition from independent European rocket startups for launch contracts.

At least, this is what I think they have agreed to. I have read the article and the agreement several times, and remain somewhat unsure of their intent. The agreement is couched in the typical bureaucratic language specifically designed to obscure meaning. The article does little to clarify things.

It appears this is the key language in the agreement:

The proposed acknowledgement of operational European NewSpace micro and mini launch systems for ESA satellite launch service procurements, upon its adoption by Council, would effectively represent a first step towards an evolution of the launch service procurement policy for ESA missions as referred to in the ESA Council Resolution adopted in 2005.

What I gather is that these three countries no longer want European launch contract awards limited to the Arianespace rockets Ariane-6 and Vega-C. They want bidding opened to all European rocket startups, and they want the elimination of rules that require all contracts distributed by quota to European countries.

Germany already has three commercial rocket startups on the verge of their first launch, and apparently wants the European Space Agency to stop favoring Arianespace in launch contracts. That France and Italy are going along with this is significant, since Ariane-6 is dominated by French developers and Vega-C is dominated by Italian developers.

Rocket Lab & ESA complete launches

8:40 am

Very early today from New Zealand Rocket Lab successfully launched the first of two quickly scheduled launches for the National Reconnaissance Office, designed to demonstrate its ability to achieve fast scheduling and rapid turnaround. The second launch is targeting July 22, 2022, only ten days later.

Also today the European Space Agency (ESA) successfully completed the first launch of its new upgraded Vega-C rocket, putting its prime payload (a passive test satellite) plus six cubesats into orbit. Though ESA says it will eventually hand over operations to Arianespace, its commercial arm, the rocket itself is mostly built by the Italian company Avio. Also, the rocket’s solid rocket first stage will be used as an optional side booster on the Ariane-6 rocket ArianeGroup is building for ESA.

Though ESA launched Vega-C, as it will eventually be managed by Arianespace I include it in that company’s total, which is now three launches for 2022.

The leaders in the 2022 launch race:

29 SpaceX
22 China
9 Russia
5 Rocket Lab
4 ULA

American private enterprise. now leads China 42 to 22 in the national rankings, and the entire globe 42 to 38.

Europe removes its science instruments from future Russian lunar missions

8:43 am

The Europe Space Agency (ESA) yesterday announced that because of Russia’s invasion of the Ukraine it will no longer fly any science instruments on three upcoming Russian unmanned lunar probes.

ESA will discontinue cooperative activities with Russia on Luna-25, -26 and -27. As with ExoMars, the Russian aggression against Ukraine and the resulting sanctions put in place represent a fundamental change of circumstances and make it impossible for ESA to implement the planned lunar cooperation. However, ESA’s science and technology for these missions remains of vital importance. A second flight opportunity has already been secured on board a NASA-led Commercial Lunar Payload Services (CLPS) mission for the PROSPECT lunar drill and volatile analysis package (originally planned for Luna-27). An alternative flight opportunity to test the ESA navigation camera known as PILOT-D (originally planned for Luna-25) is already being procured from a commercial service provider.

In other words, Europe is switching to the many private American companies that are developing lunar landers for NASA science instruments. It has also signed onto a Japanese lunar mission. All have payload space, and all are willing to take the cash of a new customer.

Meanwhile, this is how Dmitry Rogozin responded to this decision:

“Good riddance! One less European dame off our backs, so Russia should go far with a lighter load,”

To sum this all up, when it comes to space, the Ukraine invasion has been Russia’s loss, and everyone else’s gain. Even if the invasion were to end today, it will take at least a decade to re-establish Russia’s business ties with the west.

Unfortunately, the invasion will cost the Ukraine as well. In making the above announcement ESA officials also said that it is looking for alternatives to the Ukrainian rocket engines used in its Vega-C upper stage.

At the news conference, ESA also discussed the future of its small Vega rocket, which relies on Ukraine-built engines in its upper stage. The engines are manufactured by the Ukrainian company Yuzhmash, which is based in the tech city of Dnipro. Although Dnipro has been under heavy bombardment, there have been no official reports so far about damage to Yuzhmash. It is, however, clear that ESA doesn’t expect to continue its partnership with the company in the future. “We now have sufficient engines for 2022 and 2023,” Aschbacher said. “We are working on options for 2024 and onwards based on different technologies.”

Daniel Neuenschwander, ESA’s director of space transportation, added: “We are working on engine opportunities within Europe and outside of Europe, which are either tested or, even better, already existing and fully qualified.”

Whether ESA completely breaks off its partnership with the Ukraine however is not certain. Should the war continue to favor the Ukraine, then it could be that partnership will continue. Only time will tell. Right now, it is simply prudent for ESA to look for more stable alternatives.

Arianespace and SpaceX adjust to the new commercial launch market, without Russia

9:56 am

Link here. The article is mostly about how both companies need to adjust their launch schedules, with Arianespace scrambling to find rockets for its customers who had been scheduled to launch on Russian Soyuz-2 rockets and SpaceX describing how it will readjust its schedule with the addition of the OneWeb satellite launches.

The article had two quotes of interest. First, this fact about Arianespace’s new Vega-C rocket:

The Vega C uses an upper stage engine provided by Ukraine’s Yuzhmash, and supplies of that engine are in question because of the ongoing invasion. ESA officials said March 17 that they have three of those engines, enough to handle the anticipated Vega C missions this year.

ESA is supporting work on a new upper stage engine, M10, for a version of the Vega called Vega E that is slated to make its first launch around 2025. [Stéphane Israël, chief executive of Arianespace] said there was “no need” to accelerate work on Vega E, though, citing the Ukrainian engines in storage.

Thus, Vega-C is in the same boat as Northrop Grumman’s Antares, which also relies on Ukrainian rocket engines. When you also add the difficulty that both Blue Origin and ULA are having getting new rockets off the ground because of the delays in the BE-4 engine, it appears that in general there is presently a strong need across the entire rocket industry for rocket engines that is not being fulfilled by the engine builders available. This fact puts the new rocket engine company Ursa Major in a very strong position, should it begin to build bigger engines to serve this need. It also suggests there is an opportunity here for other engine builders, such as Aerojet Rocketdyne, if they have the wherewithal to grab it.

The second quote from the article of interest was from a SpaceX official, describing how the company is dealing with the sudden requirement to launch 216 OneWeb satellites:

Tom Ochinero, vice president of commercial sales at SpaceX, said at the conference that the company’s vertical integration and large fleet of reusable boosters offer the company flexibility to accommodate customers like OneWeb. “We can react very quickly because we’re just managing a fleet,” he said. [emphasis mine]

I just love the significance of the highlighted quote. Unlike all past rocket companies, SpaceX doesn’t have to build more rockets to add new customers, which makes adding new customers difficult and expensive. It simply can readjust how it uses the rockets in its fleet to get those new customers in orbit. And the new business will likely pay for SpaceX to expand that fleet so that it can launch more satellites even quicker.

New Arianespace Vega-C rocket being prepared for first launch in April

9:22 am

Engineers in French Guiana are now preparing all the components of the first Vega-C rocket, built by the Italian company Avio, for its first launch in April.

Vega-C is an upgraded version of the Vega rocket and is currently set to launch no earlier than April 2022. The rocket will feature improved first and second stage solid rocket motors, an upgraded liquid-fueled AVUM+ upper stage, and usher in an era of propulsion system commonality between the Vega and Ariane rocket lines.

At the moment they are modifying the Vega launchpad and building a new mission control center. Once completed in March they will stack the rocket.

Vega-C, like its predecessor, is powered by solid rockets, which Avio believes can be competitive with reusable rockets, at least for the next decade or so. Arianespace also hopes to lower costs by using the exact same solid rocket boosters on both Vega-C and its new Ariane 6 rocket. Vega-C’s first stage, using a P120C solid rocket motor, is also used as side boosters on Ariane 6.

ESA maps out first launch schedule for new rockets

3:19 pm

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 successfully test fires new solid rocket motor

9:11 am

Capitalism in space: ArianeGroup, the private consortium building Europe’s next generation of rockets, has successfully test fired the new solid rocket motor it will use for both its Ariane 6 and Vega-C rockets.

The P120C is designed and built by a European consortium involving a joint venture known as Europropulsion, a venture between ArianeGroup and Avio, as well as CNES, the Italian ASI space agency, and Airbus Safran. This multinational venture uses the Avio facilities in Colleferro, Italy to manufacture the carbon fiber composite casing, a facility in France to build the ArianeGroup composite steerable nozzle, and the propellant casting and integration facilities in French Guiana to build up and prepare these boosters for flight.

The P120C, through its common use across launch vehicle lines and use of existing facilities, is designed to reduce costs as a competitive response to newer companies like SpaceX that have dramatically lowered launch costs and captured an increasing share of the worldwide launch market, dethroning the ArianeGroup from the dominating position it had held until very recently.

Without doubt they are going to save money using this solid rocket motor on both rockets. I remain somewhat skeptical, however, about whether they will achieve enough cost savings to compete with SpaceX. The seeming lack of interest by their primary European customers for Ariane 6 suggests this. It appears that its price might still be too high.

ArianeGroup successfully tests solid rocket booster

10:11 pm

Capitalism in space: ArianeGroup today successfully tested the solid rocket booster that it will use on both its Ariane 6 and Vega-C rockets in the 2020s.

The test success is good news for ArianeGroup, but this quote is actually more significant:

A compromise reached in May by European Space Agency members funding launch vehicle development will keep production of the P120C in Italy, allowing Avio to produce up to 35 boosters annually. A previous arrangement would have split production between Colleferro, Italy-based Avio and MT Aerospace of Augsburg, Germany.

The economies of scale provided by using the same booster for two rockets and concentrating production in one place are a key aspect of reducing the price for Ariane 6 missions by 40 to 50 percent compared to the Ariane 5 in use today.

Faced with stiff competition from SpaceX, the European Space Agency (ESA) gave ArianeGroup the power to structure operations more efficiently rather than cater to the pork desires of the agency’s many member nations.

Whether either Ariane 6 or Vega-C can compete with SpaceX’s reusuable rockets however remains doubtful. I expect that almost all of ArianeGroup’s customers in the next decade will be ESA member nations, required to buy its more expensive services.

Europe suddenly realizes that reusable rockets are possible and economical

8:53 am

The head of the European Space Agency (ESA) has admitted in his blog that the agency’s future rockets, Ariane 6 and Vega C, are not going to be competitive because they will not be reusable.

The promise to secure autonomous access to space and reduce the price by a factor of 2 proved sufficiently compelling to secure ESA member states’ agreement to finance the development. At that time, I succeeded in placing environmental concerns and the possible development of reusability among the high-level requirements:

  • Maintain and ensure European launcher competence with a long-term perspective, including possibility of reusability/fly-back.
  • Ensure possibility to deorbit upper stage directly

Due to time and cost pressure, however, these aspects did not make it onto the agenda for Ariane 6 and Vega C. Yet in the meantime, the world has moved on and today’s situation requires that we re-assess the situation and identify the possible consequences. In many discussions on the political level, the strategic goal of securing European autonomous access to space has not changed, however there is a growing sense that pressure from global competition is something that needs to be addressed. With Vega C, Ariane 62 and Ariane 64 approaching completion, it seems logical to complete these launchers in order to at least take that major step towards competitiveness. At the same time, it is essential that we now discuss future solutions, including disruptive ideas. Simply following the kind of approaches seen so far would be expensive and ultimately will fail to convince. Totally new ideas are needed and Europe must now prove it still possesses that traditional strength to surpass itself and break out beyond existing borders. In this sense, the process of discussing and deciding on a launcher system that eschews traditional solutions can send a powerful signal out into other areas as well. I therefore intend to invite innovative, really interested European players to come together to define possible ways forward. [emphasis mine]

Let me translate his bureaucratic wording: “We didn’t think reuseable rockets were practical, economical, or even possible. We took a safe route in designing Ariane 6 and Vega C. We screwed up, and now face a competitive market in which our rockets cannot compete. Thus, we need to move fast to copy the private sector, SpaceX and Blue Origin in particular, or face serious financial consequences.

Unless he forces some major cultural changes in ESA, however, I expect that by the time this government-run operation manages to duplicate the achievements of those two private companies, those companies will have marched on to even more innovative successes.

Motor for ArianeGroup’s next generation rockets ready for testing

9:16 am

Capitalism in space: The first full scale solid rocket motor for ArianeGroup’s next generation rockets, the Ariane 6 and the Vega-C, is now ready for testing.

The P120C is the largest solid-propellant rocket motor ever built in one segment. Each P120C will hold over 140 tonnes of propellant in a carbon fibre casing almost 11.5 m long and about 3.4 m in diameter. It is derived from Vega’s current first stage motor, the P80, which holds 88 tonnes of propellant.

The design builds on existing expertise and lessons learned with Vega’s P80, and it increases Vega performance with Vega-C. Two or four P120Cs will be strapped onto Ariane 6 as boosters for liftoff.

The use of this solid rocket on both the upgraded Vega-C and the larger Ariane 6 illustrates how the privately controlled ArianeGroup is trying to reduce costs. In the past, Arianespace would have had different companies within the ESA build different solid rockets for Vega-C and Ariane 6 in order to distribute the work to different member countries, even though having two different development contracts would have increased costs.
