SpaceX vs Arianespace, according to the TV industry

9:11 am

The heat of competition: A television industry trade journal looks at Arianespace’s future plans and finds them wanting, when compared to SpaceX.

Compare that [SpaceX’s] success with the money that’s been poured into Arianespace, and the lack of progress (perhaps wholly understandable when being managed by a Euro-committee!). Ariane’s mid-way ME version (for Midlife Extension) has been on the drawing board since 1995. And at a considerable investment, and for an initial scheduled flight of only 2017-2018.

The Ariane-62/64 concept calls for as much of the “ME” design to be incorporated into the 62/64 versions. But the planned launch of the first A-62 is not for some time; some observers suggest at best 2021-22. That’s more than 20 years of planning, development and immense costs.

Read the whole thing. It illustrates the almost impossible challenge faced by Arianespace — a company designed by a committee of nations and run to distribute funding as widely as possible to those nations. For that company to successfully reshape its approach quickly so that it can successfully compete with SpaceX seems quite unlikely, and will likely result in Arianespace evolving into Europe’s government launch service, with the commercial market shifting back to the U.S.

Controversy surrounding IXV flight cancellation

9:24 am

Italian officials are suggesting politics or incompetence for the sudden cancellation Wednesday of the November test flight of Europe’s IXV experimental spaceplane.

ESA and CNES officials up to now have either declined to comment or, in the case of ESA, said they were at a loss to explain why a program whose mission profile has not changed in several years is now suddenly stalled for [range] safety issues that in principle should have been aired and resolved long ago.

One official, saying he could not believe that the two agencies simply forgot to evaluate the safety issues, said he preferred to suspect political motives. “Look, we are about to send a spacecraft and lander to Mars, in one year,” this official said. “Europe has rendezvoused with a comet a decade after the [Rosetta comet-chaser] satellite was launched. You want me to believe that somehow the agencies just forgot to evaluate safety? That is too far-fetched. I would rather believe there is some political motive.”

The claim is that no one ever evaluated the range issues in sending the Vega rocket to the east instead of its normal polar orbit trajectory. The Italian officials are suggesting that either the officials who cancelled the mission are incompetent, or that their competition with France within ESA over launch vehicles (Ariane 6 vs Vega) prompted the cancellation.

Europe’s lead launch-vehicle nation is France, which initially balked at participating in the Vega program. A French minister said that in Europe, launch vehicles are French. The French government declined to allow the export, to Italy, of the avionics suite that guides Vega, forcing Italy to develop its own. Italy has since done so and successfully flown it on Vega. As it stands now, one official said, France must accept the idea that with Vega, Italy has led development of a vehicle that at least in principle resembles an intercontinental ballistic missile. “Some people don’t like that,” this official said.

Either way, this cancellation combined with the difficult and extended disagreements within ESA over replacing Ariane 5 suggest that the future of this European partnership is becoming increasingly shaky.

Independent Arianespace investigation cites design error as cause of Russian launch failure

8:36 am

A just released independent investigation by Arianespace of the Soyuz rocket launch failure that put two European Galileo GPS satellites in the wrong orbits has concluded that the design of the Fregat upper stage, not an assembly error, was at fault for the failure.

The upper stage was not oriented correctly because fuel lines to thrusters had become frozen.

The freezing resulted from the proximity of hydrazine and cold helium feed lines, these lines being connected by the same support structure, which acted as a thermal bridge. Ambiguities in the design documents allowed the installation of this type of thermal “bridge” between the two lines. In fact, such bridges have also been seen on other Fregat stages now under production at NPO Lavochkin. The design ambiguity is the result of not taking into account the relevant thermal transfers during the thermal analyses of the stage system design.

That the Russian investigation found that this arrangement of feed lines happened once in every four stages that were assembled still suggests sloppiness, if not in assembly then in design. The Arianespace investigation, though thorough, thus appears to me to be trying to provide cover for thier Russian partners here.

More quality control problems in Russia

9:29 am

The investigation into the failure of a Russian Soyuz rocket to place two European Galileo GPS satellites into the correct orbit has found that it was caused by the faulty installation of fuel lines on the Fregat upper stage.

The failure was as simple as clamping together a cold helium line with the hydrazine fuel line, causing the hydrazine to freeze long enough to upset the Fregat stage’s orientation and cause the two satellites’ release into an orbit that is both too low and in the wrong inclination, officials said. One official said the Euro-Russian board of inquiry into the failure discovered that one in four Fregat upper stages at prime contractor Moscow-based NPO Lavochkin had the same faulty installation. ,,,,

Government and officials said the commission is debating how to proceed now that it knows that, as expected, the Fregat failure was not one of design, but of assembly and quality control. [emphasis mine]

In other words, 1 in 4 Fregat upper stations were routinely assembled improperly and no one noticed. The investigation also found that this assembly problem had existed on several past launches but because of the orbital requirements it had fortunately not caused any problems.

I want to emphasize that these kind of sloppy assembly issues have been occurring at a number of different Russian factories and different Russian companies. It seems to be systemic to the entire Russian aerospace industry, and it also appears to be getting worse.

Europe struggles to contain costs on its next generation rocket

9:02 am

New budget estimates for replacing Arianespace’s Ariane 5 rocket now say that they will have to include the construction of an entirely new launchpad, raising costs.

Nonetheless, Europe is trying to keep its per launch cost down and competitive.

ESA and the Airbus-Safran joint venture that proposes to manage Ariane development also floated per-launch costs that were lower than previous estimates. The lighter-version Ariane 62, with two solid-rocket boosters, could be built for as little as 65 million euros assuming a nine-per-year launch rhythm, officials said. The heavier Ariane 64, intended mainly for the commercial market and capable of carrying two satellites weighing a combined 11,000 kilograms into geostationary transfer orbit, could be built for 85 million euros each, again assuming a nine-per-year production rate.

These numbers are tiny compared to what they have charged in the past, and though higher than SpaceX’s, are within a price range that will keep them in business, assuming they can achieve them.

Europe’s satellite makers want Ariane 6

8:50 pm

Europe’s six biggest satellite makers have written Arianespace to demand that the company build its next generation Ariane 6 rocket by 2019 or face a significant loss of business.

Given the advent of electric propulsion and the dramatic launch-cost reduction offered by Space Exploration Technologies Corp., the operators say, the new Ariane 6 needs to be in service by 2019 or face the risk that Europe’s Arianespace launch consortium will be permanently sidelined. The letter was signed by six members of the European Satellite Operators Association. Signatories included the chief executives of Intelsat, SES, Eutelsat, Inmarsat, Hispasat and HellasSat.

This letter is clearly intended to help prod Arianespace into making a decision on whether to build a new rocket, Ariane 6, or upgrade Ariane 5. Right now the company’s partners have been unable to come to an agreement about what to do.

Arianespace signs four new contracts

7:37 pm

The competition heats up: As a result of lowering its prices to compete with SpaceX, Arianespace on Monday announced four new launch contracts for lighter weight commercial satellites.

At a press briefing here during the World Satellite Business Week conference, organized by Euroconsult, Arianespace said the contracts illustrate the company’s ability to win business in head-to-head competition with what has become its principal competitor, Space Exploration Technologies Corp. and the Falcon 9 rocket. Individual satellite operators choose satellite and rocket suppliers using a range of criteria including schedule, price, recent launch record and export credit-agency financing.

It was not immediately clear how many of the latest satellite wins for Arianespace followed competitions in which SpaceX offered bids compatible with customer specifications and still lost.

These satellites will be launched in the lower berth of the Ariane 5 rocket, which launches two satellites with each launch. Thus, these contracts — while encouraging for Arianespace — still leave the company with the need to find customers to fill that upper berth.

Indecision in Europe about their future commercial rocket

5:57 pm

The competition is burning them up! With Germany and France unable to come to an agreement about the next Arianespace commercial rocket, the company is considering cancelling a December conference that was supposed to settle the issue.

The basic division remains despite the German government’s alignment with the French view that Europe needs a lower-cost rocket to maintain its viability in the commercial market — which in turn provides European governments with a viable launch industry.

Despite the consensus over the longer term, the two sides remain split on whether European Space Agency governments should spend 1.2 billion euros ($1.6 billion) to complete work on a new upper stage for the existing Ariane 5 rocket, which could fly in 2018-2019, or abandon the upgrade to focus spending on a new Ariane 6 rocket, whose development would cost upwards of 3 billion euros over 7-8 years. [emphasis mine]

Though SpaceX is not mentioned in this particular article, numerous previous articles on this subject (such as this one) have made it very clear that it is SpaceX’s low prices that are driving the need for Arianespace to cut costs. The problem, as this article makes very clear, is that Arianespace’s partners can’t figure out how to do it, at least in a manner that will still provide them all an acceptable share in the pie. The result might be that the entire partnership falls apart.

Soyuz puts two satellites in wrong orbit

5:55 pm

A Russian-made Soyuz rocket launched from French Guiana for Arianespace has placed two European Galileo GPS satellites into the wrong orbit.

Russianspaceweb suggests that the problem was caused by the rocket’s Russian Fregat upper stage. (Scroll down about halfway to read their report on this launch.)

Multiple independent sources analyzing the situation suggested that the Fregat upper stage had fired its engine for the right duration, however the stage’s orientation in space during the second or both maneuvers had probably been wrong. According to Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics and a veteran space historian, the Fregat’s angular orientation error during engine firing could reach as much as 145 degrees.

This failure is a triple whammy. It hits both Arianespace and Russia since the Soyuz was part of a partnership between the two. It also hits Europe’s Galileo GPS satellite, which after many years of development was beginning to move towards full operation.

Arianespace and ESA sign contract for three launches

9:53 am

Arianespace and the European Space Agency (ESA) signed a contract on Thursday for the Ariane 5 rocket to launch 12 more of Europe’s Galileo GPS satellites on three launches.

This contract is a perfect example of European pork. Europe’s Galileo system might provide competition to the U.S. GPS and Russian Glonass systems, but I am not sure what additional capabilities it provides that will convince GPS users to switch to it. Instead, building it provides European jobs, while using the Ariane 5 rocket to launch it gives that increasingly uncompetitive rocket some work to do. In fact, this situation really reminds me of the U.S. launch market in the 1990s, when Boeing and Lockheed Martin decided that, rather than compete with Russia and ESA for the launch market, they instead decided to rely entirely on U.S. government contracts, since those contracts didn’t really demand that they reduce their costs significantly to compete.

Europe now appears to be heading down that same road.

Russian Soyuz launches commercial satellites for Arianespace

9:01 am

The competition heats up: A Soyuz rocket successfully launched four communications satellites from French Guiana yesterday.

I know that I repeatedly pound Arianespace for its high costs and lack of profits, but anyone who thinks this European company, in partnership with the Russians, is going to let its competition grab its customers easily is in for a surprise. They are going to fight back, and have the resources to do it.

The battle is on! It should be a lot of fun to watch over the next decade.
