Test flight of Europe’s first prototype space plane has been rescheduled

9:55 am

The competition heats up: Preparations have resumed for a February 11 test flight of a European prototype space plane, initially scheduled for November but cancelled at the last minute because managers suddenly discovered its launch path was going to go over land.

The launch trajectory of the IXV space plane on a suborbital trajectory will differ from the Vega rocket’s previous flights, which flew north from the space center with satellites heading for high-inclination polar orbits. The launch of IXV will head east from Vega’s launch pad, and the geometry of the French Guiana coastline means it will fly over land in the first phase of the launch sequence.

Officials said they slightly adjusted the launch track to alleviate the the safety concern.

The four-stage Vega rocket was stacked on the launch pad at the Guiana Space Center, and the IXV spacecraft was about to be fueled with hydrazine maneuvering propellant when officials announced the delay in October. A ship tasked with retrieving the space plane after splashdown in the Pacific Ocean had already left port in Italy when news of the launch delay was released.

I remain suspicious about the cause of the delay in November. How could they not have known about the launch trajectory until the last second? Instead, I suspect it occurred because of politics higher up in ESA related to Italian, German, and French tensions over the future of Arianespace. The Italians are the lead on this space plane project, to the apparent chagrin of the French, who mostly run the launch facility in French Guiana. Moreover, it appears the Italians have generally sided with the Germans against the French in the Ariane 6 design negotiations. I wonder if the delay was instigated by higher management in an effort to influence those negotiations.

Airbus-Safran demand total control of Arianespace

9:00 am

The heat of competition: The European joint-venture between Airbus and Safran is now demanding that be given total control of Arianespace and the development of the new Ariane 6 rocket.

From Airbus’ perspective, the production of rockets in Europe should be done the same way commercial Airbus aircraft are built. “The launcher business in Europe in the beginning of 2014 was one in which the vehicles were designed by government agencies, commercialized by a company called Arianespace, produced by an ensemble of companies, and then launched by Arianespace. This is not an optimal situation,” [Airbus strategy director Marwan] Lahoud said.

“The optimal solution is to industrialize the process, with one prime contractor that designs, builds, sells and operates the launchers, with a supply chain — much as we do with Airbus today.”

Essentially, this would be a shift in ownership of the rocket, moving from the government to the private company. We have seen the same process in the U.S., with the new commercial space products no longer controlled or designed by NASA. The result has been lower cost, faster development, and greater profits.

Europe reconsiders reusability in its rockets

8:45 am

The competition heats up: Pressured by SpaceX, Europe has restarted a research program into developing a reusable first stage to its rockets.

The headline is actually an overstatement. The European managers quoted in the article actually spend most of their time explaining why trying to reuse a rocket’s first stage makes no sense, but they feel forced to reluctantly look into it anyway because of what SpaceX is doing with its Falcon 9.

This story makes me think of two blacksmiths around 1900. One poo-poos cars, saying that the repair cost is so high no one will ever buy them. He goes back to pounding horseshoes. The other decides that if he learns how to fix cars, he can turn his shop from fixing horseshoes to fixing cars, and make more money. Europe is the first blacksmith, while SpaceX is the second.

Which do you think is going to succeed?

Airbus attacked by French lawmaker for talking to SpaceX

8:56 am

The competition heats up: A French lawmaker lashed out at Airbus for daring to consider SpaceX as a possible launch option for a European communications satellite.

The senator, Alain Gournac, who is a veteran member of the French Parliamentary Space Group, said he had written French Economy and Industry Minister Emmanuel Macron to protest Airbus’ negotiations with Hawthorne, California-based Space Exploration Technologies Corp. for a late 2016 launch instead of contracting for a launch on a European Ariane 5 rocket. “The negotiations are all the more unacceptable given that, at the insistence of France, Europe has decided to adopt a policy of ‘European preference’ for its government launches,” Gournac said. “This is called playing against your team, and it smacks of a provocation. It’s an incredible situation that might lead customers to think we no longer have faith in Ariane 5 — and tomorrow, Ariane 6.”

Heh. SpaceX really is shaking up the launch industry, ain’t it?

New joint venture to build Ariane 6

9:42 am

Faced with stiff competition from SpaceX, Europe has handed the construction its next generation rocket, Ariane 6, from Arianespace to a joint venture between the European companies Airbus and Safran.

The new venture will be dubbed Airbus Safran Launchers, and will take over as Europe’s launch company.

I had known that Airbus and Safran had proposed this venture to build Ariane 6, but until I read this press release I hadn’t realized that the agreed-to deal to build Ariane 6 means that Arianespace has essentially been fired by Europe as the company running Europe’s rocket operations. Arianespace, a partnership of the European Space Agency’s many partners, was never able to make a profit, while its Ariane 5 rocket costs a fortune to launch. They have now given the job to two private companies who have promised to rein in the costs. We shall see what happens.

Europe approves construction of giant telescope

9:17 am

Europe has approved the construction of the European Extremely Large Telescope (E-ELT), which when completed will be the largest ground-based telescope.

The E-ELT will have a mirror 39 meters across, almost four times bigger than the world’s largest telescope today.

A word to the wise: This very month Sky & Telescope’s cover article, written by yours truly, describes the many difficulties the world’s present generation of giant telescopes have faced. Four out of five have not produced the science promised. Two of the four were dogged by so many technical problems that they required complete reconstruction. The builders of E-ELT will face even greater engineering challenges. Do not be surprised if this telescope does not get completed by 2025 as promised, and even if it does, do not be surprised if it takes another half decade or more before the engineers work out all the kinks.

Europe agrees to build Ariane 6

8:01 am

The heat of competition: Faced with a stiff challenge from SpaceX, the European partners in Arianespace have worked out a deal to replace the Ariane 5 rocket with Ariane 6.

The official announcement will be made in next few days, but with Germany agreeing to the French proposal, the partnership can now proceed.

The result will be a government rocket which will likely only launch government payloads, since it will likely also cost too much to compete with SpaceX and the other new lower cost commercial companies like Stratolaunch, now developing in the U.S.

Italy’s legislature rejects additional funding for space

12:11 am

The Italian legislature has refused to add an additional $250 million to the budget of its space program, money requested to help pay the country’s share in the development of Arianespace’s next generation commercial rocket, Ariane 6.

The money was also needed for several other ESA space projects. Not having it puts a question mark on Italy’s future in space. The article also illustrates how the committee nature of Europe’s cooperative space effort makes it almost impossible for it to compete in the commercial market.

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.

The November 12 timeline of events for Philae’s landing on a comet

10:16 am

ESA has released a detailed timeline of events on November 11-12, when Rosetta’s Philae lander will be released and land on Comet 67P/C-G. They have also released a much more readable summary of the most critical events, describing what will be happening.

For Americans, these events will be occurring from around 3 pm (Eastern) November 11, when the process begins, to 12 pm (Eastern) November 12, when Philae will send back the first signals after landing. Much of the most critical events will take place in the wee hours of the morning.

Meanwhile, one of Rosetta’s instruments has confirmed the presence of water vapor and carbon dioxide in the jets seen near the comet’s narrow neck.

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.
