Ariane 6 (artist's concept)
- European nations announced last Tuesday they would build a new generation rocket in a multi-billion-euro programme to maintain their grip on the world market for satellite launches.
- European Space Agency (ESA) ministers "took a major decision to develop a new launcher, the Ariane 6, which will replace the Ariane 5, with a maiden flight scheduled for 2020," French Research Minister Genevieve Fioraso said in a statement describing the deal as "historic."
- Tuesday's agreement came after months of behind-the-scenes haggling to ease a rift between France and Germany over Ariane 5's successor.
- "This is a very important day for the space agency after sometimes very tough but very fair and open discussions," said Luxembourg Economy and Trade Minister Etienne Schneider.
- "It's a success, I even dare to call it a big success," said Jean-Jacques Dordain, ESA's director-general, explaining that nations had pledged nearly 6 billion € (nearly $7.5 billion) for operations in the coming years.
- He praised member states for making "an exceptional effort... because we know that the economic situation is difficult."
- Four billion euros have been earmarked for Ariane 6, of which 400 million euros will come from industry, officials said. A review of progress will be made in 2016.
- Over 10 years, the 20-nation alliance will spend about eight billion euros on its launcher programme, including infrastructure such as a new launch pad at its base in Kourou, French Guiana.
- The Ariane 5 traces its roots back nearly three decades. A medium-to-heavy workhorse with an unbroken string of more than 60 successful launches to its name, it accounts for more than half of the world's commercial launch market.
- Despite its reliability, Ariane 5 comes with high operational costs compared to nimble US commercial newcomers such as SpaceX.
- "With this historic decision, the member states have given a strong reply to international competition in a strategic sector for European sovereignty, industry and jobs," Fioraso said.
- "They showed that when it is united, Europe is strong and can respond collectively to challenge."
- A replacement for the Ariane 5 had been a source of friction for the last two years, with France and Germany - ESA's two biggest contributors - pushing alternative approaches.
- Germany said a new rocket would take so long to develop that rivals would have grabbed a fat share of the satellite market by the time it was ready.
- It argued for a modified version of the existing rocket - the Ariane 5 ME, for Midlife Evolution - which would be ready by 2017 and yield early operational savings.
- France had lobbied for switching directly to Ariane 6, whose first flight would take place in 2021 or 2022.
- It argued the ME would drain crucial resources and lead to duplicated effort and probable holdups.
- Under a compromise, the Ariane 6 will incorporate existing designs from the Ariane 5, ME and other projects.
- It will culminate in two versions - a two-booster or four-booster design - able to take between five and 10 tonnes into orbit.
- It will include a solid rocket motor, the P120C, being designed as an upgrade for ESA's Vega launcher that should be operational from 2018, as well as a strap-on booster.
- But much of the rest will come from the Ariane 5, thus saving development costs and time, according to engineers.
- According to Stephan Israel, head of Arianespace, which markets ESA's services, the current market price for a single launch of two satellites "is around $120 million."
- The public face of the wrangle was about different approaches in engineering, driven by arguments of cost overruns and delay.
- But an undercurrent was about sharing the funding bounty within Europe's space industry. France and Germany together account for nearly half of ESA's financing for launchers.
- In return for climbing down on the ME, Germany lobbied France and Italy to beef up contributions to the International Space Station (ISS), where German firms have a big stake.
- ESA had sought a three-year, 820-million-euro budget for the manned outpost in space.
- "We have a figure of 800 million €, it is more or less what we have requested," said Dordain.

Answers:
3) List the positive aspects of
Ariane 5 (use the information in the text, your own knowledge/opinion, and
information you can find on the Web).
A medium-to-heavy workhorse with an unbroken string of more than 60
successful launches to its name, it accounts for more than half of the world's commercial
launch market.
4) Why is the ESA wanting to build a
new satellite launcher?
Despite its reliability, Ariane 5 comes with high operational costs. The Ariane 6 is being built as “a strong reply to international
competition in a strategic sector for European sovereignty, industry and jobs.”
5) What difficulties has the Ariane 6
programme faced?
Difficulties over who decides, design, cost, subsidies, and commercial
considerations. The French want a new design, the Germans want to modernize the
Ariane 5 so as to stay in the competition. A compromise has been found over the
design and the amount of subsidies has been decided on, which shows that “when
it is united, Europe is strong and can respond collectively to challenge."
6) Why is the ESA weary of the SpaceX
programme?
SpaceX, one of the US newcomers in the sector, produces more “nimble”
rockets: smaller, lighter and cheaper. This means that the ESA is afraid that
clients will buy the SpaceX rocket rather than the Ariane 6. The ESA seems to
rely on the good reputation of the Ariane 5 to promote, once built, its Ariane
6 (should it not take more seriously the idea of cheaper and lighter rockets?).

How can the EU, from my point of view, maintain its lead in the satellite launch service industry?
The development of the satellite industry involves the research and development and construction of new satellites, the design and construction of new launch rockets, and the modernization of launch facilities.
I think firms like SpaceX and the “agile aerospace” ideas of the small team of idealistic experts at the Planet Labs garage are the future of the satellite industry: building nimble rockets for light but highly sophisticated satellite payloads. The launch service industry has to adapt to this inevitable evolution…
Compared to big satellites, smaller satellites (like the Dove satellites) are cheaper to build and the launch rockets for them do not need to be big. That means that the launch rockets are cheaper to produce (and less damaging to the environment!) and need less extensive launch facilities. That makes the firms producing the satellites and the rockets highly competitive.
The Ariane 6 project on the other hand is a white elephant, a project to produce a heavy rocket for medium to heavy payloads. It is not innovative. Its development and eventual construction rely on huge public subsidies, slow international cooperation, numerous teams of experts, engineers, specialist workers and even the army, plus extensive launch facilities, all of which makes it commercially uncompetitive.
I think Europe cannot maintain its lead in the satellite launch service industry, unless there is a paradigm shift in how we conceive and use and construct satellites and launchers, and in the way the industry is organized as a consequence. The stakes - employment, political influence, European cooperation - are too high for there to be any real innovation and change in the way the industry is organized in the EU; no politician or industry boss will have the courage to make the inevitable decisions…
