ArianeGroup successfully tests solid rocket booster

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

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

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.
