ЦитатаEurope looks to lighter, more nimble launcher after 2020
BY STEPHEN CLARK
SPACEFLIGHT NOW
Posted: October 16, 2009

The replacement for the Ariane 5 rocket after 2020 will likely be smaller and less expensive to meet the needs of lighter European Space Agency missions, according to the head of the agency's launcher program.

"The fact that we want launchers that serve our institutional missions means that we need a smaller launcher than Ariane 5, it being understood that Ariane 5 could serve the space station with ATV and launch exploration missions," said Antonio Fabrizi, ESA's director of launchers.

The Ariane 5's most powerful version can lift more than 21,000 pounds to geosynchronous transfer orbit and more than 44,000 pounds to low Earth orbit.

There are few individual ESA or commercial payloads capable of filling the Ariane 5's capacity, so Arianespace launches pairs of communications satellites on most of its flights.

One exception is the Automated Transfer Vehicle, a major ESA contribution to the International Space Station. The ATV weighs more than 42,000 pounds at launch, nearly maxing out the Ariane 5's capabilities.

The first ATV, named Jules Verne, delivered supplies to the station last year. At least four more ATV's are scheduled to fly through 2015.

But officials do not foresee many other payloads taking advantage of the Ariane 5's heavy-lifting capacity, unless ESA launches more ATV's, develops a human space transportation system, or takes a significant role in deep space exploration, Fabrizi said.

Ariane 5's prognosis may largely depend on policy decisions in the United States, especially on exploration and human spaceflight topics now being reviewed by leaders at NASA and in the White House.

ESA and NASA have been trending toward closer cooperation than ever before in recent months, including agreements on a combined Mars program, space transportation and discussions of an Earth sciences partnership.

"I'm not saying that Ariane 5 may be out of scope for us at all. On the contrary, but we have to think of what is best for us in the long term," Fabrizi said.

The outlook for ESA institutional missions, mostly science payloads, will determine the size of the Next-Generation Launcher, as the program is officially named.

"We look particularly at what we need for our institutional missions. Ariane 5 is not the most-used by us, so we would like a launcher that is better suited for the European institutional missions," Fabrizi said.

The commercial viability of a rocket is a secondary concern.

Jean-Yves Le Gall, chairman and CEO of Arianespace, declined to comment in detail on the Ariane 5's long-term future in an interview with Spaceflight Now.

"Today it is just a preliminary thought and I do not want to comment more than this because there is a very big spectrum of ideas," Le Gall said.

ESA is studying configuration options and consulting the agency's member states before potentially deciding on requirements for the new rocket.

The Ministerial Council, consisting of representatives of ESA member nations, gave support to the agency's Future Launch Preparatory Program during a meeting last November.

Officials are now soliciting input and ideas from the ESA's 18 member states, specifically France, Germany and Italy, according to Fabrizi.

"Looking at the scenarios after 2020 or 2025, we have to think what the demand for launchers will be. We have a roadmap that should lead to to the next Ministerial (Council) in the coming years," Fabrizi said.

"This roadmap starts with the delegations of our member states to discuss different scenarios and different requirements and what is the mission we want to give this new family of launchers," Fabrizi said.

ESA has also signed contracts for a high-thrust engine demonstrator that could be used on the new rocket.

The alternatives under review include configurations with solid and liquid propulsion, various numbers of stages and strap-on boosters.

"We have tradeoffs ongoing on different types of propulsion and staging. I think if we look at the long term evolution of the ESA family of launchers, we may think of Vega 2 and Ariane 6. But these are just names," Fabrizi said.

Prospects for a reusable launcher have been shelved due to concerns with technology development and high costs. ESA still plans to launch a small reusable re-entry demonstrator in 2012, and most of that mission is already funded.

In the meantime, officials are studying plans to install a more powerful and more reliable upper stage on the Ariane 5 by about 2016.

The upgrade would include the Vinci engine, a brand new power plant that would replace the Ariane 4 heritage HM-7B engine used on the Ariane 5's ECA upper stage.

The Vinci could allow the Ariane 5 to deliver cargo directly into geosynchronous orbit, cutting the amount of fuel satellites have to carry.

Officials expect decisions on both the evolution of Ariane 5 and a future replacement in 2011.

French bond issue to back Ariane 6, new satellites
ЦитатаFrench President Nicolas Sarkozy has unveiled a plan for a multibillion euro bond issue that will benefit a range of French and European aeronautics and space projects.            
The issue, set for next year, calls for spending 35 billion euros ($52.5 billion) on high-tech projects to help the country recover from the effects of the global economic crisis. Although the bulk of funding will go to universities and basic research and to promote sustainable development, 6.5 billion euros will be earmarked for high-impact industrial initiatives .Chief among the space projects destined to benefit are a new launcher to replace the Ariane 5 heavy-lift rocket and new satellite designs, including a spacecraft constellation to monitor carbon dioxide emissions.

ESA Begins Work On Ariane 6
ЦитатаPARIS -- European Space Agency (ESA) head Jean-Jacques Dordain says the agency does not plan any program rollbacks due to cash flow problems that are afflicting the agency, and will move aggressively to define a concept for a new heavy-lift launch vehicle that would succeed the Ariane 5.

Dordain says ESA spending has grown an average of 10 percent per year since 2006 as the agency has ramped up new programs approved at the 2005 and 2008 ministerial summits. The sum reached €3.35 billion ($4.8 billion) last year. Although this was well below the 2009 budget, fiscal shortfalls in a number of ESA member countries provoked by the ongoing financial crisis created a cash crunch, forcing the agency to borrow money to pay near-term payment obligations.

To resolve the cash flow matter, ESA will freeze spending at 2009 levels (except for Galileo FOC) through 2010 and 2011, Dordain says. In addition, the agency will attempt to negotiate new contracts with lower payments at contract signature and higher payments on delivery. Anticipated slippage in existing programs also is expected to help.
...
The new heavy-lift launch vehicle would replace the Ariane 5 around 2025. The European launch community says the changing market calls for a new vehicle sized more closely to fit government requirements and designed so that commercial launch needs are not central to its sustainability. The objective, Dordain says, is to arrive at the next ministerial summit in 2011 with a firm definition proposal for the new booster, known in ESA parlance as the New Generation Launcher (NGL) but commonly called the Ariane 6.

The undertaking received a major boost in December when it was named to benefit from a special French government bond issue. Valerie Pecresse, the minister in charge of space, says the bond issue will provide €250 million ($360 million) to begin definition of the Ariane 6, which is expected to cost €3.5 billion to €8 billion to develop.

Dordain says ESA has already begun studying Ariane 6 concepts with French space agency CNES and other member states using building blocks and funding provided through the Future Launcher Preparatory Program (FLPP). Dordain notes that many of the design choices remain to be made, including which type of propulsion system -- cryogenic, storable propellant or advanced solid rocket -- should be used. However, he says the new vehicle will almost certainly adopt the modular approach that French engineers have proposed, capable of launching three to six or seven metric tons -- the upper limit of telecom satellites -- to geostationary transfer orbit. This would shift the focus from dual launches, which have long been the hallmark of Arianespace, to the single launch approach followed by competing operators.

Antonio Fabrizi, the ESA launcher director, says the other member states involved in launcher activity, notably Germany and Italy, are in basic agreement with the French approach. Fabrizi notes that the French concept is itself a refinement of a 4-8 metric ton modular configuration already being studied in FLPP. "But France is providing the impetus to move forward," he says. "Every program needs a political push."
