Ariane 6, Corporate, Vega | June 20, 2017

After a very active first half in 2017, Arianespace signs its initial launch contract for the new Vega C launcher and gears up for Ariane 6

2017 Paris Air Show

Arianespace, which is sharing a chalet with ArianeGroup at this year's Paris Air Show, is focused on the future with the announcement of a first contract for the future Vega C launcher, while gearing up for the operation of Ariane 6. With an order book of 53 launches for Ariane 5, Soyuz and Vega, and fully engaged in marketing Ariane 6, Arianespace continues to prove its ability to satisfy current customers while addressing their future requirements.

Arianespace already has performed six launches this year between January 27 and June 1 – when the company celebrated the 79th successful Ariane 5 mission in a row while also setting a new record for payload injected into geostationary transfer orbit by this heavy launcher.

Arianespace announces the first Vega C contract and a new contract for Vega

Arianespace announced that it has signed the first contract for its Vega C launcher, to deploy Airbus' new generation of very-high-resolution optical Earth observation satellites. The contract provides for the launch of four satellites, using two Vega C launchers from the Guiana Space Center (CSG) in French Guiana, from mid-2020.

Arianespace also announced that it has signed a contract with OHB Italia SpA to launch an Earth observation satellite for the Italian space agency ASI, named PRISMA (PRecursore IperSpettrale della Missione Applicativa), to be orbited by a Vega rocket from the Guiana Space Center in 2018.
With these contracts, Vega and Vega C demonstrate they are perfectly compatible with the current and future launch markets for Earth observation satellites.

In addition to these contracts, Arianespace has signed two Ariane 5 launch contracts for geostationary satellites since the beginning of the year:
 

[/li]
• Horizon-3e, operated by SKY Perfect JSAT and Intelsat through a joint venture, with the launch planned as from the end of 2018,
• A high-throughput communications satellite for Eutelsat, with a launch scheduled in 2019. Along with this mission, Eutelsat also will allocate two satellites, Eutelsat 7C and Eutelsat Quantum, for launches in 2018 and 2019, respectively. Arianespace will therefore launch three satellites for Eutelsat during this two-year period.
  

Arianespace's order book now stands at 4.8 billion euros for 53 launches (18 by Ariane 5, 25 by Soyuz and 10 by Vega/Vega C) on behalf of 28 customers from around the world, clearly reaffirming its leadership in commercial space transport and its ability to meet all market expectations.

Records in performance, reliability and availability for the launcher family

Arianespace set a number of operational records in 2017:

[/li]
• Performance record
  

Arianespace marked a new performance record with the Ariane 5 launcher during its latest launch on June 1, 2017, boosting 10,865 kg into geostationary transfer orbit (GTO). This marks an increase of 1,500 kg. since the start of Ariane 5 ECA launches, and the capacity will continue to grow in the coming years.

[/li]
• Reliability record
  

Ariane 5 has carried out 79 successful launches in a row from the CSG, outpacing the record set by Ariane 4 in 2003 with 74 in a row. Vega has made nine launches, all successful, since entering service in 2012 at CSG, while Soyuz has logged a total of 43 missions from Baikonur and CSG.

[/li]
• Availability and flexibility record
  

The three launches delayed because of strikes in French Guiana were subsequently performed in less than a month, from May 4 to June 1, 2017. Arianespace's teams and partners stepped up to the plate during this situation, proving their flexibility and availability, while also reducing the length of launch campaigns by 25% in two years.

Arianespace also launched the first all-electric satellites this year, using Ariane 5 (Eutelsat 172B on June 1st) and Soyuz (SES-15 on May 18th), showing that its launchers are fully compatible with new-generation satellites using electric propulsion.

[/li]
• The 2017 objective: 12 launches
  

The next launch of Ariane 5 is planned for June 28, and will carry the two satellites Hellas-Sat 3-Inmarsat S EAN "condosat" for Inmarsat and Hellas Sat, and GSAT-17 for the Indian space agency ISRO (Indian Space Research Organization).  This will bring the total number of launches during the first half of the year to seven. Five more are planned in the second half, depending on payload availability: three by Ariane 5 and two by Vega.

6 successful launches in 4.5 months: January 27 – June 1, 2017 [/li] 8 injected into GTO by Ariane 5 and Soyuz, for a total launch weight of 34.5 metric tons. An Earth observation satellite launched by Vega. 6 more launches planned in 2017: 4 by Ariane 5 and 2 by Vega. 79 successes in a row for Ariane 5 Payload record into GTO of 10,865 kg by Ariane 5

2017 – 2023: Arianespace's priorities

Building on the first launch contract won by Vega C, Arianespace continues to gear up for the service entry of this upgraded light launcher, which will offer a larger fairing and higher performance.

The marketing of Ariane 6 has also started, including discussions with both government and private operators. Ariane 6 is a modular launcher, available in both the Ariane 62 and Ariane 64 versions, and fitted with a versatile upper stage featuring the new Vinci restartable engine and a new auxiliary power unit (APU), along with large payload capacity. These improvements will in turn enhance orbital injection and allow the launcher to handle an increasingly diversified range of missions, meeting the requirements for the promising mega-constellation market as well as seizing new opportunities with the advent of electric propulsion systems for satellites, while continuing to meet Europe's governmental needs.

At the same time, Arianespace continues to prepare for the operational transition between its current family of launchers and the new-generation Ariane 6 and Vega C, working alongside ArianeGroup, its majority shareholder and industrial prime contractor for Ariane launchers, as well as Avio/ELV, industrial prime contractor for Vega, and the European Space Agency (ESA). The Exploitation Review Key Point (ERKP) planned by ESA for the end of 2017, should finalize the different parameters for this transition phase. This should specify the commitment by European countries and institutions as customers for Ariane 6 and Vega C, thus guaranteeing sustainable and independent access to space for Europe, and also allowing these launchers to compete on a level playing field.

Finally, Arianespace pursuit with ESA the preparation of the LLL initiative (Light satellite-Low cost-Launch Initiative)), which was approved at the ESA Ministerial-level conference in December 2016, to provide low-cost launch services for small satellites on Ariane 6 and Vega C. This initiative clearly reflects Arianespace's determination to grasp all opportunities offered by the growth of the small satellite market.

At the opening of the 2017 Paris Air Show, Arianespace Chief Executive Officer Stéphane Israël said: "With 12 launches performed in 2016, 11 in 2016 and six between the beginning of 2017 and June 1, Arianespace has fully met our customer commitments since the last Paris Air Show in 2015. The performance, reliability and availability records set by, Ariane 5, Soyuz and Vega, once again demonstrate the outstanding launch service quality delivered by Arianespace to the benefit of its customers. With an order book now worth some 4.8 billion euros for 53 launches, we have reaffirmed our leadership in the commercial market, and are preparing for an unprecedented level of activity. By signing the first contract for Vega C and undertaking active preparations for Ariane 6, we are resolutely turning toward the next decade. We are very pleased to undertake these initiatives within the framework of ArianeGroup, in close partnership with Avio/ELV for Vega operations, and with the continued confidence of ESA, national space agencies in Europe and our shareholders – indispensable partners for the success of our future launchers."

Corporate, Vega | June 20, 2017

First launch contract for Vega C: Arianespace to orbit Airbus' upcoming constellation of observation satellites

Airbus Defence and Space and Arianespace today announced the signature of the launch services contract for the next generation of very-high-resolution optical observation satellites.

Two VEGA C launchers will orbit the four satellites in this constellation from the Guiana Space Center in French Guiana, as from mid-2020. By delivering images of each point on the globe several times a day, these extremely-agile optical satellites will keep a close watch on our constantly-changing planet.

Airbus Defence and Space is the first commercial customer for the upcoming VEGA C launcher. This enhanced version of the VEGA lightweight vehicle, which continues its brilliant career with nine successful launches out of nine, is now under development with a first flight slated for mid-2019.

Спойлер

Through this launch services contract, the higher-performance VEGA C version demonstrates that it provides a perfect launch solution for even the most advanced Earth observation satellites.

Above all, the contract reflects the continued confidence of Airbus Defence and Space, which was the first commercial customer for the original VEGA version in May 2013, with the launch of the VNREDSat-1 satellite for Vietnam. Since then, Airbus Defence and Space has chosen Arianespace for many other VEGA missions.

"We fully trust Arianespace to orbit our new constellation, which will bolster our service offering and expand our range of services," said François Lombard, head of the Intelligence Business Cluster at Airbus Defence and Space. "Along with a new-generation ground segment offering multi-mission and massive image processing capacity, our constellation will greatly expand access to higher-precision and more detailed images of Earth."

"Arianespace is extremely proud to have won this first launch contract for the upcoming VEGA C launcher from our long-standing customer and partner, Airbus Defence and Space," said Chief Executive Officer Stéphane Israël.

"We are highly honored by this expression of trust from Airbus Defence and Space. We also are delighted to kick off the VEGA C's commercial career with a contract reflecting Europe's continued leadership in very-high-resolution optical observation systems. This contract also is the latest mark of recognition of the quality and reliability of Arianespace's family of launchers. Our permanent commitment is our customer's satisfaction."

P120C, work in progress

The first Booster Case of the new P120C Solid Rocket Motor has recently completed manufacturing and successfully passed mechanical load and pressure testing at the Avio plant in Colleferro. Over the past few weeks, this first article has travelled to the European Spaceport in Kourou (French Guyana) where it is currently being prepared for inert propellant casting in Regulus (also a joint venture between Avio and the Ariane Group).

The P120C is the new first stage motor common to the new generation European launchers Ariane 6 and Vega C and it is jointly developed by Avio and the Ariane Group under their joint venture Europropulsion.  It is the largest monolithic carbon fiber solid rocket motor ever built, with solid propellant mass of 142 tons. The first article of this new motor will perform a static firing test in 2018, supporting the development schedule that will enable a first flight of Vega C by 2019 and Ariane 6 by 2020.

Ariane 6 and Vega C: concrete progress; staying on track

Technical innovations already introduced in current family

During 2017, Arianespace's current range of launchers has evolved to improve its competitiveness as from today.

Accordingly, both Ariane 5 and Vega are now being progressively fitted with new "out-of-autoclave" fairings, which will be systematically used on the new Ariane 6 and Vega C. Built by RUAG of Switzerland, these fairings are made by a simplified and more highly automated manufacturing process.

In parallel, Arianespace is continuing its Ariane 5 ECA performance improvement plan through the end of 2019, including increases in both payload weight carried and volume available under the fairing.

Finally, an overall competitiveness improvement plan will guarantee lower costs implemented on Ariane 5, even before the arrival of Ariane 6.

Gearing up for the operation of Ariane 6 and Vega C

After the French CNES space agency transferred its shares in Arianespace to Airbus Safran Launchers in December 2016, Arianespace's new governance structure took effect at the end of March 2017. Airbus Safran Launchers – which became ArianeGroup on July 1, 2017 – is now the majority shareholder in Arianespace, with 74% of its share capital. The rest of Arianespace's European shareholding remains unchanged.

Arianespace also is gearing up for the operation of Ariane 6 and Vega C, decided in conjunction with ESA, CNES in France, ArianeGroup and Avio. The partners are setting up a structure with greater integration of the different teams at the Guiana Space Center to boost competitiveness.

As a result, during the launch campaign for Vega's Flight VV10 mission – Avio, as industrial prime contractor for Vega – for the first time took responsibility for preparing the launcher until its liftoff (H0), while Arianespace maintains full responsibility for customer relations, as well as operations for the final countdown and the launch decision.

A similar change will be applied to Ariane 5 operations as soon as 2018.

Ariane 6 and Vega C: on schedule, with Arianespace customers at the heart of the process

The development of Ariane 6, with ArianeGroup as industrial prime contractor, is based on regular "Maturity Gates," with a first Ariane 6 launch planned for July 16, 2020, followed by a full capacity of 11 to 12 launches per year from 2023.

Arianespace is actively preparing the transition between its current launchers and Ariane 6 and Vega C. A key milestone on the operational and financial issues of the transition (2020-2023) will be held at the end of 2017 under the auspices of ESA. The conclusions will be presented to the ESA Council in March 2018. It is in this context that the European institutions will confirm their policy of grouped purchases of the Ariane 6 and Vega C launchers (with the first flight of Vega C scheduled for 2019).

Additionally, discussions are intensifying with commercial operators and institutional customers for the purchase of these future launchers – as already demonstrated by the first contract for Vega C and the first possible option for Ariane 6.

More than ever, Ariane 6 and Vega C are materializing – with the support of Arianespace customers – as Europe's response to the evolving space adventure, providing a source of new opportunities.

Сложно сказать, что учтено. Я лично так понял : 2080 кг - сухая масса корпуса двигателя; 3006 кг - сухая масса корпуса двигателя + сухая масса поворотного сопла с приводом + сухая масса переходного отсека между 1 и 2 ступенями.
