3 Arianespace Identity Card (1/3) Arianespace is a European company: Shareholders include CNES and 20 space companies representing 10 European countries Convention with the European Space Agency(ESA) Launches are performed at the Guiana Space Center(CSG) Three launch systems operating at CSG: The heavy-lift Ariane 5 The mid-size Soyuz(also launched from Baikonur with Starsem) The light-weight Vega For over 30 years, Arianespace has been the world reference in launching satellites for science, Earth monitoring, security and communications applications => The European Access to space 3

4 Arianespace Identity Card (2/3) Through Arianespace, Europe demonstrates its technical expertise based on the heritage of: 212 Ariane launches 30 Soyuzlaunches(4atCSGand26atBaikonurwithStarsem) 2 Vega launches Operating the launch vehicle family and relying on the benefits of Guiana Space Center(CSG), Arianespace offers: Services for European institutions Customized low-risk solutions for all customers From contract signature to in-orbit delivery, Arianespace provides turn-key service with the highest standard of customer care: Highly-skilled teams ensure efficient risks mitigation processes and smooth operations Flawless quality assurance with unique transparency Very accurate orbit insertion Value-added options for financing and insurance => A Premium Service 4

5 Arianespace Identity Card (3/3) A consistent and standard approach for the 3 Launch Vehicles: Improve quality and efficiency thanks to each other launchers cross experience Allow possibility of launch service back-up Simplify customer life Implementation of a unique approach for the whole family: Simplified industrial chain with a Prime Contractor for each Launch Vehicle, in development and in production Qualification Authority during the development phase involved as Independent Technical Authority during the production phase Payload Preparation Facilities (PPF) management, flight safety, security and launch base support under CNES responsibility => A Success-Proven organization which mitigate the risks Three launch systems, one unique approach 5

6 Arianespace at Guiana Space Center (1/4) European dedicated, state-of-the-art launch facilities Common facilities for the 3 Launch Systems Western standards, all required security levels Modern, efficient and operational facilities => Reduces program risks, increases operational flexibility 6

10 The French Legislative Framework (1/3) France adopted on June 3 rd 2008 the French Space Operations Act (FSOA). The general purpose is to set up a coherent national regime of authorization and control of space operations under the French jurisdiction. The FSOA and associated regulations are in force since December 10 th => The FSOA is directly applicable to Arianespace 10

11 The French Legislative Framework (2/3) Since December 2010, Arianespace is subject to FSOA framework and liability and is declared as Launch service operator. For each launch, Arianespace submit the necessary set of files which demonstrate the fulfillment of the technical regulation either in a generic or in a specific way. In particular: A generic demonstration of the conformity of the launch system at the state of the qualification. Description and domain of use Hazards study Environmental impact study Risks management plans A detailed description of the operator s organisation confirms the sustainability of the processes deployed and used by the operator in order to master the risks. A detailed description of the mission, including the dedicated specimen of launch vehicle and the spacecraft s characteristics. If any, additional specific risks mitigation measures would be detailed at this step. For each launch, the compliance to the FSOA and regulations must be demonstrated 11

12 The French Legislative Framework (3/3) With present launch systems, the qualified domain covers, in particular, the following risks mitigation measures: Clean separation systems for stages Orbital procedures designed to ensure accurate separation of entities and each other minimum distances Perigee constraints designed to minimise in-orbit dwell time Procedures for the passivation of stages remaining in orbit Controlled upper stage re-entry strategies where this is possible In addition, mission analyses studies detail: Trajectory optimization for minimization of hazard at fall down or reentry. Short range hazard mitigation through trajectory corridors, ground and altitude wind limitations. Long range Atlantic Ocean drop zones determination and constraints. Long range cumulative risk minimization within legal criteria thresholds. Inhabited orbiting object collision risk avoidance measures Planetary protection measures where this risk exists => Arianespace applies risks mitigation measures 12

21 Conclusion For Arianespace: Safety is not an option Arianespace positioning on the global market is based on: A stable shareholding structure; Over 30 years of experience launching satellites for operators and agencies from all around the world; An experienced world class operational team and a state of the art launch base; A robust capacity in monitoring launchers quality for the highest reliability; The application, on ground and in flight, of risks mitigation measures induced by return on experience and legal framework. These practices contribute to preserve an operational culture of safety and reliability in our activities 21
