The European Space Agency (ESA)

The European Space Agency (ESA) is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.

Formed in 1973, when a Ministerial Conference in the Hague approved a highly ambitious space programme to carry the European space effort into the new millennium.

Since the last ESMATS, Ariane 5 successfully completed its 100th launch and has an order book stretching into 2022. BepiColombo, Metop-C, EDRS_C, CHEOPS and Solar Orbitor have all been successfully launched. XMM-Newton has successfully completed 20 years in orbit and continues to provide ground breaking science; its sister spacecraft INTEGRAL, launched in October 2002 is also still operational and SOHO launched in December 1995 has completed  25 years of successful sun observation and comet spotting. The Cluster II satellites launched in the summer of 2000 are also still operational after 20 years in orbit.



ESA member states

ESA has 22 Member States; Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, The Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. Further to the 22 Member States, Canada and Slovenia, based on their agreements with ESA, also qualify to fully participate in the programmes of the ESA Education Office. Seven other EU states have Cooperation Agreements with ESA: Bulgaria, Croatia, Cyprus, Latvia, Lithuania, Malta and Slovakia.
By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country.

ESA develops the launchers, spacecraft and ground facilities needed to keep Europe at the forefront of global space activities.

Today, it launches satellites for Earth observation, navigation, telecommunications and astronomy, sends probes to the far reaches of the Solar System and cooperates in the human exploration of space.

ESA’s purpose shall be to provide for, and to promote, for exclusively peaceful purposes, cooperation among European States in space research and technology and their space applications, with a view to their being used for scientific purposes and for operational space applications systems:

  • by elaborating and implementing a long-term European space policy, by recommending space objectives to the Member States, and by concerting the policies of the Member States with respect to other national and international organisations and institutions;
  • by elaborating and implementing activities and programmes in the space field;
  • by coordinating the European space programme and national programmes, and by integrating the latter progressively and as completely as possible into the European space programme, in particular as regards the development of applications satellites;
  • by elaborating and implementing the industrial policy appropriate to its programme and by recommending a coherent industrial policy to the Member States.

RUAG Space is the leading supplier of products for the space industry in Europe, and with a growing presence in the United States. Experience, outstanding reliability, customer focus and a comprehensive, clearly structured product portfolio all make RUAG Space the partner of choice for manufacturers of satellites and launchers across the globe.

RUAG Space keeps things moving on board of satellites
Mechanism engineering and production is covered by three of RUAG Space’s thirteen sites: mainly by the one in Zurich, Switzerland – the headquarters of the company – but also by the sites in Vienna, Austria and Coswig in Germany.

RUAG Space is one of the major space mechanism suppliers worldwide. The products are particularly sought after for precise positioning and motion control within payload instrument mechatronics, solar generators, thrusters and antennas.

RUAG Space is the top ranked supplier of Solar Array Drive Assemblies (SADA) worldwide, with in-house capabilities to provide clients with turn-key solutions consisting of mechanism and associated drive and control electronics.

The company is specialized particularly in the field of pointing, deployment, high performance separation, payload mechanisms and robotics, qualifying as the only European supplier offering a full range of SADM (Solar Array Drive Mechanism) worldwide from the micro satellite class up to the largest telecom and Earth observation satellites.

RUAG Space Rotary Actuators are used for antenna deployment and pointing, solar array deployment and electric propulsion pointing. For deployments and separation, RUAG offers a broad range of mechanisms with a long history of success. For instance, RUAG Space developed the separation mechanism for the Cassini/Huygens mission as well as for ESA’s ExoMars mission. For ExoMars, RUAG also performed the testing of the Rover’s locomotion system, at Switzerland’s largest tiltable sandbox, perfectly simulating Martian surface characteristics.
RUAG Space offers pointing and positioning mechanisms and subsystems as well as mechanisms for electric propulsion pointing, which are increasingly used on commercial satellite platforms and scientific spacecraft due to their advantages in fuel mass efficiency. Next to products and subsystems, RUAG has a wide portfolio of building blocks such as rotary actuators, motors, dampers and hold-down-and-release mechanisms.

RUAG mechanisms on many missions
The primary deployment mechanism of the solar array for the Hubble Space Telescope, the SADA for the BepiColombo, the electrical propulsion pointing mechanism for SMART-1 and Artemis, the scan mechanism for the IASI Instrument and SADM on the MetOp satellites are examples of RUAG’s mechanism expertise. Also, NASA’s Orion MPCV mission will use RUAG mechanisms. The 2-Axis SADM for the wings of the European Service Module are developed, manufactured and tested in Zurich.

Beyond mechanisms: electronics and structures
RUAG Space’s portfolio further includes electronics and structures for both satellites and launch vehicles. For instance, RUAG Space supplies radiation-hard and fault-tolerant computers to ensure that rockets arrive in space safely and that the various systems on board satellites work together seamlessly, year after year. RUAG counts deliveries to the Ariane program in the hundreds. The company’s data handling systems and control computers for diverse satellite applications are trusted by numerous commercial and scientific missions.

RUAG Space products are chosen by all leading launch service providers. The company has equipped every Ariane rocket with payload fairings since the very first launch in 1979, and its composite structures feature on board the American Atlas rockets. Stage adapters from RUAG connect first and upper stage, or upper stage and spacecraft – with contribution to the American Space Launch System as the most recent mandate.
