ABOUT ESA Space for Europe → the EUROPEAN SPACE AGENCY → ALL ABOUT ESA Space for Europe → THE EUROPEAN SPACE AGENCY From the beginnings of the ‘space age’, Europe has been actively involved in spaceflight. 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. Space is a key asset for Europe, providing essential information needed by decision-makers to respond to global challenges. Space provides indispensable technologies and services, and increases our understanding of our planet and the Universe. Since 1975, the European Space Agency (ESA) has been shaping the development of this space capability. By pooling the resources of over 20 Member States, ESA undertakes programmes and activities far beyond the scope of any single European country, developing the launchers, spacecraft and ground facilities needed to keep Europe at the forefront of global space activities. ← Cover: ESA astronaut Alexander Gerst during a spacewalk from the International Space Station in 2014 (NASA/ESA) CONTENTS → SPACE TO DISCOVER ......................................... 2 → SPACE FOR EARTH ............................................. 4 → SPACE TO LOCATE .............................................. 6 → SPACE TO COMMUNICATE ......................... 7 → SPACE TO INNOVATE .................................. 8 → ACCESS TO SPACE ....................................... 9 → SPACE FOR LIFE ........................................ 10 The Philae lander took a ‘selfie’of the Rosetta spacecraft at Comet 67P/Churyumov– Gerasimenko from a distance of about 16 km on 7 October 2014 (ESA/Rosetta/Philae/CIVA) science & robotic exploration → SPACE TO DISCOVER Over the past 40 years, Europe has marked a series of firsts in the exploration of the Solar System and of our Universe: from an encounter with Comet Halley in 1986, parachuting a probe on to Saturn’s moon Titan in 2005 and landing on a comet in 2014, to studying our Sun in unprecedented detail and photographing the farthest galaxies. To continue such successful achievements, ExoMars is a cooperation of ESA and ESA is now looking ahead to the next Roscosmos to continue the exploration of the 20 years with its Cosmic Vision programme.

This is one of intellectual and technological challenges the outstanding questions of our time, and a of tomorrow.

  • Ask Astronaut Alexander Anything
    Ask astronaut Alexander anything 11 March 2014 German European Space Agency (ESA) astronaut Alexander Gerst is all set for the 'Blue Dot' mission to the International Space Station in May. Crewmates NASA astronaut Reid Wiseman and commander-cosmonaut Maxim Surayev will hold a media conference on Tuesday 18 March 2014 and ESA is inviting you to ask questions via Twitter. Alexander is putting the finishing touches to his training before he heads to the Baikonur launch site in Kazakhstan in May. There, he will enter quarantine with his crewmates to make sure they do not bring any harmful viruses or bacteria to the orbital outpost. The trip to space is surprisingly short: within around six hours the Expedition 40/41 crew will dock with the microgravity laboratory orbiting 400 kilometres above Earth at 28,800 kilometres per hour. Once aboard, the new crew will have a week to get acclimatised to living without the benefit of gravity before their heavy workload begins. During their six months in space they will assist in the docking and unloading of six visiting spacecraft that ferry supplies and experiments. Alexander is prime operator for Europe's Automated Transfer Vehicle, meaning he will monitor the arrival and take responsibility for distributing the 2600 kilograms of items in its cargo bay. Alexander's science roster includes using the Electromagnetic Levitator for the first time. This furnace can melt and solidify metal alloys without a container, allowing scientists to understand the finer properties of these metals. Questions ESA is offering you the chance to ask the astronauts a question during the press conference via Twitter.

    Thales Alenia Space Experience on Plasma Propulsion IEPC-2007-301 Presented at the 30th International Electric Propulsion Conference, Florence, Italy September 17-20, 2007 Michel LYSZYK* and Laurent LECARDONNEL.† Thales Alenia Space, Cannes, 06150, France Abstract: Thales Alenia Space experience on plasma propulsion has been developed in the frame of Stentor, Astra 1K and GEI programs with plasma propulsion systems using SPT100 thrusters manufactured by Fakel and commercialized by Snecma . The PPS (plasma propulsion system) use in house equipments such as Power Processing Unit (PPU) manufactured by TAS-ETCA in Charleroi and the Thruster Orientation Mechanism (TOM) manufactured by TAS-France in Cannes . The PPS subsystem is used on board our SpaceBus satellite family to perform North-South station keeping. The on going activity on the XPS (Xenon Propulsion System) is devoted to the next European platform Alphabus currently under joint development by Thales Alenia Space and Astrium with CNES and ESA support. The XPS uses also the PPU manufactured by TAS-ETCA , the TOM manufactured by TAS-France and the Xe tank developed by TAS-Italy ; it use also the PPS1350 thruster under qualification by Snecma , a xenon regulator and a latch valve under development at Marotta Ireland.
