The European Space Agency (ESA) is an intergovernmental organisation dedicated to the exploration of space, with 22 member states. Established in 1975 and headquartered in Paris, France, ESA has a staff of more than 2,000 with an annual budget of about €4.28 billion / US$5.51 billion (2013).
ESA's space flight programme includes human spaceflight, mainly through the participation in the International Space Station programme, the launch and operations of unmanned exploration missions to other planets and the Moon, Earth observation, science, telecommunication as well as maintaining a major spaceport, the Guiana Space Centre at Kourou, French Guiana, and designing launch vehicles. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching and further developing this launch vehicle.
Its facilities are distributed among the following 5 research centres:

Replay of Mr. Luigi Scatteia from PricewaterhouseCoopers, presenting the results of an ESA study to assess the socio-economic impact of the International Space Station (ISS), at the Space for inspiration event in London, UK, from 14-15 September 2016.
This video is part of a series of educational videos that ESA is releasing based on the five visionaries that lent their name to Europe’s space freighters. Jules Verne, Johannes Kepler, Edoardo Amaldi, Albert Einstein and Georges Lemaître form the inspiration to explain the principles of physics to young and older audiences. Presented by Anu Ojha, this video offers a good basis to introduce schoolchildren and the general public to the nature of cosmic rays and their effect on spacecraft and humans. Accompanying these videos are also a new set of resources that ESA education is producing: Teach with Space, a large set of demonstrations and teacher guides intended to bring the excitement of space into the classroom to inspire the next generation.

This virtual journey shows the different components that make up our home galaxy, the Milky Way, which contains about a hundred billion stars. It starts at the black hole at the centre of the Milky Way and with the stars that orbit around it, before zooming out through the central Galactic Bulge, which hosts about ten billion stars. The journey continues through a younger population of stars in the stellar disc, home to most of the Milky Way's stars, and which is embedded in a slightly larger gaseous disc. Stars in the disc are arranged in a spiral arm pattern and orbit the centre of the Galaxy. The discs and bulge are embedded in the stellar halo, a spherical structure that consists of a large number of globular clusters -- the oldest population of stars in the Galaxy -- as well as man...
A space mission to create the largest, most-accurate, map of the Milky Way in three dimensions will revolutionise our understanding of the galaxy and the universe beyond. On 19th December 2013, a rocket blasted into the sky from a launch site in French Guiana and travelled 1.5 million km to reach its destination in orbit around the Sun. The spacecraft is called Gaia. Its mission, funded by the European Space Agency and involving scientists from across Europe, is to make the largest, most precise, three-dimensional map of the Milky Way ever attempted. It will be a census of a billion stars spread across our galaxy. The results, says Professor Gerry Gilmore from Cambridge's Institute of Astronomy and the Principal Investigator for UK involvement in the mission, "will revolutionise our und...
Frank De Winne is answering a question on the ISS submitted by Paul from Portugal: When you do your EVA (space walk), can you feel the speed (28.000 Km/h) at which the ISS is travelling?
This animation tracks Rosetta's journey through the Solar System, using gravity slingshots from Earth and Mars to reach its final destination: Comet 67P/Churyumov--Gerasimenko. Rosetta made three flybys of Earth, on 4 March 2005, 13 November 2007 and 13 November 2009, and one of Mars, on 25 February 2007. Rosetta has also visited two asteroids, taking extensive close-up images of 2867 Steins on 5 September 2008 and 21 Lutetia on 10 July 2010. Once the spacecraft is woken up from deep space hibernation on 20 January 2014, it will head for rendezvous with the comet in May. In November the Philae probe will be deployed to the comet surface. Rosetta will follow the comet to its closest distance to the Sun on 13 August 2015 and as it moves back towards the outer Solar System. The nominal missio...
The European Space Agency has announced that astronaut Tim Peake--the first Briton to travel into space--will run the full London Marathon as it happens; to accomplish this task, he will be harnessed to a treadmill aboard the International Space Station. Running a marathon is an achievement in itself, but a British man has decided to make the experience even more challenging. The European Space Agency has announced that astronaut Tim Peake plans to run all 26.2 miles of the London Marathon during his International Space Station mission. Though he will begin the race at the same time as his fellow athletes on Earth, he will be running on a treadmill and wearing a harness to keep him from floating off. According to him, this system of straps on his shoulders and waist is his...

Satellites in airless space must endure high and low temperatures simultaneously, as some parts are exposed to sunlight and others remain in shadow. In advance of launch satellites are exposed to vacuum for prolonged periods, to ensure they can withstand extreme space conditions and maintain optimal internal temperature levels. Alessandro Cozzani, ESA’s Head of Engineering Services Section at the ESTEC Test Centre explains the advanced photogrammetry and thermal cameras which gather data during these challenging ‘thermal vacuum’ tests.

You, together with your 500 million fellow citizens from ESA's 20* European member nations, are the collective owners of one of the world's leading space agencies. The European Space Agency is an intergovernmental organisation, a cooperative coming together of its Member States in their national interest and common good. This new video offers a quick introduction: Europe, meet ESA. (*As of February 2015, 22 Member States)
Almost 50 years since man first walked on the lunar surface, the head of the European Space Agency explains his vision for living and working on the Moon. Johann-Dietrich Woerner believes the next giant leap for humankind could be an international collaboration of space faring nations in the form of a Moon village. This village would be a permanent lunar base for science, business, tourism or even mining. Woerner explains how using the Moon’s own natural resources could help build and sustain a base by 3D printing a structure or building element. Robotic rovers could inflate protective domes for astronauts. He also discusses the potential hazards of living on the Moon as well as the possible locations of he lunar base and the advantages of a new global space project.
Visualisation of the ExoMars Schiaparelli module entering and descending through the martian atmosphere to land on Mars. Schiaparelli will enter the atmosphere at about 21 000 km/h and in less than six minutes it will use a heatshield, a parachute and thrusters to slow its descent before touching down in the Meridiani Planum region close to the equator, absorbing the final contact with a crushable structure. The entire process will take less than six minutes: the animation has been sped up. Schiaparelli is set to separate from the Trace Gas Orbiter on 16 October, after a seven-month cruise together through space, and will enter the atmosphere on 19 October at 14:42 GMT. For an overview of the key timings and altitudes corresponding to the events portrayed in this animation see the Schi...
Gyroscopes form an important in keeping the International Space Station and satellites pointing the right way as they orbit our planet. ESA astronaut Tim Peake shows how gyroscopes can be used to keep spacecraft stable during his six-month Principia mission. There is no up or down in space. Satellites track their pointing direction using the same approach as on submarines and aircraft: fast-spinning gyroscopes that maintain a fixed orientation in the same way as a child’s spinning top. The International Space Station has four big gyroscopes which are used for stabilization of the Station.
