ESA PR 44-2015: LISA Pathfinder launch
LISA Pathfinder, ESA’s technology demonstrator for detecting gravitational-waves, is set for launch on 2 December at 04:15 GMT (05:15 CET) on a Vega rocket from Europe’s Spaceport in Kourou, French Guiana. Media representatives can follow the launch online and attend the event in ESA’s operations centre, ESOC, in Darmstadt, Germany. LISA Pathfinder will help to open up a completely new observational window into the gravitational Universe, by testing new technologies needed to measure gravitational waves in space. Predicted by Albert Einstein, these waves are ripples in the curvature of spacetime produced by massive celestial events, such as the merging of black holes. Detecting gravitational waves would also be an additional confirmation of General Relativity, and greatly enhance our knowledge of the most powerful phenomena in the Universe.

Launch event in Europe
Media are invited to join scientists, mission operators and engineers from the LISA Pathfinder team at a briefing in ESOC starting at 05:30 GMT (06:30 CET). The briefing will include the spacecraft’s separation from Vega, as well as the acquisition of the signal that confirms arrival in low orbit. Following a series of six orbit-raising manoeuvres within two weeks of launch, the spacecraft will journey for six weeks to its operating orbit around the Sun-Earth L1 Lagrange point, some 1.5 million km from Earth in a sunward direction.

About the European Space Agency
The European Space Agency (ESA) provides Europe’s gateway to space. ESA is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe’s space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world. ESA has 22 Member States: Austria, Belgium, the 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, of whom 20 are Member States of the EU. ESA has established formal cooperation with seven other Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement. 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. It is working in particular with the EU on implementing the Galileo and Copernicus programmes. ESA develops the launchers, spacecraft and ground facilities needed to keep Europe at the forefront of global space activities. Today, it develops and 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.
