Call for Media: LISA Pathfinder launch

Call for Media: LISA Pathfinder launch

23 November 2015

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.
