LISA Pathfinder

LISA Pathfinder (LPF), the second of the ESA Small Missions for Advanced Research in Technology, is a dedicated technology  demonstrator for the joint ESA/NASA Laser Interferometer Space Antenna (LISA) mission.

LISA Pathfinder was launched successfully on December 3, 2015, on a Vega rocket from Kourou. The LPF satellite is testing critical LISA technologies in a flight environment and is the first in-flight test of laser interferometry with a free-falling mirror, assessing the reliability of the associated micro-Newton thrusters, lasers, and optics. In order to analyse the incoming data from the experiment in near-real time and to be able to respond rapidly to the needs of the mission and the community involved, the François Arago Centre functions as the French data and analysis center, complementary to the ESA dedicated locations.
The centre provides the environment for the data exploitation during the mission, meeting facilities and a 24/7 access to data and analysis tools.
