LISA Pathfinder’s name (Laser Interferometry Space Antenna) clearly indicates the role of precursor that this mission plays. Its goal is for preparing the technology to test gravitational-wave detection in space. This will open new doors for our understanding of the universe. LISA Pathfinder will be launched before the end of the year on a Vega from Kourou in French Guiana. This video shows LISA Pathfinder in preparation near Munich in Germany.
