![]() The LISA Pathfinder Mission Operations Centre (MOC) is located at ESOC, Darmstadt, Germany. + Preparing the technology to test gravitational-wave detection in space + Halo orbit about the Lagrangian point L1 (1.5 million km from Earth)ġ1 months may be extended up to 17 months Assessing the reliability of micro-Newton thrusters, lasers and optics in a space environment. ![]() Demonstrating laser interferometry with a free-falling mirror.Demonstrating that a test mass can be put in pure gravitational free-fall.LISA Pathfinder is testing certain technologies required for future LISA-like space missions that cannot be proven on Earth due to our planet's gravity, including: LISA Pathfinder’s initial operational phase will last 11 months and the mission could be extended by an additional 6 months. From there, it is using its own propulsion module to reach its final operational orbit, a 500 000 by 800 000-km halo orbit around the first Sun-Earth Lagrange point, at 1.5 million km from Earth. It was initially placed into a slightly elliptical parking orbit. ![]() LISA Pathfinder was launched on 3 December 2015 at 04:04 GMT (05:04 CET) onboard a Vega rocket from Kourou, French Guiana.
