Testing LISA technology in space

LISA Pathfinder is a technology demonstration mission for  LISA (Laser Interferometer Space Antenna) consisting of two LISA-like test masses in a single satellite. As in LISA, these test masses will be kept drag-free and an interferometer will monitor their position fluctuations with picometer precision. In this sense, LISA Pathfinder can be regarded as a single LISA arm scaled down to 30 cm and enclosed in one satellite. Its implementation phase has already begun and launch is presently scheduled for 2010.

LISA Pathfinder will carry two different payloads: the European LISA Technology Package (LTP) and the NASA-provided Disturbance Reduction System (DRS). The investigations at the Albert-Einstein-Institute regarding LISA Pathfinder focus on the LTP interferometry.
