     8LISA Pathfinder will pave the way for a major ESA/NASA mission planned for the near future: LISA (Laser Interferometer Space Antenna), aimed at detecting gravitational waves generated by very massive objects such as black holes. Detecting gravitational waves will tell us more about the way space and time are interconnected.
     9The mission consists of placing two test-masses in a nearly perfect gravitational free-fall, and of controlling and measuring their motion with unprecedented accuracy. This is achieved through state-of-the-art technology comprising inertial sensors, a laser metrology system, a drag-free control system and an ultra-precise micro-propulsion system.

     11All these technologies are essential not only for LISA; they also lie at the heart of any future space-based test of Einstein's General Relativity. LISA Pathfinder is scheduled for launch at the end of 2009.
