LISA Pathfinder prepares for final exams 18 June 2015 The summer is coming and that means students across Europe are sitting their final tests. ESA's LISA Pathfinder, a technology demonstrator that will pave the way for space-based gravitational wave observatories, is no different. It is currently in the test centre at IABG (Industrieanlagen-Betriebsgesellschaft), Ottobrunn, Germany. Read more
LISA Pathfinder will pave the way for future missions by testing in flight the very concept of gravitational wave detection: it will put two test masses in a near-perfect gravitational free-fall and control and measure their motion with unprecedented accuracy. LISA Pathfinder will use the latest technology to minimise the extra forces on the test masses, and to take measurements. The inertial sensors, the laser metrology system, the drag-free control system and an ultra-precise micro-propulsion system make this a highly unusual mission. LISA Pathfinder is an ESA mission, which will also carry a NASA payload.
