LISA Pathfinder (formerly known as SMART-2) is an ESA mission designed to pave the way for the joint ESA/NASA Laser Interferometer Space Antenna (LISA) mission by testing in flight the critical technologies required for space-borne 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 carry two technology payloads, the European provided LISA Technology Package (LTP), and the NASA provided Disturbance Reduction System (DRS). The LTP comprises two inertial sensors, high precision laser metrology, drag-free control and an ultra-precise micro-Newton propulsion system. The DRS consists of a drag-free control system and a micro-Newton propulsion system. The DRS will use the LTP inertial sensors.
LISA Pathfinder is due to be launched in late 2009, with first results on the performance of the system being available approx 6 months later.
This poster gives an introduction to, and status of, the mission, followed by more details on the technologies to be tested in a space environment. It will also highlight the ways in which the LISA Pathfinder mission will be used for the preparation of LISA, e.g. ground segment development, on-orbit commissioning of the hardware, etc. as well as technology development.
