LISA探路者(前身为SMART-2)是欧空局的一项任务，旨在通过在飞行中测试空间引力波探测所需的关键技术，为欧空局/美国国家航空航天局激光干涉仪空间天线(LISA)任务铺平道路；它将把两个测试质量置于近乎完美的引力自由落体状态，并以前所未有的精度控制和测量它们的运动。这是通过包括惯性传感器、高精度激光计量、无阻力控制和超精密微牛顿推进系统的技术实现的。LISA探路者任务目前处于C/D阶段--实施阶段，定于2010年启动，之后6个月内将得出系统性能的结果。
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 an unprecedented accuracy. This is achieved through technology comprising inertial sensors, high-precision laser metrology, drag-free control and an ultra-precise micro-Newton propulsion system. The LISA Pathfinder mission is now in Phase C/D - the Implementation Phase, and is due to be launched in 2010, with results on the performance of the system being available within 6 months thereafter.
