ISLAND(平方反比定律和牛顿动力学)空间探测器是一个新概念,用于在以下两个尺度上测试引力平方反比定律:(1)亚毫米尺度;(2)最大太阳系尺度(几十个天文单位-Au)。主要的想法是在一个专用的,可能是无阻力和姿态控制的行星际探测器的重心上安装一个扭摆,该探测器的重力环境由六个超灵敏的加速度计精确探测并校正,这些加速度计在扭摆周围布置成十字形。
The ISLAND (Inverse Square Law And Newtonian Dynamics) Space Explorer is a new concept to test the gravitational Inverse Square Law at: (1) submillimeter scale and (2) at the largest Solar System scales (dozens of Astronomical Units --AU). The main idea is to embark a torsion pendulum at the center of gravity of a dedicated, possibly drag-free and attitude-controlled, interplanetary probe whose gravitational environment is accurately probed by, and corrected for thanks to six ultrasensitive accelerometers arranged as a cross around the torsion pendulum.
