标题： The Laser Astrometric Test of Relativity: Science, Technology, and Mission Design

摘要： 激光天体测量相对论实验（LATOR）旨在探索太阳附近的广义相对论——太阳系中最强的引力环境。 利用高精度测量的独立时间序列，包括Shapiro时间延迟（星际激光测距在2天文单位处精确到3毫米）和干涉天体测量（精确到0.01皮弧度），LATOR将以前所未有的精度（10亿分之一）测量光在太阳引力作用下的偏折——其精度比目前可用的水平提高了约30,000倍。 LATOR将在其寻找太阳系中标量场宇宙遗迹的过程中进行一系列高精度测试。 我们介绍了LATOR任务的科学、技术和任务设计。 显示英文摘要

摘要： The Laser Astrometric Test of Relativity (LATOR) experiment is designed to explore general theory of relativity in the close proximity to the Sun -- the most intense gravitational environment in the solar system. Using independent time-series of highly accurate measurements of the Shapiro time-delay (interplanetary laser ranging accurate to 3 mm at 2 AU) and interferometric astrometry (accurate to 0.01 picoradian), LATOR will measure gravitational deflection of light by the solar gravity with accuracy of 1 part in a billion -- a factor ~30,000 better than currently available. LATOR will perform series of highly-accurate tests in its search for cosmological remnants of scalar field in the solar system. We present science, technology and mission design for the LATOR mission.
