Abstract

A space experiment aimed at specifying the law of the Sun’s gravity more precisely is discussed. An extended “standard flight” scheme with two gravity assist maneuvers (slingshots) of a space probe near Venus and Earth is suggested, where the slingshots serve as amplifiers of small deflections caused by a deviation of the gravity law from a chosen ansatz. The deviation of the probe’s trajectory from its classic (Newtonian) pattern is calculated in detail using the isotropic Eddington–Robertson metric for the Sun’s gravity field and the “patched conic approximation” method for description of each slingshot. The trajectory deviation in the two-slingshots scheme is roughly assessed, the results indicating a principal possibility to detect the ultraweak distinctive feature of relativistic gravity.

两个弹弓可以探测到太阳引力的超弱特征
讨论了一项旨在更精确地确定太阳引力定律的空间实验。提出了一种扩展的“标准飞行”方案,在金星和地球附近的空间探测器中使用两个重力辅助机动(弹弓),其中弹弓作为由重力定律偏离所选轨道引起的小偏转的放大器。利用太阳重力场的各向同性爱丁顿-罗伯逊度量和描述每个弹弓的“补片圆锥近似”方法,详细计算了探测器轨迹与经典(牛顿)模式的偏差。对双弹弓方案的轨迹偏差进行了粗略的评估,结果表明有可能探测到相对论引力的超弱特征。

期刊介绍: Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoples’ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
