This research programme is for participation in 3 experiments on space projects that test the predictions of General Relativity (GR) and test foundations of the theory. These are: 1. On GAIA: to determine the bending of light parameter, gamma (=1 in GR) to an accuracy of 1 part in 10^7, and to look for possible angular variations of gamma, which are not predicted by GR but could exist if the foundations of GR are incorrect. 2. Galileo-Galilei: To test the Equivalence Principle, that bodies fall together under gravity, which lies at the foundation of GR. This Italian mission, on which I am a co-investigator, should be able to detect possible violations at a level of 1 part in 10^17 3. CRONOS. Originally an ESA mission of opportunity to determine the gravitational redshift (the slowing down of clocks in a gravitational field) predicted by GR to 1 part in 1000,000 by comparing a high precision clock on board the Russian mission Radioastron with ground based clocks.

该研究计划旨在参与 3 个太空项目实验，测试广义相对论 (GR) 的预测并测试该理论的基础。它们是： 1. 在 GAIA 上：确定光参数的弯曲，伽玛（GR 中 = 1），精度为 10^7 分之一，并寻找伽玛可能的角度变化，这些变化不是 GR 预测的，但如果 GR 的基础不正确，则可能存在。 2. 伽利略-伽利略：测试等效原理，即物体在重力作用下落到一起，这是广义相对论的基础。我是这个意大利任务的联合调查员，应该能够检测到 10^17 中 1 部分的可能违规行为 3. CRONOS。最初是欧空局的一项机会任务，通过将俄罗斯无线电天文任务上的高精度时钟与地面时钟进行比较，确定 GR 预测的引力红移（引力场中时钟的减慢）为百万分之一。
