Chinese Academy of Sciences to detect gravitational waves, "Tai Chi program" announced "roadmap"
News Agency in Beijing, June 3 (Xinhua Zhang Su), Chinese Academy of Sciences on space gravitational wave detection, "Tai Chi program" roadmap: 2016-2020 research and key technology breakthrough key technologies application and verify 2020-2025; 2025-2033 for testing and launching.
Chinese Academy of Sciences, "Tai Chi program" Wu yueliang 3rd, Chief Scientist at the Chinese Academy of Sciences Fellow, Division of the fifth annual plenary Symposium for disclosing the news.
On February 11, 2016, United States researchers announced by the Laser Interferometer Gravitational-wave Observatory (LIGO) gravitational waves has been observed for the first time, found it was not only a direct verification of the predictions made by Einstein's theory of general relativity, a more in-depth study on the nature of gravity, space and time structure and evolution of the universe to provide an experimental Foundation.
Chinese Academy of Sciences space gravitational wave detection working group has launched "the Tai Chi program"-equilateral triangle to launch 3 satellites detect star group, Earth-Sun direction about 18-20 degrees in orbit around the Sun. Said Wu yueliang, 3 satellites that form the plane with about a 60-degree angle between the ecliptic, maintain the stability of thermal radiation.
Wu yueliang added said, 2016-2020 of task including general planning and programme optimization,, also will using gravity wave detection technology carried out time-varying Earth gravity satellite flight model Foundation Research; 2020-2025, will launches next generation time-varying Earth gravity satellite, carried out Earth and marine science and the global environment changes of research, and development "Tai Chi plans" experiment prototype; 2025-2033, in Foundation research based Shang development engineering prototype, then for related test, Reach the Foundation of all indicators, launching satellites, carried out experiments.
According to reports, the "Tai Chi program" will mainly detect low frequency gravitational waves, focusing on exploring how the seeds of intermediate-mass black hole formation, dark matter can form seed black holes, seeds and how black holes grow into massive black holes, black holes merge and other cutting-edge issues that reveal the nature of gravity.

中科院探测引力波“太极计划”公布“路线图”
中新社北京6月3日电(记者 张素)中国科学院关于空间引力波探测的“太极计划”有了路线图：2016—2020年进行预研和关键技术突破；2020—2025年进行关键技术应用和验证；2025—2033年进行测试和发射。
中国科学院院士、“太极计划”首席科学家吴岳良3日在中国科学院学部第五届学术年会全体院士学术报告会上披露了这一消息。
2016年2月11日，美国科研人员宣布利用激光干涉引力波天文台(LIGO)首次观测到引力波，其发现不仅是对爱因斯坦广义相对论所做预言的一次直接验证，更为深入研究引力本质、时空结构和宇宙演化提供了实验基础。
中科院空间引力波探测工作组也发起了“太极计划”——发射3颗卫星组成等边三角形探测星组，在位于偏离地球—太阳方向约18—20度的位置进行绕日运行。吴岳良说，3颗卫星所构成的平面与黄道面之间约成60度夹角，保持热辐射的稳定性。
吴岳良补充说，2016—2020年的任务包括总体规划和方案优化等，还将利用引力波探测技术开展时变地球重力卫星飞行模型地基研究；2020—2025年，将发射下一代时变地球重力卫星，开展地球和海洋科学及全球环境变化的研究，并研发“太极计划”实验样机；2025—2033年，在地基研究基础上发展工程样机，然后进行相关测试，在达到地基研究各项指标后，发射探测卫星、开展实验。
据介绍，“太极计划”将主要探测中低频段引力波，重点探索中等质量的种子黑洞如何形成、暗物质能否形成种子黑洞、种子黑洞又如何成长为大质量黑洞、黑洞合并过程等前沿问题，揭示引力本质。(完)
