摘要
天琴是一个规划中的天基引力波(GW)天文台，由三颗地球轨道卫星组成，轨道半径约为 。卫星将构成一个等边三角形星座，其平面几乎垂直于黄道面。天琴旨在探测 至 之间的引力波，这些引力波可由多种重要的天体物理与宇宙学源产生，包括银河系超紧凑双星的旋进、恒星级黑洞双星旋进、极端质量比旋进、大质量黑洞双星并合，以及可能的极早期宇宙中的高能过程或宇宙弦等奇异源。为在 2035 年前后开展科学观测，正采用称为 0123 计划的路线图使天琴关键技术成熟化，并得到一系列地面研究设施建设的支持。0123 计划的两个重大项目正在实施。在此过程中，团队研制了新一代 单体空心角锥棱镜 retro-reflector，已于 2018 年 5 月 21 日随鹊桥卫星发射；建成了配备 望远镜的新激光测距站，并已成功测距到月球上全部五个 retro-reflector；天琴一号试验卫星于 2019 年 12 月 20 日发射，首轮结果表明卫星已超出全部任务指标要求。
