天琴计划预期于2035年左右发射并部署边长约17万公里的等边三角形卫星星座,构成一个引力波天文台—天琴。天琴将对10-4～1 Hz频段的引力波进行探测,为人类描绘一幅更全面的宇宙图景。在本文中,我们对天琴计划的背景和提出过程、天琴的主要探测对象和主要科学目标、天琴需要攻克的核心关键技术问题、天琴计划技术路线图及进展等进行介绍,以方便更多人加入这一项富有挑战而又激动人心的工作。

：The TianQin project aims to launch and deploy around 2035 an equilateral triangular constel⁃ lation with each side measuring 170 000 kilometers，forming a gravitational wave observatory：TianQin. TianQin aims to detect gravitational waves in the frequency range 10-4 ~1 Hz and to draw a more compre⁃ hensive picture of the universe for mankind. In this article，we introduce the background and the propos⁃ ing process，the major gravitational wave sources and scientific objectives，the key technology problems to be solved，the technology roadmap，and the current progress of the TianQin project，so as to facilitate more people to join in this challenging and exciting work.
