AstroSat, a dedicated Space Observatory of India, has completed five successful years of operation in space on 28th September 2020. AstroSat is a quite complex satellite, as it is a multi-wavelength observatory with many scientific instruments. The saga of many agencies, including Indian Space Research Organisation, the lead agency, and many scientists and engineers has resulted in realizing and operating this mission with excellent performance and highly satisfactory results. This mission generated a lot of observations leading to enhanced research activity for Indian astronomers, as well as international astronomers. It has also kindled interest, as expected, in young scientists and science students. The mission still continues in orbit contributing to celestial observations. AstroSat is a collaborative effort of many agencies not only from India but also from international agencies. The managers and the project team had to face many technological and managerial challenges at various stages of the mission. In this paper we present the challenges in conceiving a space science mission in India, and methods adopted to overcome them to make the mission successful. This may help in planning and executing future space science missions, more efficiently, meeting the growing demands from the scientific community involved in the frontier areas of space research.

印度专用太空天文台 AstroSat 已于 2020 年 9 月 28 日成功完成了五年的太空运行。 AstroSat 是一颗非常复杂的卫星，因为它是一个多波长天文台，拥有许多科学仪器。许多机构的传奇故事，包括印度空间研究组织、领导机构以及许多科学家和工程师，以优异的性能和非常令人满意的结果实现和运行了这项任务。这次任务产生了大量观测结果，从而加强了印度天文学家和国际天文学家的研究活动。正如预期的那样，它还激发了年轻科学家和理科学生的兴趣。该任务仍在轨道上继续为天体观测做出贡献。AstroSat 是许多机构的共同努力，不仅来自印度，而且来自国际机构。在任务的不同阶段，经理和项目团队不得不面对许多技术和管理挑战。在本文中，我们介绍了在印度构思空间科学任务所面临的挑战，以及为使任务成功而克服这些挑战所采用的方法。这可能有助于更有效地规划和执行未来的空间科学任务，满足参与空间研究前沿领域的科学界不断增长的需求。以及为克服这些问题而采取的方法，使任务成功。这可能有助于更有效地规划和执行未来的空间科学任务，满足参与空间研究前沿领域的科学界不断增长的需求。以及为克服这些问题而采取的方法，使任务成功。这可能有助于更有效地规划和执行未来的空间科学任务，满足参与空间研究前沿领域的科学界不断增长的需求。
