The SDSS project finished its originally planned operations in June 2005. We began the construction of the instruments in 1993 and the operation in 2000. During the time it attained imaging for 115% of the planned region and spectroscopy for 76%. Somewhat lower achievement of the spectroscopy is due to poor weather in the winter and spring of 2004 and 2005. We began a new programme, SDSS-II for another three years from July 2005, for the purpose primarily to fill the missing observed regions, supplemented with two new projects, for which SDSS turns out to be extremely useful from our experience.To date we have made public the imaging data for 6670 square degrees that comprises 180 million astronomical objects, a half of them being galaxies, and spectra of 850 thousand galaxies. The present Grant-in-Aid project corresponds to the mid to the latest part of the original project and SDSS-II.Analyses of the acquired data were made from time to time, and our achievements have already satisfied well the scientific goals set in the beginning of the project. The data we acquired are and will be used world-widely throughout this century for precision astronomical sciences. The SDSS project is regarded as the most successful scientific project in our time. The members of the Grant-in-Aid authored 108 papers that have already received over 16000 citations in the community.The science produced ranges from cosmology, large-scale structure of the universe, high redshift quasars and studies for high redshift universe, galactic astronomy, stellar science, especially that of low temperature stars, and asteroid science. Probably the most important is the quantitative verification that our universe and its evolution are described well by the model of the universe dominated by cold dark matter and dark energy. This allowed our basic understanding of the Universe. The result also indicates the direction and objectives to be studied with large-scale astronomical projects in the future.

SDSS项目于2005年6月完成了原计划的运行。我们于1993年开始建造仪器，并于2000年运行。在此期间，它实现了计划区域115％的成像和76％的光谱覆盖。光谱学成绩稍低是由于 2004 年和 2005 年冬季和春季的恶劣天气。我们从 2005 年 7 月起又开始了一个新的计划，SDSS-II，为期三年，主要目的是填补缺失的观测区域，补充有两个新项目，根据我们的经验，SDSS 对这两个项目非常有用。迄今为止，我们已经公开了 6670 平方度的成像数据，其中包括 1.8 亿个天体，相当于它们是星系，以及85万个星系的光谱。目前的资助项目对应于原项目和SDSS-II的中期到最新部分。我们不时对所获得的数据进行分析，我们的成果已经很好地满足了项目中设定的科学目标。项目的开始。我们获得的数据在本世纪将在全世界范围内用于精密天文科学。 SDSS 项目被认为是我们这个时代最成功的科学项目。资助计划的成员撰写了 108 篇论文，已在社区获得超过 16000 次引用。科学成果涵盖宇宙学、宇宙大尺度结构、高红移类星体以及高红移宇宙研究、银河天文学、恒星科学，特别是低温恒星科学和小行星科学。也许最重要的是定量验证，即我们的宇宙及其演化可以通过由冷暗物质和暗能量主导的宇宙模型很好地描述。这使我们对宇宙有了基本的了解。这一结果也指明了未来大型天文工程的研究方向和目标。
