中国正在建设的“十一五”国家重大科技基础设施建设项目——500 m口径球面射电望远镜(FAST)将成为世界上最 大、最灵敏的单口径射电望远镜, 它有望在中性氢巡视、脉冲星搜索、国际VLBI网联测及地外生命搜寻等重要前沿领域取得 突破。首先对FAST工程的建设内容及科学目标进行了总体介绍，随后重点叙述了截至2015年5月工程建设的最新进展, 最后 对FAST工程的发展做出了展望。

 Five-hundred-meter Aperture Spherical radio Telescope (FAST) is a Chinese mega-science project to build the largest single dish radio telescope in the world. FAST will enable astronomers to jump-start many science goals, for example, surveying the neutral hydrogen in the Milky Way and other galaxies, detecting faint pulsars, hearing the possible signals from other civilizations, etc. The  construction content and scienti?c objectives of FAST are overviewed as well as the latest progress and prospects.
