Shuttle Radar Topography Mission

The Shuttle Radar Topography Mission, which flew aboard NASA's Space Shuttle Endeavour during an 11-day mission in 2000, made the first near-global topographical map of Earth, collecting data on nearly 80 percent of Earth's land surfaces. The instrument's design was essentially a modified version of the earlier Shuttle Imaging Radar instruments with a second antenna added to allow for topographic mapping using a technique similar to stereo photography.航天飞机雷达地形测量任务，于2000年搭载美国国家航空航天局（NASA）的奋进号航天飞机执行为期11天的任务，首次绘制了地球的近全球地形图，收集了地球陆地表面近80%的数据。该仪器的设计本质上是对早期航天飞机成像雷达仪器的改良版本，增加了一个第二天线，以实现类似于立体摄影术的技术进行地形测绘。
