经过23年多的开发,哈勃太空望远镜于1990年4月发射升空。哈勃太空望远镜重11.11吨,长15.9米,大小相当于一辆大型客车。它高居于地球朦胧的大气层之上610千米处,环绕地球运行的速度为8千米/秒,绕地球的轨道运行1周需时97分钟。通过望远镜所收集的图像和信息,传播14.5万千米,经由人造卫星和地面数据传输线路,最后到达位于美国巴尔的摩市的太空望远镜科学研究中心。
After more than 23 years of development, the Hubble Space Telescope was launched in April 1990. Hubble Space Telescope weighs 11.11 tons, 15.9 meters long, the size of a large passenger car. It is located 610 km above the hazy atmosphere of the Earth, traveling around the Earth at a speed of 8 km / s, orbiting the Earth for 97 days. The images and information collected through the telescopes spread 145,000 kilometers via satellite and terrestrial data transmission lines and finally to the Space Telescope Science Research Center in Baltimore, USA.
