1999年11月20日,我国首次成功发射了名为“神舟号”的可载入太空飞船,飞船经过21小时太空运行后,按预定计划在预定地点顺利着陆。这标志着我国在掌握了近地轨道返回式卫星、地球同步轨道卫星、太阳同步轨道卫星发射测控技术之后,又基本上掌握了载入航天这一高难技术。 在观看了飞船发射和回收的电视后,许多观众提出了各种各样的问题:飞船为什么不载人?飞船为何不像船?火箭为何站着上塔?新型运载火箭模样与以前为什么不同?带着这些疑
On November 20, 1999, for the first time in China, a spacecraft capable of loading was named “Shenzhou”. After 21 hours of space operation, the spacecraft landed at a scheduled location according to a predetermined schedule. This indicates that after mastering the near-Earth orbiting return satellite, the geosynchronous orbit satellite and the solar synchronous orbit satellite emission measurement and control technology, China has basically mastered the high technology of loading space. After watching the TV launched and recovered by the spacecraft, many viewers raised a variety of questions: Why the spacecraft is not manned? Why the spacecraft does not resemble a ship? Why is the rocketry standing on the tower? Why is the new launch vehicle different from the previous one? With these doubts
