神舟“四号”遭遇罕见严寒在祖国巴丹吉林沙摸西沿,嘉峪关长城以北,一座高耸人云的火箭发射塔昂首矗立,直指太空。这,就是中国酒泉载人航天发射场。2002年12月,承载着“神舟”四号飞船的长征二号F火箭,矗立在发射塔架上。这是载人航天工程实施以来技术要求最高、参试系统最全、难度最大的一次飞行试验。然而,发测站却面临载人航天发射以来最为严峻的考验——发射场遇到了有史以来罕见的严寒,最低气温接近
Shenzhou “No. 4 ” Encounter a rare cold In the motherland Badain Jialisha along the west, north of the Great Wall of Jiayuguan, a towering towering rocket launcher tower stands, pointing to space. This is the Chinese Jiuquan manned space launch site. In December 2002, the Long March II F rocket bearing the “Shenzhou 4” spacecraft was erected on the launch tower. This is the highest technical requirements since the implementation of manned space project, the most complete test system, the most difficult flight test. However, the station is facing the most severe test since the manned space launch - the launch site has encountered a rare cold ever, and the minimum temperature approaches
