受全球经济下滑的影响,近四年来世界卫星工业增长速度减缓,卫星发射总量减少。加上卫星制造大国美国以各种借口禁止发放美制卫星(及使用美国零部件的卫星)的出口许可证,使中国长征火箭承揽国际商业发射服务面临困境。面对多种因素带来的严峻挑战,中国航天界以变应变,力求在国际航天市场上站稳脚跟,谋求多元化新发展。 Affected by the global economic downturn, the world satellite industry has slowed down in the past four years and the total number of satellites launched has decreased. In addition, the United States, a large satellite manufacturing country, has on various pretexts banned the issuance of export licenses for US-made satellites (and satellites using US components), making it difficult for China’s Long March rocket to undertake international commercial launch services. Faced with the harsh challenges brought by many factors, China’s aerospace community has taken the strain and sought to gain a foothold in the international space market and seek diversified new developments.
