受政治、经济、军事和技术等多种因素的影响,2004年全球只发射了19颗军用卫星,与2003年有28颗军用卫星升空相比少了许多。但这一年中也有几项重要的军事航天活动,尤其是年底升空的欧洲首颗第2代照相侦察卫星“太阳神-2A”,给军事航天界挽回了一些“颜面”。 Influenced by many factors such as politics, economy, military affairs and technology, only 19 military satellites were launched globally in 2004, much less than the 28 military satellites launched in 2003. However, during the year there were also several important military space activities, in particular the “Apollo-2A”, the first European second-generation photo reconnaissance satellite launched by the end of the year, which has redeemed some of the “face” of the military spaceflight community.
