【摘要】 现代紫外天文学的观测波段是３１００ ～１００?， 和Ｘ 射线相接。紫外观测要把望远镜放到１５０ ｋｍ高度以上， 以避开臭氧层和大气吸收。９０ 年代发射的专用紫外空间探测器有Ａｓｔｒｏ － １ ， Ａｓｔｒｏ － ２ ，ＩＵＥ， ＥＵ ＶＥ。在ＨＳＴ 和ＴＲＡＣＥ 上也安装有紫外空间探测器。这些紫外空间观测已覆盖了全部紫外光谱。１９９９ 年６ 月２４ 日发射升空的ＦＵＳＥ 卫星是ＮＡＳＡ 的“起源计划” 项目， 将通过氘或“重氢”的探测来研究轻元素丰度， 以探索大爆炸宇宙学理论的宇宙形成和演化更多还原

【Abstract】 This paper reviews the past, present, and future of the space explorers for ultravoilet astronomy.Ultravoilet astronomy explorers launched and planned are described. The observing wavelengths of modern ultravoilet astronomy are in the range of 3100?～100? in connection with X-ray.Telescopes for ultraviolet observation are required to be put higher than 150 km well above the ozone and oxygen layers. The devoted ultraviolet space explorers launched in the 1990s are Astro-1, Astro-2, IUE, and EUVE. In addition, there are ultraviolet telescopes onboard the HST and TRACE satellites as well. Ultraviolet Observations in space have been made in the whole spectrum of ultraviolet astronomy. The FUSE satellite is part of NASA′s “Origins Program”. It is aimed at the exploration of one of the fundamental parameters, the abundances of light elements in the formation and evolution of the universe through the studies of deuterium, or “heavy hydrogen”, which was created solely in the Big Bang.更多还原
