在过去的三十年里，高能天体物理学出现了爆炸性的发展。我们发现X射线天文学是理解我们宇宙不可或缺的工具。这门学科已经成熟，未来的X射线天文台必须更加专业化。ASCA系统地开发了2keV以上波段的高分辨率光谱成像，带来了许多新的天体物理知识。ASCA在研究隐藏在致密物质背后的来源方面也发挥了特别重要的作用。ASCA的继任者Astro-E定于2000年由空间和宇航科学研究所(ISAS)用其新开发的M-V火箭(小川和井上1997年)发射。我们新的Astro-E天文台在0.5keV至600keV的宽能量范围内具有高能量分辨率和高灵敏度。天文台的总体重点是在较高的能量下提供较大的收集区，具有足够好的角分辨率，以避免混淆限制。本文简要介绍了Astro-E仪器的性能。
The past three decades have seen an explosion in high-energy astrophysics. We have found X-ray astronomy to be an indispensable tool in understanding our Universe. The discipline has become mature, and future X-ray observatories must be more highly specialized. High-resolution spectroscopic imaging in the band above 2 keV, systematically exploited by ASCA, has led to much new astrophysical knowledge. ASCA has also been playing a particularly important role in studying sources hidden behind dense material. Astro-E, the successor of ASCA, is scheduled for launch in the year 2000 by the Institute of Space and Astronautical Science (ISAS) with its newly developed M-V rocket (Ogawara & Inoue 1997). Our new Astro-E observatory features high energy resolution and high sensitivity over the broad energy range 0.5 keV to 600 keV. The general emphasis of the observatory is to provide large collecting areas at higher energies, with angular resolution good enough to avoid the confusion limit. This paper provides a brief description of the performance of the Astro-E instruments.
