The Astro-E satellite was launched on Feb. 10, 2000, trying to be the Japanese fifth X-ray astronomical satellite, but failed to be it according to an accident in its launcher. It was intended to be a international X-ray observatory in orbit having a capability for high sensitivity observations with the finest energy resolution ever achieved in a very wide energy range. A part of the scientific instruments were developed under a Japan-US collaboration, and the final completion of the development, the instrumental calibrations before launch, the final performance verification before the launch after mounting them in the spacecraft and so on were done in the latest two years. By this grant-in-aid, participation of Japanese members in the final completion and tests of the instruments in US, taking part of US members in the final integration tests in Japan, attendance of Astro-E team members in meetings for reviews and investigations on current issues and so on were supported!. The developments were performed collaboratively by all the Japan-US members and the aid by this budget was very useful. Furthermore, this development yielded new results on high-energy-photon detectors and presentations of them in international conferences were also supported. In parallel to those activities on the instrumental developments, investigations on how to maximize the scientific yields have been done by organizing a science working group composing of leading scientists from Japan, US and Europe. In particular, meetings on collaborations of the Astro-E project with the European Space Agency were held and participation of the team members were supported by this grant in the last fiscal year. Although the launch failed, the spacecraft development and the international collaborations were very fruitful.

Astro-E卫星于2000年2月10日推出，试图成为日本的第五X射线天文卫星，但根据其发射器中的一次事故，未能成为它。它的目的是在轨道上是一家国际X射线天文台，具有高灵敏度观察的能力，其能量范围非常广泛。科学仪器的一部分是在日本 - 美国协作中开发的，开发的最终完成，启动前的仪器校准，在将它们安装在航天器上后发布前的最终性能验证，等等是在最近的两年中完成的。通过这笔赠款，日本成员的参与最终完成和对美国工具的测试，使美国成员参加了日本的最终集成测试，Astro-E团队成员参加了会议，以供有关当前问题的审查和调查，等等！这些发展都是由所有日本美国成员共同进行的，该预算的援助非常有用。此外，这一发展还为高能 - 光子检测器及其在国际会议中的介绍提供了新的结果。与那些关于乐器发展的活动的同时，通过组织一个科学工作组，由日本，美国和欧洲的主要科学家组成科学工作组，对如何最大化科学收益率进行了调查。特别是，举行了与欧洲航天局的Astro-E项目合作的会议，并在上一个财政年度得到了这笔赠款的支持。尽管发布失败了，但航天器开发和国际合作却非常富有成果。
