The international community is undertaking science and technology studies for the next generation of X-ray astronomy satellites. While there is basic agreement concerning required improvements over the current capabilities, there are inevitable trade-offs that must be made to get the best scientific return within the constraints of technological development and cost. Two major science and technology studies are currently underway supported by scientists and engineers: Constellation-X in the U.S.A. and XEUS in Europe. Cross-fertilzation between these studies is likely to result in a joint mission, and discussions to this end have already commenced. I am a member of the 'Galaxies and Clusters' Science Panel for the Constellation-X project, and have proposed that the dynamics of X-ray emitting gas in galaxies will be important science for the new missions. This science imposes particularly stringent constraints on key requirements: sensitivity, spatial and spectral resolution, and field of view. This grant application requests the travel and subsistence support necessary for me to participate in the work of the panel during a particularly critical time as we move from technology studies into mission definition.

国际社会正在开展下一代X射线天文卫星的科技研究。虽然就当前能力所需的改进达成了基本一致，但为了在技术发展和成本的限制下获得最佳科学回报，必须进行不可避免的权衡。目前，科学家和工程师正在支持两项重大科学技术研究：美国的 Constellation-X 和欧洲的 XEUS。这些研究之间的交叉融合很可能会导致联合任务，为此目的的讨论已经开始。我是 Constellation-X 项目“星系和星团”科学小组的成员，并提出星系中 X 射线发射气体的动力学将成为新任务的重要科学。这门科学对关键要求施加了特别严格的限制：灵敏度、空间和光谱分辨率以及视场。该拨款申请要求我在从技术研究转向任务定义的特别关键时期参与小组的工作所需的旅行和生活支持。
