This award will support a two-year cooperative research project between Professor Christopher T. Russell, Institute of Geophysics and Planetary Physics, University of California, Los Angeles (UCLA), and Professor Willibald Riedler, Institute for Space Research, Austrian Academy of Sciences, Graz, Austria, and their respective research groups. The scientists will jointly study available data on the interaction of the solar wind with small bodies in the solar system. The scientific objectives are (1) experimental investigations of the influence of comets, asteroids, and meteor streams on the interplanetary medium; (2) modelling of the potential mechanisms of interaction between the interplanetary medium and these minor bodies of the solar system; and (3) development of new data processing and analysis methods to improve the investigation of events which might be caused by these interaction processes. Professor Riedler and his Austrian colleagues were successful in probing Halley's comet in 1986 with instruments on board the Soviet spacecraft VEGA 1 and 2, and are preparing instruments for the Phobos mission to Mars, expected to be launched by the U.S.S.R. in 1988. Through this U.S.-Austrian cooperative project, Professor Russell and his research group at UCLA have access to the VEGA data from Comet Halley and to the personnel who can assist in working with those data. Professor Russell also expects to have access to magnetic field data from the Soviet Mars 2, 3, and 5 missions as a result of this collaboration. Analysis of these latter data should lead to a greater understanding of the solar wind interaction with Mars, as well as help prepare for future Mars missions. The scientists also plan to exchange modelling results and to develop improved software for scientific analysis and on-board processing of data. Professor Russell and members of his research group have been active in observational and theoretical studies related to the interaction of the solar wind with solar system bodies for many years. Professor Riedler and his colleagues have been involved in parallel studies. Cooperation between the groups should enhance their respective research programs considerably. Funds from this award would support necessary transportation and subsistence expenses for the U.S. principal investigator and members of his research group. The Austrian Science Foundation (FWF) is providing counterpart support for the project and has approved the inclusion of this activity under the Memorandum of Understanding between the NSF and the FWF.

该奖项将支持加州大学洛杉矶分校(加州大学洛杉矶分校)地球物理和行星物理研究所Christopher T.Russell教授和奥地利格拉茨奥地利科学院空间研究所威廉·里德勒教授及其各自研究小组之间为期两年的合作研究项目。科学家们将共同研究太阳风与太阳系中的小天体相互作用的现有数据。科学目标是：(1)实验研究彗星、小行星和流星流对行星际介质的影响；(2)建立行星际介质与太阳系这些小天体之间相互作用的潜在机制的模型；(3)开发新的数据处理和分析方法，以改进对这些相互作用过程可能引起的事件的调查。里德勒教授和他的奥地利同事在1986年成功地用苏联航天器织女星1号和2号上的仪器探测了哈雷彗星，他们正在为苏联预计于1988年发射的火卫一火星任务准备仪器。通过这一美国-奥地利合作项目，拉塞尔教授和他在加州大学洛杉矶分校的研究小组可以访问哈雷彗星的织女星数据，并联系到能够协助处理这些数据的人员。拉塞尔教授还希望通过这次合作能够获得苏联火星2号、3号和5号任务的磁场数据。对后一类数据的分析应该有助于更好地理解太阳风与火星的相互作用，并有助于为未来的火星任务做准备。科学家们还计划交换建模结果，并开发改进的软件，用于科学分析和数据的机上处理。多年来，拉塞尔教授和他的研究小组成员一直活跃在与太阳风与太阳系天体相互作用有关的观测和理论研究中。里德勒教授和他的同事们一直在进行平行研究。两个小组之间的合作应该会大大加强各自的研究计划。这项奖励的资金将用于支付美国首席调查员及其研究小组成员的必要交通和生活费。奥地利科学基金会(FWF)正在为该项目提供对应的支持，并已批准将这项活动列入国家科学基金会和FWF之间的谅解备忘录。
