深空探测的几个问题

1．深空探测的目的和必要性 深空探测又称宇宙航行．包括空间探测器在太阳系内的行星际空间航行（航天）和太阳系外的恒星际空间航行（航宇）。这里所谓“深空”是指距地球等于或大于地月距离（38．4万公里）的空间。     

2000年航天大事记

1月(1)波音公司同意收购卫星制造商休斯空间与通信公司，收购费37.5亿美元。这笔交易在11月完成，波音公司购入该公司后组建了波音空间系统公司。(2)全球星公司开通移动卫星电话业务。2月(1)10日，日本的M-5火箭在鹿儿岛航天中心发射本国的天文-EX射线卫星时失败，卫星坠毁。日本宇宙科学研究所认为火箭的第一级发生故障，导致火箭出现姿态问题，而火箭的第二和第三级没有能力对错误进行修正，卫星最终未能进入预定轨道，而是进入了距地面仅80公里的空间。这次失败使日本的航天计划又一次遭受沉重打击。(2)12日，亚洲蜂窝卫星公司的盖路达…     

中国航天国际合作的成功发展

党的十一届三中全会以来，改革开放政策为我国航天事业的对外交流与国际合作，提供了很好的机遇。１９７７年９月，中国航天技术代表团首次访问欧洲，赴法国进行了空间技术考察。１９７８年８月和１１月，航天代表团访问了日本和美国航宇局。从此长期与西方各国在宇航方面几乎隔绝、很少来往的局面终于打破了。８０年代中期以来，我国航天系统每年约有２０００人次出访、约４００人次出席各种国际学术会议，进行技术交流，商谈技术贸易合作。近年来，在巴黎、法思巴勒、新加坡和汉诺威等处举行的大型国际航空航天博览会上，我国航天部门都派…     

国外国际空间法的教学与研究

国际空间法创立于20世纪50年代,是国际法的一个年轻分支。联合国在苏联于1957年发射第一颗人造地球卫星后不久,就在各国的努力下,迅速构建了以《外空条约》等5个条约为核心、以联大5项决议(宣言)为补充的国际外空法框架。外空法在区域层面(如欧空局、独联体等组织)和国家层面都     

国外与空间碎片有关的国际空间法热点问题研究述评

与空间碎片有关的国际空间法研究主要包括对空间碎片的定义、空间环境保护制度、空间物体的登记制度及空间损害赔偿责任制度等问题的研究。联合国和平利用外层空间委员会法律小组经过多年的研究和讨论,对于“空间物体”与“空间碎片”的定义及其关系问题的研究基本上获得了国际社会的普遍认可,     

The intergovernmental agreement on the International Space Station

After Russia joined the ISS programme in 1994 it was realized that a new intergovernmental agreement would be needed in order to clarify the roles and responsibilities of all the partners. The Head of the Russian delegation to the negotations on the agreement between 1994 and 1998 here describes the various steps taken to reach it. As well as requiring legislation on new areas such as national criminal jurisdiction, the negotiations had to take account of the differing legal norms and cultures in all the various countries party to the agreement, but principally Russia and the USA. The final part of the article presents an up-to-date overview of the vital statistics and capabilities of, and type of work expected to be performed on, the ISS.     

我的国际空间大学生活

国际空间大学（Internationa1SpaceUniversity,ISU）自创办以来,已先后在不同国家举办了二十四届暑期班（SummerSessionProgram,SSP）。为世界航天界培养、输送了大量人才,从这里走出的毕业生已经成为世界各国航天领域的中坚力量,很多人担任着关键管理岗位或技术岗位。     

Research progress and accomplishments on International Space Station

The first research payloads reached the International Space Station (ISS) more than two years ago, with research operating continuously since March 2001. Seven research racks are currently on-orbit, with three more arriving soon to expand science capabilities. Through the first five expeditions, 60 unique NASA-managed investigations from 11 nations have been supported, many continuing into later missions. More than 90,000 experiment hours have been completed, and more than 1,000 hours of crew time have been dedicated to research, numbers that grow daily. The multidisciplinary program includes research in life sciences, physical sciences, biotechnology, Earth sciences, technology demonstrations as well as commercial endeavors and educational activities. The Payload Operations and Integration Center monitors the onboard activities around the clock, working with numerous Principal Investigators and Payload Developers at their remote sites. Future years will see expansion of the station with research modules provided by the European Space Agency and Japan, which will be outfitted with additional research racks.     

美国航天飞机商业化的若干问题

航天飞机是一种能够运送人类往返于外层空间和大气空间的特殊运载工具，具有兼顾军用和民用并且造价昂贵的特点。美国是目前世界上唯一拥有这一运载工具的国家。从航天飞机的背景来看，它虽然是美国和苏联在冷战时期进行技术竞赛所带来的空间成就，但

Solar particle events and the International Space Station

The high inclination orbit for the International Space Station poses a risk to astronauts on EVA during occasional periods of enhanced high energy particle flux from the sun known as Solar Particle Events. We are currently unable to predict these events within the few-hour lead time required for evasive action. Compounding the threat is the fact that station construction occurs during increasing solar activity and through the peak of the solar cycle. In this paper we present an overview of the risk, the current methods to provide forecasts of SPEs, and potential risk mitigation options.
