The paper addresses the evolution of the Canadian Space Station Program between 1981 and 2003. Discussions with potential international partners, aimed at jointly developing the current International Space Station program, were initiated by NASA in 1982. Canada chose, through the further development of the technologies of Canadarm on the space shuttle, to provide and operate an advanced and comprehensive external robotics system for space station, and to use the space station for scientific and commercial purposes. The program was to become a corner-stone of the new Canadian Space Agency. The development phase of the Canadian Space Station Program has been completed and two of the three major elements are currently operational in space. 相似文献

The methods of automatic control of motion of a free-flight platform near the orbital space station are considered. The satellite-inspector intended for service of the International Space Station is an example of such objects. The algorithms of control of the platform motion along a trajectory specified by the space station operator are developed, and control of the station keeping mode for visual observation of the state of the space station's external surface is considered. The problem of control of a platform landing on a specially equipped docking unit of the orbital space station is also considered. 相似文献

To sustain the rate of extravehicular activity (EVA) required to assemble and maintain the International Space Station, we must enhance our ability to plan, train for, and execute EVAs. An underlying analysis capability has been developed to ensure EVA access to all external worksites as a starting point for ground training, to generate information needed for on-orbit training, and to react quickly to develop contingency EVA plans, techniques, and procedures. This paper describes the use of computer-based EVA worksite analysis techniques for EVA worksite design. EVA worksite analysis has been used to design 80% of EVA worksites on the U.S. portion of the International Space Station. With the launch of the first U.S. element of the station, EVA worksite analysis is being developed further to support real-time analysis of unplanned EVA operations. This paper describes this development and deployment of EVA worksite analysis for International Space Station (ISS) mission support. 相似文献

《Acta Astronautica》1993,29(12):931-944Experience with the Shuttle and free-flying satellites as technology test beds has shown the feasibility and desirability of using space assets as facilities for technology development. Thus, by the time the space station era arrives, technologists will be ready for an accessible engineering facility in space. Along with the scientific and commercial space development communities, the technology development community has been participating in defining requirements for this in-space facility. As the 21st century is approached, it is expected that many flights to the Space Station Freedom will carry one or more RT&E experiments. The experiments are likely to utilize both the pressurized volume, and the external payload attachment facilities. Based on the success of instrumenting the Shuttle itself to obtain ascent and descent aerothermodynamic data a unique, but extremely important, class of experiments will use the space station itself as an experimental vehicle. 相似文献

Russian Progress transport cargo vehicles have successfully been used in different space station programs since 1978. At present time, they play an important role in the International Space Station (ISS) project. Main tasks performed by the transport cargo vehicle (TCV) in the station program are the following: refueling of the station, delivery of consumables and equipment, waste removal, station attitude control and orbit correction maneuver execution. 相似文献

In isolated and confined environments, two important leadership roles have been identified: the task/instrumental role (which focuses on work goals and operational needs), and the supportive/expressive role (which focuses on morale goals and emotional needs). On the International Space Station, the mission commander should be familiar with both of these aspects of leadership. In previous research involving a 135-day Mir space station simulation in Moscow and a series of on-orbit Mir space station missions during the Shuttle/Mir program, both these leadership roles were studied. In new analyses of the Shuttle/Mir data, we found that for crewmembers, the supportive role of the commander (but not the task role) related positively with crew cohesion. For mission control personnel on the ground, both the task and supportive roles of their leader were related positively to mission control cohesion. The implications of these findings are discussed in terms of leadership on board the International Space Station. 相似文献

空间站能源系统并网供电技术研究 总被引:1,自引:0,他引:1
空间站结构复杂,通常由多个舱段组成,与飞船等飞行器进行交会对接后,各舱段和对接飞行器自有的能源系统可能会由于空间位置及相互遮挡等原因而无法满足自身供电需求,这就需要对舱体电源系统进行并网供电。文章论述了“天宫一号”目标飞行器与“神舟”飞船采用的并网供电方案,通过并联冗余及自动均流控制实现不同舱体间的功率传输;在此基础上,通过调研国外空间站并网供电技术,比较了空间飞行器组合体并网供电中的技术方案及特点,总结了目前空间站并网供电模式可采用的类型,最后提出了我国未来空间站并网供电可采取的方案。 相似文献
