商业化和专业化——浅析澳大利亚航空工业

澳大利亚是生产飞机较早的国家之一,其自行设计的第一架飞机于1910年试飞。澳大利亚航空工业1936年以前为创始期,在二战期间得到迅速发展:先后自行设计制造或仿制英、美战斗机多种,总数近2000架,从业人员最多时曾达到4.4万人。但战后整个航空工业迅速收缩,到1948年,从业人数降至4100人。在政府的支持下,澳大利亚航空工业根据自身的条件开展小型民用飞机和导弹的设计制造工作。     

波音公司研发微小卫星

波音公司研发的1颗微小卫星——CubeSat试验台1（CSTB1）——于4月17日搭乘“第聂伯’’火箭从哈萨克斯坦的拜科努尔发射场发射升空。CSTB1重约0．9千克，有4台微处理器，2个独立的无线电通信系统，2块大容量可充电锂电池，1部可展开天线，1套复杂的控制系统（利用太阳和磁场传感器确定航天器的姿态），1套使用磁扭矩线圈的简单姿态控制系统和包含传感器和电子仪器的多功能仪表板。     

The Interplanetary Internet: a communications infrastructure for Mars exploration

A strategy is being developed whereby the current set of internationally standardized space data communications protocols can be incrementally evolved so that a first version of an operational "Interplanetary Internet" is feasible by the end of the decade. This paper describes its architectural concepts, discusses the current set of standard space data communications capabilities that exist to support Mars exploration and reviews proposed new developments. We also speculate that these current capabilities can grow to support future scenarios where human intelligence is widely distributed across the Solar System and day-to-day communications dialog between planets is routine.     

Research priorities and plans for the International Space Station-results of the 'REMAP' Task Force

Recent events in the International Space Station (ISS) Program have resulted in the necessity to re-examine the research priorities and research plans for future years. Due to both technical and fiscal resource constraints expected on the International Space Station, it is imperative that research priorities be carefully reviewed and clearly articulated. In consultation with OSTP and the Office of Management and budget (OMB), NASA's Office of Biological and Physical Research (OBPR) assembled an ad-hoc external advisory committee, the Biological and Physical Research Maximization and Prioritization (REMAP) Task Force. This paper describes the outcome of the Task Force and how it is being used to define a roadmap for near and long-term Biological and Physical Research objectives that supports NASA's Vision and Mission. Additionally, the paper discusses further prioritizations that were necessitated by budget and ISS resource constraints in order to maximize utilization of the International Space Station. Finally, a process has been developed to integrate the requirements for this prioritized research with other agency requirements to develop an integrated ISS assembly and utilization plan that maximizes scientific output.     

航天飞机用的液体火箭助推器

用液体火箭发动机作为航天飞机助推器的设想虽然很早有人提出过,但被人们搁置了达20年之久.美国肮天局早期的结论认为液体火箭发动机不能承受海水浸渍.但自从“挑战者”号航天飞机固体助推器发生故障而导致灾难性事故之后,美国航天局又重新对液体助推器方案进行了考查,以了解这种方案能否对安全飞行有所改善,以及能否增加有效载荷.这段时间美国肮天局及其承包公司进行了论证,发现液体助推器有不少好处,例如一旦出现故障,实现中止飞行的可信度较高;可增加有效载荷,对低地球轨道     

导引头实物仿真技术

讨论了美国陆军导弹司令部在研制面空导弹时采用的导引头实物仿真技术.目前在导弹系统的研制过程中,人们受到很多限制,例如经费有限,需要进行可靠的系统试验,要求在逼真的环境,包括电磁干扰和抗干扰环境中评价系统等.导引头实物仿真试验能为解决上述问题发挥重要作用.介绍和讨论了射频、非红外成像和电-光波段的现有仿真设备及其性能;举例介绍了最近完成的仿真试验结果及其对降低导弹系统研制成本所起的作用.最后介绍了主要的仿真技术和美国陆军提高仿真器能力的未来计划.     

The European Astronaut Centre prepares for International Space Station operations

The European Space Agency (ESA) contribution to the International Space Station (ISS) goes much beyond the delivery of hardware like the Columbus Laboratory, its payloads and the Automated Transfer Vehicles. ESA Astronauts will be members of the ISS crew. ESA, according to its commitments as ISS international partner, will be responsible to provide training on its elements and payloads to all ISS crewmembers and medical support for ESA astronauts. The European Astronaut Centre (EAC) in Cologne has developed over more than a decade into the centre of expertise for manned space activities within ESA by contributing to a number of important co-operative spaceflight missions. This role will be significantly extended for ISS manned operations. Apart from its support to ESA astronauts and their onboard operations, EAC will have a key role in training all ISS astronauts on ESA elements and payloads. The medical support of ISS crew, in particular of ESA astronauts has already started. This paper provides an overview on status and further plans in building up this homebase function for ESA astronauts and on the preparation towards Training Readiness for ISS crew training at EAC, Cologne.
