Innovation and change? The evolution of Europe's small satellite manufacturers

Since the 1980s a trend has emerged to contain the cost of space missions, which has favored trials in the construction and launch of small satellites. This effort has considerably reduced the cost of the satellites because the construction process uses both traditional components and important technological innovations. There have also been market openings for small satellites, both within the telecommunication sector and for scientific missions and those related to Earth observation. This paper contains the results of a survey of the largest manufacturers of small satellites in Europe and investigates how far (if at all) they have changed the structure of the European space industry. It finds that, through the acquisition of small satellite manufacturers, traditional large companies operating in the field of space in Europe have secured for themselves important technological innovations and market opportunities, while maintaining their oligopolistic position.

Crew autonomy for deep space exploration: Lessons from the Antarctic Search for Meteorites

Future piloted missions to explore asteroids, Mars, and other targets beyond the Moon will experience strict limitations on communication between vehicles in space and control centers on Earth. These limitations will require crews to operate with greater autonomy than any past space mission has demonstrated. The Antarctic Search for Meteorites (ANSMET) project, which regularly sends small teams of researchers to remote parts of the southern continent, resembles a space mission in many ways but does not rely upon a control center. It provides a useful crew autonomy model for planners of future deep space exploration missions. In contrast to current space missions, ANSMET gives the crew the authority to adjust competing work priorities, task assignments, and daily schedules; allows the crew to be the primary monitor of mission progress; demands greater crew accountability for operational errors; requires the crew to make the most of limited communication bandwidth; adopts systems designed for simple operation and failure recovery; and grants the crew a leading role in the selection and stowage of their equipment.

实行学分制的探索与实践

高职高专教育是我国高等教育体系的重要组成部分。实行学分制教学管理制度已成为强化目标管理,以学生为本、因材施教、强化素质教育的必然趋势。本文在简要介绍学分制概况的基础上,以作者所在学校实行学分制的思路及做法,介绍了实施的部分内容,并对已经出现或可能出现的某些问题提出了解决办法。     

社会技术与自然技术的和谐图景

技术是人的本质存在形式。技术范畴已发生本体论上的外延,除自然技术外,还必然涵括社会技术范畴。社会技术的存在毋庸置疑,自学界提出社会技术的概念后,社会技术与自然技术的关系便成为技术哲学研究的崭新视角。和谐技术观是社会技术与自然技术关系之基。社会技术和自然技术在消解与融合、界限、可逆性等诸方面显现出和谐图景。
