Measuring the economic benefits of a national planetary protection policy to regulate future private space activities between Earth and Mars: Results of a contingent valuation survey in Greece

The emergence of private space actors may soon enable the growth of the novel market segments of space research and exploration, space resources utilization, and human access to space. The interdisciplinary field of Planetary Protection has to keep up with these advances. Planetary Protection is defined as a set of guidelines that aim to prevent the forward contamination of celestial bodies with biological material from Earth and the backward contamination of the terrestrial biosphere with extraterrestrial biological material. As space entrepreneurs acquire and develop the resources and competencies for commercial access to space, significant questions are expected to be raised in the future with respect to potential forward and backward contamination issues, particularly with respect to activities between Earth and Mars. Although such private activities do not seem to pose a serious Planetary Protection threat at the moment, certain preparatory steps need to be taken in order to prudently inform the relevant policy-making procedures. This work describes the application of the Contingent Valuation Method, a useful tool of the environmental economics discipline, with the aim of demonstrating a novel approach to estimate the economic valuation of the external benefits of preventing forward and backward contamination between Earth and Mars. Particularly, via a survey specifically developed for this purpose, a set of questions are used to elicit the perceived economic value that respondents place on the prevention of forward and backward contamination; the survey is administered to a national probability sample in Greece, and the generated data is processed through statistical analysis. The Contingent Valuation Method is a popular and well-established stated preference valuation technique; these techniques are often the more suitable choice for ex-ante valuations of future changes, and are currently the only known approach to capture all the aspects of the economic value of non-market goods. Through an initial proof-of-concept in Greece, the goal of this work is to provide useful insights on the expected external benefits of a national Planetary Protection policy to regulate future private space activities between Earth and Mars, and to encourage a larger-scale application of this tool in other countries around the world.     

动磁式线性电机理论研究与测试技术

本文以昆明物理研究所的SC100H线性斯特林制冷机为研究对象,对该制冷机采用的动磁式线性振荡电机磁路特性进行了理论与实验研究。建立了电机理论模型,对模型进行了结构简化以便于分析计算,利用等效磁路法和机电能量转换原理,分析电机推力特性与动子相对位置等的关系,利用拉力测试系统对电机在不同输入电流的推力特性进行了测试,测试结果与理论值很好的吻合,从而为电机结构参数和运行参数的设计优化提供了设计参考与依据。     

Current and future activities in education and public outreach at the Observatoire de Haute Provence

The Haute Provence Observatory has for primary mission the operation of telescopes, up to two meters in diameter, for the astrophysics community, and the measurements of various upper atmosphere parameters for the geophysics community. An education and outreach program has been developed with several reached: from school pupils to post-doctorate students, teachers, and the general public. In the recent years we put emphasis on the formation of teachers and on the renewal of the general public visit. Given the wide range of education and outreach activities we cover, we had to develop a relation network with individuals, amateurs, teachers and institutions, amplifying our efforts. For the future, we will try to make an optimal use of the resources available in the St Michel l’Observatoire area, taking steps to reach an agreement with the neighbouring “Centre d’Astronomie”, a structure devoted to education and public outreach belonging to the local authorities.
