天问：一切将怎样结束？

这是时间终结后的第三周。在宇宙学和其他未知结局后宇宙会议上，亚当斯教授站在焦躁不安的听众面前，自呜得意地告诉他们已众所周知的事情。在一次被称为“大扑哧”的令人不安的事件中，宇宙以他的理论所预测的精确方式告终。     

《消失的艾斯蜜》

这是一部奇异的,哀伤的,不可思议的优秀小说。我宁愿相信只在书中,亲人之间才会有这样的举动。但不幸的是,出卖、嫉妒和背叛在真实生活中也同样普遍存在。这是一部令人感到不寒而栗的书,在未来的很长一段时间内我都无法不时常想起这部书。     

Aspects of Global Magnetospheric Processes

Magnetospheric global modeling is a method to link observations from distant regions via physical laws and has long played a unique and crucial role in space physics. It, different from computer simulations, represents the highest level of abstraction of the physical understanding of the processes that cause observed phenomena. It results in various specific models. While it appears in the form of cartoons, it is based on and has to be qualitatively consistent with physical laws. With the advancement of computer simulations, clues to the connection between physical laws and observation can be perceived much more easily than as ever before. However, computer simulation results are highly dependent on the used boundary conditions and numerical methods which may or may not represent the reality, even if the initial conditions are properly set. Therefore, simulations can easily mislead the investigations. Furthermore, a simulation result needs to be examined using diagnostic tools, such as field line tracing and streamline tracing programs. There are uncertainties in these diagnostic methods. The errors can be very large in certain areas under certain conditions. For example, a small error may link two different field lines or stream lines. The interpretations of the simulation results can be misled by these errors. The knowledge of global modeling can be useful in identifying the inconsistencies in the simulations and the flaws in the theoretical interpretation from the simulations. This review-tutorial article outlines the principles of the global modeling and discusses the successes and flaws of several global models.

Deuterium-free water (1H2O) in complex life-support systems of long-term space missions

Heavy water containing deuterium displays toxic property. It is stated that any quantity of a heavy isotope of hydrogen--deuterium--is undesirable to animals and plants. It was earlier shown by us that physical-chemical life support systems on board the "MIR" station fractionate (change) isotopes of hydrogen, oxygen and carbon. Therefore, the problem of regenerative systems in habitable space objects should include removal, from water, of a heavy stable isotope of hydrogen--deuterium. In this article we consider one method of obtaining deuterium-free water--decomposition of distillate water in an electrolyser to hydrogen and oxygen with subsequent synthesis in a catalytic or high-temperature reactor. The influence of deuterium-free water on the growth and development of Arabidopsis thaliana and Japanese quail is investigated. It is shown that with the help of the electrolysis method it is possible to fabricate water containing 80% less deuterium in comparison with SMOW. Experimentally, it is proved on a culture of Arabidopsis thaliana and Japanese quail that water with reduced contents of deuterium (80%) displays positive biological activity.     

Human characteristics of pair assembly work in a microgravity environment

This research focuses on analyzing the human characteristics of pair assembly work in a microgravity environment. To obtain the necessary data, two groups of test subjects participated in an experiment in a pseudomicrogravity environment, and how such factors as work allotment, sizes of assembled objects, and conditions of parts influence the work efficiency were studied. The results show when the assembled object is smaller that it is easier to change the object's position and that workers can move it to an appropriate site and work easily. If the assembly object is attached to an object with very large mass, the work allotment does not result in a difference in work time. As for positioning the objects, step-saving processes can shorten the work time. For instance, if a part can be put so that both ends automatically touch the proper spots, time can be shortened.

W.W.W. MOON? The why, what and when of a permanent manned lunar colony

Several reasons for going back to the Moon are listed: scientific study of our natural satellite, Earth and in general the Solar System; exploitation of the resources of Outer Space; geopolitical considerations that made Apollo possible and are still valid in the long term; advancement of manned spaceflight, as robot-based exploration is time-wise inefficient and politically negligible. Technological, organisational and legal challenges are then outlined. After a discussion of human physiology, building materials and transportation of people and goods, an underground polar location is proposed as settlement site, either within kilometre-size lava tubes or man-made caves. An analysis of spaceflight history is conducted to determine a target date for returning to the Moon to stay. In the absence of political or commercial competition, experience indicates the last decades of the XXI century. To shorten this timescale, it is recommended to focus on accomplishing the task of establishing a reliable lunar travel and settlement system, rather than developing new technologies: simplifying the goals of each single step forward (as was the case of the Clementine mission) and concentrating on production-ready (or almost-ready) equipment (compare the ill-fated X-33 to the dependable Soyuz capsules).
