An Outline of Investigation of Space Medicine Problem and Its Mechanism

The human exploration of space is one of the great voyages of discovery in human history. For over forty years space exploration, human have gotten more profound knowledge about outer space and life phenomena, ranging from understanding and recognizing space to adapting and utilizing space. With these development, space medicine that aimed at studying effect of space environment on human health and ensuring the safety, health and effective working of human in space exploration, will become increasingly improved and matured.The contents of research will develop from the early phenomena observation of the effect of space environment on human physiology and biochemistry, and the effect definition, to the study of the mechanism of changes of cell, molecule, and gene, from the passive adaptation for space environment to taking the initiative countermeasures, in order to ensure the safety, health and effective working of astronauts during space flight.Space practices in the past forty years have confirmed that a variety of physiological and pathological changes have been found for organism exposed to space flight. These changes include cardiovascular dysfunction, bone loss,muscle atrophy, decline of immune function, endocrine function disorder and space motion sickness. In recent years, more attention has been focused on the study of the mechanism of these changes, especially the effects of space environment on cell, molecule and its gene expression. With the demand of China's manned space engineering task and continuous development, a series of studies on medical problem caused by space environment have been carried out.

MEP (Mars Environment Package): toward a package for studying environmental conditions at the surface of Mars from future lander/rover missions.

In view to prepare Mars human exploration, it is necessary to promote and lead, at the international level, a highly interdisciplinary program, involving specialists of geochemistry, geophysics, atmospheric science, space weather, and biology. The goal of this program will be to elaborate concepts of individual instruments, then of integrated instrumental packages, able to collect exhaustive data sets of environmental parameters from future landers and rovers of Mars, and to favour the conditions of their implementation. Such a program is one of the most urgent need for preparing human exploration, in order to develop mitigation strategies aimed at ensuring the safety of human explorers, and minimizing risk for surface operations. A few main areas of investigation may be listed: particle and radiation environment, chemical composition of atmosphere, meteorology, chemical composition of dust, surface and subsurface material, water in the subsurface, physical properties of the soil, search for an hypothesized microbial activity, characterization of radio-electric properties of the Martian ionosphere. Scientists at the origin of the present paper, already involved at a high degree of responsibility in several Mars missions, and actively preparing in situ instrumentation for future landed platforms (Netlander--now cancelled, MSL-09), express their readiness to participate in both ESA/AURORA and NASA programs of Mars human exploration. They think that the formation of a Mars Environment working group at ESA, in the course of the AURORA definition phase, could act positively in favour of the program, by increasing its scientific cross-section and making it still more focused on human exploration.

通过平均影响值（MIV）影响因子权重分析算法,以碳钢Q235、Ste355、St12和Q450腐蚀速率的暴露时间、气候因素和环境因素数据为依据,以|MIV|值为评价依据,定量分析15种影响因子（暴露时间、平均温度、平均相对湿度、日照时数、降水量、平均风速、海盐粒子浓度、SO₂、HCl、NO₂、H₂S、硫酸盐化速率、NH₃、降尘量-非水溶性、降尘量-水溶性）对碳钢腐蚀速率影响的权重大小。结果表明: 当MIV调节率从5%逐步递增至25%时,同种影响因子对腐蚀速率的影响权重变化不大,但4种碳钢对各影响因子的敏感度略有不同;气候因素对腐蚀速率影响最大,其次为暴露时间,环境因素中SO₂和降尘量对腐蚀速率影响较大;平均相对湿度、日照时数、平均温度是影响腐蚀速率最主要的3个因子。      

Corona discharge of Titan's troposphere.

The atmosphere of Titan is constantly bombarded by galactic cosmic rays and Saturnian magnetospheric electrons causing the formation of free electrons and primary ions, which are then stabilized by ion cluster formation and charging of aerosols. These charged particles accumulate in drops in cloud regions of the troposphere. Their abundance can substantially increase by friction, fragmentation or collisions during convective activity. Charge separation occurs with help of convection and gravitational settling leading to development of electric fields within the cloud and between the cloud and the ground. Neutralization of these charge particles leads to corona discharges which are characterized by low current densities. These electric discharges could induce a number of chemical reactions in the troposphere and hence it is of interest to explore such effects. We have therefore, experimentally studied the corona discharge of a simulated Titan's atmosphere (10% methane and 2% argon in nitrogen) at 500 Torr and 298 K by GC-FTIR-MS techniques. The main products have been identified as hydrocarbons (ethane, ethyne, ethene, propane, propene + propyne, cyclopropane, butane, 2-methylpropane, 2-methylpropene, n-butene, 2-butene, 2,2-dimethylpropane, 2-methylbutane, 2-methylbutene, n-pentane, 2,2-dimethylbutane, 2-methylpentane, 3-methylpentane, n-hexane, 2,2-dimethylhexane, 2,2-dimethylpentane, 2,2,3-trimethylbutane, 2,3-dimethylpentane and n-heptane), nitriles (hydrogen cyanide, cyanogen, ethanenitrile, propanenitrile, 2-methylpropanenitrile and butanenitrile) and an uncharacterized film deposit. We present their trends of formation as a function of discharge time in an ample interval and have derived their initial yields of formation. These results clearly demonstrate that a complex organic chemistry can be initiated by corona processes in the lower atmosphere. Although photochemistry and charged particle chemistry occurring in the stratosphere can account for many of the observed hydrocarbon species in Titan, the predicted abundance of ethene is to low by a factor of 10 to 40. While some ethene will be produced by charged-particle chemistry, its production by corona processes and subsequent diffusion into the stratosphere appears to be an adequate source. Because little UV penetrates to the lower atmosphere to destroy the molecules formed there, the corona-produced species may be long-lived and contribute significantly to the composition of the lower atmosphere and surface.
