    The Starting Materials In: Meteorites and the Early Solar System II S. Messenger Johnson Space Center S. Sandford Ames Research Center D. Brownlee University of Washington Combined information from observations of interstellar clouds and star forming regions and studies of primitive solar system materials give a first order picture of the starting materials for the solar system’s construction. At the earliest stages, the presolar dust cloud was comprised of stardust, refractory organic matter, ices, and simple gas phase molecules. The nature of the starting materials changed dramatically together with the evolving solar system. Increasing temperatures and densities in the disk drove molecular evolution to increasingly complex organic matter. High temperature processes in the inner nebula erased most traces of presolar materials, and some fraction of this material is likely to have been transported to the outermost, quiescent portions of the disk. Interplanetary dust particles thought to be samples of Kuiper Belt objects probably contain the least altered materials, but also contain significant amounts of solar system materials processed at high temperatures. These processed materials may have been transported from the inner, warmer portions of the disk early in the active accretion phase. 1. Introduction A principal constraint on the formation of the Solar System was the population of starting materials available for its construction. Information on what these starting materials may have been is largely derived from two approaches, namely (i) the examination of other nascent stellar systems and the dense cloud environments in which they form, and (ii) the study of minimally altered examples of these starting materials that have survived in ancient Solar System materials.

  • Asteroidal Dust 423
    Dermott et al.: Asteroidal Dust 423 Asteroidal Dust Stanley F. Dermott University of Florida Daniel D. Durda Southwest Research Institute Keith Grogan NASA Goddard Space Flight Center Thomas J. J. Kehoe University of Florida There is good evidence that the high-speed, porous, anhydrous chondritic interplanetary dust particles (IDPs) collected in Earth’s stratosphere originated from short-period comets. How- ever, by considering the structure of the solar-system dust bands discovered by IRAS, we are able to show that asteroidal collisions are probably the dominant source of particles in the zodiacal cloud. It follows that a significant and probably the dominant fraction of the IDPs collected in Earth’s stratosphere also originated from asteroids. IDPs are the most primitive particles in the inner solar system and represent a class of material quite different from that in our meteorite collections. The structure, mineralogy, and high C content of IDPs dictate that they cannot have originated from the grinding down of known meteorite types. We argue that the asteroidal IDPs were probably formed as a result of prolonged mechanical mixing in the deep regoliths of asteroidal rubble piles in the outer main belt. 1.

  • Urea, Glycolic Acid, and Glycerol in an Organic Residue Produced by Ultraviolet Irradiation of Interstellar=Pre-Cometary Ice Analogs
    ASTROBIOLOGY Volume 10, Number 2, 2010 ª Mary Ann Liebert, Inc. DOI: 10.1089=ast.2009.0358 Urea, Glycolic Acid, and Glycerol in an Organic Residue Produced by Ultraviolet Irradiation of Interstellar=Pre-Cometary Ice Analogs Michel Nuevo,1,2 Jan Hendrik Bredeho¨ft,3 Uwe J. Meierhenrich,4 Louis d’Hendecourt,1 and Wolfram H.-P. Thiemann3 Abstract More than 50 stable organic molecules have been detected in the interstellar medium (ISM), from ground-based and onboard-satellite astronomical observations, in the gas and solid phases. Some of these organics may be prebiotic compounds that were delivered to early Earth by comets and meteorites and may have triggered the first chemical reactions involved in the origin of life. Ultraviolet irradiation of ices simulating photoprocesses of cold solid matter in astrophysical environments have shown that photochemistry can lead to the formation of amino acids and related compounds. In this work, we experimentally searched for other organic molecules of prebiotic interest, namely, oxidized acid labile compounds. In a setup that simulates conditions relevant to the ISM and Solar System icy bodies such as comets, a condensed CH3OH:NH3 ¼ 1:1 ice mixture was UV irradiated at *80 K. The molecular constituents of the nonvolatile organic residue that remained at room temperature were separated by capillary gas chromatography and identified by mass spectrometry. Urea, glycolic acid, and glycerol were detected in this residue, as well as hydroxyacetamide, glycerolic acid, and glycerol amide. These organics are interesting target molecules to be searched for in space. Finally, tentative mechanisms of formation for these compounds under interstellar=pre-cometary conditions are proposed.

Usatov1 Report, Planetary Sciences Unit (AST80015), Swinburne Astronomy Online ABSTRACT Geomorphological, mineralogical and other evidence of the conditions favoring the existence of water on Mars in liquid phase is reviewed. This includes signatures of past and, possibly, present aqueous environments, such as the northern ocean, lacustrine environments, sedimentary and thermokarst landforms, glacial activity and water erosion features. Reviewed also are hydrous weathering processes, observed on surface remotely and also via analysis of Martian meteorites. Chemistry of Martian water is discussed: the triple point, salts and brines, as well as undercooled liquid interfacial and solid-state greenhouse effect melted waters that may still be present on Mars. Current understanding of the evolution of Martian hydrosphere over geological timescales is presented from early period to the present time, along with the discussion of alternative interpretations and possibilities of dry and wet Mars extremes. 1.

  • The Planet Earth-I)
    Geology (The Planet Earth-I) UNIT-1 The Planet Earth-I 1. ORIGIN OF THE SOLAR SYSTEM AND EARTH The Solar System The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas. Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is, the more gravity it has. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it. At the same time, these objects, which are moving very rapidly, try to fly away from the Sun, outward into the emptiness of outer space. The result of the planets trying to fly away, at the same time that the Sun is trying to pull them inward is that they become trapped half-way in between. Balanced between flying towards the Sun, and escaping into space, they spend eternity orbiting around their parent star. Our solar system consists of an average star we call the Sun, the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. It includes: the satellites of the planets; numerous comets, asteroids, and meteoroids; and the interplanetary medium. The Sun is the richest source of electromagnetic energy (mostly in the form of heat and light) in the solar system. The Sun's nearest known stellar neighbor is a red dwarf star called Proxima Centaury, at a distance of 4.3 light years away.

  • "THE GENERAL THEORY of META-DYNAMICS SYSTEMICITY" Part Four: Early Earth and Origin of Life’S Metadynamics Systemicity
    "THE GENERAL THEORY OF META-DYNAMICS SYSTEMICITY" Part four: Early Earth and origin of Life’s metadynamics systemicity Jean-Jacques BLANC Consulting Engineer Crets de Champel, 9 CH - 1206 – Geneva, Switzerland Tel/fax: +41(22)346 30 48 E-mail: [email protected] Url: www.bioethismscience.org The "Cosmo-planetary and terrestrial meta-dynamics systemicity”, the “Life’s meta-dynamics systemicity”, and "Biological meta-dynamics systemicity" are the core of a general theory resulting from a “Bioethism transdisciplinary approach” of the whole set of dynamics that made and sustains Life as to exist throughout the atomic and molecular universal cycles systemicity. Part four of this theory describes the Universe Cosmo-planetary metadynamics as having participated in the Sun system and its planets to form, particularly the Earth at the right “habitable zone”. The physicochemical environmental conditions of this site became propitious for Life to “hatch” within biochemical thermodynamics1 and evolution development metadynamics. ABSTRACT Ever since 1996, J.-J. Blanc, the author of this theory, made an extensive research on "Systems science" that induced to his developing a new systemic2 paradigm in terms of a transdisciplinary approach to "Living systems" that he named “The Bioethism” (see note 3). The transdisciplinary approach is meant to support the acquisition of a large understanding of living systems' origin, of their natural structure and their adaptive behaviors. Their specific bonds and traits, as well as their evolution trends, while permanently interacting with environmental events for survival4, require actions-reactions from ago-antagonistic signals and stimuli. Endogenous within their body milieu and exogenous, these signals and stimuli are adapting with conditions of ecosystemic and sociosystemic environments.

The symposium brought together more than 200 scientists from the U. S. and Europe to discuss the importance of exploring the inter- planetary medium, and viewing the Sun over a wide range of heliographic latitudes. Among the topics discussed were the missions that NASA and ESA are currently considering for possible flight out of the ecliptic plane, and the likely scientific returns of these missions in the areas of solar, interplanetary and cosmic-ray physics. The symposium was sponsored by NASA and ESA, and was a topical meeting of the American Astronomical Society and the American Geophysical Union.

  • Climatic Processes and Agriculture B
    UDC 551.12:620.96 © 2015 Climatic processes and agriculture B. Panasiuk, Academician of the NAAS, Doctor of Economic Sciences Institute of Bioenergetic Crops and Sugar Beet of the NAAS The purpose. To study and justify dependence of agriculture on new climatic processes on an instance of separate components, in particular dynamics of soil moisture and saturation with carbon dioxide (СО2). Methods. Analytical, statistical, generalizing philosophical-scientific understanding of nature of wildlife and climate; dependence of photosynthesis on natural instability of climatic processes, humanitarian-scientific understanding of sunspace energy. Results. It is proved that in modern conditions, together with rainfall and temperature of air, growth of cultivated plants is considerably depends on carbon dioxide (СО2) and soil moisture. Conclusions. To determine perspectives of further development of agriculture it is necessary to use in an index of hydrothermal quotient (HTQ) parameters of long-term daily average rainfall and temperatures of air, parameters of humidity of soils and level of concentration of carbon dioxide (СО2) which are expedient for fixing in the certain terrain. Key words: photosynthesis, soil moisture, carbon dioxide (СО2), rainfall, temperature of air, hydrothermal quotient, crops. Modern geological science claims that plants as representatives of living matter first appeared in the water, forming oxygen and the ozone layer. Subsequently, on the land began to form a modern plant and animal world, this process continues to this day. Often the question arises: Is it really that, having originated 3.8 billion years ago in the form of the simplest unicellular bacteria, has life been formed for so long from simple to complex? After all, on the planet Earth complicated, sometimes terrible geological processes occurred, the planet changed from one orbit to another, the climate changed many times.

  • Particles and Fields in the Interplanetary Medium M
    PARTICLES AND FIELDS IN THE INTERPLANETARY MEDIUM By KENNETH G. -MCCRACKEN UNIVERSITY OF ADELAIDE, ADELAIDE, AUSTRALIA M\Ian's knowledge of the properties of interplanetary space has advanced radically since 1962, the major part of this advance occurring since the commencement of the International Years of the Quiet Sun. The IQSY has, in fact, been quite unique in that it has seen the augmentation of the extensive synoptic studies of both geo- physical and solar phenomena such as were mounted during the IGY and its predecessors, the Polar Years of 1882 and 1932, by essentially continuous in situ studies of the interplanetary medium by detectors flown on interplanetary space- craft. Thus, since late 1963, no less than ten interplanetary spacecraft belonging to the Interplanetary -Monitoring Platform (DIP), Eccentric Geophysical Observa- tory (EGO), -Mariner, Pioneer, and Zond series have provided almost continuous surveillance of interplanetary phenomena, using second- and third-genleration detection devices. The fact that most of these spacecraft have made simultaneous measurements of a nIumber of the properties of the interplanetary medium has provided detailed information on the causal relationships between the several interplanetary parameters and geophysical phenomena, at a tinme when the relative lack of solar activity resulted in an attractive simplicity in the observed data. As' a consequence, the IQSY has provided an unprecedented series of observations of the causal relationships between solar, interplanetary, and geophysical phenomena, which will be of major importance in understanding the more complicated situations observed during periods of appreciable solar activity. In this review, I attempt to summarize the 1967 understanding of the interplanetary medium, this under- standing being based very heavily on work performed during and since the IQSY.
