The nights are colder than Antarctica has ever been, and even summer days are freezing. The atmosphere is so thin, that it would boil our blood from the smallest wound, and the air consists of deadly amounts of carbon dioxide. There is no life, there is no running water and there is no shelter to escape the Sun’s ultra- violet radiation that sterilizes everything left to the Red Planet’s surface.

INTRODUCTION a surrounding solid ice shell on Saturn's moon Enceladus. Images The Vaporizing Ice Penetration Experiment on a Rocket of Enceladus' South Pole showed several fissures in the ice shell (VIPER) is a REXUS-Experiment to collect scientific data with plumes constantly exhausting frozen water particles, while melting probes penetrate samples of water ice in low building up the E-Ring, one of the outer rings of Saturn. In this temperature, low gravity and low ambient pressure on a southern region of Enceladus, the ice shell is considered to be as thin as 2 km, about an order of magnitude thinner than on the sounding rocket. It is managed and realized as a student project rest of the moon. Under the ice shell, there is a global ocean at FH Aachen University of Applied Sciences (FH Aachen consisting of liquid water. Scientists are discussing different UAS). In total, around 15 students from FH Aachen UAS and approaches the possibilities of taking samples of water, i.e. by RWTH Aachen University are working voluntarily at VIPER melting through the ice using a melting probe.

  • Introducción
    Annual Report CAB 2018 INTRODUCCIÓN El Centro de Astrobiología (CAB) se fundó en 1999 como un Centro Mixto entre el Consejo Superior de Investigaciones Científicas (CSIC) y el Instituto Nacional de Técnica Aeroespacial (INTA). Localizado en el campus del INTA en Torrejón de Ardoz (Madrid), el CAB se convirtió en el primer centro fuera de los Estados Unidos asociado al recién creado NASA Astrobiology Institute (NAI), convirtiéndose en miembro formal en el año 2000. La Astrobiología considera la vida como una consecuencia natural de la evolución del Universo, y en el CAB trabajamos para estudiar el origen, evolución, distribución y futuro de la vida en el Universo, tanto en la Tierra como en entornos extraterrestres. La aplicación del método científico a la Astrobiología requiere la combinación de teoría, simulación, observación y experimentación. Esta aplicación de la Ciencia fundamental a las cuestiones de la Astrobiología es el principal objetivo del CAB. La organización multi- y transdiciplinar del Centro fomenta la interacción de los ingenieros con investigadores experimentales, teóricos y observacionales de varios campos: astronomía, geología, bioquímica, biología, genética, teledetección, ecología microbiana, ciencias de la computación, física, robótica e ingeniería de las comunicaciones. La investigación en el CAB aborda la sistematización de la cadena de eventos que tuvieron lugar entre el Big Bang inicial y el origen de la vida, incluyendo la autoorganización del gas interestelar en moléculas complejas y la formación de sistemas planetarios con ambientes benignos para el florecimiento de la vida. El objetivo final es investigar la posible existencia de vida en otros mundos, reconociendo biosferas diferentes de la terrestre, para ayudarnos en la comprensión del origen de la vida.

    Life 2012, 2, 1-105; doi:10.3390/life2010001 OPEN ACCESS life ISSN 2075-1729 www.mdpi.com/journal/life Article Theory of the Origin, Evolution, and Nature of Life Erik D. Andrulis Department of Molecular Biology and Microbiology, Case Western Reserve University School of Medicine, Wood Building, W212, Cleveland, OH 44106, USA; E-Mail: [email protected]; Tel.: +1-216-368-0261; Fax: +1-216-368-3055 Received: 15 November 2011; in revised form: 10 December 2011 / Accepted: 13 December 2011 / Published: 23 December 2011 Abstract: Life is an inordinately complex unsolved puzzle. Despite significant theoretical progress, experimental anomalies, paradoxes, and enigmas have revealed paradigmatic limitations. Thus, the advancement of scientific understanding requires new models that resolve fundamental problems. Here, I present a theoretical framework that economically fits evidence accumulated from examinations of life. This theory is based upon a straightforward and non-mathematical core model and proposes unique yet empirically consistent explanations for major phenomena including, but not limited to, quantum gravity, phase transitions of water, why living systems are predominantly CHNOPS (carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur), homochirality of sugars and amino acids, homeoviscous adaptation, triplet code, and DNA mutations. The theoretical framework unifies the macrocosmic and microcosmic realms, validates predicted laws of nature, and solves the puzzle of the origin and evolution of cellular life in the universe. Keywords: quantum; gyre; emergence; thermodynamics; singularity; natural law; adaptation; learning and memory 1. Introduction How life abides by the second law of thermodynamics yet evolutionarily complexifies and maintains its intrinsic order is a fundamental mystery in physics, chemistry, and biology [1].

Space mining can solve those problems, but, first, wide geological surveying space missions using drilling methods are necessary. Additionally, drilling methods will be important in geological, life searching, geoengineering, and many other studies of extraterrestrial objects. Space is becoming a new area of possible drilling applications. Designing future space drilling missions requires adapting drilling technologies, not only to the conditions of the space environment, but also to the economic and technological realities of the space industry. The possibility of constructing low mass coring devices with energy consumption below 100 W was investigated in this paper. Minimization of energy consumption and mass of a coring is essential for the device to be used in space missions, when lander instruments supplied by low power electric battery are expected to work reliably and Citation: Zwierzy´nski,A.J.; Teper, the launch cost (depending of mass) at an economically acceptable level.
