    Amino Acids and the Asymmetry of Life Advances in Astrobiology and Biogeophysics springer.com This series aims to report new developments in research and teaching in the inter- disciplinary fields of astrobiology and biogeophysics. This encompasses all aspects of research into the origins of life – from the creation of matter to the emergence of complex life forms – and the study of both structure and evolution of planetary ecosystems under a given set of astro- and geophysical parameters. The methods con- sidered can be of theoretical, computational, experimental and observational nature. Preference will be given to proposals where the manuscript puts particular emphasis on the overall readability in view of the broad spectrum of scientific backgrounds involved in astrobiology and biogeophysics. The type of material considered for publication includes: • Topical monographs • Lectures on a new field, or presenting a new angle on a classical field • Suitably edited research reports • Compilations of selected papers from meetings that are devoted to specific topics The timeliness of a manuscript is more important than its form which may be un- finished or tentative. Publication in this new series is thus intended as a service to the international scientific community in that the publisher, Springer-Verlag, offers global promotion and distribution of documents which otherwise have a restricted readership. Once published and copyrighted, they can be documented in the scientific literature. Series Editors: Dr. André Brack Dr. Christopher P.

Received: 22 February 2019; Accepted: 11 March 2019; Published: 16 March 2019 Abstract: The biomolecular homochirality in living organisms has been investigated for decades, but its origin remains poorly understood. It has been shown that circular polarized light (CPL) and other energy sources are capable of inducing small enantiomeric excesses (ees) in some primary biomolecules, such as amino acids or sugars. Since the first findings of amino acids in carbonaceous meteorites, a scenario in which essential chiral biomolecules originate in space and are delivered by celestial bodies has arisen. Numerous studies have thus focused on their detection, identification, and enantiomeric excess calculations in extraterrestrial matrices. In this review we summarize the discoveries in amino acids, sugars, and organophosphorus compounds in meteorites, comets, and laboratory-simulated interstellar ices.

  • Rosetta/COSAC
    C4PO research themes 10.1 ESA’s Cometary Mission Rosetta-Philae A. Context and state of the art Uwe Meierhenrich, member of the Institut Convergence, is involved as Co-Investigator (Co-I) in the COSAC experiment of the Rosetta-Philae mission. He is in particular in charge of the chirality-part of COSAC: ESA’s Rosetta mission [1], successfully launched in March 2004, reached its target comet 67P/Churyumov- Gerasimenko (67P/C-G) in 2014. Contrary to its predecessor missions Giotto and Vega to comet 1P/Halley [2,3], Deep-Space 1 to comet 19P/Borrelly [4], Stardust to comet 81P/Wild 2 [5], and Deep Impact to comet 9P/Tempel 1 [6], Rosetta is the first space mission designed and constructed to follow a cometary nucleus through perihelion passage and to deposit a landing unit on the cometary nucleus. In November 2014 the Philae lander detached from the Rosetta spacecraft and landed on the surface of the cometary nucleus that was of unknown morphology and chemical composition. Philae contains the cometary sampling and composition (COSAC) instrument that is equipped with a chirality module for the in situ identification, separation, and quantification of organic molecules including enantiomers expected to be present in cometary ices. The COSAC analysis was assumed to provide essential information on the Solar System formation and possibly on the origin of organic molecules and molecular asymmetry in biological systems [7]. COSAC is equipped with a multi-column gas chromatograph (GC), a time-of-flight mass spectrometer (TOFMS), and connected to an electronic system that allows remote operation of the suite.

  • Artificial Comet Contains Building Blocks of Life 21 March 2012
    Artificial comet contains building blocks of life 21 March 2012 space mission 'Rosetta'. The program aims to place a lander on the comet Churyumov-Gerasimenko to study the composition of its nucleus. In a bid to anticipate Rosetta's findings, the scientists decided to create an artificial comet, or 'simulation of interstellar/cometary ice', and analyze its composition. The team led by Louis Le Sergeant d'Hendecourt was in charge of creating a micro-comet at the Institut d'Astrophysique Spatiale. Under extreme conditions similar to those found in space (-200 °C and in a vacuum), the researchers condensed a number of compounds found in the interstellar medium, such as water (H2O), ammonia (NH3) and methanol (CH3OH) molecules, onto a solid piece of Chromatogram of the cometary ice obtained using the magnesium fluoride (MgF2), while subjecting them multidimensional gas chromatograph.

  • Exomars/MOMA
    C4PO research themes 10.2 ESA’s Mission ExoMars 2016 and ExoMars 2018 A. Context and state of the art Uwe Meierhenrich, member of the Institut Convergence is involved as Co-Investigator (Co-I) in the MOMA experiment of the ExoMars 2018 mission: The Rosetta mission carried the first experiment ever sent outside Earth to investigate chirality, the COSAC experiment onboard the Rosetta Lander Philae. Meierhenrich is Co-I of the COSAC instrument and was in charge of its chirality part. In the context of planet Mars, it is important to investigate whether or not organic species including chiral organic molecules can be identified and quantified on its surface and/or subsurface. Martian organic molecules might be relicts of stellar evolution brought to Mars via meteorites, they might be remnants of chemical evolution on Mars itself, but also remains of extinct (or present-day) life on the Red Planet. In order to distinguish between these three potential pathways of formation, the chirality of Martian organic enantiomers would be of high importance to study. Officials from the European and North-American Space Agencies ESA and NASA understood this immense research opportunity to be of outstanding interest. As a consequence, NASA’s Mars Science Laboratory (MSL) payload of the Curiosity Rover has been equipped with a similar chirality module [1, 2]. The results of this module regarding the chirality of organics on Mars have not yet been reported. B. Current activity Driven by the importance to detect organic molecules on Mars, the European Space Agency ESA decided to design a mission to Mars ready to start in 2016.

Comets are thought to preserve the most pristine material currently present in the solar system, as they are formed by agglomeration of dust particles in the solar nebula, far from the Sun, and their interiors have remained cold. By approaching the Sun, volatile components and dust particles are released forming the cometary coma. During the phase of Heavy Bombardment, 3.8–4 billion years ago, cometary matter was delivered to the Early Earth. Precise knowledge on the physico-chemical composition of comets is crucial to understand the formation of the Solar System, the evolution of Earth and particularly the starting conditions for the origin of life on Earth. Here, we report on the COSAC instrument, part of the ESA cometary mission Rosetta, which is designed to characterize, identify, and quantify volatile cometary compounds, including larger organic molecules, by in situ measurements of surface and subsurface cometary samples. The technical concept of a multi-column enantio-selective gas chromatograph (GC) coupled to a linear reflectron time-of-flight mass-spectrometer instrument is presented together with its realisation under the scientific guidance of the Max-Planck-Institute for Solar System Research in Katlenburg-Lindau, Germany.
