Publication Date 2007-07-01 Peer reviewed eScholarship.org Powered by the California Digital Library University of California Meteoritics & Planetary Science 42, Nr 7/8, 1045–1054 (2007) Abstract available online at http://meteoritics.org Ernst Zinner, lithic astronomer Kevin D. MCKEEGAN Department of Earth and Space Sciences, University of California, Los Angeles, Los Angeles, California 90095–1567, USA E-mail: [email protected] It is a rare privilege to be one of the founders of an entirely new field of science, and it is especially remarkable when that new field belongs to the oldest branch of “natural philosophy.” The nature of the stars has perplexed and fascinated humanity for millennia. While the sources of their luminosity and their structures and evolution were revealed over the last century, it is thanks to the pioneering efforts of a rare and remarkable man, Ernst Zinner, as well as his colleagues and students (mostly at the University of Chicago and at Washington University in Saint Louis), that in the last two decades it has become possible to literally hold a piece of a star in one’s hand. Armed with sophisticated microscopes and mass spectrometers of various sorts, these “lithic astronomers” are able to reveal stellar processes in exquisite detail by examining the chemical, mineralogical, and especially the nuclear properties of these microscopic grains of stardust. With this special issue of Meteoritics & Planetary Science, we honor Ernst Zinner (Fig. -
Meteorites and Impacts: Research, Cataloguing and Geoethics
Seminario_10_2013_d 10/6/13 17:12 Página 75 Meteorites and impacts: research, cataloguing and geoethics / Jesús Martínez-Frías Centro de Astrobiología, CSIC-INTA, asociado al NASA Astrobiology Institute, Ctra de Ajalvir, km. 4, 28850 Torrejón de Ardoz, Madrid, Spain Abstract Meteorites are basically fragments from asteroids, moons and planets which travel trough space and crash on earth surface or other planetary body. Meteorites and their impact events are two topics of research which are scientifically linked. Spain does not have a strong scientific tradition of the study of meteorites, unlike many other European countries. This contribution provides a synthetic overview about three crucial aspects related to this subject: research, cataloging and geoethics. At present, there are more than 20,000 meteorite falls, many of them collected after 1969. The Meteoritical Bulletin comprises 39 meteoritic records for Spain. The necessity of con- sidering appropriate protocols, scientific integrity issues and a code of good practice regarding the study of the abiotic world, also including meteorites, is emphasized. Resumen Los meteoritos son, básicamente, fragmentos procedentes de los asteroides, la Luna y Marte que chocan contra la superficie de la Tierra o de otro cuerpo planetario. Su estudio está ligado científicamente a la investigación de sus eventos de impacto. España no cuenta con una fuerte tradición científica sobre estos temas, al menos con el mismo nivel de desarrollo que otros paí- ses europeos. En esta contribución se realiza una revisión sintética de tres aspectos cruciales relacionados con los meteoritos: su investigación, catalogación y geoética. Hasta el momento se han reconocido más de 20.000 caídas meteoríticas, muchas de ellos desde 1969. -

The discovery catalyzed a range of studies in physics to develop an understanding of the nucleus and the properties influencing its stability and instability that give rise to various decay modes and associated energies. Rutherford and Soddy (1903) later suggested that radioactive change from different types of decay are linked to chemical change. Soddy later found that this is a general phenomenon and radioactive decay of different energies and types are linked to the same element. Soddy (1913) in his paper on intra-atomic charge pinpointed the observations as requiring the observations of the simultaneous character of chemical change from the same position in the periodic chart with radiative emissions required it to be of the same element (same proton number) but differing atomic weight. This is only energetically accommodated by a change in neutrons and it was this paper that the name “isotope” emerges. -

1968 Oct 8-10 Council Minutes
Minutes of the Council Meeting of the Meteoritical Society October 8, 1968 Hoffman Geological Laboratory Harvard University Cambridge The meeting was convened at 2:15 p.m. with President Carleton B. Moore presiding. In attendance were Vice Presidents Barandon Barringer, Robert S. Dietz and John A. O'Keefe, Secretary Roy S. Clarke, Jr., Treasurer Ursula B. Marvin, Editor Dorrit Hoffleit, Past President Peter M. Millman, and Councilors Richard Barringer, Kurt Fredriksson, Gerald S. Hawkins, Klaus Keil, Brian H. Mason and John A. Wood. Robin Brett, John T. Wasson and Fred L. Whipple attended the meeting as visitors. Minutes The minutes of the Council meeting held at the Holiday Inn, Mountain View California, on October 24, 1967, were approved as submitted. Program, 31st Annual Meeting Ursula Marvin presented the program for the Annual Meeting and discussed arrangements and last minute changes. The Council unanimously approved the program as presented and thanked Mrs. Marvin and her coworkers for their efforts on behalf of the Society. Secretary's Report The report of the Secretary was submitted to the Council in writing and was accepted as submitted (copy attached). There was brief discussion of the nomenclature problem of Barringer Meteor Crater. It was pointed out that in the final analysis usage determines the name that becomes accepted. It was suggested that Society members use the name Barringer Meteor Crater in speaking and writing and that we encourage others to do the same. No other action was suggested at this time. The problem of dues for foreign members was discussed, and several individuals suggested that funds are available to help in cases of demonstrated need. -

SUPPLEMENT TO METEORITICS & PLANETARY SCIENCE, VOL. 36, 11 The Meteoritical Society Newsletter (November 2001) A report of the business carried out by the Society over the past year, edited by Edward Scott, Secretary. PRESIDENT'S EDITORIAL Nomenclature President's Editorial Gero Kurat There are some indications that SNC meteorites could originate from Mars, there are others that relate them to carbonaceous Things usually turn out somewhat different from what one expects chondrites. Among the advocates for a martian origin is also the them to be and this was exactly so also with my first few months in foremost expert on these meteorites, Hap McSween. Some colleagues office. I was positively surprised by the amount of activities initiated neglect the possibility that SNC meteorites could not come from Mars by members of our Society. The overwhelmingly constructive and call them "martian meteorites". Others prefer to call them contributions make investing time for the Society a joy. There are, "SNICs", for obvious reasons. Hap has this year been honored for however, also some unsolved problems which do not create instant his work on "martian meteorites". As the possibility for a non-martian joy but whose solution eventually could lead to improvements origin of SNC meteorites still exists, a curious conundrum emerges: beneficial for all of us. So joy is awaiting us afterwards. Us means how could Hap have done this wonderful work on something that the Council and in particular the Secretary of the Society who does possibly does not exist? Please help us to solve that riddle—the best an excellent job in spite of the bumpy communication between our three solutions will receive prizes. -

One of the goals of these networks is to provide the necessary information Revised 6 April 2018 for linking meteorites to their pre-impact, heliocentric orbits and ultimately to their source regions in the Accepted 13 April 2018 solar system. We re-compute heliocentric orbits for the 25 meteorite falls published to date from original Available online 14 April 2018 data sources. Using these orbits, we constrain their most likely escape routes from the main asteroid belt Keywords: and the cometary region by utilizing a state-of-the-art orbit model of the near-Earth-object population, Meteorites which includes a size-dependence in delivery efficiency. While we find that our general results for escape Meteors routes are comparable to previous work, the role of trajectory measurement uncertainty in escape-route Asteroids identification is explored for the first time. -

Goldstein To tell the truth, I was a bit bewildered when I was assigned the task of giving the citation for Joe Goldstein for the Leonard Medal. Who was this guy? We had never worked in the same research group and had never published a paper together. I thought I had occasionally seen him in Houston at the Lunar and Planetary Science Conference, but never after Wednesday. I asked one of the postdocs in our group at UCLA who Goldstein was, but he had no idea. Now it began to make sense. Goldstein was just another Leonard medallist no one had ever heard of. I reasoned that he must be some Meteoritical Society apparatchik working his way through the ranks. This suspicion was confirmed when I found out that he is a former treasurer of the society and currently its vice- president—a man obviously being groomed for the top spot. So, to complete my assignment, I did what any modern investigator would do. -

Drake It's been another great year for the Meteoritical Society! Mini Wadhwa, Andy Davis, and colleagues did a wonderful job of organizing and running the Chicago meeting and associated functions. Chicago was revealed as a vibrant, elegant city. As always, there are special people and families who provide generous help to the Society. The Barringer family has continued its support of graduate student travel, the Barringer Medal, and the Barringer lecture, which was given by Torrence Johnson. The Society is extremely grateful for this generous support. Speaking of medals, this year's medallists were Guenter Lugmair (Leonard Medal), Ralph Baldwin (Barringer Medal), and Meenakshi Wadhwa (Nier Prize - and chocolate medallions!) Congratulations to Guenter, Ralph, and Mini! In Rome, the awardees will be Harry McSween (Leonard Medal), Sasha Basilevsky (Barringer Medal), and Larry Nittler (Nier Prize), again well-deserved recipients of our prestigious awards. There will be further changes in Officers of the Society. It is my great pleasure to announce that Gero Kurat assumes the office of President, Gary Huss Vice President, and Tim Swindle Treasurer of the Meteoritical Society. David Kring has graciously agreed to serve as Deputy Treasurer. As you are aware, this year was the first since the 1970s that we had a contested Presidential election.
