    NASA has announced seven carefully-selected instruments that will make up the payload of the next rover being sent to Mars. The Mars 2020 rover is based on the successful design of Curiosity, which is currently exploring the martian surface. The new rover’s payload consists of upgraded hardware and new instruments that will study geology and the potential habitability of the martian environment, and will directly search for signs of ancient martian life.

    The selected payload proposals are:

    - Mastcam-Z, an advanced camera system with panoramic and stereoscopic imaging capability with the ability to zoom. The instrument also will determine mineralogy of the Martian surface and assist with rover operations. The principal investigator is James Bell, Arizona State University in Tempe.

    - SuperCam, an instrument that can provide imaging, chemical composition analysis, and mineralogy. The instrument will also be able to detect the presence of organic compounds in rocks and regolith from a distance. The principal investigator is Roger Wiens, Los Alamos National Laboratory, Los Alamos, New Mexico. This instrument also has a significant contribution from the Centre National d’Etudes Spatiales,Institut de Recherche en Astrophysique et Plane’tologie (CNES/IRAP) France.

    - Planetary Instrument for X-ray Lithochemistry (PIXL), an X-ray fluorescence spectrometer that will also contain an imager with high resolution to determine the fine scale elemental composition of Martian surface materials. PIXL will provide capabilities that permit more detailed detection and analysis of chemical elements than ever before. The principal investigator is Abigail Allwood, NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.

    - Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals (SHERLOC), a spectrometer that will provide fine-scale imaging and uses an ultraviolet (UV) laser to determine fine-scale mineralogy and detect organic compounds. SHERLOC will be the first UV Raman spectrometer to fly to the surface of Mars and will provide complementary measurements with other instruments in the payload. The principal investigator is Luther Beegle, JPL.

    - The Mars Oxygen ISRU Experiment (MOXIE), an exploration technology investigation that will produce oxygen from Martian atmospheric carbon dioxide. The principal investigator is Michael Hecht, Massachusetts Institute of Technology, Cambridge, Massachusetts.

    - Mars Environmental Dynamics Analyzer (MEDA), a set of sensors that will provide measurements of temperature, wind speed and direction, pressure, relative humidity and dust size and shape. The principal investigator is Jose Rodriguez-Manfredi, Centro de Astrobiologia, Instituto Nacional de Tecnica Aeroespacial, Spain.

    - The Radar Imager for Mars’ Subsurface Exploration (RIMFAX), a ground-penetrating radar that will provide centimeter-scale resolution of the geologic structure of the subsurface. The principal investigator is Svein-Erik Hamran, Forsvarets Forskning Institute, Norway.


    Finding Alien Life: On Earth, on Mars, and Throughout the Cosmos

    How do we define “life?” This fundamental question has remained largely philosophical, because it has been asked for so long, by so many, and with so few concrete conclusions.

    In this seminar, produced by the NASA Astrobiology Institute, Dr. Steven Benner takes a different tack. He shows how laboratory studies can create a second example of life, helping us develop a firmer scientific understanding of what life is. The challenge of “synthetic biology” is on!

    Dr. Benner discusses how we are hitchhiking on rockets, rovers, and telescopes to find life elsewhere in the Solar System, and describes how his research team is working to develop that second example of life in laboratories here on Earth, one step at a time.

    Nigel Goldenfeld: We Need a Theory of Life

    In this fascinating interview, the Huffington Post’s Suzan Mazur talks with NAI Principal Investigator Nigel Goldenfeld, of the University of Illinois, Urbana-Champaign. They discuss the emergence of a new theory of life, the nature of the evolutionary process, the origin of life, and more.

    “Our collaborative position was that the Modern Synthesis is simply not enough,” said Goldenfeld, “population genetics is not a full account of the evolution process because it manifestly does not describe evolution before genes, it does not describe evolution before there were species and the lineages. The Modern Synthesis wasn’t designed to do so.

    Data Management in Astrobiology

    Data management and sharing are growing concerns for scientists and funding organizations throughout the world. Funding organizations are implementing requirements for data management plans, while scientists are establishing new infrastructures for data sharing. One of the difficulties is sharing data among a diverse set of research disciplines. Astrobiology is a unique community of researchers, containing over 110 different disciplines.

    In this new study, the results of a survey of data management practices among scientists involved in the astrobiology community, and the NASA Astrobiology Institute (NAI) in particular, are presented. The results of the survey show that the astrobiology community shares many of the same concerns for data sharing as other groups. The benefits of data sharing are acknowledged by many respondents, but barriers to data sharing remain, including lack of acknowledgement, citation, time, and institutional rewards. Overcoming technical, institutional, and social barriers to data sharing will be a challenge into the future.

    Astrobiologists from the United States and Germany have recorded the highest level of UV radiation from the Sun yet known at the Earth’s surface.

    You might expect the highest radiation levels of this type on Earth to be somewhere in Antarctica – underneath the hole in Earth’s ozone layer. This layer of Earth’s stratosphere contains higher concentrations of ozone gas (O3) than the rest of the atmosphere, and it protects life on Earth by absorbing harmful UV radiation from the Sun. In the southern hemisphere above Antarctica, when the ozone develops, the ozone layer is at its thinnest and more UV radiation gets through to pummel to the surface.

    What astronomers thought were a pair of potentially life-friendly alien worlds are illusions, apparitions conjured up by a star’s intense magnetic activity, a new NAI-funded study suggests.

    These new findings could one day not only help astronomers dispel more such illusory exoplanets, but discover worlds that would otherwise remain hidden. A new video about the possible cosmic illusions also details the finding.

    The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.

    In a new study co-funded by the NAI, scientists compared three-dimensional structures of ribosomes from a variety of species of varying biological complexity, including humans, yeast, bacteria and archaea. The team found distinct “fingerprints” in the ribosomes where new structures were added to the ribosomal surface without altering the pre-existing ribosomal core, which originated over 3 billion years ago before the last universal common ancestor (LUCA) of life.

    Lewis and Clark and Early Career Collaboration Awardee, Roy Price first heard about the hydrothermal vents in New Caledonia’s Bay of Prony a decade ago. Being a scuba diver and a geologist, he was fascinated by the pictures of a 38-meter-high calcite “chimney” that had precipitated out of the highly-alkaline vent fluid.

    His attraction to this South Pacific site intensified over the years, as it was later revealed that the geochemistry of the hydrothermal fluids discharging in the Bay of Prony resemble that of the mid-Atlantic’s “Lost City,” one of the most spectacular of all hydrothermal vent systems. The unique chemical and biological conditions at the Lost City has led some scientists to speculate that the origin of life may have occurred around similar sorts of vents in the Earth’s distant past.

    Sugars of the Interstellar Medium…in the Lab

    Sugars of extraterrestrial origin have been observed in the interstellar medium (ISM), in at least one comet spectrum, and in several meteorites that have been recovered from the surface of the Earth. The origins of the sugars within the meteorites have been debated.

    To explore the possibility that sugars could be generated during shock events, a new study funded by the NASA Astrobiology Institute is the first set of laboratory impact experiments wherein glycolaldehyde, found in the ISM, as well as glycolaldehyde mixed with montmorillonite clay, have been subjected to reverberated shocks.

    New biologically-relevant molecules, including threose, erythrose and ethylene glycol, were identified in the resulting samples. These results show that sugar molecules can not only survive, but also become more complex, during impact delivery to planetary bodies.

    Workshop for Early-Career Geoscientists on the Process of Preparing and Publishing Papers

    On October 18, the day before GSA 2014 begins, this workshop, led by science editors from GSA’s journals, will focus on the process of preparing your research for submission to scholarly journals. Presentations by the three editors will be followed by roundtable discussions and a question-and-answer period.

    Before You Begin: You have a big pile of data and lots of good ideas. How do you parse all that into discrete, coherent papers? Knowing how to frame and structure your work for publication is fundamental. Find out what editors and reviewers look for, such as whether the paper fits the scope of the journal to which it was submitted, and whether the stated aims of the paper match the results and interpretations reported.

    Writing and Revising: The aim of this workshop isn’t to address the writing process itself, but to focus on the bigger creative picture. How do you frame your paper to meet the journal’s aims and the reviewers’ expectations? Find out what makes a well-prepared manuscript, from an attention-getting cover letter to an introduction that serves its purpose to well-thought-out figures and tables that communicate your ideas.

    • Get advice on what to include, what to leave out, and how best to structure your manuscript.
    • Learn how to avoid frustrating your paper’s reviewers.
    • Then learn how to submit your paper online and what to expect during the review and publication process.

    Reviewing: Be a Part of the Scholarly Community: Peer review is integral to publishing, so both reviewing and being reviewed are essential parts of your role as a scientist. As an early-career author, what kind of criticism should you expect and how should you respond to critical reviews? Reviewing the work of others is also a great way to discover what works in a paper and what does not, and it teaches you the things to avoid in your own writing. Hear from the experts on what constitutes a good review and how you benefit from being a reviewer.

    Apply to Attend: Space is free but limited for this workshop. It will take place at the GSA Vancouver, BC venue from 8:30 – 11:00am. Please e-mail editing@geosociety.org for an application. We welcome applications from graduate students, early-career researchers, people getting back into research after a hiatus, post-docs, or anyone for whom this discussion is relevant.
