Dating Impact Craters: What Can Precise and Accurate Ages Teach Us? (Martin Schmieder),
Moved to Hess Room
Impacts have played a major role in the evolution of planetary bodies and asteroids in the Solar System. About 188 impact structures – large and small, old and young – are currently known on Earth. The improvements in isotopic dating methods, in addition to stratigraphic age constraints, now offer an increasingly precise and accurate set of age data for a number of impact events on our planet. In this seminar I will present a synthesis of recent findings, current challenges and open questions in terrestrial impact crater geochronology mainly based on the 40Ar/39Ar dating technique, with examples from the North American, European and Australian impact cratering record. Precise and accurate impact ages are crucial when it comes to the potential link between large meteorite impacts, mass extinctions and biodiversification events; evidence for binary asteroid impacts and multiple impact events in the geologic record; and the nature and longevity of hydrothermal activity in cooling impact craters as hosts for economic deposits and niches for microbial life. |

Preservation of Isotopic Heterogeneity in a Convecting Martian Mantle (Walter Kiefer, Lunar and Planetary Institute),
Lecture Hall
The existence of volcanic activity on Mars in the last 200 million years is demonstrated by both the low crater densities on volcanos such as Olympus Mons and by radiometric dating of the shergottite meteorites. This implies the existence of adiabatic decompression melting and thus an actively convecting mantle. On the other hand, the preservation of isotopically distinct reservoirs that formed in the first 100 million years of solar system history has been interpreted by some investigators as evidence that the martian mantle cannot be convecting. This apparent paradox can be resolved by considering the effects of geographic isolation of isotopic reservoirs and of inefficient convective mixing, which together allow geochemical reservoirs to be preserved within a convecting martian mantle. |

Workshop on Planetary Protection Knowledge Gaps for Human Extraterrestrial Meetings *,
Moffett Field, California
While planetary protection requirements are in place for robotic missions, there is presently insufficient scientific and technological knowledge to establish effective quantitative requirements for the development of crewed spacecraft and missions. To prepare for such future missions, NASA created the NASA Policy on Planetary Protection Requirements for Human Extraterrestrial Missions (NPI 8020.7) that outlines the need to increase knowledge in the following study areas while iteratively developing an appropriate set of requirements: Study Area 1: Microbial and human health monitoring; Study Area 2: Technology and operations for contamination control; Study Area 3: Natural transport of contamination on Mars. The goal of this workshop is to capture the current state of knowledge in the aforementioned areas and identify additional research to appropriately inform planetary protection requirements development for the human exploration of Mars. |

Investigating early lunar evolution through U-Pb chronology of the Northwest Africa 773 Clan Meteorites (Barry Shaulis, University of Alberta),
Lecture Hall
The Northwest Africa (NWA) 773 clan of meteorites represent some of the youngest lunar igneous rocks discovered so far. We selected four members of the NWA 773 clan of meteorites for U-Pb zircon and baddeleyite age analysis: NWA 773, NWA 3170, NWA 6950, and NWA 7007. These meteorites were selected because: 1) Constraining the timing of igneous activity that produced these lunar rocks is critical to furthering our understanding of the thermal evolution of the Moon and evaluating potential heats sources responsible for igneous activity at least 1.5 Gyrs after lunar accretion; 2) Each of the meteorites is partially or wholly comprised of one or both of the magnesian or ferroan gabbro lithologies. This is crucial to further understanding of the proposed co-magmatic origin of the lithologies. 3) Several members contain merrillite or apatite in either a breccia or gabbro lithology. Merrillite and apatite are important uranium bearing minerals for dating and can therefore be used to establish an impact and/or brecciation history of the NWA 773 clan via U-Th-Pb dating methods. A total of 50 baddeleyite grains were analyzed and yielded weighted average 207Pb-206Pb ages of 3119.4 ± 9.4 Ma for the magnesian gabbro, 3106 ± 22 Ma for the ferroan gabbro, and 3115 ± 14 Ma for the polymict breccia. These data establish a strong chronologic link between the meteorites and indicate that the magnesian and ferroan gabbro lithologies formed at similar times. This implies that they are both temporally and petrogenetically related. A single large zircon grain found in the polymict breccia of NWA 773 yielded a U-Pb concordia age of 3953 ± 16 Ma, indicating a significantly more ancient component within the breccia. A 2718 ± 44 Ma weighted average U-Pb age of apatite from the polymict breccia and magnesian gabbro lithologies is interpreted to date the brecciation event that assembled the NWA 773 clan components on the Moon. |

Is Early Development of Large Volcanic Channels Typical of all Rocky Planets? (David Leverington, Texas Tech University),
Lecture Hall
The vestiges of large volcanic channels are preserved at the surfaces of the Moon, Venus, Mercury, Mars, and Io. The largest of these systems have widths of tens of kilometers and lengths of thousands of kilometers. Component channels were incised by voluminous low-viscosity lava flows, and are the surface expressions of magmatic systems that helped to dissipate internal heat accumulated through processes of accretion, differentiation, tidal interactions, and radioactive decay. Most of the more than 200 channels on the Moon are relatively simple systems that developed in the first ~1.5 Ga of solar system history. Lunar channels have widths of up to ~5 kilometers and lengths of up to several hundred kilometers. The more than 200 channels on Venus may have developed during the most recent 1 Ga. Some Venusian systems variously have lengths of thousands of kilometers, widths of tens of kilometers, and channel forms of remarkable complexity. Ten channel systems on Mercury have lengths of up to ~160 km and widths of up to tens of kilometers, and likely developed ~3.7 Ga before present as conduits for flood lavas emplaced across adjacent lowlands. The outflow channels of Mars have lengths of up to thousands of kilometers and widths of up to tens of kilometers, and mainly formed in the first ~1.5 Ga of solar system history. These systems are interpreted by most researchers as products of large aqueous outbursts from aquifers. However, support for aqueous interpretations is weak, and it is increasingly apparent that the characteristics of Martian outflow channels closely match those expected of volcanic systems. Widespread past development of large volcanic channels on rocky bodies beyond Earth suggests the possible formation of analogous systems on the Earth during the Hadean or Archean, a time frame of heightened internal temperatures and eruption of low-viscosity magmas. More generally, the geological record of the inner solar system suggests a predisposition of all rocky planets for early incision of large volcanic channels. |

Comparative Tectonics and Geodynamics of Venus, Earth, and Rocky Exoplanets (#geodyn15) *,
Pasadena, California
Venus and Earth display dramatically different geodynamical and tectonic regimes despite having nearly the same size and bulk composition. Venus lacks evidence of recent plate tectonics but may present analogies with early Earth tectonics. Furthermore, rocky exoplanets likely have a broader range of geodynamic outcomes. This workshop will bring together scientists studying Earth, Venus, and rocky exoplanets to explore the role of key variables such as mass, composition, temperature, atmospheric interaction, and volatiles on tectonic and geodynamic processes, and to compare planetary evolutionary paths within our solar system and beyond. |

Understanding the Role of Volatiles in Shaping the Martian Surface (Patricia Craig, Jet Propulsion Laboratory),
Lecture Hall
Volatiles in the martian crust have played an important role in shaping the surface into what we observe today as seen in the presence of hydrated minerals, such as phyllosilicates and hydrated sulfates. Observations of phyllosilicates and sulfates along with laboratory experiments allows for a ground-truthing of the recent analysis and interpretation of CheMin X-ray diffraction data that has identified phyllosilicate and sulfate minerals in Gale Crater. This has implications for the role of volatiles, specifically water and sulfur, in the formation of such minerals on the surface. Understanding how these minerals formed and were subsequently altered gives vital clues to the history of aqueous conditions on the surface in Mars’ past. In collaboration with scientists at the Astromaterials Research and Exploration Science (ARES) lab at Johnson Space Center, I have been conducting experiments that investigate the effects of acid-sulfate weathering on phyllosilicates with implications for the aqueous history of Mars. In my work, I aim to further understand the global climatic transition from the Noachian to the Hesperian eras on Mars in terms of volatile content in the crust. In this presentation, I will discuss some of my laboratory experiments constraining sulfate formation on the martian surface, the implications for these formation processes on the history of water on Mars and discuss potential collaborations with scientists at ARES. |

Subduction on Jupiter’s Moon Europa: The Case for Plate Tectonics in the Ice Shell (Simon Kattenhorn, ConocoPhillips),
Lecture Hall
Jupiter’s icy moon Europa has one of the youngest planetary surfaces in the Solar System, implying rapid recycling by some mechanism. Despite ubiquitous extension and creation of new surface area at dilational bands that resemble terrestrial mid-ocean spreading zones, there is little evidence of large-scale contraction to balance the observed extension or to recycle aging terrains. We address this enigma by presenting several lines of evidence that subduction may be recycling surface material into the interior of Europa’s ice shell. Using Galileo spacecraft images, we produce a tectonic reconstruction of geologic features across a 134,000 km2 region of Europa and find, in addition to dilational band spreading, evidence for transform motions along prominent strike-slip faults, as well as the removal of approximately 20,000 km2 of the surface along a discrete tabular zone. We interpret this zone as a subduction-like convergent boundary that abruptly truncates older geological features and is flanked by potential cryolavas on the overriding ice. We propose that Europa’s ice shell has a brittle, mobile, plate-like system above convecting warmer ice. Hence, Europa may be the only Solar System body other than Earth to exhibit a system of plate tectonics. These observations are in agreement with theoretical considerations that suggested the plausibility of convection-driven plate tectonics on Europa given its interior shell viscosity, thickness, and thermal structure. |

Tectonic Geomorphology as a Tool to Understand the Structural Geologic History of the Moon (Christian Klimczak, University of Georgia),
Lecture Hall
The Moon hosts several types of large-scale tectonic landforms that are indicative of both extensional and contractional tectonic deformation. High-resolution data returned from the Lunar Reconnaissance Orbiter (LRO) and Gravity Recovery and Interior Laboratory (GRAIL) missions allow us to assess these landforms in great detail. Extensional deformation is evident as large troughs that are interpreted to be graben structures. Grabens on Earth are generally found in rift settings, but also form as surface expressions of dike intrusions. Whether or not a graben is accompanied by a dike can be determined by a detailed analysis of their tectonic geomorphology. Contractional deformation, on the other hand, is manifest as prominent ridges, the largest of which are spatially associated with mare-filled impact basins. Ridges are believed to be the surface expression of one or more shallowly dipping thrust faults, with the ridge morphology representative of the thrust fault architecture at depth. The size and geometry of the landforms correlates with the size and geometry of the tectonic structures producing the landform, and so their morphologic characterization, coupled with numerical modeling provide a detailed set of observations and interpretations for deformation in the lunar subsurface. In this talk, I will show where large-scale graben are found to be associated with dike intrusions, and where mare ridges have been produced by large thrust faults that deeply penetrate the lunar lithosphere. These results increase our understanding of the regional and global tectonic evolution of our Moon in a quantitative manner. |

The 2015 TMT Science Forum,
Washington, DC
The annual Thirty Meter Telescope (TMT) Science Forum brings together members of the international community to meet, collaborate, and plan for future TMT science programs. The Forum is the premier opportunity to learn about the status of the observatory, its instrumentation and adaptive optics systems, and to get involved in shaping the future of TMT. The theme for this year's Forum is “Maximizing transformative science with TMT.” With 9 to 14 times more collecting area than today's 8- to 10m-class telescopes, and 12.5 times better angular resolution than the Hubble Space Telescope in the near-infrared, TMT will enable amazing new science. The 2015 Forum is an opportunity to think ahead about how to maximize the scientific return from TMT through innovative collaborations, telescope operations, data management, and instrumentation development. The meeting will feature presentations about the transformative science enabled by TMT, and then focus on how best to accomplish that science. There will be working sessions devoted to planning for possible “key programs” that could span the international TMT partnership as a means to carry out projects that might exceed the capacity of individual scientists and teams within any single partner. The implications of such programs for TMT operations, and the evolution of its instrumentation suite, will all be discussed. |

Almahata Sitta and Other Polymict Ureilites and Why They Are So Important (Cyrena Anne Goodrich, Planetary Science Institute),
Lecture Hall
Almahata Sitta is the first meteorite observed to originate from an asteroid (2008 TC3) that had been tracked and studied in space before it hit Earth, providing an unprecedented opportunity to correlate properties of an asteroid with properties of the rocks derived from it. Almahata Sitta is also unique because the fallen fragments include a wide variety of different meteorite types. Approximately 70% belong to the ureilite group of achondrites, and 30% are various types of chondrites, including all major classes (ordinary, enstatite, carbonaceous, and also R-chondrites). Almahata Sitta has been classified as an anomalous polymict ureilite. However, maybe it is not so anomalous. Previously known (typical) polymict ureilites also contain a wide variety of foreign clast types. In this regard, all polymict ureilites differ from most other meteoritic breccias, in which the sole foreign clasts are CC matrix-like dark clasts. The foreign clasts in polymict ureilites represent at least 7 different parent asteroids and a wide range of chemical and isotopic environments in the early solar system. How did all these materials become mixed with fragments of ureilites in a single asteroid, and why is this process of mixing not apparent in most other meteorites? I will discuss several hypotheses and their disparate implications for early solar system processes. |

Planetary Systems: A Synergistic View,
Quy Nhon, Vietnam
With exciting new results coming from both exoplanet observations and solar system exploration missions, it sometimes seems that the two fields of "planetary studies" aren't talking to each other. What new insights might come from a synergistic approach to planetary studies, where exoplanet and solar system scientists share data sets, develop and tune models jointly, and encourage postdoctoral fellowships and faculty positions that transcend the exoplanet/solar system divide? |

Thermoluminesence Analysis of Micrometer Fragments of Primitive Extraterrestrial Materials (Jonathan Craig, University of Arkansas),
Lecture Hall
Extraterrestrial materials such as the matrix from un-equilibrated ordinary chondrites (UOCs) and Antarctic micrometeorites (AMMs) represent some of the most primitive solar system materials and as such they retain a memory of early solar system formation processes. There are many techniques which can determine the mineralogical, petrological or compositional information about extraterrestrial materials. Few of these, however, can provide the insight into the history of a material that is possible with thermoluminescence (TL) analysis. Heretofore considered a “bulk sample” technique we have now extended its capability to include single micrometer particle analysis. In addition to the mineralogical information provided by TL analysis it is now possible to decipher the radiation and thermal history of primitive solar system materials on a scale never seen before. TL data has shown fine scale radiation and thermal heterogeneities present in all the materials analyzed to date which, when considering the close proximity of the samples to each other in the host rock, is a startling result. The data suggest that these materials contain highly localized radiation and thermal effects from galactic/solar cosmic ray exposure. Such heterogeneities at this fine scale show unique pre-compaction characteristics of the host rock that were previously hidden from the bulk analysis. |

Planet Signatures from Precision Spectroscopy,
Sao Paulo, Brazil
A wealth of information can be inferred from stellar spectra. The effective temperature, surface gravity, projected rotational velocity, and chemical composition can be readily obtained from standard analyses. The classical approach results in errors in effective temperature of about 50 - 100K, and in errors in chemical abundances of about 0.05 dex. However, predicted signatures of planet formation on the host star’s chemical composition demands both precise stellar parameters (effective temperatures within about 10 K) and precise elemental abundances (0.01 dex). This exquisite precision can be achieved by a careful, strict differential analysis between nearly identical stars (stellar twins), as was demonstrated first using solar twins by Melendez et al. (2009) and Ramirez, Melendez & Asplund (2009). Besides being important to study planet signatures (e.g., Ramirez et al. 2011), high precision is also key to study stellar evolution (e.g., Monroe et al. 2013; Tucci Maia et al. 2015), star clusters (Yong et al. 2013), and Galactic chemical evolution (e.g., Melendez et al. 2014; Nissen 2015). The aim of this hands-on workshop is to train a small group of astronomers (~10) on the strict differential technique. We will discuss with the participants all steps necessary to reach precise abundances, including observations, data reduction, equivalent width measurements, line-by-line analysis, stellar parameters, chemical abundances, and determination of errors. The activities will be led by Jorge Melendez (Univ. São Paulo) and Ivan Ramirez (Univ. Texas at Austin), pioneers of the high precision differential technique. Members of our group will help as tutors, and will also present their own work. During the workshop we will also discuss the different applications of high precision abundances, in particular on planet signatures, but also on the determination of stellar masses and ages, signatures of stellar evolution, and galactic chemical evolution. Members of our group will present different applications, and the participants are welcome to present a talk on their own work. |

Polygonal Patterns and Desert Eyes: Discovery and Study of Pervasively Developed Bedrock Structures in the Western Desert of Egypt Using Freely Available High Resolution Satellite Imagery (Barbara Tewksbury, Hamilton College),
Lecture Hall
Using high resolution satellite imagery, the NSF-funded Desert Eyes Project has discovered and studied bedrock structures that are pervasively developed over literally tens of thousands of square kilometers in the Western Desert of Egypt. That the vast majority of these structures have gone unrecognized before now is a function of 1) the remoteness and lack of topographic relief in large tracts of the Western Desert, 2) the scale and nature of the structures, and 3) the fact that the structures occur on the "Stable Platform" of Egypt, where previous workers have for the most part not gone looking for interesting bedrock structures. The fold structures are big enough in overall size (a few hundred meters across) and have such shallow dips that they are almost impossible to see from ground level given the lack of topographic relief. But, at the same time, the structures are small enough that they remained essentially "hidden" even at the highest resolution of previously available free imagery (e.g., Landsat panchromatic imagery, 15 m/pixel). With the advent of very high resolution imagery in Google Earth (1-2 m/pixel), these structures are suddenly not only spectacularly visible, but micro-topographic features are clear enough to allow significant structural analysis. Over the past five years, the Desert Eyes Project has discovered and documented the first extensive exposure to have been recognized on land of a unique class of faults known as polygonal faults (Tewksbury et al., 2014). Polygonal faults have previously been studied essentially only in marine basins using seismic data. The Project discovered and is investigating a network of hundreds of long, narrow synclines that produce a strong regional patterning in high resolution satellite images over an area of >20,000 km2 in the Western Desert and also in places east of the Nile. The syncline network developed in a narrow time window between Early Eocene deposition of the limestone’s and formation of cross-cutting faults associated with Red Sea rifting. We are currently mapping these structures over a large area in high resolution satellite imagery and have just acquired industry seismic reflection data to pair with our structural mapping. These structures do not have geometries typical of tectonic fold and fault terrains, and we are testing a variety of non-tectonic models for formation of these structures. ------- Desert Eyes is a joint US-Egypt Project funded by an NSF program designed for international collaboration and led out of the Department of Geosciences at Hamilton College in Clinton, NY.. |

Plate Tectonics in Time and Space (Adrian Lenardic, Rice University),
Lecture Hall
The paleomagnetic record, available from oceanic lithosphere, shows that plate tectonics has operated relatively smoothly over the last 150-200 million years of our planets evolution. Data based records extending deeper in geologic time, although not as conclusive, do suggest that the pace of tectonics has changed over our planets geologic lifetime. The observational constraints that are currently available are consistent with the hypothesis that plate tectonics operated in a sporadic ("episodic") mode in the precambrian. Geodynamic models indicate that this type of temporal transition can occur under hotter internal conditions for the early earth (associated with greater radiogenic heating). The combined interpretation of geologic data sets and geodynamic modeling based inferences has implications for understanding: 1) The temporal pace of tectonics over our planets geologic lifetime; 2) Potential tectonic regime transitions over Earth history; and 3) The potential for plate tectonics on other terrestrial planets, both in and beyond our own solar system. I will review the pertinent data, the models that suggest the plausibility of temporal changes in the pace and/or mode or tectonics, and the implications for Earth history and comparative planetology. |

Comparative Climates of Terrestrial Planets II: Understanding How Climate Systems Work,
Moffett Field, California
NASA's Science Mission Directorate (SMD) is delighted to invite the science community to participate in -- and we as Co-Organizers are sincerely happy to announce -- the "Comparative Climates of Terrestrial Planets II: Understanding How Climate Systems Work" conference. This next conference (CCTP2) will be held at the NASA Ames Research Center in Moffett Field, California (close to Mountain View CA and ~40 mi south of San Francisco CA and ~15 mi north of San Jose CA), 8-11 September 2015. The first CCTP meeting was held in Boulder, Colorado 2012, and fostered a series of interdisciplinary conversations on a wide range of planetary climates. We are planning for a similar range of conversations at the CCTP2 meeting, including the effects of the Sun and other stars on the climates of Earth and other planets in and beyond the Solar System. We anticipate the publication of a formal NASA Conference Proceeding (CP) comprised of extended abstracts from this meeting, including abstracts from individual presentations, and an Executive Summary that captures the essence of the presentations and panel discussions during the conference. The theme of this year’s CCTP meeting is "Understanding How Climate Systems Work." We encourage the submission of any research that puts planetary climate in the perspective of a comparative framework, including (but not limited to) the effects from space weather, the parent star, and orbital forcing. Abstract submission will open on 26 March, and will close on 15 May. |

Life in a Cosmic Context,
Trieste, Italy
Four centuries after the Earth was displaced from the center of the universe by the Copernican revolution, times are ripe for terrestrial life to be set in a cosmic context. This task is felt as a priority by a growing number of scientists working on life's origins and Solar System exploration. The discovery of thousands of exoplanets is giving birth to new, life‐oriented fields, such as planetary habitability and the search for atmospheric biomarkers. The Fifth Workshop of the Italian Astrobiology Society will bring together scientists with widely different backgrounds with the aim of discussing fresh results obtained in the above mentioned fields. |

Insights Into the Aqueous History of Mars from Acid-Sulfate Weathered Phyllosilicates (Patricia Craig, Lunar Planetary Institute),
Lecture Hall
Phyllosilicates and sulfates have been identified in close spatial proximity to each other in several locations on Mars, including Gale Crater, Mawrth Vallis, and Endeavour Crater. In many cases, Ca-sulfates are identified with either Fe/Mg-phyllosilicates or Al-phyllosilicates. While several studies have shown that sulfates result from acid sulfate-weathered basalts it is possible that phyllosilicates that formed during Mars’ earlier Noachian (~ 4.1-3.7 Ga) era would have been affected by the prevailing acidic conditions in the later Hesperian (~ 3.7-3.0 Ga). Our acid-weathering experiments showed that interlayer Ca2+ weathers out first and the layered structure of the phyllosilicates (octahedral and tetrahedral layers) can remained intact. The leached Ca2+ combined with SO42- to form Ca-sulfates. This weathering process explains the observations of sulfates in close association with phyllosilicates on Mars and provides valuable insight into the aqueous and geologic history of Mars. |

From Clouds to Protoplanetary Disks: The Astrochemical Link,
Berlin, Germany
Recent advances in sub-millimeter (ALMA, NOEMA) and IR (Spitzer, Herschel, SOFIA) observational facilities and modeling have started to shed more light on the physical and chemical processes governing the evolution of interstellar clouds into pre-stellar cores, protostars, protoplanetary disks, and, eventually, planetary systems. Molecular spectroscopy has played a crucial role in these advances, as only lines can unveil the underlying dynamics and can provide information on the physical and chemical structure across clouds, cores and protoplanetary disks. Furthermore, chemo-dynamical models have become more and more detailed, thanks also to the great advances in (gas phase and surface) laboratory work as well as quantum chemistry calculations, while magneto-hydrodynamical simulations have included simplified chemical codes to test theoretical predictions. We believe this is the right moment to try to summarize a current status quo in this exciting field of astronomy, and to facilitate and foster future directions of astrochemistry research. Since astrochemistry is the trait d'union of different communities, the main goal of this well-focussed meeting will be to bring together observers, theoreticians and experimentalists to present their recent advances, to discuss about the main uncertainties and to plan future developments. Interaction between the different communities will be encouraged and mixed, lengthy discussions will be organized at the end of each session, and in the end of each conference's day. We will particularly encourage young scientists (students, PhD students, post-docs) to participate, with the main aim to help them to shape their knowledge and understanding of modern and forthcoming ideas about details of planet- and star-formation from a cohort of the world-leading experts. |

Rainbows on the Southern Sky: Science and Legacy Value of the ESO Public Surveys and Large Programmes,
Garching, Germany
Since the start of the VLT science operations, about fifteen per cent of the whole science time on La Silla Paranal telescopes has been used for Large Programmes. In the last five years, the Public Surveys on VISTA, VST, VLT and NTT, have beed added to the ESO landscape thus enlarging the offer of large/coherent observing programmes for the community and increasing the legacy value of the data delivered by the ESO telescopes. In 2003 and 2008, ESO organised two workshops to assess the scientific return of Large Programmes; in 2012 the first results from the imaging ESO Public Surveys were also presented to the community. Following the recommendations from the Observing Programmes Committee and Public Survey Panels, ESO now wishes to discuss and put into perspective the scientific results achieved through these programmes together with their teams, the community and representatives of the reviewing panels. The scientific research carried out by members of the community at the Observatory via these Programmes covers all the subjects of observational astronomy. This is celebrated by the diversified scientific program of the workshop organised in six sections: Stars and Planets, Milky Way and Local Group, Extragalactic Astronomy, Galaxy Evolution, High-redshift Universe and Cosmology, Legacy Value of Public Surveys and Large Programmes. The workshop will feature the scientific presentations from all Public Surveys and a representative set of Large Programmes that were completed since the 2008 Large Programme workshop. The astronomers in charge of these Programmes will be invited to present their scientific results and the impact on their field of research. The workshop will include a session on the impact of these ESO programmes and on the developments required to increase the community access to the reduced data. The goal is to enhance their legacy value for the whole astronomical community. |

Space Weathering on Icy Satellites in the Outer Solar System (Roger Clark, Planetary Science Institute),
Lecture Hall
Space weathering produces well-known optical effects in silicate minerals in the inner Solar System, for example, on the Moon. Space weathering from solar wind and UV is expected to be weaker in the outer Solar System simply because intensities are lower.However, cosmic rays from inner to outer solar system would be similar to first order. Similarly with micrometeoroid bombardment. That, combined with the much higher volatility of icy surfaces means there is the potential for space weathering on icy outer Solar System surfaces to show optical effects. The Cassini spacecraft orbiting Saturn is providing evidence for space weathering on icy bodies. The Cassini VIMS instrument has spatially mapped satellite surfaces and the rings from .35-5 microns and the UVIS instrument from 0.1 to 0.2 microns. These data have sampled a complex mixing space between H2O ice and non-ice components and they show some common spectral properties. Similarly, spectra of the icy Galilean satellites and satellites in the Uranian system have some commonality in spectral properties with those in the Saturn system.The UV absorber is spectrally similar on many surfaces. VIMS has identified CO2, H2 and trace organics in varying abundances on Saturn's satellites. We postulate that through the spatial relationships ofsome of these compounds that they are created and destroyed through space weathering effects. For example, the trapped H2 and CO2 observed by VIMS in regions with high concentrations of dark material may in part be space weathering products from the destruction of H2O and organic molecules. The dark material, particularly on Iapetus which has the highest concentration in the Saturn system, is well matched by space-weathered silicates in the .4-2.6 micron range, and the spectral shapes closely match those of the most mature lunar soils,another indicator of space weathered material. |

The Climate History of Mars: Was the Early Mars Climate “Warm and Wet” or “Cold and Icy”? (James W. Head, Department of Geological Sciences, Brown University),
Hess Room - Special Seminar (Note Time and Location)
The current and Amazonian climate of Mars is classified as hyperarid and hypothermal, but the presence of extensive valley networks, open and closed basin lakes, and distinctly different mineralogy in the earlier history of Mars all hint at a "warm and wet" climate in the Noachian. Recent climate models have great difficulty reproducing conditions for a "warm and wet" early Mars, suggesting instead "cold and icy" conditions. We examine the predicted nature of a "cold and icy" early Mars and assess whether such a climate is compatible with the geological evidence. |

Brine Flows on Mars (Lujendra Ojha, School of Earth and Atmospheric Sciences, Georgia Institute of Technology),
Lecture Hall
Determining whether liquid water exists on the Martian surface is central to understanding the hydrologic cycle and potential for extant life on Mars. Brine flows (or seeps) have been proposed to explain the formation of some narrow streaks (termed recurring slope lineae (RSL)) observed on Mars, yet direct spectroscopic evidence was missing. Analysis of spectral data from the Compact Reconnaissance Imaging Spectrometer for Mars instrument onboard the Mars Reconnaissance Orbiter provides the first spectral evidence that recurring slope lineae form as a result of contemporary water activity on Mars. In this talk, I will give a synopsis of RSL activity on Mars, and spectral detection of hydrated salts on the slopes where rsl form. |

International Young Astronomers School on Large Ground-based 21st Century Radio Instruments: ALMA/NOEMA-SKA/LOFAR/NenuFAR,
Paris, France
Since the recent opening of ALMA to the astrophysical community, large ground based observational facilities in the radio centimeter and millimeter range are preparing a new era of radioastronomy for the coming century. In the (sub)millimeter range, ALMA has already provided exciting observations that chalenge our vision of, e.g., star and planetary systems formation processes. The NOEMA project upgrade of the Plateau de Bure interferometer will provide in the northern emisphere a welcomed complement to this world wide observatory. In the near future, LOFAR and the local facility NENUFAR at Nançay Observatory will offer a prefiguration of the major Square Kilometer Array (SKA) project that will open a new window to the distant Universe. All fields of Astrophysics are impacted, from planetary sciences to cosmology and including all scales of galactic studies. However, such large interferometer instruments are far from trivial to use, and getting the best scientific output from the time and ressources invested requires new skills from the coming generation of young astronomers. The goal of the present school is to introduce PhD students and Post-Doc researchers to these exciting developments. They will have the occasion to follow courses from some of the top scientists in the field. Ample time for discussions is scheduled, as well as various hands on sessions. |

Polar Regolith Workshop Without Walls,
Virtual meeting
NASA's Solar System Exploration Research Virtual Institute (SSERVI) exists to integrate solar system science with the exploration needs of the human spaceflight program to explore space beyond low-Earth orbit. Those efforts may involve measurements that address strategic knowledge gaps, the development of mission concepts, and the identification of space resources that enhance exploration activities. A specific request for assistance has emerged from HEOMD that addresses plans to evaluate, and potentially exploit, ices and other volatile elements in the polar regions of the Moon. With that purpose in mind, SSERVI is organizing a 1-day virtual workshop that will bring together our current body of knowledge of the regolith properties in Permanently Shadowed Regions (PSRs) that might affect the trafficability of robotic rovers, such as NASA's Resource Prospector mission. A few keynote presentations will help frame the issues involved and summarize recent published results with contributed presentations and discussion periods rounding out the program. |

Evolving Worlds: A Story of Planetary Evolution and Bi-Stability (Matthew Weller, Rice University),
Lecture Hall
Growing geodynamic and geochemical evidence suggests that plate tectonics may not have operated on the early Earth, with both the timing of its onset and the length of its activity far from certain. This work uses coupled 3D mantle convection and planetary tectonics simulations to explore evolutionary paths and planetary tectonic regimes. Early in the geologic lifetime of a terrestrial planet, high mantle temperatures favour stagnant-lids. As radiogenics decay, an initial stagnant-lid may yield into a high temperature mobile-lid state. The transition from an initial stagnant-lid is a function of yield strength, in addition to both internal and surface temperatures. For intermediate values of internal temperature, multiple stable tectonic states can exist. In these regions of parameter space, the specific evolutionary path of the system has a significant role in determining its tectonic state. This indicates that multiple modes of convection and surface tectonics can potentially operate on a single planetary body at different times in its evolution, as consequence of changing internal parameters, surface temperatures, and differing thermal histories. The implications of terrestrial worlds that can alternate, and be offset between multiple tectonic states over giga-year timescales will be discussed. |

4th ELSI Symposium: Three Experiments in Biological Origins,
Tokyo, Japan
We will summarize the formation and early environment of Venus, the Earth and Mars and place them into context relative to each other, and to a lesser degree to other planets and exoplanets. We aim to determine what conditions on Earth were favourable for the onset of chemical cycles that eventually led to a thriving biosphere, and whether our neighbours may have once harboured such conditions. Why did Earth succeed where the others failed? |

Bridging Disciplinary Perspectives to See Further Into Life's Origins,
Galveston, Texas
The research required to understand life's origins occurs at a point where multiple scientific disciplines meet. Chemists, biologists, physicists, geoscientists, planetary scientists, astronomers, meteoriticists, mathematicians and computer scientists are among those contributing to progress. Combining the findings of each discipline into a composite narrative produces multidisciplinary science. The origins research community has come far in this endeavor. More challenging is to extend these connections into true interdisciplinarity, wherein the insights of one research community influence the interpretation of data and questions being asked by others. The forthcoming Gordon Research Conference will explore this transition, from multidisciplinarity to interdisciplinarity. It will visit the traditional array of topics, from LUCA to the non living universe. It will emphasize, however, speakers whose work crosses traditional disciplinary boundaries. It will create spaces where scientists from different disciplines are challenged to build bridges of knowledge between their respective areas of expertise. The GRC will integrate with the preceding GRS (Gordon Research Seminar) by asking the latter to report forwards where they see important, emerging connections - in presentations, discussion panels and questions to the conference. |

The History of Qarabawi's Camel Charm: A Meteoritic Artifact (Rhiannon Mayne, Texas Christian University),
Lecture Hall
Meteoritics, the study of meteorites, is usually focused on the scientific value of a sample; for example, what can it tell us about the formation of our Solar System, the planets, how Earth formed? It is rare for the cultural value of meteorites to be the focus, although there are a few examples. The Camel Charm is a meteoritic artifact acquired by the National Meteorite Collection at the Smithsonian’s National Museum of Natural History in 1974. It has never been studied. The Charm is made from an iron meteorite with an average Ni-content of 7.8%, which is identical (within error) to a previously identified meteorite called Wabar. It is possible that the Camel Charm represents a piece of Wabar that was traded to the Ababda in Egypt from its original home in Saudia Arabia. The Camel Charm is a unique meteorite from an ethnographic standpoint, with a very interesting history. It is valuable addition to the National Meteorite Collection. |

Effects of mechanical, rheological and tectonic controls on the formation of giant radial dike systems on Venus: Insights from finite element modeling. (Nicolas LeCorvec, Lunar and Planetary Institute),
Lecture Hall
Radial dike systems are intriguing magmato-tectonic features occurring on Venus, Earth and Mars. For such systems to form, massive quantities of magma ascending from the mantle must be redirected laterally at shallow depths within the lithosphere over several hundred kilometers. Observations have shown different patterns from continuous fanning to subswarms of subparallel dikes. As magma ascends towards the surface, accumulation in reservoirs situated at various depths within the lithosphere is often coupled with the growth of a volcanic edifice at the surface. The stability of magma reservoirs, and therefore the generation of magmatic intrusions, is influenced by their shape, their location, the tectonic environment and the mechanical and rheological properties of the lithosphere. Based on previous work investigating the role of flexure on the stability of magma reservoirs, we developed new models to test: 1- the role of a mechanically-layered lithosphere; 2- the role of extensional stresses; and 3- the ellipticity of magmatic reservoirs on the formation of these radial dike systems. To explore these scenarios, we used the COMSOL Multiphysics finite element package allowing us to develop: 1- 2D axisymmetric elastic models made of mantle and crustal components; 2- 3D elastic models in which an extensional stress was applied; and 3- elliptical magmatic reservoirs embedded within 2D axisymmetric elastoplastic models. Different tectonic environments were studied: lithostatic, upward flexure due to uplift consistent with a plume-derived origin and downward flexure due to the load of a volcanic edifice. Mechanical layering within the lithosphere impacts the location of failure along a magmatic reservoir and the type of magmatic intrusions. We observe that shallow magma reservoirs in an upward flexure environment tend to produce radial dikes. Regional Extensional stresses in 3D tend to focus the location of failure along the magma reservoir, therefore limiting the formation of continuous fanning pattern. Finally, the elliptical shape of a magma reservoir favors continued expansion and increasing ellipticity, because failure at the midsection requires less overpressure as the ellipticity of the reservoir increases. These results highlight new physical and structural controls on the formation of radial dike systems on Venus. Specifically, we can infer 1- potential crust/mantle ratios within the Venusian lithosphere; 2- the extensional stress regime linked to the formation of specific radial dike systems; and 3- the mechanisms of magma chamber growth linked to the formation of calderae observed in conjunction with radial dike systems on Venus. |

Crustal structure of the South-Pole Aitken Basin from GRAIL and LOLA (Peter James, Lamont-Doherty Earth Observatory at Columbia University),
Lecture Hall
The Moon's South Pole-Aitken basin (SPA) is the largest confirmed impact basin on the Moon, and it delineates one of the ~4 major lunar terranes. The gravity and topography data from GRAIL and LOLA respectively provide an opportunity to study the structure the crust and mantle under SPA. Long-wavelength gravity and topography are sensitive to the uppermost several hundred kilometers of the lunar interior, and are consequently sensitive to mass heterogeneities in the lunar mantle. Short wavelength gravity and topography data primarily reveal the bulk densities of the crust. Remote sensing instruments such as the Moon Mineralogy Mapper have detected the presence of anorthosites, pyroxenes, and olivines in various parts of the basin, but ambiguities remain: it is not known whether surface compositions are representative of the crust as a whole, and absolute abundances of mafic components are poorly constrained. By correcting for the distribution of porosity in the lunar crust, I use gravity and topography to estimate the grain densities of various crustal features in SPA. In particular, the rings and peak-rings of basins superimposed on SPA offer an opportunity to sample compositions of materials that originated deep within SPA’s impact melt sheet. |

Shock Chemistry of Simple Sugars: Production of Biologically Relevant Compounds in Impacts (Nicolle Zellner, Albion College),
Lecture Hall
The identification of over 100 different sugars, sugar acids, amino acids, and other biologically relevant molecules in the Murchison meteorite has spurred interest in the field of prebiotic chemistry. Questions regarding the origins of these compounds are many. For example, are they native to the meteorite? If so, how were they formed? Could they have been formed in the shock event that occurred when the meteorite fell to the Earth? In this talk, I will describe our recent experiments where we explore the reactivity of two simple sugars, glycolaldehyde and dihydroxyacetone, catalyzed by mineral surfaces. I will also present the results of laboratory impact experiments where these sugars and mineral matrices were subjected to reverberated shocks from 5 GPa to >25 GPa. Our experiments show that the production of larger molecules (with up to six carbons) is accelerated under the conditions that simulate impacts by extraterrestrial objects. Scenarios for the production of these molecules via impact delivery by asteroids or comets will be explored. |

Solar System Observations with the Arecibo Planetary Radar System (Patrick Taylor, Arecibo Observatory),
Lecture Hall
Arecibo Observatory in Puerto Rico houses the largest and most sensitive single-dish radio telescope and the most active and powerful planetary radar system in the world. The radar system on the 305-m William E. Gordon telescope has been used to study objects in the Solar System since its construction in 1963, from Mercury out to Saturn and all solid bodies in between. I will discuss the history of planetary radar at Arecibo and its applications to Solar System astronomy with specific attention paid to observations of near-Earth objects. Radar observations of near-Earth asteroids are critical for identifying those objects that may present a hazard to Earth and providing detailed physical characterizations in terms of size, shape, spin, and surface-property (reflectivity, polarization, geologic features and sometimes composition and density) information. In fact, radar investigations of many near-Earth objects are roughly equivalent in terms of their science content to space flyby missions, but at a cost orders of magnitude less making radar arguably the most powerful ground-based method for post-discovery characterization of the near-Earth object population. |
