Astrobiology Workshop: Open Questions on the Origins of Life

Workshop: OPEN QUESTIONS ON THE ORIGINS OF LIFE
SAN SEBASTIAN, SPAIN, MAY 20-23, 2009
Organizers: Pier Luigi Luisi and Kepa Ruiz-Mirazo

The overall idea behind this workshop is to tackle a number of key questions about the origin of life that still remain unanswered, attempt to clarify why it is so, and to discuss how to progress in our efforts to answer these questions.

In the field of the origins of life, as in many other fields, there is a tendency and a danger for all of us to keep working in our own, fairly narrow areas of expertise and ignore "the big picture". Thus, from time to time, it is important to ask "where are we in the field and what are the main stumbling blocks on the road?" A similar meeting was already held, in a preliminary form, in Erice, Sicily, in 2006. It created a considerable interest so many researchers asked that we continue the experiment in a more developed form. In fact, one conclusion of the Erice meeting was that it should be repeated, possibly on regular basis (every 2-3 years) and involved more countries and a larger number of young researchers.

The results of this meeting, in terms of abstracts and short communications, will be published in a special issue of Origins of Life and Evolution of the Biosphere, as it was the case after the Erice meeting, or in another international journal in the field.

2009 is an excellent year for this type of meeting, as it is the bicentenary of Charles Darwin's birth, on the 12th of February 1809, and the 150th anniversary of the publication of Origin of Species, on November 24th, 1859. Therefore, our workshop will be a contribution to a host of events that will be organized around the world to celebrate this special anniversary.

The format of the workshop will be quite different from formats of other meetings in the field. Eight questions were chosen from the initial list of 14 questions on the basis of the feedback from potential contributors and a wide representation of the community of researchers interested in the field of origins of life. These questions are:

1. To what extent the origins of life were deterministic or based on contingency?
2. Is life an emergent property?
3. Was the origin of life heterotrophic or autotrophic?
4. What were the origins of catalytic cycles?
5. How plausible is the "RNA world" hypothesis?
6. How to bridge a gap between the protocellular world and the minimal cell?
7. Is life a unity or confederacy?
8. How to define the very origin of life?

The meeting will consist of 8 sessions spread over 4 days (one session in the morning and one in the afternoon). Each session will focus on a single question, and each of 3 panelists (the speakers) will directly address it in brief (20 min) presentations. The presentations will be followed by a discussion between the panelists and one hour of open discussion.
The participants will be divided into small groups, 4-5 people each. Every group will have 30 min to discuss the contributions of the panelists and prepare questions, comments or criticisms. Then, one representative of each group will present these comments to all other participants (max. 10min.). This will be followed by brief answers from the panelists. Thus, each session will last approximately 3.5 hours. This format is aimed at involving all participants, especially young researchers.

ASGSB seeks student delegates for Congressional Visit Day

Dear Colleagues,

The American Institutue for Astronautics and Aeronautics (AIAA) is again organizing a Congressional Visit Day, to occur this year on March 17 - 18 in Washington, DC. As in recent years, the ASGSB will have representatives in the delegation that fans out across Capitol Hill, visiting key congressional offices to educate staffers involved with senators and representatives with interests and committee assignments that are relevant to NASA activities. It is especially effective to have young, informed, enthusiastic and articulate students representing current and future activities in the space life sciences. We are fortunate that the AIAA is inviting student participation in the delegation.

I write to invite nominees for ASGSB Student Delegates for CVD on March 17-18. Transportation and expenses will be covered for one, or possibly two ASGSB students. Please send your nominations, along with a CV for each student to my assistant, Ms. Barbara Grinder, bgrinder (at) indiana.edu.

Best wishes,

Jeffrey R. Alberts
President, ASGSB

The Limits to Life in a Fertile Universe

Message from the Center Director Revised: Ames Takes On...The Vatican?

Well, not exactly. But at 7 p.m. on Thursday, February 19, Ames' own Lynn Rothschild will engage Father George Coyne, Director Emeritus of the Vatican Observatory (and my college adviser) on "The Limits to Life in a Fertile Universe." I will moderate as they consider the fact that while the potential for life was present at the Big Bang, the only place that the promise may have been realized is planet Earth. George Coyne, an astronomer and Jesuit priest, and Lynn Rothschild, an evolutionary biologist and astrobiologist, will approach this question from their different perspectives. They will consider what niches life may have found since the Big Bang, and muse on the significance of the fertile universe.

The talk will take place in the ballroom in Building 3 at 7 p.m. on February 19, 2009. It is being jointly hosted by ARC, the Commonwealth Club and the Yale Club. The event is open to the public; admission is $10, payable in advance or in cash at the door. If you wish to pay in advance via credit card, please contact Georgette Gehue of the Commonwealth Club at (408) 280-5842 or at email address ggehue@commonwealthclub.org. She will add your name to the list of attendees. She can also reserve a spot for you even if you pay at the door.

Light refreshments will be served.

I think this will be an extremely interesting exchange of ideas, and hope you will be able to join us.

S. Pete Worden
Center Director

The MARTE VNIR Imaging Spectrometer Experiment: Design and Analysis

Astrobiology. October 2008, 8(5): 1001-1011.
http://www.liebertonline.com/doi/pdfplus/10.1089/ast.2007.0142

We report on the design, operation, and data analysis methods employed on the VNIR imaging spectrometer instrument that was part of the Mars Astrobiology Research and Technology Experiment (MARTE). The imaging spectrometer is a hyperspectral scanning pushbroom device sensitive to VNIR wavelengths from 400-1000 nm. During the MARTE project, the spectrometer was deployed to the Rio Tinto region of Spain. We analyzed subsets of three cores from Rio Tinto using a new band modeling technique. We found most of the MARTE drill cores to contain predominantly goethite, though spatially coherent areas of hematite were identified in Core 23. We also distinguished non Fe-bearing minerals that were subsequently analyzed by X-ray diffraction (XRD) and found to be primarily muscovite. We present drill core maps that include spectra of goethite, hematite, and non Fe-bearing minerals. Astrobiology 8, 1001-1011.

The Subsurface Geology of Rio Tinto: Material Examined During a Simulated Mars Drilling Mission for the Mars Astrobiology Research and Technology Experiment (MARTE)

Astrobiology. October 2008, 8(5): 1013-1021.
http://www.liebertonline.com/doi/pdfplus/10.1089/ast.2006.0107

The 2005 Mars Astrobiology Research and Technology Experiment (MARTE) project conducted a simulated 1-month Mars drilling mission in the Rio Tinto district, Spain. Dry robotic drilling, core sampling, and biological and geological analytical technologies were collectively tested for the first time for potential use on Mars. Drilling and subsurface sampling and analytical technologies are being explored for Mars because the subsurface is the most likely place to find life on Mars. The objectives of this work are to describe drilling, sampling, and analytical procedures; present the geological analysis of core and borehole material; and examine lessons learned from the drilling simulation.

Drilling occurred at an undisclosed location, causing the science team to rely only on mission data for geological and biological interpretations. Core and borehole imaging was used for micromorphological analysis of rock, targeting rock for biological analysis, and making decisions regarding the next day's drilling operations. Drilling reached 606 cm depth into poorly consolidated gossan that allowed only 35% of core recovery and contributed to borehole wall failure during drilling. Core material containing any indication of biology was sampled and analyzed in more detail for its confirmation. Despite the poorly consolidated nature of the subsurface gossan, dry drilling was able to retrieve useful core material for geological and biological analysis. Lessons learned from this drilling simulation can guide the development of dry drilling and subsurface geological and biological analytical technologies for future Mars drilling missions. Astrobiology 8, 1013-1021.

Visible-Near Infrared Point Spectrometry of Drill Core Samples from Rio Tinto, Spain: Results from the 2005 Mars Astrobiology Research and Technology Experiment (MARTE) Drilling Exercise

Astrobiology. October 2008, 8(5): 1049-1060.
http://www.liebertonline.com/doi/pdfplus/10.1089/ast.2007.0146


Sampling of subsurface rock may be required to detect evidence of past biological activity on Mars. The Mars Astrobiology Research and Technology Experiment (MARTE) utilized the Rio Tinto region, Spain, as a Mars analog site to test dry drilling technologies specific to Mars that retrieve subsurface rock for biological analysis. This work examines the usefulness of visible-near infrared (VNIR) (450-1000 nm) point spectrometry to characterize ferric iron minerals in core material retrieved during a simulated Mars drilling mission. VNIR spectrometry can indicate the presence of aqueously precipitated ferric iron minerals and, thus, determine whether biological analysis of retrieved rock is warranted. Core spectra obtained during the mission with T1 (893-897 nm) and T2 (644-652 nm) features indicate goethite-dominated samples, while relatively lower wavelength T1 (832-880 nm) features indicate hematite. Hematite/goethite molar ratios varied from 0 to 1.4, and within the 880-898 nm range, T1 features were used to estimate hematite/goethite molar ratios. Post-mission X-ray analysis detected phyllosilicates, which indicates that examining beyond the VNIR (e.g., shortwave infrared, 1000-2500 nm) will enhance the detection of other minerals formed by aqueous processes.

Despite the limited spectral range of VNIR point spectrometry utilized in the MARTE Mars drilling simulation project, ferric iron minerals could be identified in retrieved core material, and their distribution served to direct core subsampling for biological analysis. Astrobiology 8, 1049-1060.

Underground Habitats in the Rio Tinto Basin: A Model for Subsurface Life Habitats on Mars

Astrobiology. October 2008, 8(5): 1023-1047.
http://www.liebertonline.com/doi/pdfplus/10.1089/ast.2006.0104

A search for evidence of cryptic life in the subsurface region of a fractured Paleozoic volcanosedimentary deposit near the source waters of the Rio Tinto River (Iberian pyrite belt, southwest Spain) was carried out by Mars Astrobiology Research and Technology Experiment (MARTE) project investigators in 2003 and 2004. This conventional deep-drilling experiment is referred to as the MARTE ground truth drilling project. Boreholes were drilled at three sites, and samples from extracted cores were analyzed with light microscopy, scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy. Core leachates were analyzed with ion chromatography, and borehole fluids were analyzed with ion and gas chromatography. Key variables of the groundwater system (e.g., pO2, pH, and salinity) exhibit huge ranges probably due to surficial oxygenation of overall reducing waters, physical mixing of waters, and biologically mediated water-rock interactions.

Mineral distribution is mainly driven by the pH of subsurface solutions, which range from highly acidic to neutral. Borehole fluids contain dissolved gases such as CO2, CH4, and H2. SEM-EDS analyses of core samples revealed evidence of microbes attacking pyrite. The Rio Tinto alteration mechanisms may be similar to subsurface weathering of the martian crust and provide insights into the possible (bio)geochemical cycles that may have accompanied underground habitats in extensive early Mars volcanic regions and associated sulfide ores.

NASA Graduate Student Researchers Program: Chemical sensors development for space and terrestrial applications

NASA Ames has developed a nanosensor technology for high sensitive and low power chemical sensing using nanostructure, single walled carbon nanotubes (SWNT's), combined with silicon-based micro fabrication and micromachining process. Due to large surface area, low surface energy barrier and high thermal and mechanical stability, nanostructured chemical sensors offer higher sensitivity, lower power consumption and a more robust solution than most state-of-the art systems making them attractive for space and defense applications, as well as a variety of commercial applications. Leveraging the micromachining technology, the light weight and compact sensors can be fabricated, in wafer scale for mass production, with high yield and at low cost. Such sensors have drawn attention from the space community for global weather monitoring, space exploration, life search in the universe, and launch pad fuel leak detection and in-flight cabin monitoring and engine operation monitoring.

Additionally, the wireless capability of such sensors can be leveraged to network mobile and fixed-base detection and warning systems for civilian population centers, military bases and battlefields, as well as other high-value or high-risk assets and areas of industry. The objectives of this opportunity are: 1)Exploit new nanostructured materials for chemical sensing, 2)select a combination of materials to form a sensor array for high sensitive and high selective chemical detection, 3) evaluate new sensors for space and terrestrial applications. The project in this opportunity is a multi-disciplinary research and development effort, which involves chemistry, materials science, micro/nano fabrication and instrumentation Deadline: 5:00 PM EST February 1, 2009. http://fellowships.hq.nasa.gov/gsrp/research/detail.cfm?oppID=854

NASA Graduate Student Researchers Program: Astromineralogy of Comets and Protoplanetary Disks

Comets are the deep freezers of dust and ices extant in the early solar nebula at the time of the formation of the giant planets. Astromineralogy is the study of the chemical and structural properties of the dust grains. Studying the dust mineralogy in comets and protoplanetary disks, and, in particular, the amorphous and crystalline silicates, probes the relative abundances of interstellar grains and grains thermally altered or condensed in the inner hot regions of disks, respectively. Research combines analysis and modeling of Spitzer and ground-based spectroscopy of comets as well as radiative transfer modeling of protoplanetary disks to further our understanding of the thermal processing and radial transport of dust in protoplanetary disks at the early epochs of planetesimal formation.

NASA Graduate Student Researchers Program: Planetary Science - Mars

This research focuses on the general circulation and climate system of Mars. There have been 7 successful spacecraft missions to Mars in the past 10 years returning valuable new data about the thermal structure of the atmosphere, the seasonal cycles of dust, water, and carbon dioxide, and the nature of the surface and subsurface. Our group interprets these data using a Mars General Circulation Model. We use the model to simulate the observations and determine what physical and dynamical processes are responsible for them. The model includes a full surface heat budget, a cloud microphysics package, a two-stream radiation code for gases and aerosols, a level-2 boundary layer scheme, mass conserving tracer transport algorithms, and CO2 condensation/sublimation physics. Topics we are currently studying include coupling between the present day dust, water, and CO2 cycles, the effect of orbital changes on past climates, and the nature of the early Martian atmosphere when surface pressures were thought to be higher than they are today. The goal of this work is to understand how the Martian atmosphere and climate system have evolved through time. Deadline: Feb 1, 2009 http://fellowships.hq.nasa.gov/gsrp/research/detail.cfm?oppID=33
