Recap of the Western Championship Tournament of the NASA Astrobiology Debates
The Western Championship Tournament of the NASA Astrobiology Debates series was held at the University of Washington, Seattle on October 17-18th. University debate teams from all over the country competed, including Central Michigan University, George Fox University, The George Washington University, Gonzaga University, Harvard University, MIT, Seattle University, US Air Force Academy, UC Berkeley, University of Texas, University of Washington, and Yale University. All teams worked with this topic: Resolved: An overriding ethical obligation to protect and preserve extraterrestrial microbial life and ecosystems should be incorporated into international law.
In the final, which was webcast live from Seattle on October 18th, George Washington University (affirmative) took on Yale (negative), and GW emerged victorious with a score of 4-3 from the judging panel. The Western Champions will join winners of future NASA Astrobiology Debates on a study tour next year to a NASA Center, touring facilities and meeting with scientists to gain deeper insight into the search for life elsewhere.

Moh El-Naggar, a member of the NAI Life Underground team at the University of Southern California has been appointed the first Robert D. Beyer Early Career Chair in Natural Sciences at USC. The appointment, designed specifically for early career scholars, enables the chair holders “to be risk takers because they now have an underpinning of support that gives them the freedom to do the extra work we really expect of great faculty,” says USC Provost Michael Quick.
El-Naggar heads the NanoBio Lab and is known as a pioneer in the area of energy conversion and charge transmission at the interface between living cells and synthetic surfaces, with work that may lead to the linking of cellular biology and chemistry to nanotechnology. His previous awards include the Presidential Early Career Award for Scientists and Engineers and the Young Investigators Program Award.
Cassini Plunged Into Icy Plumes of EnceladusThis unprocessed view of Saturn's moon Enceladus was acquired by NASA's Cassini spacecraft during a close flyby of the icy moon on Oct. 28, 2015. Credits: NASA/JPL-Caltech/Space Science Institute
The Cassini spacecraft took a daring plunge on October 28, 2015 into the icy geysers of Saturn’s moon Enceladus last week in search of telltale signs of a habitable environment. The encounter with the mysterious plume lasted only tens of seconds as Cassini hurtled past at a speed of about 19,000 miles per hour, yet in these critical moments up to 10,000 particles per second were sampled and identified using the probe’s cosmic dust analyzer. Analysis of this data could provide the most promising signs of habitability yet in the decade since Cassini’s initial flyby of the moon in 2005.

Ten of the best FameLabbers of Season 3 gathered in San Francisco in early November as part of the Bay Area Science Festival. As the crowd cheered them on, each one took the stage for 3 minutes and explained their research to a panel of judges—from ant behavior, to the origins of life in the Universe, to using a dust made from diamonds to purify drinking water!
The winner is a climate scientist—Ilissa Ocko of the Environmental Defense Fund—who discussed different types of pollutants and their relative roles in overall climate change. Ilissa will go on to compete in the National Final in Spring, 2016 where we’ll have a special Master Class on science communication. The winner there will go on to represent the United States in the International FameLab Final at the Cheltenham Science Festival in the UK in June, 2016.
Many Worlds: The Exoplanet EraCredit: NExSS
The search for life beyond Earth has gone beyond Mars, Europa and our solar system to the billions of planets now known to orbit distant stars. A new, NASA-sponsored website that will explore the science and scientists of this cutting-edge and fast-growing field is available at www.manyworlds.space.
The site grew out of NASA’s Nexus for Exoplanet System Science (NExSS) initiative, an interdisciplinary endeavor to help differentiate between planets in the Universe that are 'habitable’ and those that are 'inhabited.’ The goal of NExSS is to bring together researchers from the different communities NASA funds to answer these questions.Many, and perhaps most stars have solar systems with numerous planets, as in this artist rendering of Kepler 11.

The site is authored by Marc Kaufman — writer of two books on space and a former reporter and editor for The Washington Post and Philadelphia Inquirer. Guest columnists appear regularly. If you are interested in what researchers are beginning to learn about the attributes of these distant worlds, take a look at the site, feel free to comment, and pass it on to friends and colleagues who might share your curiosity.
New Exoplanet Habitability IndexImage Source: NASA
Source: [University of Washington]
Scientists have developed a habitability index to rank exoplanets and their potential for increasing our knowledge of life in the universe, described in the forthcoming research paper, “Comparative Habitability of Transiting Exoplanets,” to be published in the Astrophysics Journal. The ranking system created at the Virtual Planetary Laboratory (VPL) will help narrow down which exoplanet candidates in a habitability zone present the best transit data and planetary properties for future observation.
A press release was published by UW Today.
The study was funded by the NASA Astrobiology Institute.
The Search for the Origin of LifeImage: PBS LearningMedia
The Search for the Origin of Life, a documentary by Devon Riter and Daniel Schmidt, follows NASA Astrobiology Institute scientists as they explore the question: How did life on our planet begin? Their research takes them all around the globe and into extreme environments, from arctic glaciers to thermal hot springs to deep into caves. The program originally aired on PBS and is also now available for viewing through the Montana PBS website.
PBS LearningMedia provides teaching resources to accompany the program.

NASA-funded researchers at the Georgia Institute of Technology are tapping information in the cells of all life on Earth, and using it to trace life’s evolution. They have learned that life is a master stenographer; writing, rewriting, and recording its history in elaborate biological structures.
Some of the keys to unlocking the origin of life lie encrypted in the ribosome, life’s oldest and most universal molecule. Today’s ribosome converts genetic information (RNA) into proteins that carry out various functions in an organism. But the ribosome itself has changed over time. Its history shows how simple molecules joined forces to invent biology, and its current structure records ancient biological processes that occurred at the root of the Tree of Life, some 3.8 billion years ago.
By examining variations in the ribosomal RNA contained in modern cells, scientists can visualize the timeline of life far back in history, elucidating molecular structures, reactions, and events near the biochemical origins of life.
The full press release is available at the Georgia Tech website.
The study is reported in the journal Proceedings of the National Academy of Sciences. The research was funded in part by the NASA Astrobiology Institute.
A video produced by Georgia Tech to accompany the published research explains the central dogma of molecular biology, molecular symbiosis, and the origin of the translation system.
NASA Mission Reveals Speed of Solar Wind Stripping Martian AtmosphereArtist’s rendering of a solar storm hitting Mars and stripping ions from the planet's upper atmosphere. Credits: NASA/GSFC
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission has identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported surface life to the cold, arid planet Mars is today.
MAVEN data have enabled researchers to determine the rate at which the Martian atmosphere currently is losing gas to space via stripping by the solar wind. The findings reveal that the erosion of Mars’ atmosphere increases significantly during solar storms. The scientific results from the mission appear in the Nov. 5 issues of the journals Science and Geophysical Research Letters.
“Mars appears to have had a thick atmosphere warm enough to support liquid water which is a key ingredient and medium for life as we currently know it,” said John Grunsfeld, astronaut and associate administrator for the NASA Science Mission Directorate in Washington. “Understanding what happened to the Mars atmosphere will inform our knowledge of the dynamics and evolution of any planetary atmosphere. Learning what can cause changes to a planet’s environment from one that could host microbes at the surface to one that doesn’t is important to know, and is a key question that is being addressed in NASA’s journey to Mars.”
MAVEN measurements indicate that the solar wind strips away gas at a rate of about 100 grams (equivalent to roughly 1/4 pound) every second. “Like the theft of a few coins from a cash register every day, the loss becomes significant over time,” said Bruce Jakosky, MAVEN principal investigator at the University of Colorado, Boulder. “We’ve seen that the atmospheric erosion increases significantly during solar storms, so we think the loss rate was much higher billions of years ago when the sun was young and more active.”
In addition, a series of dramatic solar storms hit Mars’ atmosphere in March 2015, and MAVEN found that the loss was accelerated. The combination of greater loss rates and increased solar storms in the past suggests that loss of atmosphere to space was likely a major process in changing the Martian climate.
The solar wind is a stream of particles, mainly protons and electrons, flowing from the sun’s atmosphere at a speed of about one million miles per hour. The magnetic field carried by the solar wind as it flows past Mars can generate an electric field, much as a turbine on Earth can be used to generate electricity. This electric field accelerates electrically charged gas atoms, called ions, in Mars’ upper atmosphere and shoots them into space.
MAVEN has been examining how solar wind and ultraviolet light strip gas from of the top of the planet’s atmosphere. New results indicate that the loss is experienced in three different regions of the Red Planet: down the “tail,” where the solar wind flows behind Mars, above the Martian poles in a “polar plume,” and from an extended cloud of gas surrounding Mars. The science team determined that almost 75 percent of the escaping ions come from the tail region, and nearly 25 percent are from the plume region, with just a minor contribution from the extended cloud.
Ancient regions on Mars bear signs of abundant water – such as features resembling valleys carved by rivers and mineral deposits that only form in the presence of liquid water. These features have led scientists to think that billions of years ago, the atmosphere of Mars was much denser and warm enough to form rivers, lakes and perhaps even oceans of liquid water.
Recently, researchers using NASA’s Mars Reconnaissance Orbiter observed the seasonal appearance of hydrated salts indicating briny liquid water on Mars. However, the current Martian atmosphere is far too cold and thin to support long-lived or extensive amounts of liquid water on the planet’s surface.
“Solar-wind erosion is an important mechanism for atmospheric loss, and was important enough to account for significant change in the Martian climate,” said Joe Grebowsky, MAVEN project scientist from NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “MAVEN also is studying other loss processes — such as loss due to impact of ions or escape of hydrogen atoms — and these will only increase the importance of atmospheric escape.”
The goal of NASA’s MAVEN mission, launched to Mars in November 2013, is to determine how much of the planet’s atmosphere and water have been lost to space. It is the first such mission devoted to understanding how the sun might have influenced atmospheric changes on the Red Planet. MAVEN has been operating at Mars for just over a year and completed its primary science mission on Nov. 16.

A team of NASA-funded scientists has solved an enduring mystery from the Apollo missions to the moon – the origin of organic matter found in lunar samples returned to Earth. Samples of the lunar soil brought back by the Apollo astronauts contain low levels of organic matter in the form of amino acids. Certain amino acids are the building blocks of proteins, essential molecules used by life to build structures like hair and skin and to regulate chemical reactions.
Since the lunar surface is completely inhospitable for known forms of life, scientists don’t think the organic matter came from life on the moon. Instead, they think the amino acids could have come from four possible sources.
The full story is available on the NASA website.
The research, “The origin of amino acids in lunar regolith samples,” is published in Geochimica et Cosmochimica Acta.
The program was supported by NASA’s Lunar Advanced Science and Exploration Research (LASER), the NASA Astrobiology Institute, and the Goddard Center for Astrobiology.
Free Oxygen in the Late ArcheanBands of the late Archean Mt. McRae Shale from the ABDP-9 core. The drill project was supported by the NASA Astrobiology Program and the National Science Foundation. Image Credit: Arizona State University photo by Tim Trumble
A study on selenium (Se) isotopes in Australia’s Mount McRae Shale supports the theory that oxygenic photosynthesis originated long before the Great Oxidation Event (GOE), which occurred around 2.3 billion years ago. The Mount McRae Shale is a 2.5 billion-year-old formation and holds a record of enrichment and abundance of Se isotopes. The formation provides a means of studying levels of oxygen in both the ocean and atmosphere over Earth’s history, and indicates that there was a 'whiff of oxygen’ in the atmosphere prior to the GOE.
The study, “Selenium isotopes support free O2 in the latest Archean,” was published in the journal Geology. Samples for the study came from a 100 meter section of the ABDP-9 drill core, drilled by the NASA Astrobiology Drilling Program in 2004.
A New Model for HomochiralityA computer simulation with red as the "right hand" chiral molecule and blue as the "left hand" chiral molecule, showing homochirality emerging over time. Image credit: Nigel Goldenfeld Lab, University of Illinois.
A team of NAI scientists working at the Carl R. Woese Institute for Genomic Biology (IGB) looked at the chirality—the mirrored or “right” and “left” hand versions of the same molecular structure that results in two functionally distinct molecules—of amino acids and sugars. They present a new way to understand how homochirality occurs, where one mirrored side or hand outcompetes the other. The press release is available through the EurakAlert! website.
An older hypothesis for homochirality posited that a chiral molecule can self-catalyze and self-replicate in a process that includes inhibiting the other chiral molecule from replicating. Using new methods for calculating reactions, the team found that when starting with two chiral species, as the molecules self-catalyze, one gains a lead that eventually tilts the scale to its complete dominance without having to inhibit the other. Because the process can be based simply on replication and disequilibrium, homochirality might thus be a biosignature that would appear in locations bearing signs of life.
The study was supported by the Institute for Universal Biology and funded by the NASA Astrobiology Institute.
Aerosol Formation on TitanSunset on Saturn’s moon Titan reveals the atmosphere around the moon as seen from the night side with NASA’s Cassini spacecraft. Credit: NASA/JPL-Caltech/SSI
A recent laboratory study provides new insight into the atmospheric production of aerosols on Titan. Scientists used photochemistry and several mixtures of methane (CH4) and nitrogen gas (N2) to generate analogs of organic aerosols found in Titan’s atmosphere. The team analyzed the fractionation of carbon and nitrogen found in the aerosols they produced, providing clues as to how organic aerosols on Titan could act as a sink for these major elements.
Studying how stable isotopes of major elements like carbon and nitrogen form through organic chemistry on Titan could help astrobiologists better understand local and global processes on the moon.
Support for this research was provided by the NASA Astrobiology Program through NASA’s Solar System Workings element and the NASA Astrobiology Institute’s Virtual Planetary Laboratory. Additional support came from NASA grants from the Planetary Atmospheres element, Outer Planets Research element, and the NASA Postdoctoral Program at the Goddard Space Flight Center, administered by Oak Ridge Associated Universities through a contract with NASA.
The paper “13C and 15N fractionation of CH4/N2 mixtures during photochemical aerosol formation: Relevance to Titan,” was published in the journal Icarus.
Calibrating a Mass Spec for Studying Chemical EvolutionThe study focues on two calibrant series, polyalanine and polymalic acid. Credit: Forsythe et al. 2015
A recent study from the Center for Chemical Evolution will improve the accuracy and precision of data obtained by a form of mass spectrometry known as traveling-wave ion mobility-mass spectrometry.
Mass spectrometry is a prolific technique in chemistry that is used to study the chemical makeup of samples. Ion mobility spectrometry is a method for separating ionized molecules in the gas phase based on their molecular size and shape instead of their mass. For example, if two molecules had the same mass, but one was shaped like a rod and the other one was shaped like a sphere, mass spectrometry alone would not be able to differentiate them. However, coupling ion mobility with mass spectrometry would allow you to separate them based on their shape.
Mass spectrometry is an essential tool used by many astrobiologists on Earth, and has been included on numerous space missions. The team behind the study is currently using traveling-wave ion mobility-mass spectrometry to study the shape and structure of polymers that could have been precursors to protein on the early Earth.
The Center for Chemical Evolution is a joint effort supported by the National Science Foundation (NSF) and the NASA Astrobiology Program. The study, “Collision cross section calibrants for negative ion mode traveling wave ion mobility-mass spectrometry,” was published in the journal Analyst.
Dating Meteor Impacts Requires More DataLunar zircon brought back by astronauts from the Apollo 17 mission. Photo credit: Apollo 17/Nicholas E. Timms.
A new study of zircon calls to question the dating methods and limited evidence that have been used to assume the dates of meteor crashes on the early moon and Earth. The story was published by the University of Wisconsin-Madison.
Scientists at UW-Madison looked at zircons from the Vredefort crater in South Africa where the meteor collision is estimated to have occurred around 2 billion years ago. While the zircon showed signs of shock from impact, the observed ages did not reflect the age of the incident so much as the age of the magma rocks the zircon formed inside. This has lead to the assertion that more context is needed before the measured age of lunar or terrestrial zircon, stripped out of rocks, can be directly correlated with time of impact.
The study, “A terrestrial perspective on using ex situ shocked zircon to date lunar impacts,” was published in Geology and funded by the NASA Astrobiology Institute, the National Science Foundation, and the
SHRIMP and Microscopy and Microanalysis facilities at Curtin University, Australia.

Call for Letters of Application for Membership on NASA’s Science Definition Team for Ice Giants Mission Studies
Application Deadline: December 31, 2015
The Planetary Science Division of NASA’s Science Mission Directorate plans to conduct a generic study of mission options, including science and technology options, for exploring the Ice Giant planets. The study will build upon, but not be limited to, the National Research Council’s Planetary Science Decadal Survey, entitled “Visions and Voyages for Planetary Science in the Decade 2013-2022” (available at http://solarsystem.nasa.gov/docs/Vision_and_Voyages-FINAL.pdf); the intent of this study is to provide information for the deliberative process for the next Decadal Survey. Important to this study will be the establishment of a Science Definition Team to guide the technical study team. NASA invites scientists and other qualified and interested individuals at U.S. institutions to apply for membership on the Ice Giants Science Definition Team (SDT).
Members of the Ice Giants SDT will provide the technical team and NASA with scientific assistance and direction during preliminary architecture assessment of missions to the Uranus and/or Neptune systems. Near-term activities of the SDT will include the establishment of prioritized science objectives and a realistic scientific concept of operations, development and assessment of alternative architectures, including model payload/instrument suites for proof of concept, and suggestions for threshold science objectives/measurements for viable missions within resource constraints provided by NASA. NASA will use the products of this study for planning purposes. The SDT will be formed in January 2016 and will be disbanded after the work is complete, approximately one year later.
The Ice Giants SDT will:
1. Identify and prioritize science objectives to be addressed by spaceflight mission(s) based upon recommendations from the 2013-2022 Decadal Survey, but also account for recent information and current state of the science.
2. Participate in mission studies designed to address those science objectives. Aspects of this participation will include:
– Science traceability, identification of measurements, and specification of model payload
– Science concept of operations
– Participation in tradeoffs among scientific value, cost, and risk
– Ranking of alternative architectures
– Identification of enabling/enhancing technologies
3. Assist in the preparation of study reports.
All reports and output materials of the study will be made publicly available. Participation in the Ice Giants SDT is open to all qualified and interested individuals.
SDT member selection will be coordinated with the Chairs. The selected members will have demonstrated expertise and knowledge in areas highly relevant to Ice Giant science and related technologies and instrumentation. NASA anticipates the selection of approximately seven to ten SDT members. Representative(s) from the NASA Planetary Science Division, and possibly other Agency representatives, may serve as ex officio members of the SDT.

Call for Contributions in the Development of a Community-based Roadmap for NASA’s Planetary Data Services
Submission Deadline: January 5, 2016
NASA is preparing to work with the planetary science community to develop a Roadmap for its Planetary Data Services – the data and sample management architecture that supports the robotic exploration of the Solar System – particularly, the Planetary Data System. This Roadmap will address actions for the years 2017-2026. To this end, NASA is seeking input from the planetary and data science communities in the form of a Request For Information (RFI) designated NNH15ZDA012L that has been posted on NSPIRES.
The response to this RFI will be in the form of a PDF document uploaded via NSPIRES (see instructions in the full RFI on NSPIRES). Each response shall address a single topic relevant to the Planetary Data System or its potential integration with the Minor Planets Center, the Astromaterials Acquisition and Curation Office, or the Astrogeology Science Center. There is no limit on the number of responses that an individual or institution may submit.
NASA especially seeks input from the planetary and data science communities on the following topics:
1. What tools, resources, workflows, tutorials, and interfaces will future users expect or require?
2. How can the interaction between the PDS and data providers (missions and individual researchers) be improved in order to make the archiving process seamless and less costly (to both data providers and the PDS)?
3. How can the interaction between the PDS and data providers be improved to move data from the provider to the public as rapidly as possible?
4. What role should the PDS play, relative to other archiving alternatives (including scientific journals), in providing the public access to the data that is the product of NASA’s funded research and the basis of published scientific studies?
5. What is the highest priority need for integration between PDS data products and either cartographic products, sample material, or data from the Minor Planets Center (or all of them)?
6. What role should the PDS play in encouraging the development of higher-order data products and ensuring archive quality is quickly achieved?
7. Are there identifiable improvements to the current search capabilities of the PDS that would allow researchers improved access to data products and metadata?
Please refer to the full text of this RFI with instructions on NSPIRES at http://nspires.nasaprs.com/ by selecting Solicitations, choosing “Open” from the bulleted list on the left under “View Solicitations” and then searching on NNH15ZDA012L

Exploration Science Summer Intern Program
Application Deadline: January 15, 2016
The Lunar and Planetary Institute (LPI) and NASA Johnson Space Center (JSC) is hosting a special Exploration Science Summer Intern Program to build on the success of the former Lunar Exploration Summer Intern Program that was designed to evaluate possible landing sites on the Moon for robotic and human exploration missions. Over a five year period (2008–2012), teams of students worked with Lunar and Planetary Institute (LPI) science staff and their collaborators to produce A Global Lunar Landing Site Study to Provide the Scientific Context for Exploration of the Moon. The program for 2016 is designed to have the same impact on future exploration activities, but has a broader scope that includes both the Moon and near-Earth asteroids. It is a unique opportunity to integrate scientific input with exploration activities in a way that mission architects and spacecraft engineers can use. Activities may involve assessments and traverse plans for a particular destination (e.g., on the lunar farside) or a more general assessment of a class of possible exploration targets (e.g., small near-Earth asteroids).
The 10-week program runs from May 23, 2016, through July 29, 2016. Selected interns will receive a $5675 stipend to cover the costs associated with being in Houston for the duration of the program. Additionally, U.S. citizens will receive up to $1000 in travel expense reimbursement and foreign nationals will receive up to $1500 in travel expense reimbursement.
Applications are only accepted using the electronic application form found at the LPI’s Exploration Science Summer Intern website: http://www.lpi.usra.edu/exploration_intern/
