Monday, June 15, 2015 PLENARY SESSION: WELCOME AND THE DEEP HISTORY OF A CARBON ATOM MON ORAL 8:00 a.m. Grand Ballroom

8:00 a.m. Opening Remarks John Grunsfeld, NASA Headquarters

8:10 a.m. The Deep History of a Carbon Atom

Moderator: Jamie Elsila

Panel Members: Karen Meech Andrew Steele Michael Callahan

Primo Levi’s short story, “The Story of a Carbon Atom,” tracked the path of a carbon atom. The story begins, “Our character lies for hundreds of millions of years, bound to three atoms of and one of calcium, in the form of limestone: it already has a very long cosmic history behind it, but we shall ignore it.” This session will tell the long cosmic history of that atom, beginning with the formation of carbon in a star, and ending with the atom involved in

prebiotic chemical reactions on Earth.

PLENARY SESSION: SUSTAINED HABITABILITY ON A DYNAMIC EARLY EARTH 9:15 a.m. Grand Ballroom

Speaker: James Kasting

Panel Members: Timothy Lyons, Noah Planavsky, and Chris Reinhard

We know something about the habitability of early Earth, but many questions remain. Convincing evidence for life dates back to only 3.5 Ga, whereas Earth itself is a billion years older. Despite the faintness of the young , conditions near Earth’s surface may have been too hot for life for hundreds of millions of years, either sporadically as a consequence of impact or more generally as a consequence of high atmospheric CO2 levels. The Archean

(2.5–3.8 Ga) was more clement, but the discrepancy between oxygen isotope data from cherts, which suggest high surface , and evidence for repeated glaciations has not been satisfactorily resolved. Climate may have been stabilized during this time by a combination of feedback loops involving both CO2 and CH4. Like now, was mostly biological in origin, so the climate control system could be described as being “Gaian.” The rise of atmospheric O2 near 2.4 Ga probably triggered the glaciations that occurred at that time, although some authors have argued that this causality was reversed. The resulting Proterozoic climate was less stable and “boring” than previously thought, as glaciations have now been reported at ~1.8 Ga and ~1.2 Ga, in addition to the well-known

Snowball Earth events of the Neoproterozoic. Better empirical constraints on surface and on atmospheric O2 and CO2 are needed to reach consensus on what the early Earth environment was really like.

A 40-minute presentation by J. Kasting will be followed by 20 minutes of Q and A and open discussion with the speaker and panel.

THE SCIENCE AND ENGINEERING OF PLANETARY PROTECTION: OWNING THE ISSUE 1:45 p.m. Salon A2

Chairs: Ariel Anbar Penelope Boston

Planetary Protection is a critical requirement for many space missions, but sometimes a source of contention and

misunderstanding in the and science community. With sample return missions from Mars, , and other astrobiologically interesting targets in the offing, it’s time to come to grips with this issue in ways that are meaningful, implementable, and cost-effective. How can we do this as a community? This session will include panel discussion, audience dialog, and topical breakout sessions to improve community understanding and engagement with the technical challenges and scientific implications of Planetary Protection, and to brainstorm innovative, practical, and defensible solutions. Bring your creativity to this lively session and engage in this critical community discussion.

8:10 a.m. Real Life or Fantasy: Biosignatures or Abiosignatures in Astrobiology

Moderator: Sonny Harman

Panel Members: Shawn Domagal-Goldman ORALSTUES

Abigail Allwood

One of the fundamental pursuits of astrobiology is to find life elsewhere — a pursuit often complicated by natural processes masking or mimicking signals that we would normally attribute to the presence of life. Common life-detection criteria and a range of biosignatures and abiosignatures across several disciplines will be introduced.

A panel discussion will follow with topics such as historical false positives, current detection criteria, and the future strategies for identifying robust indicators of life and distinguishing these from abiotic mimics.

PLENARY SESSION: THE ORIGIN AND SUBSEQUENT EVOLUTION OF LIFE 9:15 a.m. Grand Ballroom

Moderators: Nicholas Hud Rachel Whitaker

Recent years have witnessed dramatic advances in our understanding of the early steps in the transition from a prebiotic world to a world transformed by a biotic component. These early steps are presumed to include the evolution of collectively autocatalytic networks of molecules, as well as the evolution of protocells that define the boundary between living and non-living matter.

Since the earliest cellular life, innovations caused by gene duplication and divergence, novel gene fusions/fission, and transfer of genes between phylogenetically distinct groups have led to an explosive diversification of the metabolic and regulatory networks within cells, enabling colonization of new environmental niches as well as new

mechanisms for cooperative interactions between cells. The hierarchy of life — genes within genomes, organelles within cells, cells within organisms, and organisms within societies — is not a starting condition of the evolutionary process, but an outcome of a series of major transitions in which units of low complexity combine to form units of high complexity. Ongoing revolutions in genomics and informatics are giving new insights into the processes by which such transitions occur.

Wednesday, June 17, 2015 PLENARY SESSION: UNDERSTANDING AND RECOGNIZING EXOPLANET HABITABILITY 8:00 a.m. Grand Ballroom

8:00 a.m. Daily Announcements

Moderators: Rory Barnes Victoria Meadows

Habitability is a measure of an environment’s potential to support life. For exoplanets, the concept of habitability can be used broadly to inform our calculations of the possibility and distribution of life elsewhere or as a practical tool to inform mission designs prioritize specific targets in the search for extrasolar life.

Although a planet’s habitability depends critically on the effect of stellar type and planetary semi-major axis on climate balance, many additional factors have been identified that can affect a planet’s environment and its potential ability to support life. Key abiotic processes affecting the resultant planetary environment include photochemistry, stellar effects on climate balance, atmospheric loss, and gravitational interactions with the star. WED ORALS

Understanding these processes will help us identify exoplanets that are most likely to be habitable, and will illuminate global characteristics of habitable planets that may be observable.

Astronomical observations to assess habitability may include searching for the presence of surface liquid using specular reflectance, or “glint”; determining surface temperature and pressure; and more comprehensive assays to

detect the presence of greenhouse gases and assess planetary climate. In the near future, groundbased surveys and the NASA K2 and TESS missions will discover rocky exoplanets in the habitable zones of nearby stars. Larger telescopic facilities, including planned large groundbased facilities, the James Webb Space Telescope, and direct imaging missions under study such as AFTA, Exo-C, and Exo-S will allow us to study these nearby targets via multi-wavelength photometry and spectroscopy to search for signs of habitability and life.

PLENARY SESSION: IMPROVING ASTROBIOLOGY EDUCATION THROUGH DIGITAL LEARNING RESEARCH 9:15 a.m. Grand Ballroom

Speaker: George Siemens

Moderator: Daniella Scalice

The astrobiology community has been incorporating digital to support communication across space,

time, and discipline since its inception. These technologies have been extended in more recent years to serve learners in a variety of settings, such as Massive Open Online Courses (MOOCs), virtual field trips, and eMentoring programs, to name just a few.

As more astrobiologists adopt digital-learning modalities, important questions arise regarding the role of technology, teaching quality, new pedagogies, and how to foster creativity and collaboration. These questions can best be addressed by focusing on insights and opportunities offered by analyses of existing learning sciences research, and studying how it informs instruction in digital environments.

Thursday, June 18, 2015 PLENARY SESSION: PLANETS IN PERSPECTIVE: WHERE’S THE ENERGY? 8:00 a.m. Grand Ballroom

8:00 a.m. Daily Announcements

8:10 a.m. Planets in Perspective: Where’s the Energy?

Moderator: Britney Schmidt

In the previous two decades, planetary exploration has observed one mantra: “Follow the Water.” However, as

the field of astrobiology has matured, particularly with respect to planetary environments and the broad range of possible ways that potentially habitable planets have formed and evolved, we may be standing on the precipice of a shift toward “Follow the Energy.” This theme recognizes that planetary processes are the likely precursors to life,

and inspires new ways of assessing the habitability of a planet based not only on its ingredients, but also on a holistic assessment of its systems and cycles.

PLENARY SESSION: SEEKING ASTROBIOLOGY INPUT TO LANDING SITE SELECTION 9:15 a.m. Grand Ballroom

Moderators: Dave Beaty Lindsay Hays

The proposed Mars 2020 rover mission has two objectives of high importance to astrobiology: (1) to carry out in situ exploration operations seeking the signs of past life, and (2) to collect samples of martian material and seal them in individual tubes for possible return to Earth for detailed analysis, including assessment of potential biosignatures.

ORALS Mars has varied geological terrain. In order to maximize the chances of making a major astrobiological discovery, it is crucial to select a landing site that offers the highest chances of addressing these life-related objectives. Although the formal landing site selection process is open to all, the purpose of this session is to solicit specific THUR input from the astrobiology community about the desired attributes of potential landing sites and the rationale for prioritizing these attributes. This session seeks to foster broader intellectual inputs from the astrobiology community. The results of this discussion will be provided to the landing site selection committee.

8:10 a.m. Increasing and Measuring the Impact of Education and Public Outreach

Chair: Lev Horodyskyj

The Astrobiology Community shares a strong motivation to improve the STEM knowledge and skills of today’s youth, and we are dedicating increasing amounts of our time and energy to education and outreach work.

Scientists and educational project leads can benefit from a deeper connection to the value of evaluation, how to work with an evaluator, and how to effectively integrate evaluation into projects to increase their impact.

In this workshop we will introduce a method for evaluating educational activities, including public talks,

professional development workshops for educators, youth engagement programs, and more. You will walk away with a clear understanding that measuring impact goes beyond reporting participant counts. Instead, measuring impact requires thoughtful consideration throughout the project cycle, and the willingness to use data to improve.
