John Adams: If you wish to study the underlying causes of a specific disease, you start by examining an animal model that would simulate the human condition. If you want to study a subset of geological events on earth, also known as Biosphere 1, you might design a miniature system, but what do you do if you want to study the B1's entire complex geology, environment and ecology?  Well, you build Biosphere 2. And so, in 1987 a vision was born, to assemble steel, concrete, soil, sea water, and plants to build a model of B1 consisting of five biomes.  For two decades, John Adams has helped drive the evolution of Biosphere 2 through positions of progressive responsibility and oversight. Today as Biosphere 2’s Deputy Director Adams holds responsibility for planning and direction of site operations and Under the Glass activities, serving as B2's primary spokesperson and media contact, overseeing biome management, energy management and facilities maintenance and setting the vision for public outreach.

11 a.m. - 1 p.m. Asteroid Detection in our own Backyard
Eric Christensen, Catalina Sky Survey, University of Arizona Steward Observatory, Mt. Lemmon

Eric Christensen is a staff scientist in the University of Arizona (UA) Lunar and Planetary Laboratory, and he is the Director of the UA Catalina Sky Survey (CSS). CSS is a NASA-funded project that searches for and discovers comets, asteroids, and near-Earth objects (NEOs), specifically potentially hazardous asteroids that may pose a threat of impact. The NEO Observations Program is a result of a United States 1998 congressional directive to NASA to begin a program to identify 1 kilometre or larger objects to around 90 percent confidence level or better. CSS, located in the Catalina Mountains north of Tucson, carries out these searches using a 1.5 meter f/2 telescope and a 68 cm f/ 1.7 Schmidt telescope. In 2005, CSS became the most prolific NEO survey surpassing Lincoln Near-Earth Asteroid Research (LINEAR) in total number of NEOs and potentially hazardous asteroids discovered each year since.

1 p.m. - 3 p.m. Asteroid Sampling
Tim Swindle, University of Arizona Lunar and Planetary Laboratory, OSIRIS-REx mission

Tim Swindle is the Head of the University of Arizona (UA) Department of Planetary Sciences and the Director of the UA Lunar and Planetary Laboratory. His area of specialization is cosmochemistry and he uses measurements of the noble gases in extraterrestrial materials (lunar samples and meteorites) to study the evolution of the solar system. Additionally, he is a collaborator on the OSIRIS-REx mission. This space mission, launching in 2016, will send a spacecraft to the asteroid Bennu, collect a sample, and return it to Earth in 2023. OSIRIS-REx seeks answers to questions that are central to the human experience: Where did we come from? What is our destiny? Bennu, an asteroid that records the earliest history of our Solar System, may contain the molecular precursors to the origin of life and the Earth’s oceans.
