Evolution of Small Ice-Silicate Bodies 2012
The 5th annual workshop on small, icy bodies took place August 8-10, 2012 at the Bear Fight Institute. The topic was the Origin, Evolution and Present Status of Small ice-silicate bodies in our Solar System. The special focus was to review and perhaps advance what is known about the small planet-like objects such as Ceres, Themis and Vesta and their fragments. A second focus was on the latest findings from the Dawn Mission, then orbiting Vesta and afterwards headed for Ceres.

Evolution of small icy-silicate bodies 2011
Another in the series of workshops on the general topic of the origin and evolution of ice-silicate bodies was held August 15-17, 2011 at the Bear Fight Institute. The specific topic was: The Themis Asteroid Family: Are they part of a disrupted Ceres-like object?
The workshop reviewed the available observational information on this family and what thermodynamic models tell us about their behavior and how water and silicates in mixes behaves in this environment. An exciting discussion on what the Dawn mission is finding was led by the Dawn deputy PI, Dr. Carol Raymond, of the JPL, which led to a discussion of what questions a spacecraft mission to the Themis family might address.
Attendees included experts on many of the major topics of discussion, including: J. Emery, J. C.Castillo, A. Rivkin, T. V. Johnson, D. L. Matson, C. Raymond, A. Davies, P. Hayne, B. Schmidt, in addition to BFI scientests Paul Hayne, T. B. McCord and J-Ph. Combe.

Evolution of small ice-silicate bodies in the Solar System 2010
The 3rd annual "Evolution of small silicate-ice bodies in the Solar System" workshop was held at the Bear Fight Institute August 6-8, 2010. The general topic was the evolution of small ice-silicate bodies. This workshop was focused on Ceres and developing a surface composition model to aid the Dawn mission in planning observation.
Such a model was developed, under the leadership of Tom Prettyman, with 14 attendees involved. Short presentations were made and long discussions were held on several related topics, including the original materials forming Ceres, where Ceres formed in the Solar System, how and when differentiation occurred, and what materials might have reached the surfaces.
This is one of the Bear Fight Institute’s small, informal, invitation-only workshops that encourage discussion among "experts" in a special, timely research topic.

Evolution of small icy-silicate bodies 2009
A workshop was held at the Bear Fight Institute 1-3 September 2009: "Evolution of small silicate-ice bodies in the Solar System." Protoplanet Ceres was the major topic. Explaining the formation, thermal evolution and present state of such objects involves very interesting chemistry and physics. There is also interest in planning space missions to these objects. Other similar objects in the solar system were discussed as well. This study is timely because of the recent modeling and observational work suggesting that Ceres is differentiated and may currently contain liquid water.
In addition, the Dawn spacecraft is in flight heading for first Vesta and then Ceres to orbit them and observe their various characteristics. Preparation is needed to interpret the returned measurements. The Bear Fight Institute is a member of the Dawn science team.

Dr. W. Farrand and Paul Hayne (UCLA) will be visiting the Bear Fight Institute 29-31 July 2009 to collaborate with Drs. McCord and Combe on NASA Mars Express Color Analysis of the MER Sites (part of MDAP).
17-19 June 2009, Dr. Jean-Philippe Combe of the Bear Fight Institute hosted a workshop on VIRTIS data analysis. Visiting scientists Drs. U. Fink and R. Carlson collaborated with the institute’s science team.
The Bear Fight Institute congratulates former student intern Garrett Heitman on his high school graduation in June 2009! We wish Garrett the best of luck working in Alaska this summer and his future plans to attend Montana State University to study engineering.
27-28 May 2009, Dr. Georgiana Kramer of the Bear Fight Institute hosted two students from the Pateros High School. Dr. Kramer discussed careers in space science research with the students and gave them hands-on training in data analysis techniques.

Evolution of small icy-silicate bodies 2008
A workshop on the theme "Icy Satellite and Small Body Evolution" was hosted at the Bear Fight Center, 18-20 February 2008. Bear Fight Center scientists were joined by scientists from NASA's Jet Propulsion Laboratory and UCLA. The workshop focussed on not only analysis and modelling of data from the Cassini spacecraft, currently orbiting Saturn, but also looked forward to data that the NASA DAWN mission will return from the asteroids Ceres and Vesta. A wide range of topics were covered, including: the role played by both short and long-lived radionuclides in icy satellite and asteroid evolution; the evolving chemistry of satellite oceans; projects deemed necessary to aid interpretation of DAWN data; the interaction of water and hot silicates in planetary mantles; and the modelling of cryovolcanic processes.
