How well do you know The Earth, Asteroids, Comets?
Abstract
The U.S. Rosetta Project is the NASA contribution to the International Rosetta Mission, an ESA cornerstone mission. The mission will arrive at its target, comet 67 P/Churyumov-Gerasimenko, in 2014, and escort the comet around the Sun for the ensuing 17 months. Along the way, the mission has encountered two asteroids: 21/Lutetia, and 2867/Steins, and enjoyed gravity assists at Mars and several at the Earth. The challenge for outreach coordinators is to convey the excitement of the mission, the manner in which its experiments gather and interpret data, provide context for those interpretations, all in an engaging fashion, without heavy use of camera images -- the camera not being among the NASA contributed instruments. In other words, because the US Rosetta Project expects to present the data and results from: an ultraviolet spectrometer, a plasma instrument, and a microwave spectrometer, outreach is presented with the special challenges of engaging the public in data which at least visually is less accessible than that of camera images. The project has turned to online games, interactive simulations, animated cartoons, and virtual labs to provide a visually stimulating way to explain: how scientists determine the age of asteroids; the context of a timeline of Earth geologic history with which to understand the relative position of the ages of any given asteroid to some event on Earth; a model of the solar system that goes from our Sun to the next Star to understand the spatial distances covered by comets in their journey around the Sun; and a model of early solar system evolution in which to understand the possible scenarios of solar system evolution that comets can help us sort out. In this paper we will present these simulations, even if some of them remain in the beta-development phase at the time of the meeting itself. Work at the Jet Propulsion Laboratory, California Institute of Technology, was supported by NASA. Rosetta is a joint collaboration between NASA and the European Space Agency.
