NASA’s Dawn spacecraft studied Vesta from July 2011 to September 2012. Data gathered from multiple instruments aboard Dawn have been compiled into Vesta Trek’s user-friendly set of tools, enabling citizen scientists and students to study the asteroid’s features. The application includes:
— Interactive maps, including the ability to overlay a growing range of data sets including topography, mineralogy, abundance of elements and geology, as well as analysis tools for measuring the diameters, heights and depths of surface features and more
— 3-D printer-exportable topography so users can print physical models of Vesta’s surface
— Standard keyboard gaming controls to manoeuvre a first-person visualisation of “flying” across the surface of the asteroid
Vesta Trek was developed by NASA’s Lunar Mapping and Modelling Project (LMMP), which provides mission planners, lunar scientists and the public with analysis and data visualisation tools for our Moon, spanning multiple instruments on multiple missions. Vesta Trek represents the first application of LMMP’s capabilities to another world beyond the Moon. LMMP-based portals for other worlds in our Solar System are currently in development.
“There’s nothing like seeing something with your own eyes, but these types of detailed data-visualisations are the next best thing,” said Kristen Erickson, Director, Science Engagement and Partnerships at NASA Headquarters in Washington. “We’re thrilled to release Vesta Trek to the citizen science community and the public, not only as a scientific tool, but as a portal to an immersive experience that, just by the nature of it, will allow a deeper understanding of Vesta and asteroids in general.”
NASA’s Dawn spacecraft is continuing its exploration in the asteroid belt, after arriving at the dwarf planet Ceres on March 6th. As Dawn conducts its mapping and measurements of Ceres, LMMP will continue to work closely with the Dawn mission.
