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 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.

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.
Launched in 2007, Nasa’s Dawn spacecraft orbited and surveyed large asteroid Vesta between July 2011 and September 2012. This detailed map is the culmination of a two-and-a-half-year geological mapping campaign.
On course to collect specimens from asteroid Bennu after its launch last year, NASA’s OSIRIS-REx spacecraft will search this month for objects sharing an orbit with Earth, a bonus science opportunity to locate possible fragments of the primordial building blocks that formed our home planet.
Astronomers are using the NASA/ESA Hubble Space Telescope to study aurorae — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the solar system, Jupiter. This observation program is supported by measurements made by NASA’s Juno spacecraft, shortly to arrive at the gas giant.
