Advances in 3-D modelling are leading to new ways of visualizing the surface of the Moon, Mars and other objects in the solar system. Lunar and Planetary Laboratory professor in practice Steve Kortenkamp describes how the technology is allowing him to teach astronomy to students who are blind.

Steve Kortenkamp spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.
