If anyone sees Raymond E. Arvidson, PhD, walking the halls of Washington University wearing Microsoft HoloLens, then he’s not entirely walking on Earth. HoloLens combined with OnSight, a software tool developed by NASA’s Jet Propulsion Laboratory in collaboration with Microsoft, allows Arvidson to be absorbed in the Martian landscape conducting field research. Arvidson may actually be walking on university flooring, but the software is allowing him to virtually walk on Mars with NASA’s Mars rover Curiosity. In his role as Curiosity Surface Properties Scientist, Arvidson is planning Curiosity’s next move.
