“Is it real?” I ask. I’m looking around at the landscape of Mars, where a dusty, rocky desert stretches in every direction, reddish mountains rising in the distance. It looks so vivid, so strangely plausible that it’s hard to believe that I’m actually looking at the surface of another planet and not the set of a sci-fi movie.
The gentleman who works for Microsoft assure me that it is, in fact, real—depending on how you think about it. I’m currently wearing a prototype version of the HoloLens, a new augmented reality headset announced yesterday by Microsoft, and exploring real three-dimensional images collected from the Mars Curiosity rover using a tool called OnSight.
