'Destination: Mars': NASA Readies Virtual Red Planet Treks (with 'Buzz Aldrin'!)

NASA has announced that the Kennedy Space Center (KSC) Visitor Complex in Florida will host a new exhibit called "Destination: Mars" that will let visitors walk around on the Martian surface without ever leaving Earth. For the "mixed-reality" experience, visitors will don the HoloLens headset that shows realistic, 3D views of the Red Planet's surface. The Red Planet tour is led by Apollo 11 moonwalker Buzz Aldrin — or at least, a hologram of Aldrin.
