On Friday, January 23, Miles O’Brien will take “NewsNight” viewers on an exclusive 3-D tour of Mars. The rover there has three-dimensional cameras, and we will present the first ever 3-D TV transmission of the Martian landscape. Make sure to get your 3-D glasses in time to experience this television first. When using 3-D glasses, remember that the left eye should be red, and the right eye blue.
