In their 11.30am (PST) press conference, the NASA/JPL team started with Ray Bradbury - playing a clip of him from the 1971 "Mars and the Mind of Man" symposium - and concluded with a short video showing Ray's last visit to JPL in 2009, when he was shown models of Mars rovers and was allowed to drive one of them in simulation.
