Virtual space travel MSNBC

It hit me while I was looking at the stereo image of Opportunity’s landing site through 3-D glasses: This is cool. This is a place I’d like to go. I can almost make out the trail I’d take over the hill. Is that the feeling that will drive humans to the moon, Mars and beyond? Or will it instead drive the creation of more capable robots in space, and better virtual-reality systems here on Earth?
