I've never understood why EPCOT has never had a NASA pavillion where NASA could showcase some of their neat technologies, Robotics, Remote Sensing, Energy technologies, I've always thought a program a rover attraction would have lines out the door in much the same way 'Sum of all Thrills' does, Especially if they have a REAL rover there on a simulated Moon/Mars landscape. Moon probably better for show purposes as lightspeed delay is 1.3 second in each direction, Mars is 8 minutes 20 seconds.
Show people just how tricky programming a rover is with the lightspeed delay in sending and acknowledging commands, Have a periodic live feed to the ISS via Ham Radio, Have FIRST and Vex Robotics teams demonstrate their robots. Have live feeds from missions etc.
Yes I know KSC has a visitors center DW and I are members of the Commanders Club and we were there for STS-135, But how many people make the trip to KSC?.
