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?.
Just got back from KSC. The new Atlantis exhibit is breathtaking. Simply the best of the shuttle displays around the country. The Shuttle Training Experience is still a great attraction. The whole visitor complex has undergone an extensive update since I last visited in January 2011, and is worth a visit - multiple if you can.
I was down at KSC for the launch of Discovery on STS-120, exactly 6 years ago tomorrow (October 23, 2007). Though we don't launch the shuttle any more, a large rocket launch is still definitely worth a trip to the east coast of Florida. Someday soon, hopefully, the US will once again have manned missions launching from KSC.
The biggest issue with NASA itself sponsoring a pavilion at EPCOT is that government agencies are not allowed to spend money in this way. It would be considered marketing, which is illegal for taxpayer funds. The military branches get around this by classifying their marketing as recruiting. Many of the EPCOT pavilions have natural connections to US departments and agencies - The Land to the Dept of Agriculture, UoE to the Dept of Energy, M:S to NASA, Test Track to Dept of Transportation... They can't spend money like this. I've researched this at work for NASA, and found that Disney and NASA can exchange things in kind. For example, in exchange for NASA allowing a Buzz Lightyear onboard STS-124, Disney agreed to use NASA and it's logos at M:S, show launches, etc. That is the extent of what Disney and NASA have done together recently.
As someone stated earlier, the KSC Visitor Complex is operated by the Delaware North Corporation, and does not use a cent of taxpayer money. It is all privately funded - hence the $50 entrance fee. The Smithsonian Institute, by comparison, is funded by a combination of taxpayer money, private donations, and the Smithsonian Trust...which is why SI museums are free.
