This tour was an included part of Our Deep South & Texas Coach Tour. The first thing to realise is that your are actually at a Visitor Center, NOT the NASA Johnson Space Center, parts of which you are bused to from the VC. The VC contains not only a cafe, gift shop,etc, but quite a number of interactive displays and a Space Shuttle Exhibit. There is also an excellent Saturn V exhibit in a large building , plus some large rocket exhibits, but they are away from the VC and require bus transportation. You can also get to visit the Astronauts Training Complex and Mission Control Center, which are part of the working Johnson site, but once again, you require bus transportation. The big problem is they just don't have enough buses, and if you are there in the afternoon, like we were, when its at its busiest, you spend a lot of time waiting in queues to get you round the site. WE managed to get to see Mission Control, where we had an excellent talk about its history, its set-up and whilst we were there could see them tracking the International Space Station, which was most interesting. We also visited the Saturn V building, which is a MUST, excellent and informative displays here. We also got to visit the Shuttle, but as the center closes at 5pm, and we never got there til just after 1.15pm, missed a lot of good exhibits. As with all these places found the shop/ cafe prices high. Well worth a visit, but give yourselves at least 6/7 hours.
