Located about 30 minutes from downtown Houston, the Johnson Space Center is definitely worth a visit if you are in town. Makes sense, as Houston has become synonymous with space travel. As you often hear astronauts call out to Houston.
The only way to really get there is by car, as it would take a very long time by public transportation. Though, there is a $6 fee for parking, but the web site does not mention this at all.
The Johnson Space Center has a museum and a tram tour around it, and both are worth doing. The museum has displays of past spacecrafts and history on space travel itself. There are former astronauts who give tours of the museum. They can be interesting to listen to, but can take up some time.
Then there is the tram tour, which takes you to Rocket Garden and either Mission Control or Building 16. The downside is that it is weather-permitting. So if it rains outside, the tour will be delayed. And any one that has just started, will have to turn back and return to the visitor center, and go back of the line for the tram.
Rocket Garden has a few spacecrafts on display, along with the huge Saturn V rocket stored indoors. And Building 16 is where the flight simulator takes place, as well as the software and hardware checks, which does not seem as interesting as the idea of visiting Mission Control, which I assume, is where "Houston" is located. That can be very disappointing.
But overall, the Johnson Space Center is a very nice place to visit, with interactive exhibitions and a worthwhile museum, something for everyone. Just hope that there is no rain in the forecast when visiting there. And definitely give yourself at least 4 hours at the place, more if you have kids, if they really like the place.
