There's a lovely, geeky, cool, nerdy reciprocal relationship between NASA scientists and Hollywood filmmakers that has made for some interesting science-fact-meets-science-fiction moments at the Space Center Houston, our winner for Best Tourist Attraction. Astronauts have often credited sci-fi films with sparking their interest in science and outer space. Filmmakers, on the other hand, cite the real-life space feats by NASA that inspired them to create their movies. A longtime fan of the space program, George Lucas, for example, has shared some of the memorabilia from his films with the center including props, costumes and shooting scripts covered with handwritten notes by Lucas from his Star Wars series. (R2-D2 and C-3PO were featured stars at the recent exhibit "The Cinema of George Lucas.") Looking to experience something a little more reality-based? The space center has an ongoing schedule of ever-changing exhibits and learning camps; it's home to artifacts from NASA programs including space capsules, moon rocks and astronaut suits. There are plenty of hands-on exhibits; you can experience a fleeting sense of weightlessness or navigate the controls of a spacecraft or a lunar rover.
