Featuring 25,000 square feet of museum displays with more and 400 space artifacts. Welcome to the home of the Space Center in Houston. If visitors didn’t know, it’s a Smithsonian Museum, hosts STEM programs for all ages and is the home of mission control and astronaut training. Mission control is what observers listen to when a rocket blasts off. Besides all the spaceship exhibits, there’s a newer exhibit called Mission Mars. Developed with the help of NASA, it focuses on the work NASA is doing now to plan for future travel to Mars. That sounds worth the ticket price right there! Finally, the best for last: Independence Plaza: This landmark attraction contains the world's only Space Shuttle replica, where it stands mounted on one of the two original shuttle carrier aircrafts.  - Jordan Dietterich of Surfside, Florida
