Common Questions

Read the most frequently asked question about tram tour timed ticketing below.

The free timed tickets were started at the request of visitors who wanted more time to enjoy over 400 things to see and do at Space Center Houston. Previously, the tour was available on a first-come, first-served basis, which resulted in long lines during busy times. We are constantly looking for ways to improve the Space Center Houston experience.
No. The timed ticket is free.

Don’t fret. We are only offering a portion of the seating of each tram tour as timed tickets online. The rest of the seats will be filled from the standby line. That line will function much as it does without timed ticketing: first-come, first-served.

Independence Plaza, presented by Boeing: Experience the historic shuttle carrier aircraft NASA 905 with the high-fidelity shuttle replica Independence mounted on top. You can tour this international landmark at your own pace. We suggest allowing about an hour and a half to explore this innovative exhibit celebrating the Space Shuttle Program. Touch interactive displays, see NASA artifacts and learn about the legacy of the Space Shuttle Program. The one-of-a-kind Independence Plaza is the only place in the world where visitors can enter a shuttle replica mounted on top of the original space shuttle carrier aircraft.

Mission Mars: Experience a virtual Martian sunset, climb into a simulated Orion capsule and feel the texture of rock cliffs inspired by the red planet in this brand-new interactive exhibit. Discover what it takes to travel to Mars, what hardware will get us to the fourth planet in our solar system and how humans might live on the red planet in the next few decades.

Starship Gallery: Home to the majority of our artifacts, walk inside the massive Skylab Trainer Module where astronauts first trained for life in space. See multiple flown spacecraft including Gemini V, Mercury “Faith” 7 and Apollo 17. Touch one of only eight moon rocks on earth available for the public to touch inside our Lunar Vault.

Elsewhere around the center, marvel at the future of deep space exploration with the movie Journey to Space in our large screen theater or the film Human Destiny about the history of America’s space program, in Destiny Theater. Be sure to get your updates on NASA’s missions to Mars in Mission Briefing Center and see what life is like on the International Space Station during our Living in Space show.

We also have at least multiple large visiting exhibits that change throughout the year. There’s always something new at Space Center Houston.
