Timed Ticketing

Timed tickets for tram tour to NASA are here

Movies like The Martian and Apollo 13 gave you a taste of life in NASA’s bustling hub of activity, Johnson Space Center. When you visit Space Center Houston, go behind the scenes of all that innovation yourself.

A limited number of free timed tickets for specific tour times is now offered on every tram tour to NASA Johnson Space Center.

Timed ticketing means you can avoid the stand-by lines during the busiest times of day and reserve your time to see the vibrant past and exciting future of space exploration.

We heard your concerns about the tram tour waits during busy seasons at Space Center Houston. Bear with us as we implement this new program to help you have the best experience possible and see more of Space Center Houston.

How it works


Before you visit, a free timed ticket can be selected on our website for a designated time. Tickets must be either printed prior to arrival or presented on your mobile device to the Crew Member at the tram tour loading area. Your ticket for the tram tour reserves a seat for the time frame selected. Tickets are valid only for the time specified, and you must arrive AT LEAST 15 minutes prior to your scheduled tour time. Late arrivals cannot be guaranteed entry at the time specified on your ticket.

In the event that you miss your scheduled tour, we will make every reasonable accommodation, which may include but is not limited to a seat on the next available tour if space is available; or placement in the stand-by line. If you miss your timed entrance, please see a Crew Member for assistance.

Please note that this is an open-air tram tour and riders are subject to weather conditions. The tour also could be postponed or cancelled if weather conditions are unsafe. Please monitor weather and plan accordingly. The tram tour visits NASA, which is a working government facility and entrance to the center and its various buildings are subject to availability. Tours may be rerouted at a moment’s notice or cancelled.

If your timed ticket is during inclement weather, we will make every reasonable accommodation, which may include postponing all timed tickets until inclement weather has passed or we will place the ticket holder in a stand-by line. Once you select your timed visit and proceed to check out, you will receive an email confirmation with an electronic version (PDF) of your ticket attached.

What to do on your visit

On the day of your visit to Space Center Houston, bring your printed or mobile-device version of your timed ticket for the tram to the tour entrance at the back of the building. Arrive AT LEAST 15 minutes before your tour is scheduled to begin. Present your timed ticket to the Crew Member waiting near the queue.

If you lose your ticket or forget it at home, don’t despair. We also will accept the electronic (PDF) version of your ticket shown on your smartphone or tablet, or you can go to the timed ticket stations at the Membership Desk and ask to have it reprinted. The desk is located to the left as you enter from the front of the building, just behind the Stellar Science Stage.

Two other ways to get a timed ticket

Spontaneity is the spice of life. Sometimes, that leads to an impromptu trip to bask in the wonders of space at Space Center Houston.

If you are already at the center but do not have a timed ticket, there are two options to obtain one.

Upon arriving inside the center, go first to the timed ticket stations at the Membership Desk, which is located to the left of the main entrance behind the Stellar Science Stage. There, a Crew Member can assist you in reserving a spot on one of the tram tours that day. Timed tickets are limited on these tours, however, so make sure to reserve your spot early.

The second option is to go to our website at spacecenter.org/nowait and reserve a spot through your mobile device. Once you’ve done this, present the email confirmation and the electronic ticket version (PDF) at the tram tour queue at your designated time.
