My month-long road trip across the United States wrapped up in Houston. I was flying out to Mexico next, and Houston offered the most diverse and affordable flight options for international travelers. While Houston isn’t primarily known as a major tourist hub, the NASA Space Center located just outside the city limits is an absolute must-visit.

Houston, The Space City
Houston is the largest city in Texas and the fourth-largest in the U.S., boasting a population of about 2.3 million. Located in the southeast near the Gulf of Mexico, it is world-renowned as a major center for the energy and oil industry. Thanks to the NASA space center, it also plays a crucial role in the aerospace sector, earning it the famous nickname “Space City.”
NASA Johnson Space Center
Widely known as Space Center Houston, the official name of the working facility is the Johnson Space Center. It serves as NASA’s headquarters for human space exploration, handling astronaut training, spacecraft research, and flight control. From the Apollo program to the current operations of the International Space Station (ISS) and the future Artemis missions, it remains the absolute heart of human spaceflight.
The Artemis Program, initiated in 2017, is NASA’s latest crewed space exploration plan. While Artemis III was originally expected to return humans to the lunar surface earlier, recent NASA updates as of 2026 have pushed the target launch to mid-2027. Space Center Houston is not only an active research hub but also an interactive museum offering exhibits on the ISS, Mars, and the Moon. Visitors can view the largest meteorite ever found on Earth and even touch a piece of Mars—a rock fragment blasted off the Martian surface by a meteor impact that eventually landed on our planet.

NASA Tram Tours
While the museum exhibits are incredible, the Tram Tour is an absolute must-do experience. General admission includes access to two different tram tours.
The first is the Rocket Park Tour, where you can marvel at the Saturn V—the massive rocket that sent humanity to the moon during the Apollo program. The F-1 engines used on the Saturn V are the most powerful single-chamber engines ever created. The “V” in Saturn V stands for the five F-1 engines that power it.
The second option is the Astronaut Training Facility Tour, which takes you inside the actual buildings where astronauts prepare for space. Both tours are free with basic admission, but keep in mind that the final tram departs at 3:00 PM. Since spots are allocated on a first-come, first-served basis, I highly recommend heading straight to the Guest Services desk upon arrival to secure your Astronaut Training Facility ticket and check the Rocket Park schedule.
Inside the training facility, you can see spacecraft currently under development and observe real NASA engineers and staff at work. It’s a rare, behind-the-scenes look that you won’t easily find anywhere else.
Apollo and Lunar Exhibits
After completing the tram tours, head back to the main museum to explore the dedicated Apollo and lunar exploration exhibits. The center features highly realistic dioramas showing the first astronaut stepping onto the lunar surface, along with actual exploration modules and stunning visuals of the bright blue Earth against the pitch-black void of space.
You will also find real moon rocks and lunar soil samples brought back from the Apollo missions. Analyzing these samples revealed that the isotopic ratios of certain elements are identical on Earth and the Moon, strongly supporting the hypothesis that the Moon was once part of Earth. Because these samples could easily oxidize upon contact with Earth’s water- and oxygen-rich atmosphere, they are carefully preserved inside display cases filled with pure nitrogen gas.
Next up is the exhibit on Skylab, America’s very first space station. Skylab was used to study how humans adapt to long-term microgravity and how solar activity affects Earth. You can also view a replica of the Skylab trainer used by astronauts to prepare for their missions. Seeing the display of an astronaut spinning mid-air in zero gravity was particularly memorable.
Space Shuttle Independence
Outside the main building lies Independence Plaza, an outdoor exhibit featuring a full-scale space shuttle replica, the Independence, mounted on top of an actual Boeing 747 Shuttle Carrier Aircraft (SCA).
The Independence replica was built to test the safety and reliability of transporting space shuttles on the back of a 747, meaning its shape and dimensions are completely identical to a real space shuttle.
This is the only place in the world where you can enter both a space shuttle replica and the original carrier aircraft it sits on. The shuttle interior isn’t overwhelmingly large, so it’s a fairly quick walkthrough. Don’t miss the engineer’s inside joke written on the coupling area between the shuttle and the plane: “Note: Black Side Down.”
SpaceX Falcon 9
Right next to the shuttle in Independence Plaza is the Falcon 9, the world-famous launch vehicle by SpaceX. It is considered an aerospace masterpiece that essentially cemented SpaceX’s current industry dominance. Similar to the Saturn V’s naming convention, the Falcon 9 gets its name from its nine engines.
It holds immense historical significance as the world’s first orbital-class reusable rocket. The specific Falcon 9 exhibited here actually flew a NASA mission and was successfully recovered afterward.
Space Center Gift Shop
Finally, the Space Center Houston gift shop is much larger than expected and packed with diverse merchandise. NASA’s globally beloved brand image makes their souvenirs highly desirable. A t-shirt playfully tweaking the famous quote from “Houston, we have a problem” to “Houston, I am the problem” makes for a hilarious souvenir or a witty baby shower gift.
Final Thoughts
Space Center Houston truly is the heart of NASA’s human spaceflight program. With its incredible tram tours to the astronaut training facilities and Rocket Park, plus extensive exhibits covering the ISS, Mars, lunar missions, the Space Shuttle, and the SpaceX Falcon 9, it offers a world-class experience. If you have even the slightest interest in space, it is highly recommended.
