What Travellers Say
Reviews Summary
Visitors consistently praise the JPL tours as an inspiring and educational experience, highlighting the knowledgeable guides and the impressive scale of the facility. The chance to see where space missions are assembled and controlled is a major draw. Some visitors wished for more time at certain exhibits, especially in larger groups, but overall, it's considered a 10/10 experience for anyone interested in space exploration.
"Bobby & Curtis of NASA were so helpful, educated, inspiring on the JPL visit. They explained the science history and details of JPL relative to other NASA hubs. I really appreciate walk to the mars rover, rocket lab and more!
Brandon of Emerging LA & Sunset Ventures was my host - thanks for coordinating the group!
I used to live at NASA Moffett in Mountain View, near Google in 2016 when I was a Google Scholar for AI research on self driving cars / machine vision via Dr. Ray Kurzweil’s collab with NASA
So messed to be inspired by Science again —- #ScienceIsReal
I post mostly on @LunaOfLA my STEM adventures"

"I’ve been to JPL twice—once was to get a tour from a friend who worked there, another to attend one of the “official” JPL tours with a guide employed by JPL (event pictured).
Our tour guide was FANTASTIC and such great charisma and attitude the entire 2.5-hour tour. He was great, and as someone who works in the guiding industry, I really appreciated his performance.
The tour begins with a movie about JPL—its mission and flagship satellites and science, a tour of the visitor’s center, and some great photo opps with scale models of Explorer-1, Voyager, and Cassini. There’s also a little aerogel cube which I thought was super cool.
Next, we headed over to the high bay to see the clean room where they assemble spacecraft. ASTHROS is pictured in my review.
The final stop on the tour was the Mission Control room where the Deep Space Network is monitored. There are three sites to monitor data from missions beyond the orbit of our moon (e.g., JWST, Juno, Voyager 1,2, etc.) at Goldstone, Madrid, and Canberra. We got the story of the “lucky peanuts” and could even see the mission command center which is broadcast LIVE during rover missions (the scenes of all the scientists high-fiving come from that room!)
My only point of constructive feedback is that it would have been nice to spend more time at the clean room view and look at some of the exhibits/displays there. I think because our group was so large (30+), we had to rush a bit between stopping points. Otherwise, this was a 10/10 experience. It’s such a privilege to get to see the amazing work and science being done at JPL!"

"If NASA is the cool kid who goes to space parties, JPL is the nerdy friend who actually gets them there on time and does their math homework for fun. Walking around JPL feels like being in a sci-fi movie where the budget went into brains instead of costumes. Everyone’s casually working on “side projects” like landing a robot on Mars or figuring out how to fly helicopters in thin atmospheres, while I can barely get my Wi-Fi router to connect.
Their gift shop? Unreal. Where else can you buy socks with Mars rovers on them and feel like you’re supporting interplanetary exploration instead of your sock drawer?
The only downside: zero chance of getting recruited as an astronaut. JPL doesn’t send people into space…they send machines. So unless you can download yourself into a rover, best you can do is admire from Earth while Perseverance lives your dream.
Overall, 10/10 would trust them to babysit my child, my dog, and definitely my satellite."
