Admission is free on a first-come, first-served basis.

We also offer a monthly von Karman lecture series , and conduct weekday tours. Keep up on our latest news by signing up for JPL accounts on Twitter, Instagram, Facebook and Flickr.

Please know that in addition to "A Ticket to Explore JPL" there are many other ways to experience JPL including our monthly von Karman lecture series or weekday JPL Tours.

Based on positive feedback received last year, NASA's Jet Propulsion Laboratory, Pasadena, California, is again using an online ticketing system for the public to sign up to attend this year's "Explore JPL." During the event, JPL will open its doors to the public for one weekend. To ensure a safe, enjoyable experience, advance tickets are required.

Tickets are free but limited, and will be distributed on a first-come, first-served basis, with a maximum of five tickets per requestor. No one will be admitted without a ticket. Visitors to JPL during the event -- to be held May 20 and 21 from 8:30 a.m. to 4 p.m. -- must have their tickets in hand, and anyone age 18 or older must show a matching ID. Tickets are not transferable and cannot be sold.

The tickets -- which will be for specific time slots -- will be distributed on a first-come first-served basis online at 9 a.m. PST on Saturday, March 11, at:

https://explore.jpl.nasa.gov . The site also has additional information.

"A Ticket to Explore JPL" takes visitors through some of the marvels of robotic space exploration. Highlights include a life-size model of the Mars rover Curiosity; various robots on display; JPL's machine shop, where precision spacecraft parts are built; and the Microdevices Lab, where tiny technology is being developed to revolutionize space exploration.

Although children under 2 do not require a ticket, note that experiences at the event are not intended for very young guests.

Vehicles entering NASA/JPL property are subject to inspection. Visitors cannot bring these items into NASA/JPL: weapons, explosives, incendiary devices, dangerous instruments, alcohol, illegal drugs, pets and all types of skates, skateboards, and Segways. Bicycling to NASA/JPL is welcomed, but not inside the event, as the venues are crowded with pedestrians. Bike racks will be provided near the main entrance. No bags, backpacks or ice chests are allowed, except small purses and diaper bags. Drones are not allowed to fly over NASA/JPL under any circumstances.
